TECHTARGET, INC.

Our Company

        We are a leading provider of specialized online content that brings together buyers and sellers of corporate information technology, or IT, products. We sell customized marketing programs that enable IT vendors to reach corporate IT decision makers who are actively researching specific IT purchases. We operate a network of 3536 websites, each of which focuses on a specific IT sector, such as storage, security or networking. IT professionals rely on our websites for key decision support information tailored to their specific areas of responsibility. We complement our online offerings with targeted in-person events and three specialized IT magazines that enable advertisers to engage buyers throughout their decision-making process for IT purchases.

        As IT professionals have become increasingly specialized, they have come to rely on our sector-specific websites for purchasing decision support. Our content enables IT professionals to navigate the complex and rapidly changing IT landscape where purchasing decisions can have significant financial and operational consequences. We employ over 100 full-time editors who create more than 20,000 pieces of original content per year tailored for specific audiences. We complement this content with targeted information from our network of more than 225 outside industry experts, member- generated content and extensive vendor-supplied information. We have a large and growing base of registered members, which totaled over 4.5approximately 4.9 million as of DecemberMarch 31, 2006.2007.

        The targeted nature of our user base enables IT vendors to reach a specialized audience efficiently because our content is highly segmented and aligned with the IT vendors' specific products. Since our founding in 1999, we have developed a broad customer base that now comprises more than 1,000 active advertisers, defined as customers who placed business with us in 2006, including Cisco, Dell, EMC, Hewlett Packard, IBM, Intel, Microsoft, Oracle, Research In Motion, SAP and Symantec. We delivered more than 3,400 advertising campaigns in 2006, and our average quarterly advertising renewal rate for our 100 largest customers was 92% in 2006. We also supplied more than 1.1 million sales leads to IT vendors in 2006.

        We generated revenues of $79 million in 2006, up from $67 million in 2005. Over the same period, we grew our operating income from $6 million to $13 million.

Industry Background

        There is an ongoing shift from traditional print and broad-based advertising to targeted online advertising, causing advertisers to reallocate substantial portions of marketing budgets to online advertising. We believe there are three major trends driving this shift. First, advertisers' desire to reach customers efficiently has led to the development of market-specific content channels, in particular, market-specific websites, which increase advertising efficiency by enabling advertisers to market specifically to the audience they are trying to reach. Second, the Internet is improving advertisers' ability to measure and increase return on investment, or ROI, by enabling advertisers to track individual user responses to their marketing programs. Third, the Internet is increasingly critical in researching large, complex and costly

purchases, as both the quantity of information and the availability of search engines and directories on the Internet enable potential purchasers to obtain information efficiently from many sources.

        Corporate IT professionals increasingly are demanding specialized websites, events and print publications tailored to the sub-sectors of IT solutions that they purchase. Similarly, IT advertisers seek high-ROI marketing platforms that provide access to the specific sectors of IT buyers that align with the solutions they sell. We believe that traditional IT media companies with primarily print-based revenue models have encountered difficulties in responding to these trends. These companies typically offer print publications with large circulations and broad content, associated websites with a similarly broad content focus, and large industry trade shows. We believe these offerings do not enable IT professionals to search efficiently for information related to their specialized IT purchase requirements, and minimize the likelihood of a vendor reaching a buyer while he or she is actively researching the purchase of a solution that falls within the vendor's particular market sector. Consequently, there is a need on the part of both IT buyers and IT vendors for highly specialized media offerings that increase efficiency for both parties.

Our Solution

        Our specialized content enables IT vendors to reach corporate IT professionals who are actively researching purchases in specific IT sectors. Our solution benefits from the following competitive advantages:

•

Large and Growing Community of Registered Members.  We have built a registered member database with detailed business information on over 4.5approximately 4.9 million IT professionals. We have collected detailed business and technology profiles on all of our registered members, which allows us to provide them with more specialized content and provide our advertisers with highly targeted audiences and sales leads.



•

Strong Advertiser Relationships.  Since our founding in 1999, we have developed a broad customer base that now comprises more than 1,000 active advertisers, including Cisco, Dell, EMC, Hewlett Packard, IBM, Intel, Microsoft, Oracle, Research In Motion, SAP and Symantec.



•

Substantial Experience in Online Media.  We have over seven years of experience in developing our online media content, with a focus on providing targeted information to IT professionals and a targeted audience to vendors. Our experience enables us to develop new online properties rapidly, and to acquire, and efficiently integrate, select properties that further serve IT professionals. We have also developed an expertise in implementing integrated, targeted marketing campaigns designed to maximize the measurability of, and improvement in, ROI.



•

Significant Brand Recognition Among Advertisers and IT Professionals.  Our brand is well-recognized by advertisers who value our integrated marketing capabilities and high-ROI advertising programs. At the same time, our sector-specific websites command brand recognition among IT professionals, who rely on these websites because of their specificity and depth of content.



•

Proprietary Lead Management Technology.  Our proprietary lead management technology enables IT vendors to prioritize and manage efficiently the leads we provide, improving the efficacy of their sales teams and optimizing the ROI on their marketing expenditures with us.

        Our solution increases efficiency for both IT professionals and IT vendors. It facilitates the ability of IT professionals to find specific information related to their purchase decisions, while enabling IT vendors

to reach IT buyers that are actively researching specific solutions related to vendors' products and services. Set forth below are several ways our solution benefits both IT professionals and IT vendors:

Benefits to IT Professionals

•

Provides Access to Integrated, Sector-Specific Content.  Our websites provide IT professionals with sector-specific content from the three fundamental sources they value in researching IT purchasing decisions: industry experts, peers and vendors. Our in-house staff of editors creates content specific to the sectors we serve and the key sub-sectors within them. This content is integrated with other content generated by our network of third-party industry experts, member-generated content and content from IT vendors.



•

Increases Efficiency of Purchasing Decisions.  By accessing targeted and specialized information, IT professionals are able to research important purchasing decisions more effectively. Furthermore, we provide this specialized, targeted content through a variety of media that together address all stages of the purchase decision process.

Benefits to IT Vendors

•

Targets Active Buyers Efficiently.  Our highly targeted content attracts specific, targeted audiences that are actively researching purchasing decisions. Advertising to only a targeted audience minimizes advertiser expenditures on irrelevant audiences, increasing advertising efficiency.



•

Generates Measurable, High ROI.  Our targeted online content offerings enable us to generate and collect valuable business information about each registered member and his or her technology preferences. As users access sponsored content, we register and process this information, and deliver qualified actionable leads in real-time. As a result, our advertisers are able to measure and improve the ROI on their advertising expenditures with us.



•

Generates and Prioritizes Qualified Sales Leads.  Our IT vendors also use our detailed member database and integrated advertising campaigns to identify and market to the audience members they consider to have the highest potential value. Once the leads have been delivered, our proprietary lead management technology enables customers to categorize, prioritize and market more effectively to these leads.



•

Maximizes Awareness and Shortens the Sales Cycle.  By distributing proprietary content and reaching their target audiences via our platform, IT vendors can educate audiences, demonstrate their product capabilities and proactively brand themselves as specific product leaders. As a result, an IT professional is knowledgeable about the vendors' specifications and product by the time he or she engages with the vendor, which reduces time and cost expended by the vendor's sales force.



•

Reaches IT Professionals at All Stages of the Purchase Decision Process.  Because our content platform encompasses online, event and print offerings, IT vendors can market to IT professionals at all stages of the purchase decision process through multiple touch points.

Our Strategy

        Our goal is to deliver superior performance by enhancing our position as a leading provider of specialized content that connects IT professionals with IT vendors in the sectors and sub-sectors that we serve. In order to achieve this goal, we intend to:

•

Continue to Develop Our Content Platform and Product Offerings.  We intend to continue to develop our platform in order to capitalize on the ongoing shift from traditional broad-based media toward more focused online content that increases the efficiency of advertising spending.

•

Expand into Complementary Sectors.  We intend to complement our current offerings by expanding our business to capitalize on strategic opportunities in existing, adjacent, or new sectors that we believe to be well-suited to our business model and core competencies. For example, we are expanding our platform to address the needs of additional sectors in the IT industry, such as value-added resellers and vertical industry software applications.



•

Expand Our International Presence.  We intend to expand our addressable market by increasing our presence in countries outside the United States.



•

Selectively Acquire or Partner with Complementary Businesses.  We intend to continue to pursue selected acquisition or partnership opportunities in our core markets and in adjacent markets for products with similar characteristics.

Recent Development

        On April 2,26, 2007, we entered into a letter of intent to acquireacquired for an aggregate purchase price of approximately $15.0 million substantially all of the assets of TechnologyGuide.com, Inc., a company engaged in the business of developing and operating a portfolio of proprietary Internet content sites that provide product reviews, price comparisons and user forums for certainmobile technology products.products such as laptops, PDAs, and tablet PCs. We may fundfunded this acquisition through existing cash balances orand by utilizing a portion of our existing revolving credit facility. We cannot assure you that we will acquire these assets or the final terms of this acquisition because the letter of intent is non-binding and is subject to: (i) the willingness of the current sellers to proceed with a transaction, (ii) our completion of satisfactory due diligence, (iii) the negotiation and execution of a mutually acceptable binding definitive purchase agreement, and (iv) the satisfaction of closing conditions.

Risk Factors

        Investing in our common stock involves a high degree of risk. You should carefully read the section entitled "Risk Factors" beginning on page 10 for an explanation of these risks before investing in our common stock. In particular, the following considerations, among others, may have a negative effect on our business, financial condition and results of operations:

•

Fluctuations in advertising spending could have an adverse effect on our operating results.



•

Because all of our customers are in the IT industry, our revenues are subject to many of the same fluctuations and risks associated with the IT industry, including exposure to corporate spending and increases in revenue concentration as a result of ongoing industry consolidation.



•

Our revenues are primarily derived from short-term contracts that may not be renewed.



•

If we are unable to deliver content and services that attract and retain users, our ability to attract and retain advertisers may be adversely affected.



•

Competition for advertisers is intense, and we may not compete successfully.

^(a)

In May 2004, we offered to repurchase for cash (i) up to 100% of the issued and outstanding shares of our series A preferred stock; and (ii) up to 45% of the aggregate issued and outstanding shares of common stock and/or options to purchase the same (provided the option holder had either completed four years of service with us as of May 1, 2004, or had held the option for at least four years as of May 1, 2004), effected to provide certain stockholders and option holders with liquidity. We recorded stock-based compensation expense of $6,012,382 related to the purchase of 5,716,6281,429,157 options.

Adjusted EBITDA is a metric used by management to measure operating performance. EBITDA represents net income (loss) before net interest expense, income tax expense, depreciation and amortization. Adjusted EBITDA represents EBITDA less stock-based compensation expense. We present Adjusted EBITDA as a supplemental performance measure because we believe it facilitates operating performance comparisons from period to period and company to company by backing out potential differences caused by variations in capital structures (affecting interest expense), tax positions (such as the impact on periods or companies of changes in effective tax rates or net operating losses), the age and book depreciation of fixed assets (affecting relative depreciation expense), and the impact of non-cash stock-based compensation expense costs. Because Adjusted EBITDA

facilitates internal comparisons of our operating performance on a more consistent basis, we also use Adjusted EBITDA in measuring our performance relative to that of our competitors. We also use Adjusted EBITDA in connection with our compensation of our executive officers. Adjusted EBITDA is not a measurement of our financial performance under generally accepted accounting principles in the United States, or GAAP, and should not be considered as an alternative to net income, operating income or any other performance measures derived in accordance with GAAP or as an alternative to cash flow from

operating activities as a measure of our profitability or liquidity. We understand that although Adjusted EBITDA is frequently used by securities analysts, lenders and others in their evaluation of companies, Adjusted EBITDA has limitations as an analytical tool, and you should not consider it in isolation, or as a substitute for analysis of our results as reported under GAAP. Some of these limitations are:

•

Adjusted EBITDA does not reflect our cash expenditures, or future requirements for capital expenditures or contractual commitments;



•

Adjusted EBITDA does not reflect changes in, or cash requirements for, our working capital needs;



•

Adjusted EBITDA does not reflect the significant interest expense, or the cash requirements necessary to service interest or principal payments, on our debts;



•

Although depreciation and amortization are non-cash charges, the assets being depreciated and amortized will often have to be replaced in the future, and Adjusted EBITDA does not reflect any cash requirements for such replacements; and



•

Other companies in our industry may calculate Adjusted EBITDA differently than we do, limiting its usefulness as a comparative measure.

        The pro forma balance sheet data in the table below reflects the conversion of our convertible preferred stock.stock and convertible preferred stock warrants. The pro forma as adjusted balance sheet data in the table below reflects the conversion of our convertible preferred stock and our receipt of estimated net proceeds from our sale of 6,427,152 shares of common stock in this offering at an assumed public offering price of $$13.00 per share, which is the midpoint of the range listed on the cover page of this prospectus, after deducting the estimated underwriting discounts and commissions and estimated offering expenses payable by us.

RISK FACTORS

        Investing in our common stock involves a high degree of risk. You should carefully consider the following risk factors, as well as the other information in this prospectus, before deciding whether to invest in our common stock. If any of the following risks were to materialize, our business, financial condition and results of operations would suffer. The trading price of our common stock could decline as a result of any of these risks, and you could lose part or all of your investment in our common stock. You should read the section entitled "Forward-Looking Statements" immediately following these risk factors for a discussion of what types of statements are forward-looking statements, as well as the significance of such statements in the context of this prospectus.

Risks Related to Our Business

Because we depend on our ability to generate revenues from the sale of advertising, fluctuations in advertising spending could have an adverse effect on our operating results.

        The primary source of our revenues is the sale of advertising to our customers. Our advertising revenues accounted for approximately 99% of our total revenues for the year ended December 31, 2006. We believe that advertising spending on the Internet, as in traditional media, fluctuates significantly as a result of a variety of factors, many of which are outside of our control. These factors include:

•

variations in expenditures by advertisers due to budgetary constraints;



•

the cancellation or delay of projects by advertisers;



•

the cyclical and discretionary nature of advertising spending;



•

general economic conditions, as well as economic conditions specific to the Internet and online and offline media industry; and



•

the occurrence of extraordinary events, such as natural disasters, international or domestic terrorist attacks or armed conflict.

Because all of our customers are in the IT industry, our revenues are subject to characteristics of the IT industry that can affect advertising spending by IT vendors.

        The IT industry is characterized by, among other things, volatile quarterly results, uneven sales patterns, short product life cycles, rapid technological developments and frequent new product introductions and enhancements. As a result, our customers' advertising budgets, which are often viewed as discretionary expenditures, may increase or decrease significantly over a short period of time. In addition, the advertising budgets of our customers may fluctuate as a result of:

•

weakness in corporate IT spending resulting in a decline in IT advertising spending;



•

increased concentration in the IT industry as a result of consolidations, leading to a decrease in the number of current and prospective customers, as well as an overall reduction in advertising spending by combined entities following such consolidations;



•

the timing of advertising campaigns around new product introductions and initiatives; and



•

economic conditions specific to the IT industry.

Our quarterly operating results are subject to significant fluctuations, and these fluctuations may adversely affect the trading price of our common stock.

        We have experienced and expect to experience significant fluctuations in our quarterly revenues and operating results. Our quarterly revenues and operating results may fluctuate significantly from quarter to quarter due to a number of factors, many of which are outside of our control. In addition to the factors described elsewhere in this "Risk Factors" section, these factors include:

•

the spending priorities and advertising budget cycles of specific advertisers;

•

the addition or loss of advertisers;



•

the addition of new sites and services by us or our competitors; and



•

seasonal fluctuations in advertising spending.

        Due to such risks, you should not rely on quarter-to-quarter comparisons of our results of operations as an indicator of our future results. Due to the foregoing factors, it is also possible that our results of operations in one or more quarters may fall below the expectations of investors and/or securities analysts. In such an event, the trading price of our common stock is likely to decline.

Our revenues are primarily derived from short-term contracts that may not be renewed.

        The primary source of our revenues is the sale of advertising to our customers, and we expect that this will continue to be the case for the foreseeable future. Our advertising contracts are almost exclusively short-term, typically less than 90 days, and are subject to termination without substantial penalty by the customer at any time, generally with minimal notice requirements of 30 days or less. We cannot assure you that our current customers will fulfill their obligations under their existing contracts, continue to participate in our existing programs beyond the terms of their existing contracts or enter into any additional contracts for new programs that we offer. If a significant number of advertisers or a few large advertisers decided not to continue advertising on our websites or in our print magazines, or conducting or sponsoring events, we could experience a rapid decline in our revenues over a relatively short period of time.

If we are unable to deliver content and services that attract and retain users, our ability to attract advertisers may be affected, which could in turn have an adverse affect on our revenues.

        Our future success depends on our ability to deliver original and compelling content and services to attract and retain users. Our user base is comprised of corporate IT professionals who demand specialized websites, print publications and events tailored to the sectors of the IT products for which they are responsible and that they purchase. Our content and services may not be attractive to a sufficient number of users to attract advertisers and generate revenues consistent with our estimates. We also may not develop new content or services in a timely or cost-effective manner. Our ability to develop and produce this specialized content successfully is subject to numerous uncertainties, including our ability to:

•

anticipate and respond successfully to rapidly changing IT developments and preferences to ensure that our content remains timely and interesting to our users;



•

attract and retain qualified editors, writers and technical personnel;



•

fund new development for our programs and other offerings;



•

successfully expand our content offerings into new platform and delivery mechanisms; and



•

promote and strengthen the brands of our websites and our name.

        If we are not successful in maintaining and growing our user base, our ability to retain and attract advertisers may be affected, which could in turn have an adverse affect on our revenues.

Our inability to sustain our historical advertising rates could adversely affect our operating results.

        The market for advertising has fluctuated over the past few years. If we are unable to maintain historical pricing levels for advertising on our websites and in our print publications and for sponsorships at our events, our revenues could be adversely affected.

Competition for advertisers is intense, and we may not compete successfully which could result in a material reduction in our market share, the number of our advertisers and our revenues.

        We compete for potential advertisers with a number of different types of offerings and companies, including: broad-based media outlets, such as television, newspapers and business periodicals that are designed to reach a wide audience; general purpose portals and search engines; and offline and online offerings of media companies that produce content specifically for IT professionals, including International Data Group, CMP Media Inc. and Ziff Davis Media Inc. Advertisers may choose our competitors over us not only because they prefer our competitors' online events and print offerings to ours, but also because advertisers prefer to utilize other forms of advertising offered by our competitors that are not offered by us.

        Although less than 5% of our revenues for the year ended December 31, 2006 were derived from advertisers located outside of North America, as we continue to expand internationally, we expect to compete with many of the competitors mentioned above, as well as with established media companies based in particular countries or geographical regions. Many of these foreign-based media companies will be larger than we are and will have established relationships with local advertisers.

        Many of our current and potential competitors have longer operating histories, larger customer bases, greater brand recognition and significantly greater financial, marketing and other resources than we have. As a result, we could lose market share to our competitors in one or more of our businesses and our revenues could decline.

We depend upon Internet search engines to attract a significant portion of the users who visit our websites, and if we were listed less prominently in search result listings, our business and operating results would be harmed.

        We derive a significant portion of our website traffic from users who search for IT purchasing content through Internet search engines, such as Google, MSN and Yahoo! A critical factor in attracting users to our websites is whether we are prominently displayed in response to an Internet search relating to IT content.

        Search result listings are determined and displayed in accordance with a set of formulas or algorithms developed by the particular Internet search engine. The algorithms determine the order of the listing of results in response to the user's Internet search. From time to time, search engines revise these algorithms. In some instances, these modifications may cause our websites to be listed less prominently in unpaid search results, which will result in decreased traffic from search engine users to our websites. Our websites may also become listed less prominently in unpaid search results for other reasons, such as search engine technical difficulties, search engine technical changes and changes we make to our websites. In addition, search engines have deemed the practices of some companies to be inconsistent with search engine guidelines and have decided not to list their websites in search result listings at all. If we are listed less prominently or not at all in search result listings for any reason, the traffic to our websites likely will decline, which could harm our operating results. If we decide to attempt to replace this traffic, we may be required to increase our marketing expenditures, which also could harm our operating results.

We may not innovate at a successful pace, which could harm our operating results.

        Our industry is rapidly adopting new technologies and standards to create and satisfy the demands of users and advertisers. It is critical that we continue to innovate by anticipating and adapting to these changes to ensure that our content-delivery platforms and services remain effective and interesting to our users, advertisers and partners. In addition, we may discover that we must make significant expenditures to achieve these goals. If we fail to accomplish these goals, we may lose users and the advertisers that seek to reach those users, which could harm our operating results.

We may be unable to continue to build awareness of our brands, which could negatively impact our business and cause our revenues to decline.

        Building and maintaining recognition of our brands is critical to attracting and expanding our online user base, attendance at our events and our offline readership. We intend to continue to build existing brands and introduce new brands that will resonate with our targeted audiences, but we may not be successful. In order to promote these brands, in response to competitive pressures or otherwise, we may find it necessary to increase our marketing budget, hire additional marketing and public relations personnel or otherwise increase our financial commitment to creating and maintaining brand loyalty among our clients. If we fail to promote and maintain our brands effectively, or incur excessive expenses attempting to promote and maintain our brands, our business and financial results may suffer.

Given the tenure and experience of our Chief Executive Officer and President, and their guiding roles in developing our business and growth strategy since our inception, our growth may be inhibited or our operations may be impaired if we were to lose the services of either of them.

        Our growth and success depends to a significant extent on our ability to retain Greg Strakosch, our Chief Executive Officer, and Don Hawk, our President, both of whom were founders of our company and have developed, engineered and stewarded the growth and operation of our business since its inception. The loss of the services of either of these persons could inhibit our growth or impair our operations and cause our stock price to decline.

We may not be able to attract, hire and retain qualified personnel cost-effectively, which could impact the quality of our content and services and the effectiveness and efficiency of our management, resulting in increased costs and losses in revenues.

        Our success depends on our ability to attract, hire and retain at commercially reasonable rates qualified technical, sales and marketing, customer support, financial and accounting, legal and other managerial personnel. The competition for personnel in the industries in which we operate is intense. Our personnel may terminate their employment at any time for any reason. Loss of personnel may also result in increased costs for replacement hiring and training. If we fail to attract and hire new personnel or retain and motivate our current personnel, we may not be able to operate our businesses effectively or efficiently, serve our customers properly or maintain the quality of our content and services.

        In particular, our success depends in significant part on maintaining and growing an effective sales force. This dependence involves a number of challenges, including:

•

the need to hire, integrate, motivate and retain additional sales and sales support personnel;



•

the need to train new sales personnel, many of whom lack sales experience when they are hired; and



•

competition from other companies in hiring and retaining sales personnel.

We may fail to identify or successfully acquire and integrate businesses, products and technologies that would otherwise enhance our product offerings to our customers and users, and as a result our revenues may decline or fail to grow.

        We have acquired, and in the future may acquire or invest in, complementary businesses, products or technologies. Furthermore, following the closing of this offering, we expect that as a result of our access to the public markets, we will have enhanced opportunities to pursue acquisitions and investments in the future. Acquisitions and investments involve numerous risks including:

•

difficulty in assimilating the operations and personnel of acquired businesses;



•

potential disruption of our ongoing businesses and distraction of our management and the management of acquired companies;



•

difficulty in incorporating acquired technology and rights into our offerings and services;

•

unanticipated expenses related to technology and other integration;

•

potential failure to achieve additional sales and enhance our customer bases through cross-marketing of the combined company's products to new and existing customers;



•

potential litigation resulting from our business combinations or acquisition activities; and



•

potential unknown liabilities associated with the acquired businesses.

        Our inability to integrate any acquired business successfully, or the failure to achieve any expected synergies, could result in increased expenses and a reduction in expected revenues or revenue growth. As a result, our stock price could fluctuate or decline. In addition, we cannot assure you that we will be successful in expanding into complementary sectors in the future, which could harm our business, operating results and financial condition.

The costs associated with potential acquisitions or strategic partnerships could dilute your investment or adversely affect our results of operations.

        In order to finance acquisitions, investments or strategic partnerships, we may use equity securities, debt, cash, or a combination of the foregoing. Any issuance of equity securities or securities convertible into equity may result in substantial dilution to our existing stockholders, reduce the market price of our common stock, or both. Any debt financing is likely to have financial and other covenants that could have an adverse impact on our business if we do not achieve our projected results. In addition, the related increases in expenses could adversely affect our results of operations.

We have limited protection of our intellectual property and could be subject to infringement claims that may result in costly litigation, the payment of damages or the need to revise the way we conduct our business.

        Our success and ability to compete are dependent in part on the strength of our proprietary rights, on the goodwill associated with our trademarks, trade names and service marks, and on our ability to use U.S. and foreign laws to protect them. Our intellectual property includes, among other things, our original content, our editorial features, logos, brands, domain names, the technology that we use to deliver our products and services, the various databases of information that we maintain and make available by license, and the appearance of our websites. We claim common law protection on certain names and marks that we have used in connection with our business activities. Although we have applied for and obtained registration of many of our marks in countries outside of the United States where we do business, we have not been able to obtain registration of all of our key marks in such jurisdictions, in some cases due to prior registration or use by third parties employing similar marks. In addition to U.S. and foreign laws, we rely on confidentiality agreements with our employees and third parties and protective contractual provisions to safeguard our intellectual property.

        Policing our intellectual property rights worldwide is a difficult task, and we may not be able to identify infringing users. We cannot be certain that third party licensees of our content will always take actions to protect the value of our proprietary rights and reputation. Intellectual property laws and our agreements may not be sufficient to prevent others from copying or otherwise obtaining and using our content or technologies. In addition, others may develop non-infringing technologies that are similar or superior to ours.

        In seeking to protect our marks, copyrights, domain names and other proprietary rights, or in defending ourselves against claims of infringement that may be with or without merit, we could face costly litigation and the diversion of our management's attention and resources. These claims could result in the need to develop alternative trademarks, content or technology or to enter into costly royalty or licensing agreements, which could have a material adverse effect on our business, results of operations and financial condition.

        We may not have, in all cases, conducted formal evaluations to confirm that our technology and products do not or will not infringe upon the intellectual property rights of third parties. As a result, we cannot be certain that our technology, offerings, services or online content do not or will not infringe upon

the intellectual property rights of third parties. If we were found to have infringed on a third party's intellectual property rights, the value of our brands and our business reputation could be impaired, and our business could suffer.

Our business could be harmed if we are unable to correspond with existing and potential users by e-mail.

        We use e-mail as a significant means of communicating with our existing users. The laws and regulations governing the use of e-mail for marketing purposes continue to evolve, and the growth and development of the market for commerce over the Internet may lead to the adoption of additional legislation and/or changes to existing laws. If new laws or regulations are adopted, or existing laws and regulations are interpreted and/or amended or modified, to impose additional restrictions on our ability to send e-mail to our users or potential users, we may not be able to communicate with them in a cost-effective manner.

        In addition to legal restrictions on the use of e-mail, Internet service providers and others typically attempt to block the transmission of unsolicited e-mail, commonly known as "spam." If an Internet service provider or software program identifies e-mail from us as "spam," we could be placed on a restricted list that would block our e-mail to users or potential users who maintain e-mail accounts with these Internet service providers or who use these software programs. If we are unable to communicate by e-mail with our users and potential users as a result of legislation, blockage or otherwise, our business, operating results and financial condition could be harmed.

Changes in laws and standards relating to data collection and use practices and the privacy of Internet users and other individuals could impair our efforts to maintain and grow our audience and thereby decrease our advertising revenue.

        We collect information from our users who register for services or respond to surveys. Subject to each user's permission (or right to decline, which we refer to as an "opt-out"), we may use this information to inform our users of products and services that may be of interest to them. We may also share this information with our advertising clients for registered members who have elected to receive additional promotional materials and have granted us permission to share their information with third parties. The U.S. federal and various state governments have adopted or proposed limitations on the collection, distribution and use of personal information of Internet users. Several foreign jurisdictions, including the European Union and Canada, have adopted legislation (including directives or regulations) that may limit our collection and use of information from Internet users in these jurisdictions. In addition, growing public concern about privacy, data security and the collection, distribution and use of personal information has led to self-regulation of these practices by the Internet advertising and direct marketing industry, and to increased federal and state regulation. Because many of the proposed laws or regulations are in their early stages, we cannot yet determine the impact these regulations may have on our business over time. Although, to date, our efforts to comply with applicable federal and state laws and regulations have not hurt our business, additional, more burdensome laws or regulations, including consumer privacy and data security laws, could be enacted or applied to us or our customers. Such laws or regulations could impair our ability to collect user information that helps us to provide more targeted advertising to our users, thereby impairing our ability to maintain and grow our audience and maximize advertising revenue from our advertising clients.

There are a number of risks associated with expansion of our business internationally that could adversely affect our business.

        We have 13 license arrangements in various countries and maintain a direct sales presence in the United Kingdom. In addition to facing many of the same challenges we face domestically, there are additional risks and costs inherent in expanding our business in international markets, including:

•

limitations on our activities in foreign countries where we have granted rights to existing business partners;



•

the adaptation of our websites and advertising programs to meet local needs and to comply with local legal regulatory requirements;



•

varied, unfamiliar and unclear legal and regulatory restrictions, as well as unforeseen changes in, legal and regulatory requirements;



•

more restrictive data protection regulation, which may vary by country;



•

difficulties in staffing and managing multinational operations;



•

difficulties in finding appropriate foreign licensees or joint venture partners;



•

distance, language and cultural differences in doing business with foreign entities;



•

foreign political and economic uncertainty;



•

less extensive adoption of the Internet as an information source and increased restriction on the content of websites;



•

currency exchange-rate fluctuations; and



•

potential adverse tax requirements.

        As a result, we may face difficulties and unforeseen expenses in expanding our business internationally and even if we attempt to do so, we may be unsuccessful, which could harm our business, operating results and financial condition.

Changes in regulations could adversely affect our business and results of operations.

        It is possible that new laws and regulations or new interpretations of existing laws and regulations in the United States and elsewhere will be adopted covering issues affecting our business, including:

•

privacy, data security and use of personally identifiable information;



•

copyrights, trademarks and domain names; and



•

marketing practices, such as e-mail or direct marketing.

        Increased government regulation, or the application of existing laws to online activities, could:

•

decrease the growth rate of the Internet;



•

reduce our revenues;



•

increase our operating expenses; or



•

expose us to significant liabilities.

        Furthermore, the relationship between regulations governing domain names and laws protecting trademarks and similar proprietary rights is still evolving. Therefore, we might be unable to prevent third parties from acquiring domain names that infringe or otherwise decrease the value of our trademarks and other proprietary rights. Any impairment in the value of these important assets could cause our stock price

to decline. We cannot be sure what effect any future material noncompliance by us with these laws and regulations or any material changes in these laws and regulations could have on our business, operating results and financial condition.

As a creator and a distributor of content over the Internet, we face potential liability for legal claims based on the nature and content of the materials that we create or distribute.

        Due to the nature of content published on our online network, including content placed on our online network by third parties, and as a creator and distributor of original content and research, we face potential liability based on a variety of theories, including defamation, negligence, copyright or trademark infringement, or other legal theories based on the nature, creation or distribution of this information. Such claims may also include, among others, claims that by providing hypertext links to websites operated by third parties, we are liable for wrongful actions by those third parties through these websites. Similar claims have been brought, and sometimes successfully asserted, against online services. It is also possible that our users could make claims against us for losses incurred in reliance on information provided on our networks. In addition, we could be exposed to liability in connection with material posted to our Internet sites by third parties. For example, many of our sites offer users an opportunity to post unmoderated comments and opinions. Some of this user-generated content may infringe on third party intellectual property rights or privacy rights or may otherwise be subject to challenge under copyright laws. Such claims, whether brought in the United States or abroad, could divert management time and attention away from our business and result in significant cost to investigate and defend, regardless of the merit of these claims. In addition, if we become subject to these types of claims and are not successful in our defense, we may be forced to pay substantial damages. Our insurance may not adequately protect us against these claims. The filing of these claims may also damage our reputation as a high quality provider of unbiased, timely analysis and result in client cancellations or overall decreased demand for our products and services.

We may be liable if third parties or our employees misappropriate our users' confidential business information.

        We currently retain confidential information relating to our users in secure database servers. Although we observe security measures throughout our operations, we cannot assure you that we will be able to prevent individuals from gaining unauthorized access to these database servers. Any unauthorized access to our servers, or abuse by our employees, could result in the theft of confidential user information. If confidential information is compromised, we could lose customers or become subject to liability or litigation and our reputation could be harmed, any of which could materially and adversely affect our business and results of operations.

Our business, which is dependent on centrally located communications and computer hardware systems, is vulnerable to natural disasters, telecommunication and systems failures, terrorism and other problems, which could reduce traffic on our networks or websites and result in decreased capacity for advertising space.

        Our operations are dependent on our communications systems and computer hardware, all of which are located in data centers operated by Verizon, Inc. These systems could be damaged by fire, floods, earthquakes, power loss, telecommunication failures and similar events. Our insurance policies have limited coverage levels for loss or damages in these events and may not adequately compensate us for any losses that may occur. In addition, terrorist acts or acts of war may cause harm to our employees or damage our facilities, our clients, our clients' customers and vendors, or cause us to postpone or cancel, or result in dramatically reduced attendance at, our events, which could adversely impact our revenues, costs and expenses and financial position. We are predominantly uninsured for losses and interruptions to our systems or cancellations of events caused by terrorist acts and acts of war.

Our systems may be subject to slower response times and system disruptions that could adversely affect our revenues.

        Our ability to attract and maintain relationships with users, advertisers and strategic partners will depend on the satisfactory performance, reliability and availability of our Internet infrastructure. Our Internet advertising revenues relate directly to the number of advertisements and other marketing opportunities delivered to our users. System interruptions or delays that result in the unavailability of

Internet sites or slower response times for users would reduce the number of advertising impressions and leads delivered. This could reduce our revenues as the attractiveness of our sites to users and advertisers decreases. Our insurance policies provide only limited coverage for service interruptions and may not adequately compensate us for any losses that may occur due to any failures or interruptions in our systems. Further, we do not have multiple site capacity for all of our services in the event of any such occurrence. We may experience service disruptions for the following reasons:

•

occasional scheduled maintenance;



•

equipment failure;



•

volumes of visits to our websites that exceed our infrastructure's capacity; and



•

natural disasters, telecommunications failures, power failures, other system failures, maintenance, viruses, hacking or other events.

        In addition, our networks and websites must accommodate a high volume of traffic and deliver frequently updated information. They have experienced in the past, and may experience in the future, slower response times or decreased traffic for a variety of reasons. There have been instances where our online networks as a whole, or our websites individually, have been inaccessible. Also, slower response times, which have occurred more frequently, can result from general Internet problems, routing and equipment problems involving third party Internet access providers, problems with third party advertising servers, increased traffic to our servers, viruses and other security breaches, many of which problems are out of our control. In addition, our users depend on Internet service providers and online service providers for access to our online networks or websites. Those providers have experienced outages and delays in the past, and may experience outages or delays in the future. Moreover, our Internet infrastructure might not be able to support continued growth of our online networks or websites. Any of these problems could result in less traffic to our networks or websites or harm the perception of our networks or websites as reliable sources of information. Less traffic on our networks and websites or periodic interruptions in service could have the effect of reducing demand for advertising on our networks or websites, thereby reducing our advertising revenues.

Our networks may be vulnerable to unauthorized persons accessing our systems, viruses and other disruptions, which could result in the theft of our proprietary information and/or disrupt our Internet operations making our websites less attractive and reliable for our users and advertisers.

        Internet usage could decline if any well-publicized compromise of security occurs. "Hacking" involves efforts to gain unauthorized access to information or systems or to cause intentional malfunctions or loss or corruption of data, software, hardware or other computer equipment. Hackers, if successful, could misappropriate proprietary information or cause disruptions in our service. We may be required to expend capital and other resources to protect our websites against hackers.

        Our online networks could also be affected by computer viruses or other similar disruptive problems, and we could inadvertently transmit viruses across our networks to our users or other third parties. Any of these occurrences could harm our business or give rise to a cause of action against us. Providing unimpeded access to our online networks is critical to servicing our customers and providing superior customer service. Our inability to provide continuous access to our online networks could cause some of

our customers to discontinue purchasing advertising programs and services and/or prevent or deter our users from accessing our networks.

        Our activities and the activities of third party contractors involve the storage and transmission of proprietary and personal information. Accordingly, security breaches could expose us to a risk of loss or litigation and possible liability. We cannot assure that contractual provisions attempting to limit our liability in these areas will be successful or enforceable, or that other parties will accept such contractual provisions as part of our agreements.

We have never operated as a public company.

        As a public company, we will incur significant legal, accounting and other expenses that we did not incur as a private company. In addition, the Sarbanes-Oxley Act of 2002 and rules subsequently implemented by the SEC and the NASDAQ Global Market have imposed various requirements on public companies, including requiring changes in corporate governance practices. Our management and other personnel will need to devote a substantial amount of time to these compliance initiatives. Moreover, these rules and regulations will increase our legal and financial compliance costs and will make some activities more time-consuming and costly.

If we fail to maintain proper and effective disclosure controls and procedures and internal controls over financial reporting, our ability to produce accurate financial statements could be impaired, which could adversely affect our operating results, our ability to operate our business and investors' views of us.

        Ensuring that we have adequate disclosure controls and procedures, including internal financial and accounting controls and procedures, in place to help ensure that we can produce accurate financial statements on a timely basis is a costly and time-consuming effort that needs to be re-evaluated frequently. We are in the process of documenting, reviewing and, if appropriate, improving our internal controls and procedures in connection with the requirements of Section 404 of the Sarbanes-Oxley Act, which requires annual management assessments of the effectiveness of our internal controls over financial reporting and a report by our independent auditors addressing these assessments. Both we and our independent auditors will be testing our internal controls in connection with the Section 404 requirements and, as part of that documentation and testing, identifying areas for further attention and improvement. Implementing any appropriate changes to our internal controls may entail substantial costs in order to modify our existing accounting systems, take a significant period of time to complete and distract our officers, directors and employees from the operation of our business. These changes may not, however, be effective in maintaining the adequacy of our internal controls, and any failure to maintain that adequacy, or consequent inability to produce accurate financial statements on a timely basis, could increase our operating costs and could materially impair our ability to operate our business. In addition, investors' perceptions that our internal controls are inadequate or that we are unable to produce accurate financial statements may seriously affect our stock price.

Our ability to raise capital in the future may be limited.

        Our business and operations may consume resources faster than we anticipate. In the future, we may need to raise additional funds to expand our sales and marketing and product development efforts or to make acquisitions. Additional financing may not be available on favorable terms, if at all. If adequate funds are not available on acceptable terms, we may be unable to fund the expansion of our sales and marketing and research and development efforts or take advantage of acquisition or other opportunities, which could seriously harm our business and operating results. If we incur debt, the debt holders would have rights senior to common stockholders to make claims on our assets and the terms of any debt could restrict our operations, including our ability to pay dividends on our common stock. Furthermore, if we issue additional equity securities, stockholders will experience dilution, and the new equity securities could have rights senior to those of our common stock. Because our decision to issue securities in any future offering

will depend on market conditions and other factors beyond our control, we cannot predict or estimate the amount, timing or nature of our future offerings. Thus, our stockholders bear the risk of our future securities offerings reducing the market price of our common stock and diluting their interest.

The impairment of a significant amount of goodwill and intangible assets on our balance sheet could result in a decrease in earnings and, as a result, our stock price could decline.

        In the course of our operating history, we have acquired assets and businesses. Some of our acquisitions have resulted in the recording of a significant amount of goodwill and/or intangible assets on our financial statements. We had $42$43 million of goodwill and net intangible assets as of DecemberMarch 31, 2006. 2007.

The goodwill and/or intangible assets were recorded because the fair value of the net tangible assets acquired was less than the purchase price. We may not realize the full value of the goodwill and/or intangible assets. As such, we evaluate goodwill and other intangible assets with indefinite useful lives for impairment on an annual basis or more frequently if events or circumstances suggest that the asset may be impaired. We evaluate other intangible assets subject to amortization whenever events or changes in circumstances indicate that the carrying amount of those assets may not be recoverable. If goodwill or other intangible assets are determined to be impaired, we will write off the unrecoverable portion as a charge to our earnings. If we acquire new assets and businesses in the future, as we intend to do, we may record additional goodwill and/or intangible assets. The possible write-off of the goodwill and/or intangible assets could negatively impact our future earnings and, as a result, the market price of our common stock could decline.

We will record substantial expenses related to our issuance of stock-based compensation which may have a material negative impact on our operating results for the foreseeable future.

        Effective January 1, 2006, we adopted the Statement of Financial Accounting Standards, or SFAS, No. 123(R),Accounting for Stock-Based Compensation, as amended by SFAS No. 148,Accounting for Stock-Based Compensation—Transition and Disclosure for stock-based employee compensation. Our stock-based compensation expenses are expected to be significant in future periods, which will have an adverse impact on our operating income and net income. SFAS No. 123(R) requires the use of highly subjective assumptions, including the option's expected life and the price volatility of the underlying stock. Changes in the subjective input assumptions can materially affect the amount of our stock-based compensation expense. In addition, an increase in the competitiveness of the market for qualified employees could result in an increased use of stock-based compensation awards, which in turn would result in increased stock-based compensation expense in future periods.

Risks Related to This Offering and Ownership of Our Common Stock

No public market for our common stock currently exists, and an active, liquid and orderly market for our common stock may not develop.

        Prior to this offering there has been no market for shares of our common stock. Even though we have applied to list our shares on the NASDAQ Global Market, an active trading market for our common stock may never develop or be sustained, which could depress the market price of our common stock and could affect your ability to sell your shares. The initial public offering price will be determined through conversations with us and the representatives of the underwriters and may bear no relationship to the price at which our common stock will trade following the completion of this offering.

The trading value of our common stock may be volatile and decline substantially.

        The trading price of our common stock following this offering is likely to be volatile and could be subject to wide fluctuations in response to various factors, some of which are beyond our control. In

addition to the factors discussed in this "Risk Factors" section and elsewhere in this prospectus, these factors include:

•

our operating performance and the operating performance of similar companies;



•

the overall performance of the equity markets;



•

announcements by us or our competitors of acquisitions, business plans or commercial relationships;



•

threatened or actual litigation;



•

changes in laws or regulations relating to the provision of Internet content;



•

any major change in our board of directors or management;

•

publication of research reports about us, our competitors or our industry, or positive or negative recommendations or withdrawal of research coverage by securities analysts;



•

our sale of common stock or other securities in the future;



•

large volumes of sales of our shares of common stock by existing stockholders; and



•

general political and economic conditions.

        In addition, the stock market in general, and historically the market for Internet-related companies in particular, has experienced extreme price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of those companies. These fluctuations may be even more pronounced in the trading market for our stock shortly following this offering. Securities class action litigation has often been instituted against companies following periods of volatility in the overall market and in the market price of a company's securities. This litigation, if instituted against us, could result in substantial costs, divert our management's attention and resources and harm our business, operating results and financial condition.

Provisions of our certificate of incorporation, bylaws and Delaware law could deter takeover attempts.

        Various provisions in our certificate of incorporation and bylaws could delay, prevent or make more difficult a merger, tender offer, proxy contest or change of control. Our stockholders might view any transaction of this type as being in their best interest since the transaction could result in a higher stock price than the then-current market price for our common stock. Among other things, our certificate of incorporation and bylaws:

•

authorize our board of directors to issue preferred stock with the terms of each series to be fixed by our board of directors, which could be used to institute a "poison pill" that would work to dilute the share ownership of a potential hostile acquirer, effectively preventing acquisitions that have not been approved by our board;



•

divide our board of directors into three classes so that only approximately one-third of the total number of directors is elected each year;



•

permit directors to be removed only for cause;



•

prohibit action by less than unanimous written consent of our stockholders; and



•

specify advance notice requirements for stockholder proposals and director nominations.

        In addition, with some exceptions, the Delaware General Corporation Law restricts or delays mergers and other business combinations between us and any stockholder that acquires 15% or more of our voting stock.

Future sales of shares of our common stock by existing stockholders could depress the market price of our common stock.

        If our existing stockholders sell, or indicate an intent to sell, substantial amounts of our common stock in the public market after the 180-day contractual lock-up and other legal restrictions on resale discussed in this prospectus lapse, the trading price of our common stock could decline significantly and could decline below the initial public offering price. Based on shares outstanding as of DecemberMarch 31, 2006,2007, upon completion of this offering, we will have outstanding approximately 39,059,535 shares of common stock, assuming no exercise of the underwriters' over-allotment option. Morgan Stanley & Co. Incorporated and Lehman Brothers Inc. may, in their sole discretion, permit our officers, directors, employees and current stockholders to sell shares prior to the expiration of the lock-up agreements.

        After the lock-up agreements pertaining to this offering expire, and based on shares outstanding as of DecemberMarch 31, 2006,2007, an additional 30,894,493 shares will be eligible for sale in the public market, 24,123,156 of which are held by directors, executive officers and other affiliates and will be subject to volume limitations

under Rule 144 under the Securities Act of 1933, as amended, or the Securities Act, and various vesting agreements. In addition, the 31,689,2917,612,910 shares subject to outstanding options under our 1999 Stock Option Plan as of DecemberMarch 31, 2006 and2007, the 2,911,667 shares reserved for future issuance under our 2007 Stock Option and Incentive Plan and 73,003 shares issuable upon exercise of warrants will become eligible for sale in the public market in the future, subject to certain legal and contractual limitations. See "Shares Eligible for Future Sale" for a more detailed description of sales that may occur in the future. If these additional shares are sold, or if it is perceived that they will be sold, in the public market, the trading price of our common stock could decline substantially.

A limited number of stockholders will have the ability to influence the outcome of director elections and other matters requiring stockholder approval.

        Immediately after this offering, our directors, executive officers and their affiliated entities will beneficially own more than72.4% percent of our outstanding common stock.stock, or 77.3% assuming the TCV Funds purchase $25 million of our common stock at the midpoint of the range listed on the cover of this prospectus. These stockholders, if they act together, could exert substantial influence over matters requiring approval by our stockholders, including the election of directors, the amendment of our certificate of incorporation and bylaws and the approval of mergers or other business combination transactions. This concentration of ownership may discourage, delay or prevent a change in control of our company, which could deprive our stockholders of an opportunity to receive a premium for their stock as part of a sale of our company and might reduce our stock price. These actions may be taken even if they are opposed by other stockholders, including those who purchase shares in this offering.

Our management will have broad discretion over the use of the proceeds we receive in this offering and might not apply the proceeds in ways that increase the value of your investment.

        Our management will have broad discretion to use the net proceeds from this offering, and you will be relying on the judgment of our management regarding the application of these proceeds. Our management might not apply the net proceeds of this offering in ways that increase the value of your investment. We intend to use the net proceeds to us from this offering for repayment of $12.0 million under our revolving credit facility, working capital and other general corporate purposes including(including financing the development of new offerings,offerings), sales and marketing activities, and capital expenditures. We may use a portion of the net proceeds to us to expand our current business through acquisitions of other businesses, products and technologies. Until we use the net proceeds from this offering, we plan to invest them, and these investments may not yield a favorable rate of return. If we do not invest or apply the net proceeds from this offering in ways that enhance stockholder value, we may fail to achieve expected financial results, which could cause our stock price to decline.

You will experience immediate and substantial dilution.

        The initial public offering price will be substantially higher than the net tangible book value of each outstanding share of common stock immediately after this offering.

FORWARD-LOOKING STATEMENTS

        This prospectus contains forward-looking statements. All statements other than statements of historical facts contained in this prospectus, including statements regarding our future results of operations and financial position, business strategy and plans and objectives of management for future operations, are forward-looking statements. These statements involve known and unknown risks, uncertainties and other factors that may cause our actual results, performance or achievements to be materially different from any future results, performance or achievements expressed or implied by the forward-looking statements.

        In some cases, you can identify forward-looking statements by terms such as "may," "might," "will," "should," "expects," "plans," "anticipates," "could," "intends," "target," "projects," "contemplates," "believes," "estimates," "predicts," "potential" or "continue" or the negative of these terms or other similar words. These statements are only predictions. We have based these forward-looking statements largely on our current expectations and projections about future events and financial trends that we believe may affect our business, financial condition and results of operations. We discuss many of the risks in greater detail under the heading "Risk Factors." Also, these forward-looking statements represent our estimates and assumptions only as of the date of this prospectus. Except as required by law, we assume no obligation to update any forward-looking statements after the date of this prospectus.

        This prospectus also contains estimates and other statistical data made by independent parties and by us relating to market size and growth and other industry data. This data involves a number of assumptions and limitations, and you are cautioned not to give undue weight to such estimates. We have not independently verified the statistical and other industry data generated by independent parties and contained in this prospectus and, accordingly, we cannot guarantee their accuracy or completeness. In addition, projections, assumptions and estimates of our future performance and the future performance of the industries in which we operate are necessarily subject to a high degree of uncertainty and risk due to a variety of factors, including those described in "Risk Factors," "Management's Discussion and Analysis of Financial Condition and Results of Operations" and elsewhere in this prospectus. These and other factors could cause results to differ materially from those expressed in the estimates made by the independent parties and by us.

USE OF PROCEEDS

        We estimate that the net proceeds to us of the sale of the common stock that we are offering will be approximately $$75.2 million, based on an assumed initial public offering price of $$13.00 per share, which is the midpoint of the range listed on the cover page of this prospectus, after deducting the estimated underwriting discounts and commissions and estimated offering expenses that we must pay. The selling stockholders will receive aggregate net proceeds of approximately $15.4 million after deducting the estimated underwriting discounts and commissions. We will not receive any proceeds from the sale of shares of common stock by the selling stockholders. Our Chief Executive Officer and other members of our senior management will receive a portion of the proceeds of this offering if the underwriters exercise their over-allotment option. See "Principal and Selling Stockholders." A $1.00 increase (decrease) in the assumed initial public offering price of $$13.00 per share would increase (decrease) the net proceeds to us from this offering by $approximately $6.0 million, assuming the number of shares offered by us, as set forth on the cover of this prospectus, remains the same and after deducting the estimated underwriting discounts and commissions and estimated offering expenses payable by us.

        We intend to use the net proceeds to us from this offering primarily according to the following priority of use: repayment of $12.0 million under our revolving credit facility, working capital and other general corporate purposes (including financing the development of new offerings), sales and marketing activities, and capital expenditures. We may use a portion of the net proceeds to us to expand our current business through acquisitions of other businesses, products and technologies. In view of our existing cash balances and availability of our existing revolving line of credit, a substantial reduction in the amount of proceeds from the amount shown above would not have a significant effect upon our planned expenditures.

        The portion of our net proceeds that will be used to repay existing indebtedness will be approximately $12.0 million to repay aggregate principal and interest under our revolving credit facility with Citizens Bank. At our option, the revolving credit facility bears interest at either the lender's prime rate less 1.00% or the London Interbank Offered Rate, or LIBOR, plus 1.50%. Our revolving credit facility matures on August 30, 2011. We borrowed against our revolving credit facility to partially fund the acquisition of TechnologyGuide.com, Inc.

        Pending any use, as described above, we plan to invest the net proceeds in investment-grade, interest-bearing securities.

DIVIDEND POLICY

        We have never declared or paid any cash dividends on our capital stock and do not have any plans to pay any cash dividends for the foreseeable future. We intend to use future earnings, if any, in the operation and expansion of our business. In addition, the terms of our credit facility restrict our ability to pay dividends, and any future indebtedness that we may incur could preclude us from paying dividends.

CAPITALIZATION

        The following table sets forth our capitalization as of DecemberMarch 31, 2006:2007:

•

on an actual basis; and



•

on a pro forma as adjusted basis to give effect to the conversion of our convertible preferred stock into shares of common stock and convertible preferred stock warrants listed within other liabilities into common stock warrants listed within stockholders' equity (deficit) and to reflect the sale of 6,427,152 shares of common stock that we are offering at an assumed initial public offering price of $$13.00 per share, which is the midpoint of the range listed on the cover page of this prospectus, after deducting the estimated underwriting discounts and commissions and estimated offering expenses payable by us.

        You should read the following table in conjunction with our consolidated financial statements and related notes and the sections entitled "Selected Consolidated Financial Data" and "Management's Discussion and Analysis of Financial Condition and Results of Operations" appearing elsewhere in this prospectus.

⁽¹⁾

The CompanyWe applied the guidance included in EITF Topic No. D-98,Classification and Measurement of Redeemable Securities, to conclude our redeemable convertible preferred stock should be classified outside of permanent equity. The 97,491,861 shares of our redeemable convertible preferred stock will convert into 97,491,86124,372,954 shares of common stock upon the closing of this offering.

⁽²⁾

A $1.00 increase (decrease) in the assumed initial public offering price of $$13.00 per share would increase (decrease) each of cash and cash equivalents, additional paid-in capital, total stockholders' equity and total capitalization by $approximately $6.0 million, assuming the number of shares offered by us, as set forth on the cover of this prospectus, remains the same and after deducting the estimated underwriting discounts and commissions and estimated offering expenses payable by us.

DILUTION

        Our pro forma net tangible book value as of DecemberMarch 31, 20062007 was $29.3$30.8 million or $0.23$0.94 per share of common stock. Pro forma net tangible book value per share represents the amount of our pro forma total tangible assets less our pro forma total liabilities, divided by the number of shares of common stock outstanding as of DecemberMarch 31, 20062007 after giving effect to the assumed conversion of all of our convertible preferred stock.

        After giving effect to the sale by us of 6,427,152 shares of common stock in this offering at the assumed initial public offering price of $$13.00 per share, which is the midpoint of the range listed on the cover page of this prospectus, and after deducting the estimated underwriting discounts and commissions and estimated offering expenses payable by us, our adjusted net tangible book value as of DecemberMarch 31, 20062007 would have been approximately $$106.0 million, or approximately $$2.71 per share. This amount represents an immediate increase in net tangible book value of $$1.77 per share to our existing stockholders and an immediate dilution in net tangible book value of approximately $$10.29 per share to new investors purchasing shares of common stock in this offering at the assumed initial public offering price. We determine dilution by subtracting the adjusted net tangible book value per share after this offering from the amount of cash that a new investor paid for a share of common stock.

        The following table illustrates this dilution on a per share basis:

        A $1.00 increase (decrease) in the assumed initial public offering price of $$13.00 would increase (decrease) our pro forma as adjusted net tangible book value per share after this offering by $$0.15 per share and the dilution in pro forma net tangible book value to new investors by $$0.15 per share, assuming the number of shares offered by us, as set forth on the cover of this prospectus, remains the same and after deducting the estimated underwriting discounts and commissions and estimated offering expenses payable by us.

        The following table summarizes, as of DecemberMarch 31, 2006,2007, the differences between the number of shares purchased from us, the total consideration paid to us in cash and the average price per share that existing stockholders and new investors paid. The following table does not reflect any non-cash consideration paid to us, or deemed to be paid to us, by our existing stockholders. The calculation below is based on the assumed initial public offering price of $$13.00 per share, which is the midpoint of the range listed on the cover page of this prospectus, before deducting the estimated underwriting discounts and commissions and estimated offering expenses that we must pay:

(1)

Assumes conversion of all outstanding shares of preferred stock.

        A $1.00 increase (decrease) in the assumed initial public offering price of $$13.00 would increase (decrease) total consideration paid by new investors, total consideration paid by all stockholders and the average price paid by all stockholders by $$6.4 million, $$6.4 million, and $            ,$0.16, respectively, assuming the number of shares offered by us, as set forth on the cover of this prospectus, remains the same, and without deducting the estimated underwriting discounts and commissions and other expenses of the offering.

        The above discussion and tables assumes no exercise of outstanding options or outstanding warrants after DecemberMarch 31, 2006.2007. As of DecemberMarch 31, 2006,2007, we had outstanding options to purchase a total of 31,689,2907,612,910 shares of common stock at a weighted average exercise price of $1.24$5.13 per share, and outstanding warrants to purchase a total of 292,01773,003 shares of common stock at a weighted average exercise price of $0.57$2.27 per share. To the extent any of these options or warrants are exercised, there will be further dilution to new investors.
