If they'll allow me to post examples I will.
First nothing new is being indexed. Products released in early November on many sites are showing up barely in the SERPS. For several niches I monitor all new content is unindexed. There are no cached pages for weeks.
Second the SERPS today hit an all time low. There are specific product searches for top selling products that google instant recognizes....that return few/no products. There are MANY specific product searches that return a homepage instead of the product pages.
Google is garbage today. Whatever they are doing it's getting worse with each tweak.
I haven't looked at my employers site but it must be down. When I search for a well known advertised product and get a three year old blog post you know it's bad
Today is the all time low point. Was it triggered by the nyt article? I don't know but the results are total garbage....webcrawler esque.
