If you’re looking for ways to further monetize your blog, take a look at Kontera. It’s a unique contextual advertising system that scans your website for keywords that match their ad inventory. The keywords on your page will appear as active links but these links look slightly different from regular links (they have a dotted line below the regular underline). When the mouse cursor is hovering over the Kontera links, the ad will show up on the page. It’s sorta like the Yahoo! Search box that pops up on the page when you view Yahoo News.
