SUGGESTING AND/OR PROVIDING TARGETING INFORMATION FOR ADVERTISEMENTS

The relevancy of ads may be increased, and opportunities to serve an ad that might otherwise be missed may be exploited by (i) accepting broad targeting information, to be used for serving an ad, from an advertiser, (ii) serving the ad using the broad targeting information, (iii) logging search query terms (or some other information, such as concepts, concept keywords, etc.) associated with the serving of the ad, and (iv) generating one or more candidate targeting keywords or phrases for the ad using the logged search query terms. At least one of the candidate targeting keywords or phrases may be provided as targeting information for the ad. Alternatively, at least one of the candidate targeting keywords or phrases may be presented to the advertiser. Advertiser input with respect to the candidate targeting keyword(s) or phrase(s) presented may then be accepted. Zero or more of the candidate targeting keyword(s) or phrase(s) may be provided as targeting information for the ad, in accordance with the accepted advertiser input. Cost information (e.g., average cost per selection, average cost per conversion, total costs, etc.) may be presented in association with the candidate targeting information.
