The thing is simple. I want to block everything except "Personalized ads" Why I want to do that? Last day I had CPC of 25$. 2 Click from Canada made me 50$ My niche is IP address check, what is my ip address, ip lookup, whois domain.... When I search for this terms on kwfinder CPC is something lik 3$ MAX. So i suppose that those ads that brings me 25$ CPC are "Personalized ads". I suppose that someone was interested in "car insurance" and google remember their interest. After that this visitors got that ad and I got big CPC. I suppose this because I saw that wife was searching for "travel agencies" in google. Now on her laptop she always get Booking.com website - no matter what she is looking I mean which website she visits. What do you think about this????
