I had a Google Adsense account since last 3 years working very well. Suddenly I got a mail stating the following message. What would be the reason?? I didnt had any any activities that bears disabling the account
That's the email they send out if you have violated the Program Policies in some way. Some frequent reasons - non-allowed content - tricky ad layouts - no Privacy Policy What URL(s) were the ads on?
I didnt encounter any of the reasons you mentioned. the URL is http://webdesignfolio.blogspot.com/ on the right side ads were installed.
There's no privacy policy on there now for sure. But that isn't the major issue if the reason was invalid clicks.
this happened to me and i contacted them from the adsense help center and then found the account re-enabled. you can contact them and inform them that this is an error.
