Advertisement marketplace

摘要

A marketplace (or aftermarket) for advertisements or ad combinations is established. A first on-line advertisement is identified in which a performance of the first advertisement during a past ad campaign is above a threshold. A second on-line advertisement is identified based on a matching criterion between the first and second advertisements, in which a performance of the second advertisement during a past ad campaign is lower than the first advertisement. The first advertisement or a representation of the first advertisement and performance data of the first advertisement are provided to a sponsor of the second advertisement.
