BROAD MATCH CONTROL

摘要

Methods, systems, and apparatus, including computer programs encoded on a computer- readable storage medium, for evaluating a creative. A method includes: identifying one or more selection keywords that are associated with a creative, the selection keywords used in determining when the creative is shown in response to received content requests that include one or more request keywords; identifying matching criteria for comparing the selection keywords and the request keywords, the matching criteria defined by a range from an exact match to a broad match and including a matching threshold in the range; establishing a bid modifier associated with the matching criteria, the bid modifier modifying a bid associated with the creative based on an extent of a match determined between the selection keywords and the request keywords for a given content request; and evaluating the creative responsive to received content requests based on the matching criteria and the bid modifier.
