It has not hit the headlines yet. But a few webmasters are experiencing huge shift in their Google SERPs.
A few comments at Webmasterworld:
My pages lost about 80% of their traffic about 10 days ago or so. Nov 16/17 I noticed a few terms popping back into the top three positions..
My page ranks are shifting back an forth, and the caches are showing old stuff. I'm at a loss of what to do now. If it is a data push, or if it is an algorithm change to push the ecommerce sites ahead of the information sites for the Christmas season, then I wish someone from Google would just let us know.
I lost 90% of my Google traffic in 2 Days (loosing 100/200 places on each keyword :/).
I'm seeing a 350 percent increase in traffic on 1 of our websites.
my website whose is loosing 90% of it's Google traffic is now at the 80th place when I look for: search on google : www.mydomain.com
Not many people are complaining as per now. It could very well be the monthly flux. You can join the Webmasterworld Forum discussions here.
