Google.com Search Results Update? Google Ranking Update?
Google is constantly updating the search results pages. But there seems to be a lot of discussion about an update made to the Google search results yesterday.
A DigitalPoint Forums thread and more conversation at a WebmasterWorld thread report such changes. Here are some quotes from some Webmasters:
Once again there has been an update and as usual I lost another 30% of my traffic from Google. Soon it'll be down to nothing and that is without me doing anything except adding more pages, fixing some typo's and a few layout fixes.
Yes, there definitely has been an update or algo movement yesterday. My first guess is that there has been some movement on dup content filtering measures.
Personally, I have yet to see any changes myself. But I admit, I do not look as carefully as most these people.

I see some adjustments in a random sampling of search results but it could be that if Google stripped pages of the ability to confer internal PageRank and link anchor text when they adjusted Toolbar PageRank that all we're seeing is the inevitable consequences of such penalties.
The loss of internal PageRank from links on sites Google penalized could have knocked some pages out of the Main Web Index into the Supplemental Results Index.
And the loss of link anchor text from penalized sites would obviously hurt the inflated relevance scores a lot of "optimized" sites depend upon.
