AdSense
After creating some posts, insert AdSense to your blog to monetize it.
First, you have to register with AdSense. Actually, I don't have to talk much about this as you can refer to one of my blog, AdSense Help. It covers almost everything, from how to set up AdSense until how to maximize your earnings with AdSense.
Just click this link, http://adsense-help.blogspot.com. This link will appear in new window, so you don't have to worry about losing this site.
If you are not interested with AdSense, or your application has been rejected, you can try Oxado. It works just like AdSense. You can read the review here, http://i-want-to-be-a-millionaire.blogspot.com
