Accounting Policies [Abstract]
Summary of Business and Significant Accounting Policies	1. Summary of Business and Significant Accounting Policies Marin Software Incorporated (the “Company”) was incorporated in Delaware in March 2006. The Company provides a leading cross-channel, cross-device, enterprise marketing software platform for search, display and social advertising channels, offered as an integrated software-as-a-service, or SaaS, solution for advertisers and agencies. The Company’s platform enables digital marketers to improve financial performance, realize efficiencies and time savings, and make better business decisions. The Company’s corporate headquarters are located in San Francisco, California, and the Company has additional offices in the following locations: Austin, Chicago, Dublin, Hamburg, London, New York, Paris, Portland, Shanghai, Sydney and Tokyo. Basis of Presentation and Consolidation The accompanying unaudited condensed consolidated financial statements and condensed footnotes have been prepared in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by United States generally accepted accounting principles (“GAAP”) for complete financial statements. In the opinion of management, all adjustments, consisting of only normal recurring items, considered necessary for fair statement have been included. The results of operations for the three and six months ended June 30, 2016, are not necessarily indicative of the results to be expected for the year ending December 31, 2016, or for other interim periods or for future years. The accompanying unaudited condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated on consolidation. The condensed consolidated balance sheet as of December 31, 2015, is derived from audited financial statements as of that date but does not include all of the information and footnotes required by GAAP for complete financial statements. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2015 filed with the Securities and Exchange Commission (“SEC”) on February 22, 2016. Fair Value Measurements The Company’s financial instruments, including cash equivalents, accounts receivable, accounts payable and accrued expenses are carried at cost, which approximates fair value because of the short-term nature of those instruments. Based on borrowing rates available to the Company for loans with similar terms and maturities, and in consideration of the Company’s credit risk profile, the carrying value of borrowings (Note 6) approximates fair value (level 2 within the fair value hierarchy). Cash equivalents consist of money market funds, which are readily convertible into cash and have original maturity dates of less than three months from the date of their respective purchases. These money market funds presented as cash equivalents on the consolidated balance sheets are classified as level 1 within the fair value hierarchy, and totaled $23,612 and $25,564 as of June 30, 2016 and December 31, 2015, respectively. Allowance for Doubtful Accounts and Revenue Credits The allowance for doubtful accounts reflects the Company’s best estimate of probable losses inherent in the Company’s receivables portfolio determined on the basis of historical experience, specific allowances for known troubled accounts and other currently available evidence. The Company has not historically experienced significant credit losses from its accounts receivable. The Company performs a regular review of its customers’ payment histories and associated credit risks and it does not require collateral from its customers. Certain contracts with advertising agencies contain sequential liability provisions, whereby the agency does not have an obligation to pay the Company until payment is received from the agency’s customers. In these circumstances, the Company evaluates the credit worthiness of the agency’s customers, in addition to the agency itself. As of June 30, 2016 and December 31, 2015, the Company recorded an allowance for doubtful accounts in the amount of $1,987 and $2,188, respectively. From time to time, the Company provides credits to customers and an allowance is made based on historical credit activity. As of June 30, 2016, and December 31, 2015, the Company recorded an allowance for potential customer credits in the amount of $1,663 and $2,274, respectively. Goodwill and Intangible Assets Goodwill represents the excess of the purchase price in a business combination over the fair value of net tangible and intangible assets acquired. Intangible assets that are not considered to have an indefinite useful life are amortized over their useful lives, which generally range from two to six years. Estimated remaining useful lives of purchased intangible assets are evaluated to assess whether events or changes in circumstances warrant a revision to the remaining periods of amortization. In addition, we evaluate our goodwill for impairment at least annually in the fourth quarter, or more frequently if events or changes in circumstances indicate that these assets may be impaired. No goodwill impairment has been identified in any of the periods presented. Revenue Recognition The Company generates revenues principally from subscriptions either directly with advertisers or with advertising agencies to its platform for the management of search, social and display advertising. The Company’s search subscription agreements are generally one year or longer in length. The Company’s subscription fee under most contracts is variable based on the value of the advertising spend that the Company’s advertisers manage through the Company’s platform and is generally invoiced on a monthly basis. Contracts with direct advertisers and certain contracts with advertising agencies also include a minimum monthly fee that is payable over the duration of the contract. The Company’s customers do not have the right to take possession of the software supporting the application service at any time, nor do the arrangements contain general rights of return. The Company commences revenue recognition for both direct advertisers and advertising agencies when all of the following conditions are met: · persuasive evidence of an arrangement exists; · the Company’s platform is made available to the customer; · the fee is fixed or determinable; and · collection is reasonably assured. The Company recognizes the total minimum fee for both direct advertisers and advertising agencies, where applicable, over the duration of the contract, commencing on the date that the Company’s platform is made available to the customer, provided revenues recognized do not exceed amounts that are invoiced and due. The variable fee, which is based on a percentage of the value of the advertising spend managed through the Company’s platform, is recognized once the amount is fixed or determinable, which is generally on a monthly basis concurrent with the issuance of the customer invoice. Signed contracts are used as evidence of an arrangement. The Company assesses collectability based on a number of factors such as past collection history with the customer and creditworthiness of the customer. Certain agreements with advertising agencies also contain sequential liability provisions, which provide that the agency has no obligation to pay the Company until the agency receives payment from its customers. In these circumstances, the Company evaluates the credit worthiness of the agency’s customers, in addition to the agency itself, to conclude whether or not collectability is reasonably assured. If the Company determines collectability is not reasonably assured, the Company defers the revenue recognition until collectability becomes reasonably assured. The Company applies the authoritative accounting guidance regarding revenue recognition for arrangements with multiple deliverables. Professional services and training, when sold with the Company’s platform subscription services, are accounted for separately when those services have standalone value. In determining whether professional services and training services can be accounted for separately from subscription services, the Company considers the following factors: availability of the services from other vendors; the nature of the services; the dependence of the subscription services on the customer’s decision to buy the professional services; and whether the Company sells the Company’s subscription services without professional services. If the deliverables have stand-alone value, the Company accounts for each deliverable separately and revenues are recognized for the respective deliverables as they are delivered. If one or more of the deliverables do not have stand-alone value, the deliverables that do not have stand-alone value are combined with the final deliverables within the arrangement and treated as a single unit of accounting. Revenues for arrangements treated as a single unit of accounting are recognized over the period of the contract commencing upon delivery of the final deliverable. As of June 30, 2016, the Company did not have stand-alone value for the professional services and training services. This is because the Company includes professional services and training services with the Company’s subscription services and those services are not available from other vendors. Cost of Revenues Cost of revenues primarily consists of costs related to hosting the Company’s enterprise marketing software platform, providing implementation and ongoing customer support, data communications expenses, salaries and benefits of operations and support personnel, software license fees, costs associated with website development activities, indirect overhead, amortization expense associated with capitalized internally developed software and intangible assets and property and equipment depreciation. Recent Accounting Pronouncements In March 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-09, C ompensation - Stock Compensation: Improvements to Employee Share-Based Payment Accounting In March 2016, the FASB issued ASU 2016-08, Revenue from Contracts with Customers This guidance will be effective for the Company in the first quarter of its fiscal year ending December 31, 2017. The Company is currently evaluating the impact of the adoption of this ASU on the consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, Leases comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. The amendments in this update are effective for annual periods beginning after December 15, 2018 and interim periods therein, and must be adopted using a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the consolidated financial statements. The Company is currently evaluating the impact the adoption of this standard will have on the consolidated financial statements. In September 2015, the FASB issued ASU 2015-16, Business Combinations In August 2014, the FASB issued ASU 2014-15, Disclosures of Uncertainties About an Entity’s Ability to Continue as a Going Concern In June 2014, the FASB issued ASU 2014-12, Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers

Business Combinations [Abstract]
Business Combinations	2. Business Combination On February 12, 2015, pursuant to the terms of a Share Purchase Agreement, the Company acquired all outstanding shares of capital stock of SocialMoov S.A.S. (“SocialMoov”), with SocialMoov surviving as a wholly-owned subsidiary of the Company. Based in Paris, France, SocialMoov is a provider of social advertising tools for advertisers and agencies. The total purchase price for the acquisition was $13,288, which consisted of 636 shares of the Company’s common stock valued at $4,337 upon the closing date using the weighted average of the Company’s closing date stock price for a short period of time preceding the closing date of the acquisition, $8,858 in cash paid at the acquisition date and $93 in cash paid as contingent consideration during the first quarter of 2016. Of the cash consideration paid at the closing date, $1,894 is held in escrow to secure indemnification obligations of the shareholders of SocialMoov to the Company following the closing, which has not been released as of the filing date of this Quarterly Report on Form 10-Q. In addition, the Company agreed to issue 927 shares of common stock at future dates as defined in the Share Purchase Agreement, valued at $6,487 upon the closing date of the acquisition using the Company’s closing date stock price immediately preceding the acquisition, to existing employee shareholders of SocialMoov in connection with the acquisition, which are conditioned upon such employees’ continuous employment with the Company. These shares have been excluded from the purchase consideration and are being recognized as post-acquisition stock-based compensation expense over the employees’ requisite service periods. In February 2016, the Company issued 463 of these shares. The Company also granted RSUs representing 219 shares of common stock, valued at $959 using the Company’s grant date stock price, with time-based vesting to employees of SocialMoov that continued employment with SocialMoov subsequent to the acquisition. The Company recognizes compensation expense equal to the grant date fair value of the common stock or stock-based awards on a straight-line basis over the employee’s requisite service period. The results of operations and the fair values of the assets acquired and liabilities assumed have been included in the accompanying unaudited condensed financial statements since the acquisition date. The following table summarizes the fair values of tangible assets acquired, liabilities assumed, intangible assets and residual goodwill from the acquisition of SocialMoov (in thousands except years): Estimated Estimated Fair Value Useful Life Tangible assets acquired $ 2,641 N/A Liabilities assumed (3,476 ) N/A Developed technology 3,800 5 years Customer relationships 2,080 4 years Tradename 260 3 years Goodwill 7,983 Indefinite Total purchase price $ 13,288 The goodwill is primarily attributable to synergies expected to arise from the acquisition, and is not expected to be deductible for tax purposes. The values assigned to the intangible assets are based on a third-party valuation analysis, which includes estimates and judgments regarding expectations for the success and life cycles of the solutions and technologies acquired.

Restructuring Activities	3. Restructuring Activities 2016 Restructuring Plan During the second quarter of 2016, the Company executed an additional organizational restructuring (the “2016 Restructuring Plan”) primarily to improve cost efficiencies and effectiveness in sales. The total estimated restructuring related expenses associated with the 2016 Restructuring Plan, consisting primarily of severance costs, are $473, and will be recorded to cost of revenues or operating expenses, as applicable, within the Company’s condensed consolidated statements of operations as they are incurred. The Company recorded $425 of restructuring related expenses in connection with the 2016 Restructuring Plans for the three and six months ended June 30, 2016, and the Company expects to incur and pay the majority of the estimated remaining amount of $48 by the end of fiscal 2016. As of June 30, 2016, approximately $394 in restructuring related expenses associated with the 2016 Restructuring Plans remained unpaid and were included primarily in accrued expenses and other current liabilities on the Company’s condensed consolidated balance sheets. 2015 Restructuring Plans During the third and fourth quarters of 2015, the Company executed organizational restructurings (the “2015 Restructuring Plans”) in order to improve cost efficiencies and realign its sales, customer success and marketing operations. Actions pursuant to the 2015 Restructuring Plans were substantially complete as of December 31, 2015, and the associated costs were not material for the three and six months ended June 30, 2016.

Debt Disclosure [Abstract]
Debt	6. Debt Capital Lease Arrangements Since 2013, the Company has entered into capital lease arrangements with an equipment manufacturer to finance acquisitions of computer equipment. These leases have effective annual interest rates ranging from 5.8% to 6.0%, and carry terms of between 36 to 48 months. At the end of the lease periods, the Company has the option to purchase the underlying equipment at the estimated fair market value, or for a nominal amount in some cases. As of June 30, 2016 and December 31, 2015, the net book value of the equipment under these capital leases was $2,092 and $2,446, respectively, and the remaining principal balance payable was $2,333 and $2,700, respectively. Revolving Credit Facility In July 2015, the Company entered into an amendment to its existing loan and security agreement pursuant to which Silicon Valley Bank agreed to increase the revolving credit facility of up to the lesser of $20,000 or 80% of the Company’s eligible accounts receivable. Also, the expiration date of the revolving credit facility was extended to July 31, 2017, and the annual interest rate was amended to (a) the prime rate or (b) the London interbank offered rate then in effect, plus a margin of 2.75%, payable on a monthly basis. The amendment contains affirmative and negative covenants, including covenants related to the delivery of financial and other information, the maintenance of certain financial covenants, as well as limitations on dispositions, changes in business or management, mergers or consolidations, dividends and other corporate actions.

Equity Award Plans	8. Equity Award Plans In April 2006, the Company’s Board of Directors (the “Board”) adopted and the stockholders approved the 2006 Stock Option Plan (“2006 Plan”). The 2006 Plan provides for the grant of incentive stock options under the federal tax laws and non-statutory stock options. Only employees may receive incentive stock options, but non-statutory stock options may be granted to employees, non-employee directors and consultants. The stock options are exercisable at a price equal to the market value of the underlying shares of common stock on the date of the grant as determined by the Board. The term of options granted under the 2006 Plan may not exceed ten years. Certain options are eligible for exercise prior to vesting. Exercised but unvested shares of common stock are subject to repurchase by the Company at the initial exercise price. The proceeds from the shares of common stock subject to repurchase are classified as a liability and reclassified to equity as the shares vest. Under the 2006 Plan’s early exercise feature, the Company had the right to repurchase 5 and 18 shares of common stock as of June 30, 2016, and December 31, 2015, respectively. The Company records cash received from the exercise of unvested stock options as a long-term liability, as well as the fair value of vested outstanding options to non-employee consultants. As of June 30, 2016, and December 31, 2015, $46 and $249, respectively, has been recorded as a long-term liability on the accompanying unaudited condensed consolidated balance sheets. In February 2013, the Board and stockholders approved the 2013 Equity Incentive Plan (“2013 Plan”), under which 4,500 shares of common stock were originally reserved for issuance. Additionally, all reserved and unissued shares under the 2006 Plan at the time the 2013 Plan became effective are eligible for issuance under the 2013 Plan. The 2013 Plan became effective on March 21, 2013, at which time the Company ceased to grant equity awards under the 2006 Plan. The 2013 Plan authorizes the award of stock options, restricted stock awards, stock appreciation rights, RSUs, performance awards and stock bonuses to the Company’s employees, directors, consultants, independent contractors and advisors. On January 1 of each of the first ten calendar years through 2023, the number of shares of common stock reserved under the 2013 Plan will automatically increase by an amount equal to 5% of the total outstanding shares as of immediately preceding December 31, or such lesser number of shares as determined by the Board. Pursuant to terms of the 2013 Plan, the shares available for issuance increased by approximately 1,878 shares of common stock on January 1, 2016. Stock Options A summary of stock option activity under the 2006 Plan and 2013 Plan is as follows: Options Outstanding Weighted Average Weighted Remaining Average Contractual Aggregate Number of Exercise Term Intrinsic Shares Price Per Share (in Years) Value Balances at December 31, 2015 5,960 $ 7.58 7.85 $ 957 Options granted 862 2.74 9.77 Options exercised (77 ) 2.45 — Options forfeited and cancelled (401 ) 8.81 — Balances at June 30, 2016 6,344 $ 6.91 7.57 $ 433 Options exercisable 3,272 $ 7.79 6.31 $ 349 Options vested 3,246 $ 7.76 6.36 $ 349 Options vested and expected to vest 6,086 $ 6.96 7.51 $ 428 RSUs A summary of RSUs granted and unvested under the 2013 Plan is as follows: RSUs Outstanding Weighted Number of Grant Date Shares Fair Value Per Unit Granted and unvested at December 31, 2015 1,221 $ 9.36 RSUs granted 1,382 3.25 RSUs vested (173 ) 7.45 RSUs cancelled and withheld to cover taxes (455 ) 5.91 Granted and unvested at June 30, 2016 1,975 $ 4.27 Employee Stock Purchase Plan In February 2013, the Board and stockholders approved the 2013 Employee Stock Purchase Plan (“2013 ESPP”), under which 1,000 shares of common stock were originally reserved for issuance. The 2013 ESPP became effective on March 22, 2013. The 2013 ESPP provides generally for six-month purchase periods and the purchase price for shares of common stock purchased under the 2013 ESPP will be 85% of the lesser of the fair market value of the common stock on (i) the first trading day of the applicable offering period and (ii) the last trading day of each purchase period in the applicable offering period. On January 1 of each of the first 10 calendar years following the first offering date, the number of shares reserved under the 2013 ESPP will automatically increase by an amount equal to 1% of the total outstanding shares as of immediately preceding December 31, but not to exceed 700 shares. Pursuant to terms of the 2013 ESPP, the shares available for issuance increased by approximately 376 shares on January 1, 2016. During the three and six months ended June 30, 2016, 175 shares were issued under the 2013 ESPP. During the three and six months ended June 30, 2015, 105 shares were issued under the 2013 ESPP.

Stock-Based Compensation	9. Stock-Based Compensation For stock-based awards granted by the Company, stock-based compensation expense is measured at grant date based on the fair value of the award and is expensed over the requisite service period. The Company recorded stock-based compensation of $2,939 and $4,939 for the three months ended June 30, 2016 and 2015, respectively, and $6,761 and $8,434 for the six months ended June 30, 2016 and 2015, respectively. Stock Options The Company uses the Black-Scholes option pricing model to estimate the fair value of options. This model requires the input of highly subjective assumptions including the expected volatility, risk-free interest rate and the expected life of options. The Company used the following assumptions: Three Months Ended June 30, Six Months Ended June 30, 2016 2015 2016 2015 Dividend yield — — — — Expected volatility 47.6 % 48.0 % 47.5 % 50.4 % Risk-free interest rate 1.34 % 1.58 % 1.44 % 1.73 % Expected life of options (in years) 6.25 6.25 6.25 6.25 Forfeiture rate 7.0 % 7.0 % 7.0 % 7.0 % As the Company has limited historical option exercise data, the expected term of the stock options granted to employees was calculated based on the simplified method. Under the simplified method, the expected term is equal to the average of an option’s weighted-average vesting period and its contractual term. Pursuant to the SEC Staff Accounting Bulletin (“SAB”) No. 110, the Company will continue to use the simplified method until sufficient information regarding exercise behavior, such as historical exercise data or exercise information from external sources, becomes available. The Company estimates the expected volatility of its common stock on the date of grant based on the historical stock volatilities of similar publicly-traded entities over a period equal to the expected terms of the options, as the Company does not have sufficient trading history to use the volatility of its own common stock. The Company has no history or expectation of paying cash dividends on its common stock. The risk-free interest rate is based on the United States Treasury yield for a term consistent with the expected life of the options in effect at the time of grant. Cash proceeds from the exercise of stock options were $189 and $1,028 during the six months ended June 30, 2016 and 2015, respectively. Compensation expense is recognized ratably over the requisite service period. As of June 30, 2016, there was $ 8,082 Restricted Stock and RSUs As of June 30, 2016, there was $ 8,857 2.6 Employee Stock Purchase Plan The Company estimates the fair value of purchase rights under the 2013 ESPP using the Black-Scholes valuation model. The fair value of each purchase right under the 2013 ESPP was estimated on the date of grant using the Black-Scholes option valuation model and the straight-line attribution approach with assumptions substantially similar to those used for the valuation of our stock option awards.

Income Tax Disclosure [Abstract]
Income Taxes	10. Income Taxes The Company’s quarterly provision for income taxes is based on an estimated effective annual income tax rate. The Company’s quarterly provision for income taxes also includes the tax impact of certain unusual or infrequently occurring items, if any, including changes in judgment about valuation allowances and effects of changes in tax laws or rates, in the interim period in which they occur. Income tax expense for the three and six months ended June 30, 2016, was $307 and $648, respectively, on pre-tax losses of $4,111 and $8,183, respectively. For the three and six months ended June 30, 2015, the Company recognized income tax expense of $138 and $374, respectively, on pre-tax losses of $11,909 and $21,333, respectively. As of June 30, 2016, the income tax rate varies from the United States statutory income tax rate primarily due to valuation allowances in the United States and taxable income generated by the Company’s foreign wholly-owned subsidiaries. The Company reviews the likelihood that it will realize the benefit of its deferred tax assets and, therefore, the need for valuation allowances on a quarterly basis. There is no corresponding income tax benefit recognized with respect to losses incurred and no corresponding income tax expense recognized with respect to earnings generated in jurisdictions with a valuation allowance. This causes variability in the Company’s effective tax rate. The Company will maintain the valuation allowances until it is more likely than not that the net deferred tax assets will be realized. Tax positions taken by the Company are subject to audits by multiple tax jurisdictions. The Company accounts for uncertain tax positions and believes that it has provided adequate reserves for its unrecognized tax benefits for all tax years still open for assessment. The Company also believes that it does not have any tax position for which it is not reasonably possible that the total amounts of unrecognized tax benefits will significantly increase or decrease within the next year. There were no interest or penalties associated with uncertain tax positions included within the income tax expense balance for the three and six months ended June 30, 2016 and 2015.

Earnings Per Share [Abstract]
Net Loss Per Share Available to Common Stockholders	11. Net Loss Per Share Available to Common Stockholders Basic net loss per share available to common stockholders is calculated by dividing the net loss available to common stockholders by the weighted-average number of shares of common stock outstanding for the period. The weighted-average number of shares of common stock used to calculate the Company’s basic net loss per share available to common stockholders excludes those shares subject to repurchase related to unvested common shares, stock options that were exercised prior to vesting, restricted stock issued and RSUs settled for shares of common stock, as these shares are not deemed to be outstanding for accounting purposes until they vest. The diluted net loss per share of common stock is computed by dividing the net loss using the weighted-average number of shares of common stock, excluding common stock subject to repurchase, and, if dilutive, potential shares of common stock outstanding during the period. Potential shares of common stock consist of common stock subject to repurchase, stock options to purchase common stock, restricted common stock issued and RSUs settled for shares of common stock. The following table presents the calculation of basic and diluted net loss per share: Three Months Ended June 30, Six Months Ended June 30, 2016 2015 2016 2015 Numerator: Net loss available to common stockholders $ (4,418 ) $ (12,047 ) $ (8,831 ) $ (21,707 ) Denominator: Weighted average number of shares, basic and diluted 38,280 36,389 38,023 36,028 Net loss per share available to common stockholders Basic and diluted net loss per common share available to common stockholders $ (0.12 ) $ (0.33 ) $ (0.23 ) $ (0.60 ) The following table presents the potential shares of common stock outstanding that were excluded from the computation of diluted net loss per share available to common stockholders for the periods presented because including them would have been anti-dilutive: Three and Six Months Ended June 30, 2016 2015 Options to purchase common stock 6,344 6,951 Restricted stock units 1,975 1,206 Restricted common stock issued 5 316 Common stock subject to repurchase 5 38 Total 8,329 8,511

Future minimum lease payments for significant operating leases, net of sublease payments from a portion of the Company’s San Francisco and Portland office space, as of June 30, 2016, were as follows: Remaining six months of 2016 $ 3,161 Year ending December 31, 2017 6,202 Year ending December 31, 2018 4,533 Year ending December 31, 2019 4,074 Year ending December 31, 2020 and thereafter 9,396 $ 27,366 Legal Matters From time to time, the Company may be involved in lawsuits, claims, investigations and proceedings, consisting of intellectual property, commercial, employment and other matters, which arise in the ordinary course of business. In accordance with GAAP, the Company records a liability when it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated. These provisions are reviewed at least quarterly and adjusted to reflect the impact of negotiations, settlements, ruling, advice of legal counsel and other information and events pertaining to a particular case. Litigation is inherently unpredictable. If any unfavorable ruling was to occur in any specific period or if a loss becomes probable and estimable, there exists the possibility of a material adverse impact on the Company’s results of operations, financial position or cash flows. Indemnification The Company enters into standard indemnification agreements in the ordinary course of business. Pursuant to the agreements, each party may indemnify, defend and hold the other party harmless with respect to such claim, suit or proceeding brought against it by a third party alleging that the indemnifying party’s intellectual property infringes upon the intellectual property of the third party, or results from a breach of the indemnifying party’s representations and warranties or covenants, or that results from any acts of negligence or willful misconduct. The term of these indemnification agreements is generally perpetual any time after execution of the agreement. The maximum potential amount of future payments the Company could be required to make under these indemnification agreements is unlimited. Historically, the Company has not been obligated to make significant payments for these obligations and no liabilities have been recorded for these obligations on the unaudited consolidated condensed balance sheets as of June 30, 2016 and audited consolidated balance sheets as of December 31, 2015. The Company also indemnifies its officers and directors for certain events or occurrences, subject to certain limits, while the officer or director is or was serving at the Company’s request in such capacity. The maximum amount of potential future indemnification is unlimited; however, the Company has a Directors and Officers insurance policy that limits its exposure and enables the Company to recover a portion of any future amounts paid. Historically, the Company has not been obligated to make any payments for these obligations and no liabilities have been recorded for these obligations on the unaudited consolidated condensed balance sheets as of June 30, 2016 and audited consolidated balance sheets as of December 31, 2015. Other Contingencies The Company is subject to claims and assessments from time to time in the ordinary course of business. The Company’s management does not believe that any such matters, individually or in the aggregate, will have a material adverse effect on the Company’s financial position, results of operations or cash flows.

Basis of Presentation and Consolidation	Basis of Presentation and Consolidation The accompanying unaudited condensed consolidated financial statements and condensed footnotes have been prepared in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by United States generally accepted accounting principles (“GAAP”) for complete financial statements. In the opinion of management, all adjustments, consisting of only normal recurring items, considered necessary for fair statement have been included. The results of operations for the three and six months ended June 30, 2016, are not necessarily indicative of the results to be expected for the year ending December 31, 2016, or for other interim periods or for future years. The accompanying unaudited condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated on consolidation. The condensed consolidated balance sheet as of December 31, 2015, is derived from audited financial statements as of that date but does not include all of the information and footnotes required by GAAP for complete financial statements. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2015 filed with the Securities and Exchange Commission (“SEC”) on February 22, 2016.
Fair Value Measurements	Fair Value Measurements The Company’s financial instruments, including cash equivalents, accounts receivable, accounts payable and accrued expenses are carried at cost, which approximates fair value because of the short-term nature of those instruments. Based on borrowing rates available to the Company for loans with similar terms and maturities, and in consideration of the Company’s credit risk profile, the carrying value of borrowings (Note 6) approximates fair value (level 2 within the fair value hierarchy). Cash equivalents consist of money market funds, which are readily convertible into cash and have original maturity dates of less than three months from the date of their respective purchases. These money market funds presented as cash equivalents on the consolidated balance sheets are classified as level 1 within the fair value hierarchy, and totaled $23,612 and $25,564 as of June 30, 2016 and December 31, 2015, respectively.
Allowance for Doubtful Accounts and Revenue Credits	Allowance for Doubtful Accounts and Revenue Credits The allowance for doubtful accounts reflects the Company’s best estimate of probable losses inherent in the Company’s receivables portfolio determined on the basis of historical experience, specific allowances for known troubled accounts and other currently available evidence. The Company has not historically experienced significant credit losses from its accounts receivable. The Company performs a regular review of its customers’ payment histories and associated credit risks and it does not require collateral from its customers. Certain contracts with advertising agencies contain sequential liability provisions, whereby the agency does not have an obligation to pay the Company until payment is received from the agency’s customers. In these circumstances, the Company evaluates the credit worthiness of the agency’s customers, in addition to the agency itself. As of June 30, 2016 and December 31, 2015, the Company recorded an allowance for doubtful accounts in the amount of $1,987 and $2,188, respectively. From time to time, the Company provides credits to customers and an allowance is made based on historical credit activity. As of June 30, 2016, and December 31, 2015, the Company recorded an allowance for potential customer credits in the amount of $1,663 and $2,274, respectively.
Goodwill and Intangible Assets	Goodwill and Intangible Assets Goodwill represents the excess of the purchase price in a business combination over the fair value of net tangible and intangible assets acquired. Intangible assets that are not considered to have an indefinite useful life are amortized over their useful lives, which generally range from two to six years. Estimated remaining useful lives of purchased intangible assets are evaluated to assess whether events or changes in circumstances warrant a revision to the remaining periods of amortization. In addition, we evaluate our goodwill for impairment at least annually in the fourth quarter, or more frequently if events or changes in circumstances indicate that these assets may be impaired. No goodwill impairment has been identified in any of the periods presented.
Revenue Recognition	Revenue Recognition The Company generates revenues principally from subscriptions either directly with advertisers or with advertising agencies to its platform for the management of search, social and display advertising. The Company’s search subscription agreements are generally one year or longer in length. The Company’s subscription fee under most contracts is variable based on the value of the advertising spend that the Company’s advertisers manage through the Company’s platform and is generally invoiced on a monthly basis. Contracts with direct advertisers and certain contracts with advertising agencies also include a minimum monthly fee that is payable over the duration of the contract. The Company’s customers do not have the right to take possession of the software supporting the application service at any time, nor do the arrangements contain general rights of return. The Company commences revenue recognition for both direct advertisers and advertising agencies when all of the following conditions are met: · persuasive evidence of an arrangement exists; · the Company’s platform is made available to the customer; · the fee is fixed or determinable; and · collection is reasonably assured. The Company recognizes the total minimum fee for both direct advertisers and advertising agencies, where applicable, over the duration of the contract, commencing on the date that the Company’s platform is made available to the customer, provided revenues recognized do not exceed amounts that are invoiced and due. The variable fee, which is based on a percentage of the value of the advertising spend managed through the Company’s platform, is recognized once the amount is fixed or determinable, which is generally on a monthly basis concurrent with the issuance of the customer invoice. Signed contracts are used as evidence of an arrangement. The Company assesses collectability based on a number of factors such as past collection history with the customer and creditworthiness of the customer. Certain agreements with advertising agencies also contain sequential liability provisions, which provide that the agency has no obligation to pay the Company until the agency receives payment from its customers. In these circumstances, the Company evaluates the credit worthiness of the agency’s customers, in addition to the agency itself, to conclude whether or not collectability is reasonably assured. If the Company determines collectability is not reasonably assured, the Company defers the revenue recognition until collectability becomes reasonably assured. The Company applies the authoritative accounting guidance regarding revenue recognition for arrangements with multiple deliverables. Professional services and training, when sold with the Company’s platform subscription services, are accounted for separately when those services have standalone value. In determining whether professional services and training services can be accounted for separately from subscription services, the Company considers the following factors: availability of the services from other vendors; the nature of the services; the dependence of the subscription services on the customer’s decision to buy the professional services; and whether the Company sells the Company’s subscription services without professional services. If the deliverables have stand-alone value, the Company accounts for each deliverable separately and revenues are recognized for the respective deliverables as they are delivered. If one or more of the deliverables do not have stand-alone value, the deliverables that do not have stand-alone value are combined with the final deliverables within the arrangement and treated as a single unit of accounting. Revenues for arrangements treated as a single unit of accounting are recognized over the period of the contract commencing upon delivery of the final deliverable. As of June 30, 2016, the Company did not have stand-alone value for the professional services and training services. This is because the Company includes professional services and training services with the Company’s subscription services and those services are not available from other vendors.
Cost of Revenues	Cost of Revenues Cost of revenues primarily consists of costs related to hosting the Company’s enterprise marketing software platform, providing implementation and ongoing customer support, data communications expenses, salaries and benefits of operations and support personnel, software license fees, costs associated with website development activities, indirect overhead, amortization expense associated with capitalized internally developed software and intangible assets and property and equipment depreciation.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In March 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-09, C ompensation - Stock Compensation: Improvements to Employee Share-Based Payment Accounting In March 2016, the FASB issued ASU 2016-08, Revenue from Contracts with Customers This guidance will be effective for the Company in the first quarter of its fiscal year ending December 31, 2017.
