Easy AdSense Lite (released under GPL at http://wordpress.org/extend/plugins/easy-adsense-lite/) is an updated version of a very popular (downloaded over 600,000 times) WordPress plugin. This Lite edition of a premium plugin manages all aspects of Google AdSense for your blog. Easy and complete! It can insert ads into posts and sidebar, and add a Google Search box. With its full set of features, Easy AdSense is perhaps the first plugin to give you a complete solution for everything AdSense-related.
Easy AdSense comes in two versions: Lite and Pro. The Lite version of Easy AdSense is fully functional. But the Pro version gives you more features and control. In the Pro version, you get a filter to minimize the chance of your AdSense account getting banned. It uses a fast and effective keyword matching algorithm to examine the contents (including comments that you may have no control over) of each page on the fly and determines whether the page content could look offensive to Google. If so, it prevents your ads from appearing on those pages. And you can tweak the strength of the algorithm. The Pro version also lets you specify a list of computers where your ads will not be shown, in order to prevent accidental clicks on your own ads -- one of the main reasons AdSense bans you. It also sports a few more updated features compared to the Lite version.
The Pro version is on sale at http://buy.ads-ez.com/easy-adsense for $4.95. The Lite version can be downloaded from the WordPress plugin repository or http://buy.ads-ez.com/easy-adsese/easy-adsense.zip
