It cant explain everything ( not that I think you re trying to say it can :) because it falls over when related to single page EMDs with a short content page ( under 200 words ) that have no "exit" available other than a mail link, and still rank in the top 3 on very competitive terms ( 500 million, 1 or 2 billion + results ) and that do not have analytics on..and very few inbounds
No adsense nor other ads..
Didn't get hit by any panda iterations ..nor penguin..
So how would they measure "exit rates" ? ..less than 20% chrome users, so insufficient data from that..and even if they could measure them in those cases ..they would appear shocking and would tend thus to penalise the page instead they leave them alone..
Google has a lot of user metrics..but not , IMO , enough to be using them to rate small sites that have no adsense and whose visitors are not being tracked..
All they could measure is "bounce" ( return to serp ) and unless the visitors are all reading a few hundred words following the sentences on the screen with their fingers and mouthing the words slowly, the "bounce" would be quite rapid..or they click to "mail" or click out to another page, but G are not looking over all their shoulders, they can't track a non chrome user moving page to page who doesn't arrive on successive pages with G's "beacons", be they adsense, double click , youtube , whatever..
In other words automating panda via exit or bounce rates may explain some cases..but not all..G has blind spots, where the automation gets no data to use..
