My initial take on this was the same as TOI's... that you might now be getting visitors who are finding what they're searching for more quickly. Or, possibly, that they may be spending more time per page on the pages they visit. This certainly would be in line with what I understand Google is trying to do.
Do you have any measures of engagement onsite? Time on site? Time on page? Any conversion goals that might suggest user satisfaction? Any information about return visitors? How do these fit in with the number of visitors vs page views per visit?
