I made test with Yoovi's Top50 websites (http://www.yoovi.com/top50.php). Some of them are heavy advertisers on french CPC market but Keycompete find only 2 or 3 keywords.

Seems to work better with anglophone keywords/web sites.


Note : The concept is very promising. Maybe my company will build such a tool for french market. But we already have projects for forthcoming month...
