There are increasing reports of significant movements in the SERPs this week (19th November) with some indicating that it may be a Panda Refresh, or only the continued roll-out of Panda (as Google did say it will be rolled out over some months). It is also possible it is just a change in the core algorithm, with content quality being targeted.
That being said, we are still expecting a Penguin Update before the end of the year, which may change to a “real-time” algorithm, but as of yet (and this story is still evolving) there are no reports (complaints by link spammers) that it is Penguin related.
Here is a selection of some of the reports on the Webmasterworld forum:
Seeing really positive Panda movement as of today in the UK. All my websites are making progress. Multiple verticals. - 10:16 a.m. on Nov 19, 2015
I’m seeing a lot of change here in the UK too. Links are king; bought or otherwise (mainly bought). - 3:52 p.m. on Nov 19, 2015
Seen some major dips and spikes on certain keywords on my US and UK websites. Others are just flat! - 5:31 p.m. on Nov 19, 2015
If having thousands of instant links from Chinese blogs is quality then, yes, this is a quality update. I suppose I’ve seen worse Google results before but I can’t remember when. Hopefully this will change when it settles but these spam websites have been around for months so I’m not holding my breath. - 5:37 p.m. on Nov 19, 2015
Seeing positive movement here too - don’t know whether its panda, but I’ve been working on making websites mobile and tablet friendly - upturn is not limited to those platforms. - 6:09 p.m. on Nov 19, 2015
Let’s take a look at the SERP Trackers
SERP trackers provide an invaluable guide to indicate just how many websites are affected by the latest Google Update.
MozCast at the current time only shows data up until 18th November. This indicates that the update started rolling out a little earlier than the web chatter suggests. With an Algo Temperature of 83 degrees, the updates look relatively significant, but we won’t know for sure until a few days.
Rank Risk Index
This SERP tracker shows data for the 19th November, and it mirrors the rise seen in MozCast.
Algoroo shows data up to 20th November. Instead of a spike over one day, the increase in activity seems to be spread out over several, starting on 17th November. This could just be due to the way the data is interpreted.
What did Google have to say about the SERP Volatility?
John Mueller, a webmaster trends analyst at Google, responded to some tweets about the recent volatility. Reading between the lines, it sounds like it was a core algorithm change, rather than Panda or Penguin.
While this story is evolving, and we will update it as we get more information, we suspect that it relates to website quality. This could be either related to Panda, or a change in the core algorithm.
We did notice a temporary uptick in traffic around a week or so ago, and fluctuations were seen in both MozCast and the Rank Risk Index. It is possible they were testing these current changes, or indeed the changes we are now seeing are just a continuation of those tests \ algorithm tweaks.
Editor’s note - 20th November: Google’s John Mueller responded to questions about the update with an indication that it was a core algorithm change. We have updated the article to reflect this new information.
