Abstract: A first request on a second domain associated with the computing device is received, by the computing device, from a user device, in response to the user device processing a webpage associated with a first domain. Handler instructions are sent, by the computing device, to the user device. A second request including a target URL is received, by the computing device, from the user device. Setting instructions to set a first cookie on the second domain associated with the computing device and redirection instructions to redirect the user device to the target URL are sent, by the computing device, to the user device.

Abstract: A method is performed by a computing device. A request including request data, the request data including one or more identifiers, is sent, by the computing device, to an ad decision server. Payload data, including advertising creative retrieval data for downloading one or more generated advertising creatives generated based at least in part on the request data is received asynchronously with respect to the request, by the computing device, from the ad decision server. One or more advertising creatives of the one or more generated advertising creatives is downloaded, by the computing device, based on the advertising creative retrieval data. An advertising creative display opportunity is generated by the computing device. A first advertising creative of the one or more advertising creatives is selected, by the computing device, based on advertising selection criteria. The first advertising creative is displayed, by the computing device, in the advertising creative display opportunity.

Abstract: Interaction-based pricing of electronic ads is disclosed. An indication is received of a first interaction by an individual with an advertiser at least in part via an electronic advertisement that has been displayed to the individual. The electronic advertisement provides two or more distinct interactions the individual could elect to have at least in part via the advertisement and each of the two or more distinct interactions has associated with it a corresponding interaction-specific value to the advertiser. The advertiser is charged, in response to the indication, an interaction-specific amount associated with the first interaction.

Abstract: A data processing apparatus for propagative correlation can include a memory to store a raw matrix with object identifiers and actor identifiers, in the presence or absence of a quantified matrix element, and a background module to convert the raw matrix into reclassified matrix blocks as a function of a criterion linked to the quantified matrix element. The data processing matrix can also include a selection manager to search for an input actor identifier in a first table, the links of which associate an actor identifier and one or more matrix blocks, and to present information depending on the contents of the associated matrix block or blocks. The background module can also include a cross-classifier to convert the raw matrix of the matrix element and a value matrix of the matrix element. The selection manager operates on the basis of the reclassified matrix blocks.
