My account had less than 1% CTR and have been in use for more than a year. I hardly saw the stats as i got 1 or 2 clicks a month or so. Yesterday, I got the same usual reply that my account is risk to advertisers and blah blah blah... So, contrary to what most thought that CTR below 4 to 5% is ok...this is not the case..even if you don't generate any clicks also, it seems, you are at risk to advertisers....The company account that i work for generates 8 to 9% CTR and i been telling them to wait till they get banned and i got banned instead Just a heads up to you guys CTR% is not a stat to go for to check if the account gets banned. Thanks
They don't just look at the CTR they look at a whole bunch of factors including the CTR, the amount of invalid clicks, the type of traffic you send, the type of website it is and many others
ctr is not an only thing but they consider from your sites, your contents, visitors and many more things. show us your sites and we may can tell you why google banned you.
Check which of the adsense TOS is violated. CTR alone, that too at less than 1% may not be a reason for being banned. You can go in for appeal after rectifying your mistake.
Even the strongest will getting old,sick or died one day, you can get paid from adsense for many years, but you'll lose everything if you get banned just 1 time. That's why many people purchased insurance for them self, and i getting adsense back up account for myself.
I think CTR is not the actual reason to banned your account. The traffic source and other some issue will be responsible for it.
Can be the cause of invalid clicks. To be banned, one doesn't need 100 invalid clicks or time of payment.
