Here's an interesting article from former Google research scientist, Asutash Gorg. He left Google in 2008 after more than four years on staff. I always appreciate a look at what Google is (or was) working on behind the scenes. In this case, it sounds like Asutash might know at least something about Panda.
A Mathematical Model for Assessing Page Quality
Behavioral score of page – How people perceive a page is a big indicator of the quality of the page. This can be measured by analyzing the user behavior. Some of the factors that are traditionally used are –
1. Conversion score
2. Bounce rate
3. Number of page views
4. Number of repeat visitors to this page
5. How many people add products to cart after visiting this page?
6. Average amount of time that is spend on this page.
Still no clue as to where Google would get this data - especially since we now have a public statement that Google rankings do not use any data from the Chrome browser [webmasterworld.com].
