I have just logged into my AdSense account and I am so pleased to find what appears to be new features including detailed statistics. There is now the ability to create channels - in other words, groups of pages, which can be used to monitor different sections of your site. Not only that, but AdSense can now be placed on framed pages, and more! Definitely worth checking out!
Great job Google! We can now track what parts of our site is performing the best :)
