please take a look at my site to see if i am in breach of adsense rules. Look at the keywords at the top of the page. If you click on one them it is the same as searching for those keywords. Money can then be made when they click on the ads of the search page. Is this allowed?? i have not seen it before on any other sites link
I'd say doing this with AdSense For Search would be a risk. This doesn't mean that it's against TOS (I'm not sure if it is), but IMO this is borderline deception. People are searching for "videos" by those keywords and instead end up on search results. Not even worth it when you can get similar results with Google Co-op. http://www.fka200.com/2007/12/27/step-by-step-tutorial-to-make-money-with-google-coop
