Summary: Yes, it’s happening again. There was a significant Google algorithm update on 11/30/16, following an update on 11/10/16 that was partially reversed on 11/18/16. And the 11/30 update is showing a connection to previous quality updates (AKA Phantom). Let’s explore what’s going on in Google Land.

November 30, 2016 Google Algorithm Update

When writing about the November 10, 2016 Google algorithm update, I mentioned this has been one of the most volatile falls I’ve seen from an algo update perspective. Well, now we are nearing winter, and the volatility hasn’t calmed down! I picked up a substantial algorithm update starting on November 30, 2016, with many sites seeing significant movement (both up and down). Some sites absolutely surged, while others tanked.

But to make matters even more complicated, I’m now seeing partial reversals starting on December 13, 2016. So just like the November 10 update, there are some sites reverting back to their pre-November 30 levels. It’s important to note that not all sites are reverting. Some have stayed at their new levels, while others have either surged more or dropped more.

Yes, it’s even a crazier time in Google Land, which is saying a lot given the amount of changes Google pushes out on a regular basis. Remember, there are hundreds of updates rolling out each year, but only some are significant. Those are the updates I typically cover here. For example, the June 29, 2016 update, November 10, 2016 update, etc.

Significant movement on 11/30. It was BIG.
On 11/30 I started to see movement across a number of sites I have access to. I saw some sites start to jump up, while others saw downward movement. In addition, I had a number of companies reach out to me after seeing substantial movement (both up and down). For example, here are two examples (and the second has ties to the 11/18 update):

Huge Drop During 11/30/16 Google Algorithm Update

Reverse the engines! Partial reversal on 12/13 (again)…
{Update: December 15 – SEMrush database update impacting 12/13 numbers}
I reached out to SEMrush about some of the severe spikes I was seeing starting on 12/13 and they got back to me this morning. There was a database update that could be causing some large spikes on certain sites. That doesn’t impact the 11/30 or 12/8 trending, but it is impacting the extreme spikes seen on 12/13. Note, I’m still seeing movement on some sites impacted by the 11/30 update during the 12/13 and 12/14 timeframe, but not as extreme as what SEMrush was showing. And now Barry Schwartz is reporting a possible update on 12/15. Like I said earlier, this is one of the most volatile few months from an algorithm update standpoint I’ve ever seen.
————————————————–

Now, just like I saw with the 11/10 update, I am seeing some sites reverse course starting on 12/13. That’s exactly what I saw with the 11/10 update with some sites reversing course on 11/18. It was fascinating (and crazy) to see that happen, but it’s happening again.

For example, here are a few reversals:
Reversal of 11/30 update with surge on 12/13.

Reversal of 11/30 update on 12/13.

Reversal of 11/30 update on 12/13.

But again, some sites are seeing further gains or continued drops starting on 12/13. Here is one seeing an increase on 11/30 with a surge on 12/13:

Increasing during each Google algo update starting on 11/30/16.

One thing is for sure. Google is either testing like mad, or they are having a very tough time with the algo update. Or maybe it’s both. Again, welcome to Google Land. :)

Connections to the November 18 rollback:
When analyzing sites seeing impact, it was easy to see that some had a connection with the 11/18 update. This leads me to think that Google has been refining whatever they rolled out on November 10. I can’t say for sure that’s what is going on but it sure makes sense. Again, some sites saw a complete reversal of the impact from 11/10 on 11/18. Again, that leads me to believe Google was either testing the mobile-first index or there were flaws in the algo.

Connection between November 18 update and November 30 update.

And if you think Google wouldn’t roll out a flawed algo, then go read my post about the movie blog fiasco from 2014. The entire algo update was rolled back 10 days later. All of the sites that got pummeled reversed course. Here’s an example of one site that was impacted back in 2014:

Movie blog fiasco in February of 2014.

What I’m seeing. Impact from the 11/30 update:
Mobile problems again…
In my post about the 11/10 update, I wrote that Google could have been testing the mobile-first index. I saw many mobile problems while analyzing sites impacted by the update, and the timing made complete sense. Just a few days before that update, Google wrote a post about the mobile-first index and explained they were testing it in the wild. The update on 11/10 (or at least part of it), could have been the mobile-first index in action.

Now I’m seeing similar things while analyzing sites impacted by the 11/30 update. That includes mobile popups, interstitials, mobile UIs breaking, and other horrible mobile UX problems. I can’t say for sure if we’re seeing another test of the mobile-first index in action, but we very well could be.

Here’s one of my favorites from analyzing this update:
Horrible mobile popup on site impacted by 11/30 Google algorithm update.

Low-quality user engagement problems (Phantom):
Beyond just mobile problems, I saw many of the usual suspects from a Phantom standpoint. If you’re not familiar with Phantom, then read my two-parts series about Google’s quality updates on Search Engine Land.

I saw many “low quality user engagement” problems while analyzing the 11/30 update. That included ads weaved into content, broken UIs, aggressive monetization (in several forms), and more. For some sites, it was hard to distinguish the real content from the ads. I mistakenly clicked a few ads and was whisked downstream to advertiser sites several times. And some of those sites were overly aggressive with their own tactics. Again, that’s a double-whammy from a user experience standpoint.

Like I’ve said repeatedly about Phantom, hell hath no fury like a user scorned.

What You Can Do:
If you were impacted by the November 30 update, I highly recommend:

  • Heavily reviewing your mobile setup to ensure you are providing the same content that you are on desktop. Remember, the mobile-first index will use the mobile page for ranking purposes. So make sure you are providing the full content via mobile.
  • Also, ensure your mobile setup provides the best user experience possible. For example, don’t use mobile popups or interstitials, don’t weave giant ads into your mobile content that heavily impact the user experience, don’t have broken mobile UIs, etc. Beyond the mobile-first index, Google will be rolling out its mobile popup algorithm on 1/10/17. Beware.
  • And beyond mobile, I would analyze your site through the lens of Google’s quality updates (AKA Phantom). Look for barriers that could be inhibiting the user experience, check for aggressive monetization, weaved ads in content, broken UIs, check fetch and render to ensure Google can see all of your content, and more. You can read my previous posts about Phantom to learn more about what I’ve uncovered.

Summary – The Crazy Fall of Algo Updates Continues… Stay Tuned.
Again this is a developing story, and I’ll try to update this post with more information as I analyze more sites impacted by the November 30, 2016 update (and the reversals I’m seeing that started on December 13, 2016.)

As I mentioned earlier, the fall of 2016 has been one of the most volatile I have seen. And the volatility continues with the 11/30/16 update (and partial reversals on 12/13/16). I recommend checking your stats as soon as possible to see if you’ve been impacted. And if you have, follow the recommendations I provided above (and in my other posts about Google’s algo updates). That’s how you can surface potential problems causing the drop. Again, I’ll try to update this post with more information soon.

    • Hey, glad my post was helpful. Just wondering, did you see any volatility during the 11/10 and 11/18 updates? I’m seeing a connection with some sites impacted by the 11/30 and 12/13 updates.

  1. Please to read of that change on 11/30. We had a version update on that day and I could not see any on page reason for a traffic loss!
    Now I see it, unfortunately I did not see any recuperacion yesterday :-(

    • OK, so you saw impact on 11/30, but didn’t see any impact on 12/13? I’ve seen sites with similar trending. Some sites reversed on 12/13 while others surged more (or dropped more). I’m not sure we’re done yet btw. I’ll be monitoring the situation closely.

  2. Hey Glenn, see my screenshot here. Our site seems to be getting pounded here on every update interval except 11/10. We are frantically removing/correcting every potential issue hoping that they release our site before this series of updates ends, but I am not feeling very confident! I suspect that quality issues are not so easily reversed since they need time to evaluate a site. I suspect it was our popups and ads that nailed us to the floor :(

    • I’m sorry to hear you’ve seen negative impact! Note, I’m definitely seeing a stronger connection to previous Phantom updates. Were you impacted by a previous quality update? I believe you’ve been auditing your site through the lens of Phantom, so that’s definitely a good idea.

  3. I saw one website get killed in the SERPs in September, then spike on up on 11/30, drop 12/1 completely die on 12/6 spike up 12/7 back down 12/8 up on 12/10 down 12/11 and slight up on 12/13. Been checking different sites and see a lot of the same movements. Thanx for writing it up, can’t wait to see the update post

    • The 12/13 SEMrush data was impacted by a database update. The 11/30 and 12/8 numbers weren’t though. So that latest spike in your screenshot is unfortunately not accurate (from a traffic perspective).

    • Hey, thanks for sharing the screenshot. That’s a clear connection to Phantom 2, to say the least. I was tracking and monitoring the 11/30 update since it hit, but just had time to write about it now. :) Thx again.

    • Right, so the SEMrush data for 12/13 was impacted by a database update, but the data for 11/30 and 12/8 was not. And btw, I’m seeing more connections to Phantom with the 11/30 update. For example, sites previously impacted by other quality updates seeing impact during the 11/30 update.

  4. Hi Glenn,

    Thanks for the article, very insightful.

    Do you think this update could be penalizing websites with Google’s own Adsense for mobile? I’m talking about the page-level ads, mobile only, which include one ad format (vignette) that is in fact an interstitial. It only shows at specific times and only to some users, but… when they appear, it’s a full-screen ad.

    I’m asking because I have a website with vignette ads who saw a decline in organic traffic on 11/30/16. Not a big decline, but certainly noticeable, and still didn’t recover. This site was never impacted (negatively) by any Google update before. Could be the adsense?

    Thanks for your time!

    • I’m sorry to hear your site was negatively impacted on 11/30! It was a big update. Regarding vignette ads via AdSense, those are supposed to trigger in between pages and not when someone enters the site. https://support.google.com/adsense/answer/6245304?hl=en

      If that’s how they are working, then the mobile popup algo (which hasn’t officially rolled out yet), would not have a problem with that. But there’s a negative user experience issue with those types of ads. And that could send users running back to the SERPs.

      So from that standpoint, those ads could have an impact. It’s hard to say without analyzing the site. It’s also worth noting that there’s typically a battery of problems causing issues (and not just one problem.) So if your site was impacted by a quality update, I would try and surface all possible “low quality user engagement” problems. I hope that helps!

      • Thanks for your answer. I’ll remove the ads for some weeks and see what happens (both on organic traffic and user signals). Meanwhile I’ll be looking for other possible problems too. Thanks again!
