How much of an impact will this really have though? My understanding is that if the searcher is not logged into a Google account, nothing will change.
The amount of people searching on Google, who are actually logged into a Google account, has got to be incredibly small. The only reason most people have a Google account is for gmail, and what % of the overall email market is Gmail? (compared to the others?)
Am I missing something here? (usually am so go easy on me)
