Accounting Policies [Abstract]
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. The Company’s critical accounting policies are those that affect its more significant judgments used in the preparation of its consolidated financial statements. A description of the Company’s critical accounting policies and estimates is contained in its Annual Report on Form 10-K for the fiscal year ended December 31, 2018, and in this note to the consolidated financial statements. There were no material changes to the Company’s critical accounting policies and use of estimates during the first nine months of 2019, other than those related to leases resulting from the adoption of a new accounting pronouncement, as described in this Note 2 under “Recently Adopted Accounting Guidance”. Principles of Consolidation The accompanying Consolidated Financial Statements include the accounts of the Company and its wholly-owned subsidiaries, TechTarget Securities Corporation (“TSC”), TechTarget Limited, TechTarget (HK) Limited (“TTGT HK”), TechTarget (Australia) Pty Ltd., TechTarget (Singapore) Pte Ltd., E-Magine Médias SAS (“LeMagIT”) and TechTarget Germany GmbH. TSC is a Massachusetts corporation. TechTarget Limited is a subsidiary doing business principally in the United Kingdom. TTGT HK is a subsidiary incorporated in Hong Kong in order to facilitate the Company’s activities in the Asia-Pacific region. In 2018, TechTarget modified its People’s Republic of China operations consolidating its activities with other TechTarget locations. TechTarget (Beijing) Information Technology Consulting Co. Ltd. (“TTGT Consulting”) and Keji Wangtuo Information Technology Co., Ltd., (“KWIT”), which were incorporated under the laws of the People’s Republic of China (“PRC”), were closed during 2018. TechTarget (Australia) Pty Ltd. and TechTarget (Singapore) Pte Ltd. are the entities through which the Company does business in Australia and Singapore, respectively; LeMagIT and TechTarget Germany GmbH, both wholly-owned subsidiaries of TechTarget Limited, are entities through which the Company does business in France and Germany, respectively. Basis of Presentation The accompanying unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted (Generally Accepted Accounting Principles or “ ” “U.S.” Use of Estimates The preparation of consolidated financial statements in conformity with 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 consolidated 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 revenues, long-lived assets, goodwill, the allowance for doubtful accounts, stock-based compensation, self-insurance accruals, and income taxes. The Company reduces its accounts receivable for an allowance for doubtful accounts based on its best estimate of the amount of probable credit losses. 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 revenues from the sale of targeted marketing and advertising campaigns, which it delivers via its network of websites and data analytics solutions. Revenue is recognized when performance obligations are satisfied by transferring promised goods or services to customers, as determined by applying a five-step process consisting of: a) identifying the contract, or contracts, with a customer, b) identifying the performance obligations in the contract, c) determining the transaction price, d) allocating the transaction price to the performance obligations in the contract, and e) recognizing revenue when, or as, performance obligations are satisfied. Recent Accounting Pronouncements Recently Adopted Accounting Guidance In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) (“ASU 2016-02”). ASU 2016-02 establishes a right-of-use (“ROU”) model that requires a lessee to record a ROU asset and a lease liability on the balance sheet for all leases with terms longer than twelve months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the Consolidated Statements of Income and Comprehensive Income. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. A modified retrospective transition approach is required for lessees, capital and operating leases, existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, with certain practical expedients available. The Company adopted ASU 2016-02 in the first quarter of 2019 using the modified retrospective approach, and elected the package of practical expedients permitted under the transition guidance. Results and disclosure requirements for reporting periods beginning after January 1, 2019 are presented under Topic 842, while prior period amounts have not been adjusted and continue to be reported in accordance with our historical accounting under Topic 840. We elected the package of practical expedients permitted under the transition guidance, which allowed us to carryforward our historical lease classification, our assessment on whether a contract was or contains a lease, and our initial direct costs for any leases that existed prior to January 1, 2019. We also elected to combine our lease and non-lease components and to keep leases with an initial term of 12 months or less off the balance sheet and recognize the associated lease payments in the consolidated statements of income on a straight-line basis over the lease term. The Company recorded operating lease assets with right-of-use of $27.5 million and $2.9 million current operating lease liability and $29.2 million non-current operating lease liability as of January 1, 2019, of which $4.9 million and $0.3 million were reclassified from deferred rent and prepaid rent, respectively. Accounting Guidance Not Yet Adopted In January 2017, the FASB issued ASU No. 2017-04, Intangibles-Goodwill and Other (Topic 350), Simplifying the Test for Goodwill Impairment ("ASU 2017-04"). ASU 2017-04 eliminates the requirement to calculate the implied fair value of goodwill to measure a goodwill impairment charge (step 2 of the goodwill impairment test) and instead requires only a one-step quantitative impairment test, performed by comparing the fair value of goodwill with its carrying amount. ASU 2017-04 is effective on a prospective basis effective for goodwill impairment tests in fiscal years beginning after December 15, 2019. Early adoption is permitted for goodwill impairment tests performed on testing dates after January 1, 2017. The Company is currently evaluating the impact that this standard will have on its consolidated financial statements and disclosures but does not expect that it will have a material impact. In August 2018, the FASB issued ASU No. 2018-15, Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement that is a Service Contract, which requires implementation costs incurred by customers in cloud computing arrangements (i.e., hosting arrangements) to be capitalized under the same premises of authoritative guidance for internal-use software, and deferred over the non-cancellable term of the cloud computing arrangements plus any option renewal periods that are reasonably certain to be exercised by the customer or for which the exercise is controlled by the service provider. ASU 2018-15 is effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years, with early adoption permitted. The Company is currently evaluating the impact of this standard on its consolidated financial statements and disclosures but does not expect that it will have a material impact. In June 2016, the FASB issued ASU 2016-03, “Measurement of Credit Losses on Financial Instruments,” (ASU 2016-03) which amends ASC 326 “Financial Instruments—Credit Losses” which introduces a new methodology for accounting for credit losses on financial instruments. The guidance establishes a new forward looking "expected loss model" that requires entities to estimate current expected credit losses on accounts receivable and financial instruments by using all practical and relevant information. The guidance will be effective for the Company on January 1, 2020. The Company is currently evaluating the impact of this guidance on the consolidated financial statements.

Revenue Recognition [Abstract]
Revenues	3. Revenues Disaggregation of Revenue For the three months ended September 30, For the nine months ended September 30, 2019 2018 2019 2018 North America $ 22,812 $ 20,947 $ 66,444 $ 60,983 International 10,997 9,795 31,623 28,530 Total $ 33,809 $ 30,742 $ 98,067 $ 89,513 The table above depicts the disaggregation of revenue according to categories consistent with how the Company evaluates its financial performance. International revenue consists of international geo-targeted campaigns, which are campaigns targeted at audience members outside of North America. Contract Liabilities Timing may differ between the satisfaction of performance obligations and the invoicing and collection of amounts related to the Company’s contracts with customers. Liabilities are recorded for amounts that are collected in advance of the satisfaction of performance obligations. Additionally, certain customers may receive credits, which are accounted for as a material right. The Company estimates these amounts based on the expected amount of future services to be provided to a customer and allocates a portion of the transaction price to these material rights. The Company recognizes these material rights as the material rights are exercised. The resulting amounts which, are included in the contract liabilities on the accompanying Consolidated Balance Sheets, were $3.0 and $3.5 million at September 30, 2019 and December 31, 2018, respectively. Contract Liabilities Year-to-Date Activity (in thousands) Balance at December 31, 2018 $ 5,573 Deferral of revenue 5,492 Recognition of previously unearned revenue (6,116 ) Balance at September 30, 2019 $ 4,949 The Company elected to apply the following practical expedients: • Existence of a Significant Financing Component in a Contract . As a practical expedient, the Company has not assessed whether a contract has a significant financing component because the Company expects at contract inception that the period between payment by the customer and the transfer of promised goods or services by the Company to the customer will be one year or less. Payment terms and conditions vary by contract type, although terms generally include requirement of payment within 30 to 90 days. In addition, the Company has determined that the payment terms that the Company provides to its customers are structured primarily for reasons other than the provision of financing to the customer. • Costs to Fulfill a Contract . The Company’s revenues are primarily generated from customer contracts that are for one year or less. Costs primarily consist of incentive compensation paid based on the achievements of sales targets in a given period for related revenue streams and are recognized in the month when the revenue is earned. As a practical expedient, for amortization periods which are determined to be one year or less, the Company expenses any incremental costs of obtaining the contract with a customer when incurred. For those customer contracts greater than one year, the Company capitalizes and amortizes the expenses over the period of benefit. • Revenues Invoiced . The Company has applied the practical expedient for certain revenue streams to exclude the value of remaining performance obligations for (i) contracts with an original expected term of one year or less or (ii) contracts for which the Company recognizes revenue in proportion to the amount it has the right to invoice for services performed.

The remaining amortization expense will be recognized over a weighted-average period of approximately 5.03 years. Amortization expense was approximately $50 and $50 for each of the three months ended September 30, 2019 and September 30, 2018, and $0.1 million and $0.1 million for each of the nine months ended September 30, 2019 and September 30, 2018, respectively. Amortization expense is recorded within operating expenses as the intangible assets consist of customer-related assets which generate website traffic that the Company considers to be in support of selling and marketing activities. The Company did not write off any fully amortized intangible assets in the first nine months of 2019 or 2018. The Company expects amortization expense of intangible assets to be as follows: Years Ending December 31: Amortization Expense 2019 (October 1 – December 31) $ 32 2020 110 2021 125 2022 153 2023 37 Thereafter 278 Total $ 735 Goodwill and indefinite-lived intangible assets are not amortized but are reviewed annually for impairment or more frequently if impairment indicators arise.

Lessee Disclosure [Abstract]
Leases and Contingencies	9. Leases and Contingencies On January 1, 2019, the Company adopted ASU 2016-02 using the modified retrospective approach. The Company recorded operating lease assets (right-of-use assets) of $27.5 million and operating lease liabilities of $32.1 million. There was no impact to retained earnings upon adoption of ASU 2016-02. The Company has various non-cancelable lease agreements for certain of its offices with original lease periods expiring between 2019 and 2029. Its lease terms may include options to extend or terminate the lease when it is reasonably certain we will exercise that option. Leases with a renewal option allow the Company to extend the lease term typically between 1 and 5 years. When determining the lease term, renewal options reasonably certain of being exercised are included in the lease term. When determining if a renewal option is reasonably certain of being exercised, the Company considers several economic factors, including but not limited to, the significance of leasehold improvements incurred on the property, whether the asset is difficult to replace, underlying contractual obligations, or specific characteristics unique to that particular lease that would make it reasonably certain that the Company would exercise such option. Renewal and termination options were generally not included in the lease term for the Company's existing operating leases. Certain of the arrangements have discounted rent periods or escalating rent payment provisions. Leases with an initial term of twelve months or less are not recorded on the consolidated balance sheets. The Compnay recognize rent expense on a straight-line basis over the lease term. The Company’s lease agreements do not contain any material residual value guarantee or material restrictive covenants. As of September 30, 2019, operating lease assets were $25.5 million and operating lease liabilities were $29.8 million. The maturity of the Company’s operating lease liabilities as of September 30, 2019 are as follows: Minimum Lease Years Ending December 31: Payments 2019 (September 30, – December 31) $ 595 2020 3,620 2021 3,708 2022 3,397 2023 3,397 Thereafter 21,267 Total future minimum lease payments $ 35,984 Less imputed interest 6,161 Total operating lease liabilities $ 29,823 Included in the condensed consolidated balance sheet: Current operating lease liabilities $ 2,209 Non-current operating lease liabilities 27,614 Total operating lease liabilities $ 29,823 As of September 30, 2019, the Company had entered into a lease that had not yet commenced with future lease payments of $1.5 million which are not reflected in the table above. For the three and nine months ended September 30, 2019, the total lease cost is comprised of the following amounts: Three Months Ended Nine Months Ended Operating lease expense $ 964 $ 2,914 Short-term lease expense 22 64 Total lease expense $ 986 $ 2,978 The following summarizes additional information related to operating leases: As of September 30, 2019 Weighted-average remaining lease term — operating leases 5.6 Weighted-average discount rate — operating leases 4 % If the rate implicit in the lease is not readily determinable, the Company uses its incremental borrowing rate as the discount rate. The Company uses its best judgment when determining the incremental borrowing rate, which is the rate of interest that the Company would have to pay to borrow on a collateralized basis over a similar term to the lease payments in a similar currency. As previously disclosed in our 2018 Annual Report on Form 10-K and under the previous lease accounting standard, ASC 840, Leases Years Ending December 31: Minimum Lease Payments 2019 $ 4,180 2020 3,629 2021 3,721 2022 3,397 2023 3,397 Thereafter 21,267 Total $ 39,591 Total rent expense under the Company’s noncancelable leases was approximately $1 and $3 million for the three and nine months ended September 30, 2018, respectively Litigation From time to time and in the ordinary course of business, the Company may be subject to various claims, charges, and litigation. At September 30, 2019 and December 31, 2018, 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 .

Stock-Based Compensation	10. Stock-Based Compensation Stock Option and Incentive Plans In April 2007, the Board approved the 2007 Stock Option and Incentive Plan (the “2007 Plan”), which was approved by the stockholders of the Company and became effective upon the consummation of the Company’s IPO in May 2007. The 2007 Plan allowed the Company to grant ISOs, NSOs, stock appreciation rights, deferred stock awards, restricted stock units and other awards. Under the 2007 Plan, stock options could not be granted at less than fair market value on the date of grant, and grants generally vested over a three- to four-year period. Stock options granted under the 2007 Plan expire no later than ten years after the grant date. Additionally, beginning with awards made in August 2015, the Company had the option to direct a net issuance of shares for satisfaction of tax liability with respect to vesting of awards and delivery of shares. Prior to August 2015, this choice of settlement method was solely at the discretion of the award recipient. At the inception of the plan, t he Company reserved for issuance an aggregate of 2,911,667 shares of common stock under the 2007 Plan. The 2007 Plan was subject to an automatic annual increase of shares 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 compensation committee of the Board. No new awards may be granted under the 2007 Plan; however, shares of common stock remaining in the 2007 Plan are available for issuance in connection with previously awarded grants under the 2007 Plan. In March 2017, the Board approved the 2017 Stock Option and Incentive Plan (the “2017 Plan”), which was approved by the stockholders of the Company at the 2017 Annual Meeting and became effective June 16, 2017. The 2017 Plan replaces the Company’s 2007 Plan. On that date, 3,000,000 shares of Common Stock were reserved for issuance under the 2017 Plan and, generally, shares that are forfeited or canceled from awards under the 2017 Plan also will be available for future awards. Under the 2017 Plan, the Company may grant restricted stock and restricted stock units, non-qualified stock options, stock appreciation rights, performance awards, and other stock-based and cash-based awards. Grants generally vest in equal tranches over a three-year period. Stock options granted under the 2017 Plan expire no later than ten years after the grant date. Shares of stock issued pursuant to restricted stock awards are restricted in that they are not transferable until they vest. Stock underlying awards of restricted stock units are not issued until the units vest. Non-qualified stock options cannot be exercised until they vest. Under the 2017 Plan, all stock options and stock appreciation rights must be granted with an exercise price that is at least equal to the fair market value of the stock on the date of grant. The 2017 Plan broadly prohibits the repricing of options and stock appreciation rights without stockholder approval and requires that no dividends or dividend equivalents be paid with respect to options or stock appreciation rights. The 2017 Plan further provides that, in the event any dividends or dividend equivalents are declared with respect to restricted stock, restricted stock units, other stock-based awards and performance awards (referred to as “full-value awards”), they would be subject to the same vesting and forfeiture provisions as the underlying award. There is a total of 1,385,130 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 expected volatility of options granted 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. The expected life of options has been determined utilizing the “simplified” method. The risk-free interest rate is based on a zero coupon U.S. 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 historical averages in determining the expense recorded in each period.

TSC is a Massachusetts corporation. TechTarget Limited is a subsidiary doing business principally in the United Kingdom. TTGT HK is a subsidiary incorporated in Hong Kong in order to facilitate the Company’s activities in the Asia-Pacific region. In 2018, TechTarget modified its People’s Republic of China operations consolidating its activities with other TechTarget locations. TechTarget (Beijing) Information Technology Consulting Co. Ltd. (“TTGT Consulting”) and Keji Wangtuo Information Technology Co., Ltd., (“KWIT”), which were incorporated under the laws of the People’s Republic of China (“PRC”), were closed during 2018. TechTarget (Australia) Pty Ltd. and TechTarget (Singapore) Pte Ltd. are the entities through which the Company does business in Australia and Singapore, respectively; LeMagIT and TechTarget Germany GmbH, both wholly-owned subsidiaries of TechTarget Limited, are entities through which the Company does business in France and Germany, respectively.
Basis of Presentation	Basis of Presentation The accompanying unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted (Generally Accepted Accounting Principles or “ ” “U.S.”
Use of Estimates	Use of Estimates The preparation of consolidated financial statements in conformity with 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 consolidated 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 revenues, long-lived assets, goodwill, the allowance for doubtful accounts, stock-based compensation, self-insurance accruals, and income taxes. The Company reduces its accounts receivable for an allowance for doubtful accounts based on its best estimate of the amount of probable credit losses. 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 revenues from the sale of targeted marketing and advertising campaigns, which it delivers via its network of websites and data analytics solutions. Revenue is recognized when performance obligations are satisfied by transferring promised goods or services to customers, as determined by applying a five-step process consisting of: a) identifying the contract, or contracts, with a customer, b) identifying the performance obligations in the contract, c) determining the transaction price, d) allocating the transaction price to the performance obligations in the contract, and e) recognizing revenue when, or as, performance obligations are satisfied.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Recently Adopted Accounting Guidance In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) (“ASU 2016-02”). ASU 2016-02 establishes a right-of-use (“ROU”) model that requires a lessee to record a ROU asset and a lease liability on the balance sheet for all leases with terms longer than twelve months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the Consolidated Statements of Income and Comprehensive Income. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. A modified retrospective transition approach is required for lessees, capital and operating leases, existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, with certain practical expedients available. The Company adopted ASU 2016-02 in the first quarter of 2019 using the modified retrospective approach, and elected the package of practical expedients permitted under the transition guidance. Results and disclosure requirements for reporting periods beginning after January 1, 2019 are presented under Topic 842, while prior period amounts have not been adjusted and continue to be reported in accordance with our historical accounting under Topic 840. We elected the package of practical expedients permitted under the transition guidance, which allowed us to carryforward our historical lease classification, our assessment on whether a contract was or contains a lease, and our initial direct costs for any leases that existed prior to January 1, 2019. We also elected to combine our lease and non-lease components and to keep leases with an initial term of 12 months or less off the balance sheet and recognize the associated lease payments in the consolidated statements of income on a straight-line basis over the lease term. The Company recorded operating lease assets with right-of-use of $27.5 million and $2.9 million current operating lease liability and $29.2 million non-current operating lease liability as of January 1, 2019, of which $4.9 million and $0.3 million were reclassified from deferred rent and prepaid rent, respectively. Accounting Guidance Not Yet Adopted In January 2017, the FASB issued ASU No. 2017-04, Intangibles-Goodwill and Other (Topic 350), Simplifying the Test for Goodwill Impairment ("ASU 2017-04"). ASU 2017-04 eliminates the requirement to calculate the implied fair value of goodwill to measure a goodwill impairment charge (step 2 of the goodwill impairment test) and instead requires only a one-step quantitative impairment test, performed by comparing the fair value of goodwill with its carrying amount. ASU 2017-04 is effective on a prospective basis effective for goodwill impairment tests in fiscal years beginning after December 15, 2019. Early adoption is permitted for goodwill impairment tests performed on testing dates after January 1, 2017. The Company is currently evaluating the impact that this standard will have on its consolidated financial statements and disclosures but does not expect that it will have a material impact. In August 2018, the FASB issued ASU No. 2018-15, Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement that is a Service Contract, which requires implementation costs incurred by customers in cloud computing arrangements (i.e., hosting arrangements) to be capitalized under the same premises of authoritative guidance for internal-use software, and deferred over the non-cancellable term of the cloud computing arrangements plus any option renewal periods that are reasonably certain to be exercised by the customer or for which the exercise is controlled by the service provider. ASU 2018-15 is effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years, with early adoption permitted. The Company is currently evaluating the impact of this standard on its consolidated financial statements and disclosures but does not expect that it will have a material impact. In June 2016, the FASB issued ASU 2016-03, “Measurement of Credit Losses on Financial Instruments,” (ASU 2016-03) which amends ASC 326 “Financial Instruments—Credit Losses” which introduces a new methodology for accounting for credit losses on financial instruments. The guidance establishes a new forward looking "expected loss model" that requires entities to estimate current expected credit losses on accounts receivable and financial instruments by using all practical and relevant information. The guidance will be effective for the Company on January 1, 2020. The Company is currently evaluating the impact of this guidance on the consolidated financial statements.
