Ad Selection Systems and Methods

摘要

Systems and methods are described for dynamically selecting an advertisement for presentation to an end user in combination with an electronic content item. In one embodiment, a control associated with the electronic content item is evaluated to determine whether the advertisement is permitted to be presented in combination with the electronic content item. A control associated with the advertisement is also evaluated to determine an amount that the provider of the advertisement is willing to pay to have the advertisement presented to the end user in combination with the electronic content item. If this amount is greater than the amount bid by other advertisements, then the advertisement and the content item are presented together to the end user.
