The following are essential points you need to know before you start your AdSense campaign. Any vitiation may cause your account to be banned.
1. Never click ads on your site by yourself. Self-clicking is considered fraudulent and results in immediate termination of your Google AdSense account. In that case, Google will no longer pay you. Also, you will not be re-approved in future.
2. Do not join mutual clicking network. Since the dawn of Internet, there are websites that attract a lot of webmasters who click advertisement on each other’s site in order to increase click-through rate as a way of making money. This is a highly unethical behavior.
3. Do not ask your friends or relatives to click ads on your site.
4. Do not violate any other policies published by Google. Detailed program policy can be found at:
