Some one click on two time on the ads (or two ads) on the enterance page. Nothing to worry if this only happen once. If this happen continuously for few days, shall report to adsense team
It this happens often, then you should report it to adsense support because someone might be click bombarding to your website and you may get banned without your fault.
On 2 clicks who cares? Probably just an anomaly. Now, if that were 2,000 clicks and you had that high a CTR that'd be something to show here!
I've had this happen to me before aswell, when I went back a few days later and checked again it was back to normal, I think it's just an occasional glitch. If you subsequently find your account is banned open up an enquiry straightaway
If you have a Leaderboard unit (text only), then it's possible for you to get 4 clicks from one impression. There really is nothing to worry about for such a low number of impressions
It happens from time to time, just wait until stats update again in one hour or so, all will be back to normal.
It also happens quite common at the beginning of the reporting day. If the first visitor clicks an ad at 12:01 your time.....you'll have a 100% ctr. If that person clicks two ads you'd naturally have a 200% ctr. CTR will drop throughout the day..
YEs your account will be safe as long as you follow adsense TOC. You can report the issue to G.Adsense team if this ctr persists. Most of the times ctr will hower around 2-3 %.
