Admob 8% CTR. Something is not right.

Did anyone else experience a huge jump in CTR in the last few days using Admob?

For some reason, in the past 7 days, the CTR on my interstitials has been in the 8% range and I’m a bit scared that it will raise some red flags.

Is this just a fluke, or is there something else in play… bots?

Last 2 days CTR was highest till now. may be some attractive ads.
otherwise there is no layout change from myside.

yeah, yesterday was insane and the day before was decent too.
I was in the process of switching to other networks, but now I guess I’ll wait another week and see.
