If you have a single ad unit w/great placement and you're getting relevant ads, it's possible on a single page to get 20%.
whats wrong with u. why u r giving this kind of post "Fuck adsense mom " and in another thread u said "Adsense owner had sex with his mom" If dp member will report u then u can ban. mate if u r not doing anything wrong then how its possible but always check ur a/c
If you are not doing anything against the TOS, you are ok. I've CTR above 20% all the time, especially in the morning.
If you aren't doing anything against TOS you are perfectly safe. I've had 20%+ CTR days before and I still have my account after more years.
i have around 1% . there's nothing in the adsense TOS about banning an user for high CTR .don't worry.
You should be fine, but the T&C... It takes time and evaluation to stick to them. I was banned years ago as I shared computer with family. They used to visit my websites and click on Adsense. They don't listen to excuses.
