It is pretty simple; just do not get banned by Adsense. Follow the rules they have and if you not sure ask in the Google forum and wait to you get an answer from a real person that belongs to the Adsense team. Clicking on your own links and ads are the most common mistake people can do and they think that Google never will find out but they will. Just don’t do it and you can make good money with Adsense for years to come.
