Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer program product, for selecting advertisements. In one aspect, a method includes receiving publisher selections of advertisements; associating the selected advertisements with an advertisement environment in a document; generating an advertisement request code for inclusion in the document; evaluating performance metrics for the selected advertisements; and in response to determining that the selected advertisements do not meet the performance threshold, optimizing the selection of selected advertisements based on the performance metrics; substituting a selected advertisement with a candidate advertisement and causing a client device to render the candidate advertisement in the advertisement environment in the document.

Abstract: Advertisements are selected from a plurality of advertisements and associated with an advertisement environment in a document. Document advertisement request code that is configured to issue an advertisement request for one of the selected advertisements for presentation in the advertisement environment is stored in the document.

Abstract: A system sends ad content to a publisher, where the ad content includes a first snippet of code. The system receives requests from browsers accessing a document at the publisher that includes the ad content, where the browsers send the requests based on execution of the first snippet of code. The system transmits, based on receipt of the requests, a second snippet of code to the browsers that instructs the browsers on a content, format and appearance of text to be inserted within the document when the browsers render the document. The system tracks each transmission of the second snippet of code to determine a number of times the text has been displayed at the browsers.

Abstract: Methods, systems, and apparatus, including computer program products, in which an selections can be received, the selections including a content item (or items) and a creative item (or items) from a user. The advertisement creation engine can use the content item(s) and the creative item(s) to generate an advertisement. The advertisement can be distributed to a community (e.g., other users).

Abstract: Methods, systems and computer program products for estimating a CPC bid (eCPC) as a function of a target CPA bid based on predictive data (e.g., predicted conversion rate) have been described. The eCPC parameter can be used to develop a model that could be used to charge advertisers on a CPA basis while crediting publishers on a CPC basis.
