TRUTHFUL PRICING SCHEME FOR SPONSORED SEARCH WITH RESERVE PRICES

摘要

Search engines and sponsored search auctions are provided that enable the use of different reserve prices corresponding to different advertisement slots on a search results page. In one implementation, a search engine includes a query processor and a sponsored search auction. The query processor is configured to receive a query from an electronic device associated with a user, to determine a plurality of reserve prices corresponding to a plurality of advertisement slots of a search results page, and to determine a plurality of bid prices for the advertisement slots of the search results page corresponding to a plurality of bidders. The sponsored search auction is configured to allocate a bidder or a null (e.g., no advertisement) to each advertisement slot of the search results page, taking into account click through rate information regarding the plurality of bidders.
