Reports via WebmasterWorld that backlinks have been updated over night at Google. What does this mean? I suspect not much, just like it meant very little for the August 25th Back Link update. That update was coined "Pluto" but was pretty much knocked down as insignificant by GoogleGuy.
Great quote from that post;
I agree this one isn't anything to write home about. Like Pluto, I think this would be a shrinking update; the SERPs aren't really changing. :)
