Ok so I have proxy website, I don't get high paying ads on it. Would it be possible to maybe put some content in there based around high paying keywords, to trick adsense-bot into giving highter paying ads?
Content will help with getting better targeted ads. You still need to make sure your content is in keeping with your site or you are looking for trouble. Here is a code that adsense allow you to use if there is certain content you want them to target. <!-- google_ad_section_start --> Put this code before the content you want targeted and at the end of the content as shown. <!-- google_ad_section_end -->
