Hi There ! While chatting with a friend again we came to this idea: Place unrelevant with the rest of the page, high paying keywords on your page. But make them in a very very small lettertype with the same color as your background... This will make adsense display ads with high paying keywords/clicks... right ? Example: On a proxy site, place keywords like mortage and loan and make them size1 with the same color as the background. Adsense should display mortage related ads if you have enough keywords I thought... or am I wrong ? I'm almost sure that this isn't allowed, but I want to be 100% sure so that's why I'm asking Thanks
This was an old way for websites to get high google ranks by placing hidden content and keywords that visitors couldn't read. Not only will it get you banned from adsense but google will take your website off their search engine.
it's against google adsense and it's also against google search because google search will consider it as spam. this may be a reason to be banned from google adsense and google search
Instead of thinking of this things here is something else you could chew on http://forums.digitalpoint.com/showthread.php?t=368136
