After years of secrecy on how much cut Google takes from publisher revenue earned through Google Adsense the company has finally let the cat out by officially announcing the revenue share figures, in a bid for greater transparency with AdSense publishers - Google revealed that it pays 68% of the revenue that it collects from advertisers to AdSense for content publishers and 51% to AdSense for search partners.

Lately Google is experimenting new ad-formats and ad-styles to attract more clickers to its Google Adsense advertisements, while testing my website in Apple Safari 4 Beta it displayed a new experimental ad-format named "Interesting Items by Google", the advertisement module displayed an RSS logo with links to an completely untargeted recipe website as shown below.

The new ad-format seems to pull related RSS feeds and display them in the module, but in my case it was way off-target displaying recipe ads, this is still experimental and the targeting should get fixed once this is rolled out to all users and publishers.
