Abstract: Systems, methods, and computer-readable storage media are provided for altering clearing price logic at auction time. Configurable parameters included in the clearing price logic make the logic configurable at run time based upon one or more of an ad size, the identity of the pages on which ads are presented, the content of the pages on which ads are presented, a targeting segment of which a user or browser ID is a member, or any combination thereof. This enables experimentation in the exchange and optimization of the logic without requiring alterations in the code and ensures that the price paid is at least equivalent to the minimum bid that would have been needed to win the auction.

Abstract: Systems, methods, and computer-readable storage media are provided for determining configurable auction parameters based upon historic auction information that includes identities of auction participants or bidders. Such configurable auction parameters specify values to be applied for particular auction parameters (e.g., floor price), at the time of an auction for available advertising space, when one or more of the auction participants are associated with specified identities. Further provided are systems and methods for, at the time of an auction for available advertising space, determining auction parameter values in accordance with configurable auction parameters.
