Altough the keywords are on the page, i still dont get useful ads most of the time... Is it adviced to mail google and ask help ? Also, what mailaddress would be most appropiate for that?
Might be worth checking Google's "Site Diagnostics" service in adsense. http://adsense.blogspot.com/2006/07/run-dont-crawl-to-new-site-diagnostics.html
