I just released my new MediaWiki extension called Google AdSense.
Google AdSense is the program that can give you advertising revenue from each page on your website—with a minimal investment in time and no additional resources.
This extension will allow you to add all types of Google AdSense as you need. It can display AdSense for content with specific channel, AdSense for search, and Referrals. Also you can put AdSense anywhere in your content page.
Detail information can be found at paulgu.com , under Projects. You are very welcome to download.
