goodle adsense best place to put keywords

hey everyone, we all want better paying ads, I know i could put keywords in article, news titles that are indexed by google bots in 1-3 days that would bring better paying ads. but what happens when your site has nothing to do with the keyword you want to use? is there a place to put these keywords where its not visible to the public but visible to the google bots?

This trick has been done for some time now but is not good practice in Googles eyes, hidden keywords can bee added at the top in html boxes, I don't suggest this

Highlight the text above to read

thanks for the help, why don't you suggest them? can get me banned? thanks

Yes, it is written in your Adsense agreement not to use this tactic.

 ok thanks, i cant afford to get banned from adsense.. I will follow ur advise

 Any time you have one thing visible to Googlebot and something else visible to users you're treading on thin ice with Goolge. From text coloring all the way up to full fledged cloaking, I wouldn't recommend any of it.
