Google filed two patents this week dealing with ad targeting based on user search history behavior and personalization in what seems an attempt to enter the post-search behavioral advertising market that Yahoo is already offering to its advertisers and will be available in MSN’s AdCenter. The patents also follow a line of filings, including the Google filing of a creative and landing page optimization patent filing in September.

The first Google patent filing discussed is "Determining ad targeting information and/or ad creative information using past search queries" which was authored mainly by Sumit Agarwal. The patent abstract describes this patent as follows : Ad information, such as ad targeting keywords and/or ad creative content for example, may be determined using aggregated selected document-to-query information associations. For example, popular terms and/or phrases also associated with a selected document may be used as ad targeting keywords and/or ad creative content for an ad having the document as a landing page. Query information may be tracked on a per document level, a per domain level, etc. The determined ad information may be used to automatically populate an ad record, or may be provided to an advertiser as suggested or recommended ad information.
