Welcome to WebmasterWorld Guest from 220.127.116.11
The forums deliver 25 million or so page views per month. CTR on forum pages is notoriously low. My CTR should drop considerably while total clicks should go up quite a bit.
Does Google care if you have a low CTR? Has anyone been kicked out of the program for that?
I wouldn't think that it would matter much since the cost of delivering the ads is so small. Just curious.
