There is definitely an update in progress as of 9:20pm EST on 4/10/2012.
Monitor multiple rankings for various keywords in our e-commerce industry that is very specific.
I'm seeing a lot of crap in the results. Not to give any specifics, but a lot of the goods our industry sells is sold via its country of origin, so keyword would be like "polish widget"
Tonight using all various ways of accessing Google (logged in, logged out, goosh.org, etc.) I'm seeing lots of stuff like 4/10 results being translation websites to translate the term "polish widget" from english to polish, etc.
Same can be seen on other keywords, where it looks like a ton of web spam creeping way up to the top. None of it is "local" type results, it is all blog spam and adwords type sites that I've never seen before.
As much as it pains me to say this, results from Bing and Yahoo contain no spam and results are very relevant.
Anyone seeing anything similar?
