My main site is kinda moving around a bit today, mostly downwards.
But I do not see anything too weird here: MozCast - The Google Algorithm Weather Report
One thing I did was create a Google Plus page that points at my site. I wonder if this is G's way of identifying businesses and maybe I took a bit of a dive becuase of that? Since google doesn't' want to rank businesses?
(OK that is a bit of a longshot but I am in a pessimistic mood with G today)
