We discussed earlier how rewarding the Google AdSense program can be. However, joining the Google AdSense program is not that easy or everyone in The world would do it (which would defeat its purpose, ultimately). You have to be approved by Google in order to create your AdSense account and start earning money from it.
How do you get approved? Google famously has never publicly published details of its approval process, but there are tips you should follow to ensure a high possibility of getting approved.
The good news is that Google does publish its policies and you do not need to be a member to read them. You should read them and be certain that you are in 100% compliance with them, not only when attempting to start your AdSense account, but once you are already a member. They update these policies regularly and a violation will get you suspended. A list of Google AdSense Policies can be seen at: http://www.google.com/adsense/policies
