Penguinflux or Hummingbird?

Today we upgraded Algoroo to include all available SERP flux data ranging from December 2012 until now. One thing that strikes me as unusual is the impact Penguin 2.0 left on search results. It seems that the level of search result volatility never restored to its pre-Penguin 2.0 state which hints at a possibility of a whole new real-time search quality algorithm. Google has already confirmed that Panda (which used to be released manually) now runs continuously. I don’t have any records of Penguinlux being confirmed by Google but if you take a look at the graph below it’s clear that their results are much more turbulent since 23rd of May this year.

An update on this article was brought to my attention:

After contacting Google’s press department I was informed that Google has been running Hummingbird “for a few months,” not just since last month. The press department also reiterated their guidance for those doing SEO, “Our guidance to webmasters is the same as always — we encourage original, high-quality content, since that’s what’s best for web users.”

If the above is true, and Hummingbird was also such a dramatic algo update at Google, than the only date I can attribute it to is the 6th of June, though that seems pretty far from now. Still, we see a huge spike right after Penguin and no other update was assigned to this date.

I’m keen to hear your thoughts or any further updates you may have from official sources (Google).
