Google is soliciting feedback on how Google Analytics can help webmasters be successful in AdSense. The feedback is running on Google Groups, so you’ll need a Google account (if you are using Google Analytics, you already have one), and your comment will be public.
Back in SES San Jose, I asked some of the Google people on the possibility of tracking AdSesne clicks within Google Analytics. At that time, I did not get anything definitive. I am glad to see that Google is offering this ability now. Personally, I’d like to see how clicks on Adsense ads correlate to the entry source (referring domain, keywords, etc). That type of information would be very helpful in telling webmasters which channels they should focus on optimizing.
