I think you are asking to be explained that how to made money, just creat a free blog and own a domain, attach it to blog and you can get thousands of free attractive templates.. but pick a topic and then select a template related to your topic (theme), write your own content, post in forums and get backlinks in directories and blogs. and soon you will be earning good through PPC Programs like Adsense, Chitika, adbrite etc all the best
Make a site and add useful and informative content in it. Then add ads in your site and try to do some SEO. The more targeted traffic you can get, the more money you will make.
The question is a little bit murky at best to me. But if you really want to know how to make money on adsense, then you simply have to create a free blog or a website and put good quality contents and update them everyday. Then you can put your adsense codes in the pages and make sure to follow Google adsense TOS
