At my website www.followtwitter.net, users can write their own descriptions. However, this seems to affect what ads are shown. Is there anyway to make AdSense ignore this content and focus on my proper keywords? Thanks.
It will work because content in an iframe is not part of the content of the main page, it is just a window within the main page that shows content from another page. As its not part of the main page, Adsense wont see the text in it, and so wont show ads based on its content... This may help you: http://www.w3schools.com/TAGS/tag_iframe.asp
