have you ever heard of someone with a 50%+ CTR? and if so wouldnt goolge think fraud is involved and cancel the account?
umm no, never heard of that before. I dunno i doubt they can accuse you of fraud just because your more than good with ad placement, although i've never heard of 50%+ CTR
Depends over how many clicks, if you're getting a 50% CTR with over 1000 clicks then it'll probably flag something. If you're getting 50% CTR with only 5 clicks or so it could just be luck!
