I am crazy now. I have 3 websites and I put google adsense on them - it is one account since they said it can be done like this because they are all my sites. At the beginning of this month, I found the impression is normal - mroe or less then 100,000, but the CTR is over 20% while normally it is 1% -3%. I was thinking that someone use the bot or some program to clicks - as you know, the Google code can get from website resource. I reported this to Google Adsense Team with no response. Today I received an e-mail from them saying my account is disabled because of invalid clicks. I am really angry with this and why Google doesn't want to improve the code so that noboday except me can get it? Please adivce.
