so i can use same adsense code for my various websites, but what will happen if one of my site get banned by google adsense, will adsense ban for my all site or for just that single site, i am not going to do anything bad, but if by mistake something happen will they ban my id or only that particular site ? i am really afraid.. fingers crossed.
Are you sure that you have not violated any of the terms of Google Adsense? You can use only 3 ads unit per page. If you used 1 ad unit in two your sites... this is the reason.
If you have violated any rule and one site gets banned, All the sites where you are using the code will get banned from google to save his advertisers. He will send a genetic reply such as "Invalid click activity" .... So make sure you are not violating any policy.. The content of the website is fine, You are using 3 ads unit per page maximum and not clicking your own ads... Please explain what exact you are looking for, I will be more then happy further assisting you on the same.
