Social’s Direct Influence on Search
So far, we have pointed out the indirect influence social enablement has on search results. There is some hope that we will be able to measure this more directly in the future. For now, it is fuzzy math.
But it gets better. For the first time, the experts claim that social features have direct impact on where a page ranks in Google. According to a study by SEOMoz, for the first time the data suggests that pages with page-level social metrics enabled tended to rank higher. Indeed, the correlation appears to be nearly half as strong as page-level keyword factors and a third as strong as page-level link factors.
