I recently started an ad sense account and i am having a hard time getting more then one ad to show up. Google says they are crawling my site for content, but the sites content changes daily so what am i doing wrong?
Check your robots.txt and make sure it's not blocking google particularly the mediapartners-google bot. Check your access logs things like: 66.249.71.198 - - [25/Aug/2009:23:13:06 -0500] "GET /Success.html HTTP/1.1" 200 11090 "-" "Mediapartners-Google" Indicate that the adsense bot is scanning your site for content. If you don't see that then something might be wrong with your robots.txt file.
Try Google adsense section targetting which will tell Google the keywords to choose for displaying the ads. It does not matter if your sites content changes or not. Google ads will automatically show and change depending on the keywords in your site.
