I'm about to launch a site that allows users to search a database by topic and 3 other parameters. The page is re-entrant ASP and the page reconfigures the title, description and page text based upon the search parameters - there are about 6 million unique page combinations... and could grow to 6 billion. Is this number of pages a problem with Adsense code in the pages? Is there anything else I should be aware of? Does Google frown on this?
Testing the pages shows fairly good ad matching to page content. (I know that the 1st visitor to a page is likely to get PSAs or generic ads).
