Other than Adsense, there are also other adverts you can display on your blog. Here are two sites which pays you to display their adverts on your blog or website. Like Adsense, these sites pay you for every click their adverts receive.

You get an instant sign-up bonus of 25$ and the minimum payout is only 50$. They pay you each month by check. The good thing about Widgetbucks ads is that you can display it along with Adsense adverts because their ads are looking entirely different from Adsense adverts.

With Bidvertiser, you get paid each month as long as you reach their minimum payout which is 10$ by paypal or 50$ by check, whichever of the two payment methods you choose. Since Bidvertiser is very similar to Adsense, you should not run them together in one site. Adsense strictly prohibits its ads to be in the same site with other ads which are a resemblance to its own adverts.
