Google AdSense ads have become ubiquitous. It\’s hard to find many sites that aren\’t running their contextual text advertisements.
However, there ARE other options available for site publishers wishing to monetize their web pages. I recently came across a site called Kontera. They have a different approach to contextual advertising. Rather than display ads directly on the site, their engine looks at a web page and highlights certain keywords on the page by placing a double blue line underneath the word.
You might even see an example of this on this web page. Simply run your mouse over the link, and voila, advertisement that may provide additional useful information for my readers. Try it!
If you own a site, you may want to take a look at putting Kontera on your pages.
