Yet another Google Plus One question: Does it affect ranking for people that you are NOT connected to?

[seanmccauley]

Title pretty much explains it all. If lots of people plus one (the new verb of 2011?) a site, is that site deemed 'popular' and therefore will appear higher up the SERPS generally? Or does it only affect those with whom you are linked via Twitter/Facebook/Google+?

Or is it too early to tell yet?

Too early to tell.  Google is rolling out to many massive changes for any reliable unit testing, IMHO.

Darn.  I'd love to know as well.  I've been scouring the web and it seems like the consensus answer for social indicators as a search ranking factor is:

Facebook Shares:  No causation but high correlation.

Twitter:  Probable causation (anecdotal evidence only)

Google +1: Very little information.  Though it seems likely that Google would use its own social indicator in general search.  I hope SEOmoz does a study on this soon.

Would love to know the answer to this.  My feeling is that the +1's do make a difference regardless of linkage of profiles.
