Revenue from Contract with Customer [Text Block]	2. Revenue Recognition The Company generates its revenues principally from subscriptions, either directly with advertisers or with advertising agencies, to its platform for the management of search, social, eCommerce and display advertising. It also generates a portion of its revenues from long-term strategic agreements with certain leading publishers. Revenues are recognized when control of these services is transferred to the Company’s customers in an amount that reflects the consideration the Company expects to be entitled to in exchange for those services. The Company determines revenue recognition through the following steps: ● Identification of the contract, or contracts, with a customer; ● Identification of the performance obligations in the contract; ● Determination of the transaction price; ● Allocation of the transaction price to the performance obligations in the contract; and ● Recognition of revenue when, or as, the Company satisfies its performance obligations. Subscriptions The Company's subscription contracts provide advertisers with access to the Company's advertising management platform. Advertisers do not one not three six The Company's subscription services comprise a single stand-ready performance obligation satisfied over time as the advertiser simultaneously receives and consumes the benefit from the Company's performance. This performance obligation constitutes a series of services that are substantially the same in nature and are provided over time using the same measure of progress. Revenues derived from these arrangements are recognized over time using an output method based upon the passage of time as this provides a faithful depiction of the pattern of transfer of control. Fixed minimum monthly platform fees are recognized ratably over the contract term as the single performance obligation is satisfied. Variable fees are allocated to the distinct month of the series in which they are earned because the terms of the variable payments relate specifically to the outcome from transferring the distinct time increment (month) of service and because such amounts reflect the fees to which the Company expects to be entitled for providing access to the advertising management platform for that period, consistent with the allocation objective of authoritative revenue guidance under Accounting Standards Codification 606 606" Strategic Agreements The Company has entered into long-term strategic agreements with certain leading search publishers. Under these strategic agreements, the Company receives consideration based on a percentage of the search advertising spend that its customers manage on its platform. These strategic agreements are generally billed on a quarterly basis. The majority of the Company's strategic agreement revenue is concentrated in one December 2018, October 1, 2018 ( two three two may no not two one The Company evaluates the total amount of variable revenue share payments expected to be earned from the Google Revenue Share Agreement by using the expected value method, as it believes this method represents the most appropriate estimate for this consideration, based on historical service trends, the individual contract considerations and the Company's best judgment at the time.

Customer Advances The Company records advances from customers for cash payments that are received in advance of its performance of the underlying services. These services are contracted on a weekly basis and cash payments are generally received on a weekly basis at amounts that are at the discretion of the customers, based on established advertising budgets.
