	1. Organization and Operations
	TechTarget, Inc. (the “Company”) is a leading provider of specialized online content and brand advertising that brings together buyers and sellers of corporate information technology (“IT”) products. The Company sells customized marketing programs that enable IT vendors to reach corporate IT decision makers who are actively researching specific IT purchases. The Company operates a network of over 150 websites, each of which focuses on a specific IT sector, such as storage, security or networking. During the critical stages of the purchase decision process, these content offerings meet IT professionals’ needs for expert, peer and IT vendor information, and provide a platform on which IT vendors can launch targeted marketing campaigns which generate measurable, high return on investment (“ROI”). As IT professionals have become increasingly specialized, they have come to rely on the Company’s sector-specific websites for purchasing decision support. The Company’s content enables IT professionals to navigate the complex and rapidly changing IT landscape where purchasing decisions can have significant financial and operational consequences. Based upon the logical clustering of users’ respective job responsibilities and the marketing focus of the products that the Company’s customers are advertising, content offerings are currently categorized across nine distinct media groups: Application Architecture and Development; Channel; CIO/IT Strategy; Data Center and Virtualization Technologies; Business Applications and Analytics; Networking; Security; Storage; and TechnologyGuide.

Summary of Significant Accounting Policies	'
	2. Summary of Significant Accounting Policies
	The accompanying consolidated financial statements reflect the application of certain significant accounting policies as described below and elsewhere in these Notes to Consolidated Financial Statements.
	Principles of Consolidation
	The accompanying Consolidated Financial Statements include the accounts of the Company and its wholly-owned subsidiaries, which are comprised of KnowledgeStorm, Inc., Bitpipe, Inc., TechTarget Securities Corporation (“TSC”), TechTarget Limited, TechTarget (HK) Limited, TechTarget (Beijing) Information Technology Consulting Co., Ltd., TechTarget (Australia) Pty Ltd., TechTarget (Singapore) Pte Ltd. and E-Magine Médias SAS. KnowledgeStorm, Inc. and Bitpipe, Inc. feature websites that provide in-depth vendor generated content targeted to corporate IT professionals. TechTarget Securities Corporation is a Massachusetts security corporation incorporated in 2004. TechTarget Limited is a subsidiary doing business principally in the United Kingdom. TechTarget (HK) Limited (“TTGT HK”) is a subsidiary incorporated in Hong Kong in order to facilitate the Company’s activities in the Asia-Pacific region. Additionally, through its wholly-owned subsidiaries, TTGT HK and TechTarget (Beijing) Information Technology Consulting Co., Ltd. (“TTGT Consulting”, incorporated on December 16, 2011), the Company effectively controls a variable interest entity (“VIE”), Keji Wangtuo Information Technology Co., Ltd., (“KWIT”), which was incorporated under the laws of the People’s Republic of China (“PRC”) on November 27, 2007. TechTarget (Australia) Pty Ltd. (incorporated on December 15, 2011) and TechTarget (Singapore) Pte Ltd. (incorporated on February 12, 2012) are the entities through which the Company does business in Australia and Singapore, respectively and E-Magine Médias SAS (“LeMagIT”), a wholly-owned subsidiary of TechTarget Limited, is an entity through which the Company does business in France.
	PRC laws and regulations prohibit or restrict foreign ownership of Internet-related services and advertising businesses. To comply with these foreign ownership restrictions, the Company operates its websites and provides online advertising services in the PRC through KWIT. The Company entered into certain exclusive agreements with KWIT and its shareholders through TTGT HK, which obligated TTGT HK to absorb all of the risk of loss from KWIT’s activities and entitled TTGT HK to receive all of their residual returns. In addition, the Company entered into certain agreements with the authorized parties through TTGT HK, including Management and Consulting Services, Voting Proxy, Equity Pledge and Option Agreements. On December 31, 2011, TTGT HK assigned all of its rights and obligations to the newly formed wholly foreign-owned enterprise (“WFOE”), TTGT Consulting. The WFOE is established and existing under the laws of the PRC, and is wholly owned by TTGT HK.
	Based on these contractual arrangements, the Company consolidates the financial results of KWIT as required by Accounting Standards Codification (“ASC”) subtopic 810-10 (“ASC 810-10”), Consolidation: Overall, because the Company holds all the variable interests of KWIT through the WFOE, which is the primary beneficiary of KWIT. Despite the lack of technical majority ownership, there exists a parent-subsidiary relationship between the Company and the VIE through the aforementioned agreements, whereby the equity holders of KWIT assigned all of their voting rights underlying their equity interest in KWIT to the WFOE. In addition, through the other aforementioned agreements, the Company demonstrates its ability and intention to continue to exercise the ability to obtain substantially all of the profits and absorb all of the expected losses of KWIT. All significant intercompany accounts and transactions between the Company, its subsidiaries, and KWIT have been eliminated in consolidation.
	Use of Estimates
	The preparation of financial statements in conformity with Generally Accepted Accounting Principles (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. On an ongoing basis, the Company evaluates its estimates, including those related to revenue, long-lived assets, goodwill, the allowance for doubtful accounts, stock-based compensation, earnouts, self-insurance accruals and income taxes. Estimates of the carrying value of certain assets and liabilities are based on historical experience and on various other assumptions that the Company believes to be reasonable. Actual results could differ from those estimates.
	Revenue Recognition
	The Company generates substantially all of its revenue from the sale of targeted advertising campaigns, which are delivered via its network of websites, and events. Revenue is recognized only when the price is fixed or determinable, persuasive evidence of an arrangement exists, the service is performed and collectability of the resulting receivable is reasonably assured.
	The majority of the Company’s online media sales involve multiple product offerings, which are described in more detail below. Because neither vendor-specific objective evidence of fair value nor third party evidence of fair value exists for all elements in the Company’s bundled product offerings, the Company uses an estimated selling price which represents management’s best estimate of the stand-alone selling price for each deliverable in an arrangement. The Company establishes best estimates considering multiple factors including, but not limited to, class of client, size of transaction, available media inventory, pricing strategies and market conditions. The Company believes the use of the best estimate of selling price allows revenue recognition in a manner consistent with the underlying economics of the transaction. The Company uses the relative selling price method to allocate consideration at the inception of the arrangement to each deliverable in a multiple element arrangement. The relative selling price method allocates any discount in the arrangement proportionately to each deliverable on the basis of the deliverable’s best estimated selling price. Revenue is then recognized as delivery occurs.
	The Company evaluates all deliverables of an arrangement at inception and each time an item is delivered, to determine whether they represent separate units of accounting. Based on this evaluation, the arrangement consideration is measured and allocated to each of these elements.

	Online Media. Revenue for lead generation campaigns is recognized as follows:
	Beginning in the period ended March 31, 2012, the Company’s lead generation campaigns all offer the Activity Intelligence™ Dashboard (the “Dashboard”). In order to manage the lead generation component, the Company changed its operational approach and the contractual terms and conditions under which it sells its products. Instead of contracting to sell individual elements, the Company sells various lead generation campaigns with the Dashboard. Accordingly, for duration-based campaigns, revenue is recognized ratably over the duration of the campaigns, which is usually less than six months. Lead generation offerings may also include an additional service, Nurture & Qualify (formerly called Nurture & Notify), in which case revenue is recognized ratably over the period of the campaign as a combined unit of accounting. As part of these lead generation campaign offerings, the Company will guarantee a minimum number of qualified leads to be delivered over the course of the advertising campaign. The Company determines the content necessary to achieve performance guarantees. Scheduled end dates of advertising campaigns sometimes need to be extended, pursuant to the terms of the arrangement, to satisfy lead guarantees. The Company estimates a revenue reserve necessary to adjust revenue recognition for extended advertising campaigns. These estimates are based on the Company’s experience in managing and fulfilling these offerings. The customer has cancellation privileges which generally require advance notice by the customer and require proportional payment by the customer for the portion of the campaign period provided by the Company. Additionally, the Company offers sales incentives to certain customers, primarily in the form of volume rebates, which are classified as a reduction of revenues and are calculated based on the terms of the specific customer’s contract. The Company accrues for these sales incentives based on contractual terms and historical experience.
	The Company recognizes revenue on contracts where pricing is based on cost per lead in the period during which the leads are delivered to its customers.
	Revenue for other significant online media offerings is recognized as follows:

		•		Custom Content Creation. Custom content revenue is recognized when the creation is completed and delivered to the customer, with the exception of microsites which are recognized over the period during which they are live.

		•		Content Sponsorships. Content sponsorship revenue is recognized ratably over the period in which the related content asset is available on the Company’s websites.

		•		List Rentals and IT Deal Alert™. List rental and IT Deal Alert revenue is recognized in the period in which the delivery of the report is made to the Company’s customer.

		•		Banners. Banner revenue is recognized in the period in which the banner impressions or clicks occur.

		•		Third Party Revenue Sharing Arrangements. Revenue from third party revenue sharing arrangements is recognized on a net basis in the period in which the services are performed. For certain third party agreements where the Company is the primary obligor, revenue is recognized on a gross basis in the period in which the services are performed.

		•		In 2011, revenue for elements of lead generation campaigns was recognized as follows:

		•		White Papers. White paper revenue was recognized ratably over the period in which the white paper was available on the Company’s websites.

		•		Webcasts, Podcasts, Videocasts and Virtual Trade Shows. Webcast, podcast, videocast, virtual trade show and similar content revenue was recognized ratably over the period in which the webcast, podcast, videocast or virtual trade show was available on the Company’s websites.
	Event Sponsorships. Revenue from vendor-sponsored events, whether sponsored exclusively by a single vendor or in a multi-vendor sponsored event, is recognized upon completion of the event in the period the event occurs. The majority of the Company’s events are free to qualified attendees; however, certain events are based on a paid attendee model. The Company recognizes revenue for paid attendee events upon completion of the event.

	Amounts collected or billed prior to satisfying the above revenue recognition criteria are recorded as deferred revenue. The Company excludes from its deferred revenue and accounts receivable balances amounts for which it has billed in advance prior to the start of a campaign or the delivery of services.
	Fair Value of Financial Instruments
	Financial instruments consist of cash and cash equivalents, short and long-term investments, accounts receivable, accounts payable and contingent consideration. Due to their short-term nature and/or liquidity, the carrying value of these instruments approximates their estimated fair values. See Note 3 for further information on the fair value of the Company’s investments. The fair value of contingent consideration was estimated using a discounted cash flow method described in Note 4.
	Long-Lived Assets, Goodwill and Indefinite-lived Intangible Assets
	Long-lived assets consist primarily of property and equipment, capitalized software, goodwill and other intangible assets. The Company reviews long-lived assets, including property and equipment and finite intangible assets, for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Conditions that would trigger an impairment assessment include, but are not limited to, a significant adverse change in legal factors or business climate that could affect the value of an asset or an adverse action or a significant decrease in the market price. A specifically identified intangible asset must be recorded as a separate asset from goodwill if either of the following two criteria is met: (1) the intangible asset acquired arises from contractual or other legal rights; or (2) the intangible asset is separable. Accordingly, intangible assets consist of specifically identified intangible assets. Goodwill is the excess of any purchase price over the estimated fair value of net tangible and intangible assets acquired.
	Goodwill and indefinite-lived intangible assets are not amortized but are reviewed annually for impairment or more frequently if impairment indicators arise. Separable intangible assets that are not deemed to have an indefinite life are amortized over their estimated useful lives, which range from two to ten years, using methods of amortization that are expected to reflect the estimated pattern of economic use, and are reviewed for impairment when events or changes in circumstances suggest that the assets may not be recoverable. Consistent with the Company’s determination that it has only one reporting segment, it has been determined that there is only one reporting unit and goodwill is tested for impairment at the entity level. The Company performs its annual test of impairment of goodwill as of December 31st of each year and whenever events or changes in circumstances suggest that the carrying amount may not be recoverable using the two step process required by ASC 350, Intangibles – Goodwill and Other. The first step of the impairment test is to identify potential impairment by comparing the reporting unit’s fair value with its net book value (or carrying amount), including goodwill. The fair value is estimated based on a market value approach. If the fair value of the reporting unit exceeds its carrying amount, the reporting unit’s goodwill is not considered to be impaired and the second step of the impairment test is not performed. Whenever indicators of impairment are present, the Company would perform the second step and compare the implied fair value of the reporting unit’s goodwill, as defined by ASC 350, to its carrying value to determine the amount of the impairment loss, if any. As of December 31, 2013, there are no indications of impairment based on the step one analysis, and the Company’s estimated fair value exceeded its goodwill carrying value by a significant margin.
	Based on the aforementioned evaluation, the Company believes that, as of the balance sheet date presented, none of the Company’s goodwill or other long-lived assets were impaired. The Company did not have any intangible assets with indefinite lives as of December 31, 2013 or 2012.
	Allowance for Doubtful Accounts
	The Company offsets gross trade accounts receivable with an allowance for doubtful accounts. The allowance for doubtful accounts is the Company’s best estimate of the amount of probable credit losses in their existing accounts receivable. The allowance for doubtful accounts is reviewed on a regular basis, and all past due balances are reviewed individually for collectability. Account balances are charged against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote. Provisions for doubtful accounts are recorded in general and administrative expense.
	Below is a summary of the changes in the Company’s allowance for doubtful accounts for the years ended December 31, 2013, 2012 and 2011.


			Balance at			Provision			Acquired in		Write-offs,			Balance at
			Beginning						Business		Net of			End of
			of Period						Combinations		Recoveries			Period
	Year ended December 31, 2011		$	1,026		$	316		$	—	$	(280	)	$	1,062
	Year ended December 31, 2012		$	1,062		$	827			—	$	(978	)	$	911
	Year ended December 31, 2013		$	911		$	564			—	$	(562	)	$	913
	Property and Equipment
	Property and equipment is stated at cost. Property and equipment acquired through acquisitions of businesses are initially recorded at fair value. Depreciation is calculated on the straight-line method based on the month the asset is placed in service over the following estimated useful lives:


			Estimated Useful Life
	Furniture and fixtures		5 years
	Computer equipment and software		2–3 years
	Internal-use software and website development costs		3–4 years
	Leasehold improvements		Shorter of useful life or remaining duration of lease
	Property and equipment consists of the following:


		As of December 31,
		2013			2012
Furniture and fixtures		$	848		$	1,277
Computer equipment and software			4,026			4,014
Leasehold improvements			1,294			1,362
Internal-use software and website development costs			15,028			12,817

			21,196			19,470
Less: accumulated depreciation and amortization			(11,739	)		(10,653	)

		$	9,457		$	8,817

Depreciation expense was $3.8 million, $3.3 million and $2.8 million for the years ended December 31, 2013, 2012 and 2011, respectively. Repairs and maintenance charges that do not increase the useful life of the assets are charged to operations as incurred. The Company wrote off approximately $2.7 million, $0.8 million and $1.3 million of fully depreciated assets that were no longer in service during 2013, 2012 and 2011, respectively.
Depreciation expense is classified as a component of operating expense in the Company’s results of operations.
Internal-Use Software and Website Development Costs
The Company capitalizes costs incurred during the development of its website applications and infrastructure as well as certain costs relating to internal-use software. The estimated useful life of costs capitalized is evaluated for each specific project. Capitalized internal-use software and website development costs are reviewed for recoverability whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. An impairment loss would be recognized only if the carrying amount of the asset is not recoverable and exceeds its fair value. The Company capitalized internal-use software and website development costs of $3.6 million, $3.0 million and $3.2 million for the years ended December 31, 2013, 2012 and 2011, respectively.
Concentrations of Credit Risk and Off-Balance Sheet Risk
Financial instruments that potentially expose the Company to concentrations of credit risk consist mainly of cash and cash equivalents, investments and accounts receivable. The Company maintains its cash and cash equivalents and investments principally in accredited financial institutions of high credit standing. The Company routinely assesses the credit worthiness of its customers. The Company generally has not experienced any significant losses related to individual customers or groups of customers in any particular industry or area. The Company does not require collateral. Due to these factors, no additional credit risk beyond amounts provided for collection losses is believed by management to be probable in the Company’s accounts receivable.
No single customer represented 10% or more of total accounts receivable at December 31, 2013 or 2012. No single customer accounted for 10% or more of total revenue in the year ended December 31, 2013. One customer accounted for both 12.0% and 12.8% of total revenue for the years ended December 31, 2012 and 2011, respectively.
Income Taxes
The Company’s deferred tax assets and liabilities are recognized based on temporary differences between the financial reporting and income tax bases of assets and liabilities using statutory rates. A valuation allowance is established against net deferred tax assets if, based upon the weight of available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized. The Company records a liability for unrecognized tax benefits resulting from uncertain tax positions taken or expected to be taken in a tax return using a “more likely than not” threshold as required by the provisions of ASC 740-10, Accounting for Uncertainty in Income Taxes.
The Company recognizes any interest and penalties related to unrecognized tax benefits in income tax expense.
Stock-Based Compensation
The Company has two stock-based employee compensation plans which are more fully described in Note 10. Stock-based compensation cost is measured at the grant date based on the fair value of the award and is recognized in the Consolidated Statement of Comprehensive (Loss) Income using the straight-line method over the vesting period of the award or using the accelerated method if the award is contingent upon performance goals. The Company uses the Black-Scholes option-pricing model to determine the fair value of stock option awards.
Comprehensive (Loss) Income
Comprehensive (loss) income includes all changes in equity during a period, except those resulting from investments by stockholders and distributions to stockholders. The Company’s comprehensive (loss) income includes changes in the fair value of the Company’s unrealized (losses) gains on available for sale securities and foreign currency translation.
Foreign Currency
The functional currency for each of the Company’s subsidiaries is each country’s local currency. All assets and liabilities are translated into U.S. dollar equivalents at either the exchange rate in effect on the balance sheet date or at a historical rate. Revenues and expenses are translated at average exchange rates. Translation gains or losses are recorded in stockholders’ equity as an element of accumulated other comprehensive income (loss).

Net (Loss) Income Per Share
Basic earnings per share is computed based on the weighted average number of common shares and vested restricted stock awards outstanding during the period. Because the holders of unvested restricted stock awards do not have nonforfeitable rights to dividends or dividend equivalents, the Company does not consider these awards to be participating securities that should be included in its computation of earnings per share under the two-class method. Diluted earnings per share is computed using the weighted average number of common shares and vested restricted stock awards outstanding during the period, plus the dilutive effect of potential future issuances of common stock relating to stock option programs and other potentially dilutive securities using the treasury stock method. In calculating diluted earnings per share, the dilutive effect of stock options and restricted stock awards is computed using the average market price for the respective period. In addition, the assumed proceeds under the treasury stock method include the average unrecognized compensation expense and assumed tax benefit of stock options and restricted stock awards that are in-the-money. This results in the “assumed” buyback of additional shares, thereby reducing the dilutive impact of stock options and restricted stock awards.
A reconciliation of the numerator and denominator used in the calculation of basic and diluted net (loss) income per share is as follows:

-1	Shares used to calculate diluted earnings per share exclude 0.5 million shares related to outstanding stock options and unvested restricted stock awards for the year ended December 31, 2013 that would have been dilutive if the Company had net income during that period. Additionally, in calculating diluted earnings per share, 5.3 million, 4.2 million and 2.7 million shares related to outstanding stock options and unvested restricted stock awards were excluded for the years ended December 31, 2013, 2012 and 2011, respectively, because they were anti-dilutive.
Recent Accounting Pronouncements
In July 2013, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. 2013-11, Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists (“ASU 2013-11”) to provide guidance on the presentation of unrecognized tax benefits. ASU 2013-11 requires an entity to present an unrecognized tax benefit, or a portion of an unrecognized tax benefit, as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward, except as follows: to the extent a net operating loss carryforward, a similar tax loss, or a tax credit carryforward is not available at the reporting date under the tax law of the applicable jurisdiction to settle any additional income taxes that would result from the disallowance of a tax position or the tax law of the applicable jurisdiction does not require the entity to use, and the entity does not intend to use, the deferred tax asset for such purpose, the unrecognized tax benefit should be presented in the financial statements as a liability and should not be combined with deferred tax assets. ASU 2013-11 is effective for the Company in the first quarter of fiscal 2014 with earlier adoption permitted. ASU 2013-11 should be applied prospectively with retroactive application permitted. The Company is currently evaluating the impact of the pending adoption of ASU 2013-11 on its consolidated financial statements starting in 2014.
In February 2013, the FASB issued ASU No. 2013-02, Comprehensive Income – Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income, which requires additional disclosure about material changes in the components of accumulated other comprehensive income, including amounts reclassified and amounts due to current period other comprehensive income. The standard was effective in the first quarter of fiscal 2013. The Company has not adopted the disclosure provisions required by this ASU as there are no material components of accumulated other comprehensive income nor have there been any material reclassifications out of accumulated other comprehensive income during the periods ended December 31, 2013, 2012 or 2011.

	3. Fair Value Measurements
	The Company measures certain financial assets and liabilities at fair value on a recurring basis, including cash equivalents, short-term and long-term investments and contingent consideration. The fair value of these financial assets and liabilities was determined based on three levels of input as follows:

		•		Level 1. Quoted prices in active markets for identical assets and liabilities;

		•		Level 2. Observable inputs other than quoted prices in active markets; and

		•		Level 3. Unobservable inputs.

	The fair value hierarchy of the Company’s financial assets and liabilities carried at fair value and measured on a recurring basis is as follows:

	4. Acquisitions
	LeMagIT
	On December 17, 2012 the Company purchased all of the outstanding shares of its French partner, E-Magine Médias SAS, for approximately $2.2 million in cash plus a potential future earnout valued at $0.7 million at the time of the acquisition. Approximately $1.2 million of the cash payment was made at closing, with the remainder due in two equal installments in fiscal years 2013 and 2014. The third installment is subject to certain revenue growth targets and may be reduced based on actual results. If all targets are met or exceeded, the total purchase price, including the earnout, shall not exceed approximately $5.2 million, depending on exchange rates at the time of calculation. The installment payments have been recorded at present value using a discount rate of 10%; the discount will be amortized to interest through the payment dates. The second installment was paid in 2013. The third installment, to be paid in 2014, is included in accrued liabilities in the Company’s consolidated balance sheet; the earnout is included in non-current liabilities.
	In connection with this acquisition, the Company’s allocation of purchase price was approximately $0.3 million of net tangible assets, $1.3 million of goodwill and $2.0 million of intangible assets related to developed websites, customer relationships, a member database, a non-compete agreement and trade names with estimated useful lives ranging from three to ten years, offset by a deferred tax liability in the amount of $0.7 million. Goodwill is attributable primarily to expected synergies from combining operations as well as intangible assets that do not qualify for recognition, such as an assembled workforce.
	The estimated fair value of the $2.0 million of acquired intangible assets is assigned as follows:


		Useful Life		Estimated Fair
		Useful Life		Value (in 000’s)
	Developed websites		120 months	$	1,474
	Customer relationship		60 months		118
	Member database		60 months		145
	Non-compete agreement		36 months		92
	Trade name		96 months		211

	Total intangible assets			$	2,040

	The Company engaged a third party valuation specialist to assist management in determining the fair value of the intangible assets of LeMagIT as well as the contingent consideration related to the transaction. To value the developed website assets an income approach was used, specifically a variation of the discounted cash-flow method known as the multi-period excess earnings method. The projected net cash flows were discounted using a discount rate of 28%. To value the customer relationship and trade name assets, a relief from royalty method was used to estimate the pre-tax royalty savings to the Company of owning the customer relationships and trade name related to LeMagIT directly rather than having to pay to use the asset. The projected net cash flows from the pre-tax royalty savings were tax affected using an effective rate of 33.3% and then discounted using a discount rate of 28% to calculate the value of the customer relationship and trade name intangible assets. To value the member database, a replacement cost approach was used, specifically a calculation of costs to acquire new members by taking the cost of a member list acquired by LeMagIT in 2012, applying a premium of 50% per member, and multiplying it times the total number of active members at the valuation date. This value was tax effected using an effective rate of 33.3%. Additionally, a tax benefit multiplier of 1.141 was applied to the value of the member database to arrive at the total fair value of the member database asset. To value the non-compete agreement, a comparative business valuation method was used. Based on a non-compete term of 36 months, management projected net cash flows for the Company with and without the non-compete agreement in place. The present value of the sum of the difference between the net cash flows with and without the non-compete agreement in place was calculated, based on a discount rate of 27%.
	Contingent consideration related to this acquisition consists of a potential earnout as well as the final payment, both of which are subject to future revenue targets and may differ from the amounts that are ultimately payable based on the final calculations. In valuing the contingent consideration it was determined that fair value adjustments were necessary to appropriately reflect the inherent risk and related time value of money associated with these potential payments. Accordingly, discount rates of 28% and 10% were used for the earnout and the third installment, respectively. The calculation of these fair values required the use of significant inputs that are not observable in the market and thus represent a Level 3 fair value measurement as defined in ASC 820. The significant inputs in the Level 3 measurements not supported by market activity include estimated future revenues as well as the rates used to discount them.
	Financial results of LeMagIT are included in the consolidated financial statements from the date of acquisition. These results were not material to the consolidated financial statements. Financial results of LeMagIT prior to the date of acquisition are not material to the Company’s results and, therefore, pro forma financials have not been included.
	Computer Weekly
	On April 26, 2011 the Company acquired the websites, product offerings, and events associated with Computer Weekly and its sister channel-targeted brand, MicroScope, from Reed Business Information Limited for approximately $2.0 million in cash. Additionally, the Company incurred approximately $0.4 million in restructuring costs relating to redundancy costs of Computer Weekly employees not brought over as part of the acquisition.
	In connection with this acquisition, the Company’s allocation of purchase price was approximately $40 of net tangible assets, $0.1 million of goodwill and $1.9 million of intangible assets related to customer relationships, a member database, a non-compete agreement and trade names with estimated useful lives ranging from two to five years.
	The estimated fair value of the $1.9 million of acquired intangible assets is assigned as follows:


		Useful Life		Estimated
		Useful Life		Fair Value
	Customer relationship		60 months	$	825
	Member database		60 months		512
	Non-compete agreement		24 months		100
	Trade name		60 months		430

	Total intangible assets			$	1,867


	The Company engaged a third party valuation specialist to assist management in determining the fair value of the intangible assets of the Computer Weekly and MicroScope businesses. To value the customer relationship assets, an income approach was used, specifically a variation of the discounted cash-flow method known as the multi-period excess earnings method. The projected net cash flows were discounted using a discount rate of 28.3%. To value the member database, a replacement cost approach was used, specifically a calculation of costs to acquire new members based on the cost to acquire new members in 2010 divided by new members acquired. Additionally, the present value of the sum of projected lost profits was added to the calculated replacement cost to calculate the total fair value of the member database asset. To value the non-compete agreement, a comparative business valuation method was used. Based on a non-compete term of 24 months, management projected net cash flows for the Company with and without the non-compete agreement in place. The present value of the sum of the difference between the net cash flows with and without the non-compete agreement in place was calculated, based on a discount rate of 28.3%. To value the trade name intangible asset, a relief from royalty method was used to estimate the pre-tax royalty savings to the Company related to the Computer Weekly and MicroScope trade names. The projected net cash flows from the pre-tax royalty savings were tax affected using an effective rate of 26% and then discounted using a discount rate of 28.3% to calculate the value of the trade name intangible asset.

	5. Cash, Cash Equivalents and Investments
	Cash and cash equivalents consist of highly liquid investments with maturities of three months or less at date of purchase. Cash equivalents are carried at cost, which approximates their fair market value. Cash and cash equivalents consisted of the following:


		As of December 31,
		2013		2012
	Cash	$	13,805	$	15,064
	Money market funds		1,607		33,345

	Total cash and cash equivalents	$	15,412	$	48,409

	The Company’s short and long-term investments are accounted for as available for sale securities. These investments are recorded at fair value with the related unrealized gains and losses included in accumulated other comprehensive income (loss), a component of stockholders’ equity, net of tax. The unrealized gain, net of taxes, was $10, $14 and $12 as of December 31, 2013, 2012 and 2011, respectively. Realized gains and losses on the sale of these investments are determined using the specific identification method. There were realized gains of approximately $23 in 2013; there were no realized gains or losses in 2012 or 2011.

	Short and long-term investments consisted of the following:


		December 31, 2013

	The Company had two debt securities in an unrealized loss position at December 31, 2013. Both of these securities have been in such a position for no more than 20 months. The unrealized loss on those securities was approximately $1 and the fair value was $1.8 million. As of December 31, 2013, the Company does not consider these investments to be other-than-temporarily impaired.
	Municipal and government agency bonds have contractual maturity dates that range from June 2014 to December 2015. All income generated from these investments is recorded as interest income.

	Intangible assets are amortized over their estimated useful lives, which range from two to ten years, using methods of amortization that are expected to reflect the estimated pattern of economic use. The remaining amortization expense will be recognized over a weighted-average period of approximately 2.7 years. Amortization expense was $2.2 million, $3.4 million and $4.0 million for the years ended December 31, 2013, 2012 and 2011, respectively. Amortization expense is recorded within operating expenses as the intangible assets consist of customer-related assets and website traffic that the Company considers to be in support of selling and marketing activities. The Company wrote off $6.2 million and $7.6 million of fully amortized intangible assets in 2012 and 2011, respectively. The Company did not write off any amortized intangible assets in 2013.
	The Company expects amortization expense of intangible assets to be as follows:

Credit Facility	'
	8. Credit Facility
	The Company’s $5.0 million revolving credit facility was amended in August 2011, extending its term and adjusting certain other financial terms and covenants. Unless earlier payment is required by an event of default, all principal and unpaid interest will be due and payable on August 31, 2016. At the Company’s option, the Revolving Credit Facility (the “Credit Agreement”) bears interest at either the prime rate less 1.00% or the London Interbank Offered Rate (“LIBOR”) plus the applicable LIBOR margin. The applicable LIBOR margin is based on the ratio of total funded debt to earnings before interest, other income and expense, income taxes, depreciation, and amortization (“EBITDA”) for the preceding four fiscal quarters. As of December 31, 2013, the applicable LIBOR margin was 1.25%.
	The Company is also required to pay an unused line fee on the daily unused amount of the Credit Agreement at a per annum rate based on the ratio of total funded debt to EBITDA for the preceding four fiscal quarters. As of December 31, 2013, the per annum unused line fee rate was 0.20%.
	At December 31, 2013 and December 31, 2012 there were no amounts outstanding under the Credit Agreement. Pursuant to the Credit Agreement, there was a $1.0 million standby letter of credit related to the Company’s corporate headquarters lease outstanding at December 31, 2013, bringing the Company’s available borrowings on the $5.0 million facility to $4.0 million.
	Borrowings under the Credit Agreement are collateralized by a security interest in substantially all assets of the Company. Covenants governing the Credit Agreement include the maintenance of certain financial ratios. At December 31, 2013, with the exception of the ratio for Minimum Fixed Charge Coverage, for which a waiver was granted, the Company was in compliance with all required covenants under the Credit Agreement.

	Operating Leases
	The Company conducts its operations in leased office facilities under various noncancelable operating lease agreements that expire through March 2020. In August 2009, the Company entered into an agreement to lease approximately 87,875 square feet of office space in Newton, Massachusetts. The lease commenced in February 2010 and has a term of ten years. The Company is receiving certain rent concessions over the life of the lease. In November 2010, the Newton lease was amended to include an additional 8,400 square feet of office space. The amended lease commenced in March 2011 and runs concurrently with the term of the original lease. The Company is receiving certain rent concessions over the life of the amended lease.
	Certain of the Company’s operating leases include lease incentives and escalating payment amounts and are renewable for varying periods. The Company is recognizing the related rent expense on a straight-line basis over the term of the lease taking into account the lease incentives and escalating lease payments. Total rent expense under the Company’s leases was approximately $4.0 million for each of the years ended December 31, 2013, 2012 and 2011.
	Future minimum lease payments under the Company’s noncancelable operating leases at December 31, 2013 are as follows:


	Years Ending December 31:	Minimum
		Lease
		Payments
	2014	$	4,321
	2015		3,559
	2016		3,582
	2017		3,290
	2018		3,404
	Thereafter		4,002

		$	22,158


	At December 31, 2013, the Company had an irrevocable standby letter of credit outstanding in the aggregate amount of $1.0 million. This letter of credit supports the lease the Company entered into in 2009 for its corporate headquarters. This letter of credit extends annually through February 28, 2020 unless notification of termination is received.
	Net Worth Tax Contingency
	In late March 2010, the Company received a letter from the Department of Revenue of the Commonwealth of Massachusetts (the “MA DOR”) requesting documentation demonstrating that TSC has been classified by the MA DOR as a Massachusetts security corporation. Following subsequent correspondence with the MA DOR and a settlement conference on March 22, 2011, the Company received on July 16, 2011 a Notice of Assessment from the MA DOR for 2006 and 2007 in the amount of approximately $198 (which amount included all interest and penalties to date) with respect to additional excise taxes on net worth related to TSC. Based on the Company’s previous assessment that it was probable that the MA DOR would require an adjustment to correct TSC’s tax filings such that it will be treated as a Massachusetts business corporation for the applicable years, for the year ended December 31, 2010, the Company recorded a liability of approximately $200, representing its best estimate at that time of the potential net worth tax exposure. The tax benefits available to a Massachusetts security corporation are comprised of (i) a different rate structure (1.32% on gross investment income vs. 9.5% on net income) and (ii) exemption from the 0.26% excise tax on net worth. On August 17, 2011, the Company filed Applications for Abatement with the MA DOR. On January 6, 2012, the Company filed Petitions for Formal Procedure with the Massachusetts Appellate Tax Board. The trial date has been re-scheduled for April 22, 2014. The Company intends to continue to dispute the assessment and believes it has meritorious defenses which, both directly and via claims against third parties, it intends to assert. The Company increased the reserve assessment to reflect additional interest accrued through December 31, 2013.
	Litigation
	From time to time and in the ordinary course of business, the Company may be subject to various claims, charges, and litigation. At December 31, 2013 and 2012, the Company did not have any pending claims, charges, or litigation that it expects would have a material adverse effect on its consolidated financial position, results of operations, or cash flows.

	10. Stock-Based Compensation
	Stock Option Plans
	In September 1999, the Company approved a stock option plan (the “1999 Plan”) that provides for the issuance of up to 12,384,646 shares of common stock incentives. The 1999 Plan provides for the granting of incentive stock options (“ISOs”), nonqualified stock options (“NSOs”), and stock grants. These incentives may be offered to the Company’s employees, officers, directors, consultants, and advisors, as defined. ISOs may not be granted at less than fair market value on the date of grant, as determined by the Company’s Board of Directors (the “Board”). Each option shall be exercisable at such times and subject to such terms as determined by the Board; grants generally vest over a four year period, and expire no later than ten years after the grant date.
	In April 2007, the Board approved the 2007 Stock Option and Incentive Plan (the “2007 Plan”), which was approved by the stockholders and became effective upon the consummation of the Company’s IPO in May 2007. Effective upon the consummation of the IPO, no further awards were made pursuant to the 1999 Plan, but any outstanding awards under the 1999 Plan will remain in effect and will continue to be subject to the terms of the 1999 Plan. The 2007 Plan allows the Company to grant ISOs, NSOs, stock appreciation rights, deferred stock awards, restricted stock and other awards. Under the 2007 Plan, stock options may not be granted at less than fair market value on the date of grant, and grants generally vest over a four year period. Stock options granted under the 2007 Plan expire no later than ten years after the grant date. The Company has reserved for issuance an aggregate of 2,911,667 shares of common stock under the 2007 Plan plus an additional annual increase to be added automatically on January 1 of each year, beginning on January 1, 2008, equal to the lesser of (a) 2% of the outstanding number of shares of common stock (on a fully-diluted basis) on the immediately preceding December 31 and (b) such lower number of shares as may be determined by the Company’s compensation committee. The number of shares available for issuance under the 2007 Plan is subject to adjustment in the event of a stock split, stock dividend or other change in capitalization. Generally, shares that are forfeited or canceled from awards under the 2007 Plan also will be available for future awards. To date, approximately 5.9 million shares have been added to the 2007 Plan in accordance with the automatic annual increase. In addition, shares subject to stock options returned to the 1999 Plan, as a result of their expiration, cancellation or termination, are automatically made available for issuance under the 2007 Plan. As of December 31, 2013 a total of 1,319,233 shares were available for grant under the 2007 Plan.
	Accounting for Stock-Based Compensation
	The Company uses the Black-Scholes option pricing model to calculate the grant-date fair value of an award. The Company calculated the fair values of the options granted using the following estimated weighted-average assumptions:


			Years Ended December 31,
			2013		2012	2011
	Expected volatility		67%		88%	79%-81.4%
	Expected term		5 years		5 years	6.25 years
	Risk-free interest rate		0.58%		0.36%	0.9%-2.3%
	Expected dividend yield		—%		—%	—%
	Weighted-average grant date fair value per share		$3.89		$3.63	$4.72
	As there was no public market for the Company’s common stock prior to the Company’s IPO in May 2007 and, until recently, limited historical information on the volatility of its common stock since the date of the Company’s IPO, the Company has historically determined the volatility for options granted based on an analysis of the Company’s stock and reported data for a peer group of companies that issued options with substantially similar terms. The expected volatility of options granted in 2013 has been determined using a weighted average of the historical volatility of the Company’s stock for a period equal to the expected life of the option; a combined historical volatility of the Company’s stock and the peer group of companies was used in prior years. The expected life of options has been determined utilizing the “simplified” method. The risk-free interest rate is based on a zero coupon United States treasury instrument whose term is consistent with the expected life of the stock options. The Company has not paid and does not anticipate paying cash dividends on its shares of common stock; therefore, the expected dividend yield is assumed to be zero. The Company applied an estimated annual forfeiture rate based on its historical forfeiture experience of 4.44%, 4.17% and 3.6% in determining the expense recorded in 2013, 2012, and 2011, respectively.

	A summary of the stock option activity under the Company’s stock option plan for the year ended December 31, 2013 is presented below:


			Options			Weighted-Average		Weighted-Average		Aggregate
			Outstanding			Exercise		Remaining		Intrinsic
						Price Per Share		Contractual		Value

	Options vested or expected to vest at December 31, 2013(1)			4,462,875		$	7.3		3.4	$	2,415


	-1	In addition to the vested options, the Company expects a portion of the unvested options to vest at some point in the future. Options expected to vest is calculated by applying an estimated forfeiture rate to the unvested options.
	During the years ended December 31, 2013, 2012 and 2011, the total intrinsic value of options exercised (i.e. the difference between the market price at exercise and the price paid by the employee to exercise the options) was $1.4 million, $0.2 million and $3.8 million, respectively, and the total amount of cash received by the Company from exercise of these options was $1.6 million, $0.8 million and $2.8 million, respectively. The total grant date fair value of stock options granted after January 1, 2006 that vested during the years ended December 31, 2013, 2012 and 2011 was $0.7 million, $1.5 million and $2.5 million, respectively.
	Restricted Stock Awards
	Restricted stock awards are valued at the market price of a share of the Company’s common stock on the date of the grant. A summary of the restricted stock award activity under the 2007 Plan for the year ended December 31, 2013 is presented below:


			Shares			Weighted-Average		Aggregate
						Grant Date		Intrinsic
						Fair Value		Value
						Per Share

	Nonvested outstanding at December 31, 2013			2,777,500		$	5.26	$	19,054

	The total grant-date fair value of restricted stock awards that vested during the years ended December 31, 2013, 2012 and 2011 was $5.0 million, $4.2 million and $6.0 million, respectively. As of December 31, 2013, there was $12.5 million of total unrecognized compensation expense related to stock options and restricted stock awards which is expected to be recognized over a weighted average period of 2.2 years.

	Tender Offer
	On September 25, 2013, the Company commenced a tender offer to purchase up to 6.5 million shares of its common stock, representing approximately 16.79% of the shares of TechTarget’s common stock issued and outstanding at that time, at a price of $5.00 per share. On September 23, 2013, the last reported sale price of the Company’s common stock was $4.79 per share.
	The tender offer expired on October 24, 2013. In accordance with applicable SEC regulations and the terms of the tender offer, the Company exercised the right to purchase additional shares and based on the final tabulation by Computershare Trust Company, N.A., the Depositary for the tender offer, the Company accepted for purchase 7,100,565 shares of its common stock for a total cost of $35.5 million. Repurchased shares are recorded under the cost method and are reflected as treasury stock in the accompanying Consolidated Balance Sheets. The total cost of the tender offer was $35.6 million, which includes approximately $0.1 million in costs directly attributable to the purchase.
	Reserved Common Stock
	As of December 31, 2013, the Company has reserved 8,978,982 shares of common stock for options outstanding and restricted stock awards that have not been issued as well as those available for grant under the stock option plans.
	Common Stock Repurchase Program
	On August 3, 2012, the Company’s Board of Directors authorized a $20 million stock repurchase program (the “Program”) authorizing the Company to repurchase its common stock from time to time on the open market or in privately negotiated transactions. The timing and amount of any shares repurchased was determined based on an evaluation of market conditions and other factors. The Company elected to implement a Rule 10b5-1 trading plan to make such purchases, which permits shares to be repurchased when the Company might otherwise be precluded from doing so under insider trading laws. The Program was terminated immediately prior to the commencement of the tender offer on September 25, 2013.
	During the year ended December 31, 2013 the Company repurchased 2,610,279 shares of common stock for $12.4 million pursuant to the Program. During the year ended December 31, 2012 the Company repurchased 95,940 shares of common stock for $467 pursuant to the Program. Repurchased shares are recorded under the cost method and are reflected as treasury stock in the accompanying Consolidated Balance Sheets. All repurchased shares were funded with cash on hand.
	Preferred Shares Authorized
	In April 2007, the Board of Directors authorized 5,000,000 shares of undesignated preferred stock, par value $0.001 per share. No preferred shares have been issued as of December 31, 2013.

Non-current deferred tax assets		$	5,873			$	7,457

Non-current deferred tax liabilities		$	(745	)		$	(702	)

In evaluating the ability to realize the net deferred tax asset, the Company considers all available evidence, both positive and negative, including past operating results, the existence of cumulative losses in the most recent fiscal years, tax planning strategies that are prudent and feasible, and forecasts of future taxable income. In considering sources of future taxable income, the Company makes certain assumptions and judgments which are based on the plans and estimates used to manage the underlying business of the Company. Changes in the Company’s assumptions and estimates may materially impact income tax expense for the period. The valuation allowance of $1,158 and $1,058 at December 31, 2013 and 2012, respectively, relates to foreign net operating losses (“NOL’s”) and state NOL’s acquired from KnowledgeStorm that the Company determined were not more likely than not to be realized based on projections of future taxable income in California, Georgia, China and Hong Kong. The valuation allowance increased by $100, $231 and $149 during the years ended December 31, 2013, 2012 and 2011, respectively. To the extent realization of the deferred tax assets for foreign and the state net operating losses becomes more likely than not, recognition of these acquired tax benefits would reduce income tax expense.
The Company expects to generate a federal net operating loss for the 2013 tax year. The Company intends to carry the NOL back to the prior year to generate a tax refund of $2.3 million.
The Company considers the excess of its financial reporting over its tax basis in its investment in foreign subsidiaries essentially permanent in duration and as such has not recognized a deferred tax liability related to this difference.
The amount of unrecognized tax benefits at December 31, 2013 was approximately $0.7 million. The amount of unrecognized tax benefits that impact the effective tax rate, if recognized, is approximately $0.5 million.

A reconciliation of the beginning and ending amounts of unrecognized tax benefits for the years ended December 31, 2013 and 2012 is as follows:


		2013				2012
Balance at beginning of year		$	642			$	628
Gross increases related to positions taken in prior periods			15				14

Balance at end of year		$	657			$	642

In March 2010, the Company received a letter from the Department of Revenue of the Commonwealth of Massachusetts (the “MA DOR”) requesting documentation demonstrating that TechTarget Securities Corporation (“TSC”), a wholly-owned subsidiary of the Company, has been classified by the MA DOR as a Massachusetts security corporation. Based on subsequent correspondence with the MA DOR, the Company determined that it was more likely than not that the MA DOR would require an adjustment to correct TSC’s tax filings such that it will be treated as a Massachusetts business corporation for the applicable years. The tax benefit available to a Massachusetts security corporation is a lower income tax rate. For the year ended December 31, 2010, the Company recorded a tax reserve for approximately $0.4 million for the potential state income tax liability arising from the difference between the income tax rates applicable to security corporations and business corporations in Massachusetts. On August 17, 2011, the Company filed Applications for Abatement with the MA DOR. On January 6, 2012, the Company filed Petitions under Formal Procedure with the Massachusetts Appellate Tax Board. The trial date has been rescheduled for April 22, 2014. The Company intends to continue to dispute the assessment and believes it has meritorious defenses which it intends to vigorously assert.
The Company recognized interest and penalties totaling $15 on its uncertain tax positions in income tax expense in 2013. Tax years 2010 through 2013 are subject to examination by the federal and state taxing authorities.
The Company recently finalized the IRS audit related to the 2009 and 2010 federal tax returns without any adjustments. The State of New York audit for the 2008 through 2010 returns was closed during the period. The State of New York assessed $3 for state income tax liability related to this audit.
As of December 31, 2013, the Company had state NOL carryforwards of approximately $25.9 million, which may be used to offset future taxable income. The NOL carryforwards expire at various dates through 2034. The Company has foreign NOL carryforwards of $0.9 million, which may be used to offset future taxable income in foreign jurisdictions until they expire, through 2018.

Accounting Policies [Abstract]	'
Principles of Consolidation	'
	Principles of Consolidation
	The accompanying Consolidated Financial Statements include the accounts of the Company and its wholly-owned subsidiaries, which are comprised of KnowledgeStorm, Inc., Bitpipe, Inc., TechTarget Securities Corporation (“TSC”), TechTarget Limited, TechTarget (HK) Limited, TechTarget (Beijing) Information Technology Consulting Co., Ltd., TechTarget (Australia) Pty Ltd., TechTarget (Singapore) Pte Ltd. and E-Magine Médias SAS. KnowledgeStorm, Inc. and Bitpipe, Inc. feature websites that provide in-depth vendor generated content targeted to corporate IT professionals. TechTarget Securities Corporation is a Massachusetts security corporation incorporated in 2004. TechTarget Limited is a subsidiary doing business principally in the United Kingdom. TechTarget (HK) Limited (“TTGT HK”) is a subsidiary incorporated in Hong Kong in order to facilitate the Company’s activities in the Asia-Pacific region. Additionally, through its wholly-owned subsidiaries, TTGT HK and TechTarget (Beijing) Information Technology Consulting Co., Ltd. (“TTGT Consulting”, incorporated on December 16, 2011), the Company effectively controls a variable interest entity (“VIE”), Keji Wangtuo Information Technology Co., Ltd., (“KWIT”), which was incorporated under the laws of the People’s Republic of China (“PRC”) on November 27, 2007. TechTarget (Australia) Pty Ltd. (incorporated on December 15, 2011) and TechTarget (Singapore) Pte Ltd. (incorporated on February 12, 2012) are the entities through which the Company does business in Australia and Singapore, respectively and E-Magine Médias SAS (“LeMagIT”), a wholly-owned subsidiary of TechTarget Limited, is an entity through which the Company does business in France.
	PRC laws and regulations prohibit or restrict foreign ownership of Internet-related services and advertising businesses. To comply with these foreign ownership restrictions, the Company operates its websites and provides online advertising services in the PRC through KWIT. The Company entered into certain exclusive agreements with KWIT and its shareholders through TTGT HK, which obligated TTGT HK to absorb all of the risk of loss from KWIT’s activities and entitled TTGT HK to receive all of their residual returns. In addition, the Company entered into certain agreements with the authorized parties through TTGT HK, including Management and Consulting Services, Voting Proxy, Equity Pledge and Option Agreements. On December 31, 2011, TTGT HK assigned all of its rights and obligations to the newly formed wholly foreign-owned enterprise (“WFOE”), TTGT Consulting. The WFOE is established and existing under the laws of the PRC, and is wholly owned by TTGT HK.
	Based on these contractual arrangements, the Company consolidates the financial results of KWIT as required by Accounting Standards Codification (“ASC”) subtopic 810-10 (“ASC 810-10”), Consolidation: Overall, because the Company holds all the variable interests of KWIT through the WFOE, which is the primary beneficiary of KWIT. Despite the lack of technical majority ownership, there exists a parent-subsidiary relationship between the Company and the VIE through the aforementioned agreements, whereby the equity holders of KWIT assigned all of their voting rights underlying their equity interest in KWIT to the WFOE. In addition, through the other aforementioned agreements, the Company demonstrates its ability and intention to continue to exercise the ability to obtain substantially all of the profits and absorb all of the expected losses of KWIT. All significant intercompany accounts and transactions between the Company, its subsidiaries, and KWIT have been eliminated in consolidation.
Use of Estimates	'
	Use of Estimates
	The preparation of financial statements in conformity with Generally Accepted Accounting Principles (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. On an ongoing basis, the Company evaluates its estimates, including those related to revenue, long-lived assets, goodwill, the allowance for doubtful accounts, stock-based compensation, earnouts, self-insurance accruals and income taxes. Estimates of the carrying value of certain assets and liabilities are based on historical experience and on various other assumptions that the Company believes to be reasonable. Actual results could differ from those estimates.
Revenue Recognition	'
	Revenue Recognition
	The Company generates substantially all of its revenue from the sale of targeted advertising campaigns, which are delivered via its network of websites, and events. Revenue is recognized only when the price is fixed or determinable, persuasive evidence of an arrangement exists, the service is performed and collectability of the resulting receivable is reasonably assured.
	The majority of the Company’s online media sales involve multiple product offerings, which are described in more detail below. Because neither vendor-specific objective evidence of fair value nor third party evidence of fair value exists for all elements in the Company’s bundled product offerings, the Company uses an estimated selling price which represents management’s best estimate of the stand-alone selling price for each deliverable in an arrangement. The Company establishes best estimates considering multiple factors including, but not limited to, class of client, size of transaction, available media inventory, pricing strategies and market conditions. The Company believes the use of the best estimate of selling price allows revenue recognition in a manner consistent with the underlying economics of the transaction. The Company uses the relative selling price method to allocate consideration at the inception of the arrangement to each deliverable in a multiple element arrangement. The relative selling price method allocates any discount in the arrangement proportionately to each deliverable on the basis of the deliverable’s best estimated selling price. Revenue is then recognized as delivery occurs.
	The Company evaluates all deliverables of an arrangement at inception and each time an item is delivered, to determine whether they represent separate units of accounting. Based on this evaluation, the arrangement consideration is measured and allocated to each of these elements.

	Online Media. Revenue for lead generation campaigns is recognized as follows:
	Beginning in the period ended March 31, 2012, the Company’s lead generation campaigns all offer the Activity Intelligence™ Dashboard (the “Dashboard”). In order to manage the lead generation component, the Company changed its operational approach and the contractual terms and conditions under which it sells its products. Instead of contracting to sell individual elements, the Company sells various lead generation campaigns with the Dashboard. Accordingly, for duration-based campaigns, revenue is recognized ratably over the duration of the campaigns, which is usually less than six months. Lead generation offerings may also include an additional service, Nurture & Qualify (formerly called Nurture & Notify), in which case revenue is recognized ratably over the period of the campaign as a combined unit of accounting. As part of these lead generation campaign offerings, the Company will guarantee a minimum number of qualified leads to be delivered over the course of the advertising campaign. The Company determines the content necessary to achieve performance guarantees. Scheduled end dates of advertising campaigns sometimes need to be extended, pursuant to the terms of the arrangement, to satisfy lead guarantees. The Company estimates a revenue reserve necessary to adjust revenue recognition for extended advertising campaigns. These estimates are based on the Company’s experience in managing and fulfilling these offerings. The customer has cancellation privileges which generally require advance notice by the customer and require proportional payment by the customer for the portion of the campaign period provided by the Company. Additionally, the Company offers sales incentives to certain customers, primarily in the form of volume rebates, which are classified as a reduction of revenues and are calculated based on the terms of the specific customer’s contract. The Company accrues for these sales incentives based on contractual terms and historical experience.
	The Company recognizes revenue on contracts where pricing is based on cost per lead in the period during which the leads are delivered to its customers.
	Revenue for other significant online media offerings is recognized as follows:

		•		Custom Content Creation. Custom content revenue is recognized when the creation is completed and delivered to the customer, with the exception of microsites which are recognized over the period during which they are live.

		•		Content Sponsorships. Content sponsorship revenue is recognized ratably over the period in which the related content asset is available on the Company’s websites.

		•		List Rentals and IT Deal Alert™. List rental and IT Deal Alert revenue is recognized in the period in which the delivery of the report is made to the Company’s customer.

		•		Banners. Banner revenue is recognized in the period in which the banner impressions or clicks occur.

		•		Third Party Revenue Sharing Arrangements. Revenue from third party revenue sharing arrangements is recognized on a net basis in the period in which the services are performed. For certain third party agreements where the Company is the primary obligor, revenue is recognized on a gross basis in the period in which the services are performed.

		•		In 2011, revenue for elements of lead generation campaigns was recognized as follows:

		•		White Papers. White paper revenue was recognized ratably over the period in which the white paper was available on the Company’s websites.

		•		Webcasts, Podcasts, Videocasts and Virtual Trade Shows. Webcast, podcast, videocast, virtual trade show and similar content revenue was recognized ratably over the period in which the webcast, podcast, videocast or virtual trade show was available on the Company’s websites.
	Event Sponsorships. Revenue from vendor-sponsored events, whether sponsored exclusively by a single vendor or in a multi-vendor sponsored event, is recognized upon completion of the event in the period the event occurs. The majority of the Company’s events are free to qualified attendees; however, certain events are based on a paid attendee model. The Company recognizes revenue for paid attendee events upon completion of the event.

	Amounts collected or billed prior to satisfying the above revenue recognition criteria are recorded as deferred revenue. The Company excludes from its deferred revenue and accounts receivable balances amounts for which it has billed in advance prior to the start of a campaign or the delivery of services.
Fair Value of Financial Instruments	'
	Fair Value of Financial Instruments
	Financial instruments consist of cash and cash equivalents, short and long-term investments, accounts receivable, accounts payable and contingent consideration. Due to their short-term nature and/or liquidity, the carrying value of these instruments approximates their estimated fair values. See Note 3 for further information on the fair value of the Company’s investments. The fair value of contingent consideration was estimated using a discounted cash flow method described in Note 4.
Long-Lived Assets, Goodwill and Indefinite-lived Intangible Assets	'
	Long-Lived Assets, Goodwill and Indefinite-lived Intangible Assets
	Long-lived assets consist primarily of property and equipment, capitalized software, goodwill and other intangible assets. The Company reviews long-lived assets, including property and equipment and finite intangible assets, for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Conditions that would trigger an impairment assessment include, but are not limited to, a significant adverse change in legal factors or business climate that could affect the value of an asset or an adverse action or a significant decrease in the market price. A specifically identified intangible asset must be recorded as a separate asset from goodwill if either of the following two criteria is met: (1) the intangible asset acquired arises from contractual or other legal rights; or (2) the intangible asset is separable. Accordingly, intangible assets consist of specifically identified intangible assets. Goodwill is the excess of any purchase price over the estimated fair value of net tangible and intangible assets acquired.
	Goodwill and indefinite-lived intangible assets are not amortized but are reviewed annually for impairment or more frequently if impairment indicators arise. Separable intangible assets that are not deemed to have an indefinite life are amortized over their estimated useful lives, which range from two to ten years, using methods of amortization that are expected to reflect the estimated pattern of economic use, and are reviewed for impairment when events or changes in circumstances suggest that the assets may not be recoverable. Consistent with the Company’s determination that it has only one reporting segment, it has been determined that there is only one reporting unit and goodwill is tested for impairment at the entity level. The Company performs its annual test of impairment of goodwill as of December 31st of each year and whenever events or changes in circumstances suggest that the carrying amount may not be recoverable using the two step process required by ASC 350, Intangibles – Goodwill and Other. The first step of the impairment test is to identify potential impairment by comparing the reporting unit’s fair value with its net book value (or carrying amount), including goodwill. The fair value is estimated based on a market value approach. If the fair value of the reporting unit exceeds its carrying amount, the reporting unit’s goodwill is not considered to be impaired and the second step of the impairment test is not performed. Whenever indicators of impairment are present, the Company would perform the second step and compare the implied fair value of the reporting unit’s goodwill, as defined by ASC 350, to its carrying value to determine the amount of the impairment loss, if any. As of December 31, 2013, there are no indications of impairment based on the step one analysis, and the Company’s estimated fair value exceeded its goodwill carrying value by a significant margin.
	Based on the aforementioned evaluation, the Company believes that, as of the balance sheet date presented, none of the Company’s goodwill or other long-lived assets were impaired. The Company did not have any intangible assets with indefinite lives as of December 31, 2013 or 2012.
Allowance for Doubtful Accounts	'
	Allowance for Doubtful Accounts
	The Company offsets gross trade accounts receivable with an allowance for doubtful accounts. The allowance for doubtful accounts is the Company’s best estimate of the amount of probable credit losses in their existing accounts receivable. The allowance for doubtful accounts is reviewed on a regular basis, and all past due balances are reviewed individually for collectability. Account balances are charged against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote. Provisions for doubtful accounts are recorded in general and administrative expense.
	Below is a summary of the changes in the Company’s allowance for doubtful accounts for the years ended December 31, 2013, 2012 and 2011.


			Balance at			Provision			Acquired in		Write-offs,			Balance at
			Beginning						Business		Net of			End of
			of Period						Combinations		Recoveries			Period
	Year ended December 31, 2011		$	1,026		$	316		$	—	$	(280	)	$	1,062
	Year ended December 31, 2012		$	1,062		$	827			—	$	(978	)	$	911
	Year ended December 31, 2013		$	911		$	564			—	$	(562	)	$	913
Property and Equipment	'
	Property and Equipment
	Property and equipment is stated at cost. Property and equipment acquired through acquisitions of businesses are initially recorded at fair value. Depreciation is calculated on the straight-line method based on the month the asset is placed in service over the following estimated useful lives:


			Estimated Useful Life
	Furniture and fixtures		5 years
	Computer equipment and software		2–3 years
	Internal-use software and website development costs		3–4 years
	Leasehold improvements		Shorter of useful life or remaining duration of lease
	Property and equipment consists of the following:


			As of December 31,
			2013			2012
	Furniture and fixtures		$	848		$	1,277
	Computer equipment and software			4,026			4,014
	Leasehold improvements			1,294			1,362
	Internal-use software and website development costs			15,028			12,817

				21,196			19,470
	Less: accumulated depreciation and amortization			(11,739	)		(10,653	)

			$	9,457		$	8,817

	Depreciation expense was $3.8 million, $3.3 million and $2.8 million for the years ended December 31, 2013, 2012 and 2011, respectively. Repairs and maintenance charges that do not increase the useful life of the assets are charged to operations as incurred. The Company wrote off approximately $2.7 million, $0.8 million and $1.3 million of fully depreciated assets that were no longer in service during 2013, 2012 and 2011, respectively.
	Depreciation expense is classified as a component of operating expense in the Company’s results of operations.
Internal-Use Software and Website Development Costs	'
	Internal-Use Software and Website Development Costs
	The Company capitalizes costs incurred during the development of its website applications and infrastructure as well as certain costs relating to internal-use software. The estimated useful life of costs capitalized is evaluated for each specific project. Capitalized internal-use software and website development costs are reviewed for recoverability whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. An impairment loss would be recognized only if the carrying amount of the asset is not recoverable and exceeds its fair value. The Company capitalized internal-use software and website development costs of $3.6 million, $3.0 million and $3.2 million for the years ended December 31, 2013, 2012 and 2011, respectively.
Concentrations of Credit Risk and Off-Balance Sheet Risk	'
	Concentrations of Credit Risk and Off-Balance Sheet Risk
	Financial instruments that potentially expose the Company to concentrations of credit risk consist mainly of cash and cash equivalents, investments and accounts receivable. The Company maintains its cash and cash equivalents and investments principally in accredited financial institutions of high credit standing. The Company routinely assesses the credit worthiness of its customers. The Company generally has not experienced any significant losses related to individual customers or groups of customers in any particular industry or area. The Company does not require collateral. Due to these factors, no additional credit risk beyond amounts provided for collection losses is believed by management to be probable in the Company’s accounts receivable.
	No single customer represented 10% or more of total accounts receivable at December 31, 2013 or 2012. No single customer accounted for 10% or more of total revenue in the year ended December 31, 2013. One customer accounted for both 12.0% and 12.8% of total revenue for the years ended December 31, 2012 and 2011, respectively.
Income Taxes	'
	Income Taxes
	The Company’s deferred tax assets and liabilities are recognized based on temporary differences between the financial reporting and income tax bases of assets and liabilities using statutory rates. A valuation allowance is established against net deferred tax assets if, based upon the weight of available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized. The Company records a liability for unrecognized tax benefits resulting from uncertain tax positions taken or expected to be taken in a tax return using a “more likely than not” threshold as required by the provisions of ASC 740-10, Accounting for Uncertainty in Income Taxes.
	The Company recognizes any interest and penalties related to unrecognized tax benefits in income tax expense.
Stock-Based Compensation	'
	Stock-Based Compensation
	The Company has two stock-based employee compensation plans which are more fully described in Note 10. Stock-based compensation cost is measured at the grant date based on the fair value of the award and is recognized in the Consolidated Statement of Comprehensive (Loss) Income using the straight-line method over the vesting period of the award or using the accelerated method if the award is contingent upon performance goals. The Company uses the Black-Scholes option-pricing model to determine the fair value of stock option awards.
Comprehensive (Loss) Income	'
	Comprehensive (Loss) Income
	Comprehensive (loss) income includes all changes in equity during a period, except those resulting from investments by stockholders and distributions to stockholders. The Company’s comprehensive (loss) income includes changes in the fair value of the Company’s unrealized (losses) gains on available for sale securities and foreign currency translation.
Foreign Currency	'
	Foreign Currency
	The functional currency for each of the Company’s subsidiaries is each country’s local currency. All assets and liabilities are translated into U.S. dollar equivalents at either the exchange rate in effect on the balance sheet date or at a historical rate. Revenues and expenses are translated at average exchange rates. Translation gains or losses are recorded in stockholders’ equity as an element of accumulated other comprehensive income (loss).
Net (Loss) Income Per Share	'
	Net (Loss) Income Per Share
	Basic earnings per share is computed based on the weighted average number of common shares and vested restricted stock awards outstanding during the period. Because the holders of unvested restricted stock awards do not have nonforfeitable rights to dividends or dividend equivalents, the Company does not consider these awards to be participating securities that should be included in its computation of earnings per share under the two-class method. Diluted earnings per share is computed using the weighted average number of common shares and vested restricted stock awards outstanding during the period, plus the dilutive effect of potential future issuances of common stock relating to stock option programs and other potentially dilutive securities using the treasury stock method. In calculating diluted earnings per share, the dilutive effect of stock options and restricted stock awards is computed using the average market price for the respective period. In addition, the assumed proceeds under the treasury stock method include the average unrecognized compensation expense and assumed tax benefit of stock options and restricted stock awards that are in-the-money. This results in the “assumed” buyback of additional shares, thereby reducing the dilutive impact of stock options and restricted stock awards.
	A reconciliation of the numerator and denominator used in the calculation of basic and diluted net (loss) income per share is as follows:

	-1	Shares used to calculate diluted earnings per share exclude 0.5 million shares related to outstanding stock options and unvested restricted stock awards for the year ended December 31, 2013 that would have been dilutive if the Company had net income during that period. Additionally, in calculating diluted earnings per share, 5.3 million, 4.2 million and 2.7 million shares related to outstanding stock options and unvested restricted stock awards were excluded for the years ended December 31, 2013, 2012 and 2011, respectively, because they were anti-dilutive.
Recent Accounting Pronouncements	'
	Recent Accounting Pronouncements
	In July 2013, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. 2013-11, Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists (“ASU 2013-11”) to provide guidance on the presentation of unrecognized tax benefits. ASU 2013-11 requires an entity to present an unrecognized tax benefit, or a portion of an unrecognized tax benefit, as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward, except as follows: to the extent a net operating loss carryforward, a similar tax loss, or a tax credit carryforward is not available at the reporting date under the tax law of the applicable jurisdiction to settle any additional income taxes that would result from the disallowance of a tax position or the tax law of the applicable jurisdiction does not require the entity to use, and the entity does not intend to use, the deferred tax asset for such purpose, the unrecognized tax benefit should be presented in the financial statements as a liability and should not be combined with deferred tax assets. ASU 2013-11 is effective for the Company in the first quarter of fiscal 2014 with earlier adoption permitted. ASU 2013-11 should be applied prospectively with retroactive application permitted. The Company is currently evaluating the impact of the pending adoption of ASU 2013-11 on its consolidated financial statements starting in 2014.
	In February 2013, the FASB issued ASU No. 2013-02, Comprehensive Income – Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income, which requires additional disclosure about material changes in the components of accumulated other comprehensive income, including amounts reclassified and amounts due to current period other comprehensive income. The standard was effective in the first quarter of fiscal 2013. The Company has not adopted the disclosure provisions required by this ASU as there are no material components of accumulated other comprehensive income nor have there been any material reclassifications out of accumulated other comprehensive income during the periods ended December 31, 2013, 2012 or 2011.
