Kontera
Kontera can be a great way to increase the money you can make from your site and blog. Kontera is a little different with AdSense. Their ContentLink In-Text Advertising system will underline the relevant keywords of the content in your web pages. When a visitor points the mouse to a underlined keyword, an ad will show up. If the visitor click on the underlined keyword, you'll earn money. Below is a screenshot of Kontera content link

Kontera works with publishers from most of the countries in the world. But they also have a set of policies to meet to become their publishers.
