So what does the Google Shuffle history look like for this holiday season? (it's not a Google Dance anymore - so I'm calling it the Google Shuffle.)
Here's what I can gather - feel free to add, subtract or whatever:
Oct 22 - pretty big algo change, supposed to be a refinement of Mayday long-tail changes reference [blog.alexa.com]
Oct 31 - a smaller adjustment, some sites hurt on Oct 22 report recovery
November, to me looks like a string of small tweaks and algo adjustments. Nothing sweeping across a large swath of sites. In other words, whatever you saw going into November is pretty much hanging around.
