As I've stated in other threads I don't typically get concerned about day-to-day fluctuations in rankings but I have to say -- I'm seeing the earth moving in this one.
Sites in my 300+ company strong local competitive field, most of whom know how to rank, are all over the place in the last few days.
I can see some notable specifics about what is being affected the most because I have been studying this niche, with these same 30 pages of sites, for about 2 years.
There is a very comprehensive bubble sort happening. But the blackhat sites that I would be hoping to see fall from results are actually gaining in rank. I hope it's simply a matter of needing the cream to rise to the surface so it can be skimmed off.
