Googler happy to announce that this feature is now available to all publishers. Integrating your account with Analytics will provide you with more detailed information about traffic to your pages and how users interact with your site.
To take advantage of these new reports, sign in to AdSense and click the 'Integrate your AdSense account with Google Analytics' link on your Reports Overview page. You'll be taken to a step-by-step wizard that will guide you through the rest of the process. If you use AdSense in a language that's not supported by Analytics, you can still link your accounts and view your Analytics reports in a different language.
