Something awry is going on. We have product pages, with sub pages on separate URL's with little content. Google is randomly throwing up those sub pages ahead of the main page which has lot's of unique content on popular products.
Not sure if it's connected, but something appears not to be settled properly in recent Panda updates, as these URL's are less relevant.
