ADVERTISING SYSTEMS AND METHODS

摘要

Advertising systems and methods are described that are configured to receive bid requests for ad placement. The bid requests include a bid amount and an ad type, category, and/or geographic area. The ad type includes click ads, call ads, and/or call and click ads. Ad pricing is determined for ad placement using the bid requests in a dynamic price auction. The ad pricing includes a floor price and/or another ad price. The advertising systems and methods are configured to periodically modify the ad pricing according to price correlation data among ads having different ad types. Ad pricing also includes optional fixed-price advertising for set time periods for a subset of advertisers based on auction bid prices. One or more ads are placed in electronic ad spots according to the ad pricing. Search results that include the placed ads are presented in response to a user search queries.
