If yu want to earn more money from your blog or website, there is another advertising program like Google Adsense. Bidvertiser is an alternative to Google Adsense but you can use both of them in your blog together. An advantage is that Bidvertiser pays you if you make only $10, and also Bidvertiser gives you $20 to test their service. All you need is to sign up an account. It's free.
