This whole analysis is bad and sensationalistic.
His observation is based on 1 search term. In order to make right conclusion someone should analyze at least tens of thousands (or even hundred of thousands) search terms.
He also analyzed 1st page results only. He didnt even try to see what sets apart 1st page results from 2nd/3rd/4th.
He points to single factor, totally disregarding other factors and their relative importance as part of whole algorithm.
