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.
