Here is what I see: The third day of traffic being substantially lower across all websites for me, somethings changed, not too sure what as yet.But there was an update from September 2-4 so after the weekend we will know more.Biggest drop ever, much bigger than panda. Thats my courteous terminology:-)Here is what the tracking tools are showing.Mozcast: Semrush: SERPmetrics: Accuranker: Cognitive SEO: Advanced Web Rankings: Algoroo: RankRanger: I understand it is Labor Day today and the chatter will be slow. I likewise question Google pushed something significant over the Labor Day weekend.
