Determining content to be provided by an entity for rendering via a resource in a target document or notifying an alternative entity of the availability of the resource

摘要

A method and system for allowing a resource associated with a target document usable for ad rendering by a first entity to be used for rendering of content by a second entity. Depending on one or more conditions, the first entity either uses the resource to render at least one ad or allows a second entity to use at least a portion of the resource to render content.
