Sites that contain ads for beer, liquor or tobacco products are not allowed to participate in the Google Adsense program.
Sites that promote hate or racist attitudes are not allowed to participate in the Google Adsense program.
If the site you are considering promotes gambling, drugs, even prescription drugs then it is not suitable for the Google Adsense program.
A good guideline to go by might be if a site is family oriented. That may not cover everything but it's a starting place. Again, check the Program Policies for more information.
Why Your Should Not Pay for Your Own Blog Site
If you already have a website that showcases your wares or you've been thinking about getting one, that's great. Since you're working on building a business anyway, you can only profit more by implementing Google Adsense on your site. As long as it conforms to Google Adsense Program Policies of course.
If, however, blogging is your interest, I say stick with the most popular blogging site you know. Or even two or three of them. Why? Traffic. Lots of it. Blogging on an already populated site versus dreaming up your own blog site is like the difference between 5:00 traffic in New York City and an old dusty country road.
