Google October 2015 Algorithm Update?

[Silkstream]

According to Accuranker (https://www.accuranker.com/blog/google-october-2015-algorithm-update/), "Google has made some big changes to their algorithm".

Other than that one article, I haven't noticed or even heard of any considerable fluctuations. Even Mozcast is looking pretty normal today.

Has anyone noticed anything or have any other sources on this? If so, any ideas on what this update seems to be targeting?

The only other mention I can see of this is at rankranger where they are discussing the recent Hacked Sites Algorithm where there is also a distinct Rank Risk indicator for Oct 20th.

Can't see any affect on any of our sites at the moment, one to keep an eye on maybe.

We've seen two spikes in October, but neither one is clear or particularly off-the-charts. There's some evidence that the second "update" may have partially reversed the first one.

I've dug into data around the "Hacked Sites" algorithm, and the signals Google is claiming aren't evident yet. I can't find any unexplained SERPs with a drop in total results, and there's no clear movement on spammy keywords. Google has been unclear about the roll-out date and timeline on this one, and it seems like it might be a long roll-out.

Just as an update to where we was with this I have seen this article this morning where many others are seeing significant activity around the 20th 21st but still doesn't appear to be clear what is causing this.

Still it is an interesting read and update.
