Abstract: A method and system for generating a price landscape for an advertiser for bids placed by the advertiser for advertisement space is provided. A price landscape system generates a price landscape based on information provided by an advertisement placement service that may include overall price estimation data and advertiser-specific performance data. The price landscape system generates price landscape data for an advertiser that combines the overall price estimation data and the advertiser-specific performance data to provide a more accurate assessment of the advertiser's expected performance than can be determined from the overall price estimation data or the advertiser-specific performance data alone.

Abstract: An ad system allows a user to create and manage an ad campaign that is administered by two or more ad engines. The ad system interacts with the ad engines using a channel abstraction interface module. For each ad engine, the channel abstraction interface module translates ad information from an engine-agnostic format that is associated with the ad system to an engine-specific format that is associated with the ad engine.
