Over the past 24-48 hours there has been an uptick in chatter across social media, the SEO communities and the forum threads around Google ranking and search results shifts. In fact, it has been pretty volatile over the past couple of months based on our reporting. But there seems to have been something going on, maybe a test, maybe the beginnings of a roll out in the past day or so.
The ongoing WebmasterWorld thread has chatter of course, here is some of it:

Not sure what’s wrong today but I am not able to rank one of my new articles, I have several articles on that news topic and in past they ranked on first page in just 2-3 hours after publishing. Its been 17 hours since I published the 700 words article and I cannot see it anywhere! All old articles.

We are seeing quite wild swings across all sites. I know there are quite a lot of these predictions around here these days, and yes i do appreciate that updates are happening almost all the time (thank you very much) but this does look like some sort of “larger than a normal day” type update.

I am seeing some huge SERP fluctuations today for Google UK. For all of the many brand keywords which I used to rank top 10 for I am now pushed to 2nd or 3rd page.

I checked the Google tracking tools and some of them are showing big swings as well, not all but tools like Mozcast and Accuranker are showing huge swings, while others show small changes or none. Here are the graphs from all of them this morning:
Mozcast:

Sorry, temps for today and yesterday are mostly due to a glitch. We’re fixing the feature data now, but temps will take a day.
