I don't know what happened by by CTR today is now 7x more... is this a bad thing? I'm not sure? All I did differently was add a border to me ads (which I thought would lower my CTR?). Should I notify adsense about this spike? *note CTR from X% to XX%
7 times more does sond excessive. If had no click and got 7 today then you are probably OK. If you had 10 clicks and are now getting 80 then it could be a cause fo concern. Of course, this assumes your traffic level is still similar.
My case is one day the earnings went up to 7 USD from 2 USD of the previous day. I decided to notify Google to make sure that I would not get banned if there was a sabotage or invalid click activity. They said they will keep a very close eye on my blog and the payment would be delayed. --"
My CTR has gone extremely high at one point but it wasnt anything todo wid fruad or nutin :S dont worry if you aint done nutin wrong den its all good
