This is I think the most important point of all. If you do not meet this point nothing will serve us the other tips. First of all I advise you to carefully read the AdSense Program Policies. Now we will analyze the most common violations. All of us have crossed his mind ever click your own ads, or ask our visitors to click on ads to ayudandos. Well no, we are helping. On the contrary, this can hurt us much. Google is like a god who does not miss one, and if he gets angry may be the devil himself. (Google is a joke, for God's sake do not be angry). If Google has any suspicion that we're cheating, do not think it's going to look for evidence (the famous phrase, we are all innocent until proven otherwise it'll) to punish, ninth. In the first suspect google disables us for life without giving explanation, leaving us to explain, nothing! And even might sue us proves to be suspect. So I advise WARN, not self clicker, do not ask your guests to do so, do not use tools or software to do that for you. Be smart, are not going to get rich from one day to the other. But if cheating can become poor in one day to the other. I repeat, read the program policies, does not go only by the subject matter recently, we also have to be careful about the content of our site, the source of our traffic, etc..
