Organization, Consolidation and Presentation of Financial Statements [Abstract]
Description of Business	LinkedIn Corporation and its subsidiaries ("LinkedIn", the "Company”), a Delaware corporation, was incorporated on March 6, 2003. The Company operates an online professional network on the Internet through which the Company’s members are able to create, manage and share their professional identities, build and engage with their professional networks, access shared knowledge and insights, and find business opportunities, enabling them to be more productive and successful. The Company believes it is the most extensive, accurate, and accessible network focused on professionals. The Company also offers diverse products that can be used by customers to transform the way they hire, market, sell, and learn.
Basis of Presentation	Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States (“US GAAP”) and applicable rules and regulations of the Securities and Exchange Commission regarding interim financial reporting. Certain information and note disclosures normally included in the financial statements prepared in accordance with US GAAP have been condensed or omitted pursuant to such rules and regulations. Therefore, these condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2015, filed on February 12, 2016. The condensed consolidated balance sheet as of December 31, 2015, included herein was derived from the audited financial statements as of that date, but does not include all disclosures including notes required by US GAAP on an annual reporting basis. In the opinion of management, the accompanying unaudited condensed consolidated financial statements reflect all normal recurring adjustments necessary to present fairly the financial position, results of operations, comprehensive loss and cash flows for the interim periods, but are not necessarily indicative of the results of operations to be anticipated for the full year 2016 or any future period.
Principles of Consolidation	Principles of Consolidation The condensed consolidated financial statements include the Company, its wholly-owned subsidiaries, and variable interest entities in which LinkedIn is the primary beneficiary in accordance with the consolidation accounting guidance. All intercompany balances and transactions have been eliminated. Redeemable noncontrolling interest ("RNCI") is included in the condensed consolidated balance sheets. RNCI is considered to be temporary equity and is therefore reported outside of permanent equity equal to its redemption value as of the balance sheet date.
Use of Estimates	Use of Estimates The preparation of the Company’s condensed consolidated financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of income and expenses during the reporting period. These estimates are based on information available as of the date of the condensed consolidated financial statements; therefore, actual results could differ from management’s estimates.
Recently Issued Accounting Guidance	Recently Issued Accounting Guidance Credit Losses In June 2016, the FASB issued new authoritative accounting guidance on credit losses on financial instruments which replaces the incurred-loss impairment methodology. The new guidance requires immediate recognition of estimated credit losses expected to occur for most financial assets and certain other instruments. The standard is effective for the Company in the first quarter of 2020; however early adoption is permitted beginning in the first quarter of 2019. The Company is currently evaluating whether this standard will have a material impact on its financial statements. Stock Compensation In March 2016, the FASB issued new authoritative accounting guidance on the accounting for certain aspects of share-based payments to employees, including the accounting for income taxes, forfeitures, and statutory tax withholding requirements, as well as classification in the statement of cash flows. The standard is effective for the Company in the first quarter of 2017 and will be applied using the modified retrospective approach; however, early adoption is permitted. The Company is currently evaluating whether this standard will have a material impact on its financial statements. Leases In February 2016, the FASB issued new authoritative accounting guidance on leasing arrangements. The guidance outlines a comprehensive model for entities to use in accounting for leases, and supersedes most current lease accounting guidance, including industry-specific guidance. The core principle of the new lease accounting model is that lessees are required, among other things, to recognize lease assets and lease liabilities on the balance sheet for those leases classified as operating leases under previous authoritative guidance. The guidance also introduces new disclosure requirements for leasing arrangements. The standard is effective for the Company in the first quarter of 2019; however, early adoption is permitted. This standard is required to be applied using the modified retrospective approach. The Company is currently evaluating the impact of this guidance on its financial statements and expects that most of its operating leases will be recognized in its condensed consolidated balance sheets. Financial Instruments In January 2016, the FASB issued new authoritative accounting guidance on the classification and measurement of financial instruments. The requirement to disclose the methods and significant assumptions used to estimate fair value is removed. In addition, financial assets and financial liabilities are to be presented separately in the notes to the financial statements, grouped by measurement category and form of financial asset. This standard will be effective for the Company in the first quarter of 2018; however, early adoption is permitted. The Company does not expect this standard to have a material impact on its financial statements. Revenue Recognition In May 2014, the FASB issued new authoritative accounting guidance on revenue from contracts with customers. The guidance outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. The core principle of the revenue model is that "an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services." The guidance also requires significantly expanded disclosures about revenue recognition. In July 2015, the FASB voted to approve a one-year deferral of the effective date to December 15, 2017 for interim and annual reporting periods beginning after that date and permitted early adoption of the standard, but not before the original effective date of December 15, 2016. This standard will therefore be effective for the Company in the first quarter of 2018 and will be applied using either the full or modified retrospective adoption methods. In March, April and May 2016, the FASB issued additional implementation guidance related to the new standard. The Company is currently evaluating whether this standard will have a material impact on its financial statements.
