Ad delivery systems want to find good advertising partners easily and efficiently. To this end, available data such as crawled Webpages, access statistics, advertising offers, etc. may be analyzed. The available Webpages may be scored and sorted based on estimated revenue of the Webpages. The scored and sorted Webpges may then be filtered to remove documents considered to be poor prospects and/or documents having characteristics that are considered to make the documents poor prospects, and then presented to the ad delivery system for further use.
