I usually get 12% - 44% as referrals CTR but Today i saw a 100% CTR .... I am really anoyed .... please advice me about the next step ...........
how many clicks are you getting? if it's not too much, it will not be a problem. for example, 10 impression and 5 clicks is no a problem
clicks on referrals is not a problem.. "click fraud" can only happen on PPC, where the advertiser pays for every click. Since referrals are PPA, nobody really cares how many clicks they get.. IF however, you get 100%CTR and then 100% conversions, then you might have something to worry about.
