Hi I have tried top adsense keywords and it works at first but yesterday, I experience a backlash from adsense. 1.3 cents per click average. Same traffic. I am changing back all my top keywords and using my ordinary keywords. I am happy with 4 cents a click plus I can get more traffic with my ordinary keywords. Traffic rules over keywords.
I used the never thought about it keywords that I got from many sources like "google affiliate", "canda personals yahoo", "yahoo domain name" and many weird phrases. It actually makes sense. Who would have typed these weird phrases in the search engines? Common unfamous words are actually more searchable than mesotheliema.
