Analysis and Findings From The September 2015 Google Algorithm Updates (9/2 and 9/16): Panda 4.2 Tremors, Manual Updates, The Methode Philosophy, and More

September 2015 Google Updates

In my last post, I explained what I have seen during the extended rollout of Panda 4.2. I ended up analyzing over seven weeks of Panda data, since P4.2 is going through an extended rollout. And yes, it’s still rolling out now. More about that soon. Overall, it had been very quiet leading up to that post. Sure, there were some sites that had seen impact and movement, but not like typical Panda updates. It was an underwhelming update to say the least.

Well, something has changed and more significant tremors have been seen across the web.

It’s hard to say if what I’ve been seeing is Panda or a tweak to Google’s core ranking algorithm, but September has been an extremely volatile month algorithm-wise. Specifically, there was movement on 9/2 with some sites seeing large drops in Google organic traffic. And then there was significant movement on 9/16 where some sites surged in traffic, while others dropped heavily.

For example, here’s a site that dropped on 9/16:

And here’s a site that surged:

Surge During September 16 Google Update

Now, Google pushes hundreds of updates per year, with over one thousand last year according to John Mueller. But the September tremors seem to impact sites with both Panda and Phantom baggage. I’ll cover more about that in this post, but to me it seems like the tremors we have seen are tied to content quality. And again, we have two quality cowboys in town now with Phantom (AKA The Quality Update) and Panda. I definitely saw some sites that got hit hard by Phantom jump during the 9/16 update.

So it’s hard to say it was one over the other. And like I said in my post about Phantom, maybe that was the beginning of Panda being baked into Google’s core ranking algorithm. In other words, they might not be so different…

In this post I’ll cover more about what I’ve seen in September, what Googlers have said about Panda 4.2, I’ll explain more about the connection of these latest updates to Panda and Phantom, and I’ll touch on what I’m calling “The Methode Philosophy”, which is a possible change in how Google views Panda. Let’s jump in.

Confirmed: Panda 4.2 Still Rolling Out & Will For Months
Panda 4.2 started rolling out on 7/18/15 and we knew it would be an extended rollout that could take months. But nobody knew how long that extended rollout would last. Is it still rolling out, has it completed already, and how long before the update completes? All good questions that needed to be answered.

Well, at SMX East Google’s Gary Illyes explained that Panda 4.2 is indeed still rolling out. He last checked on 9/30 and Panda 4.2 was still roaming the web. In addition, he said it will continue to roll out for the next few months. Yes, read that again. Panda 4.2 could have a six month rollout (or longer). As you can imagine, that’s a huge change from previous updates.

Panda 4.2 is still rolling out.

Panda 4.2: Manually Pushed Or Auto-Rollout?
Another question about Panda 4.2 revolves around how it’s being released. Was a giant red button pushed on 7/18 and then P4.2 began its long and extended rollout? Or is Google manually pushing Panda at intervals during the extended rollout. There’s an important distinction between the two.

If Google is pushing the updates manually, then they can refine and tweak the algo based on what they are seeing in the SERPs (to ensure optimal results). That’s similar to what I saw with Panda 4.0 tremors, which was clarified by John Mueller. He said that after a large update, Google can and will tweak that algo to ensure everything is working they way they need it to.

{Updated based on clarification from Gary Illyes:}
So I decided to ask Google’s Gary Illyes on Twitter. At first, Gary explained that Panda 4.2 was being manually pushed at various intervals. But that’s actually not correct. He misunderstood the tweet and didn’t mean that Panda was being pushed manually at various intervals. Instead, Gary explained that Panda 4.2 was manually pushed on 7/18/15 and then automatically rolls out over months. From what he said, there have been no refinements to Panda 4.2 since the initial rollout. That’s important to understand, since it can help us better understand what we are seeing now volatility-wise. And a big thank you to Barry Schwartz for questioning the original response. Without that, I think we would still think Panda 4.2 was being manually pushed.

Both twitter conversations are below. First, here’s my question from yesterday.

Gary Illyes confirms manual Panda 4.2 rollout.
And here’s the clarification from Gary this morning:

September Volatility – 9/2 and 9/16 To Be Specific
I’m sure you’re wondering what type of volatility I’ve seen in September and how that manifested itself in Google rankings and traffic. Below, I’ll provide some screenshots of what I’ve seen across websites, categories, and countries. I’ll focus on September 16 and highlight any connections I’ve seen with previous Panda and/or Phantom impact.

Ups and Downs During September Google Updates

The September Updates Seemed To Target Content Quality (Again)
When analyzing the drop in traffic across sites impacted by the 9/2 and 9/16 updates, I saw a number of familiar problems from a content quality standpoint. These are problems I’ve seen many times while helping companies with Panda and/or Phantom hits. Although some of the sites impacted had historical link problems, not all sites impacted had link issues. But they all had content quality problems.

User Happiness FTW
If you’ve read my previous posts about Panda or Phantom, then you know user happiness is extremely important. If you frustrate or anger users, then you can send them fleeing from your site. During my analysis of the September 2 and September 16 updates, I saw pages that dropped in rankings that provided horrible user experiences. For example, heavy ads scattered throughout the page, forced pagination (for monetization purposes), low quality supplemental content, and more. Let’s explore several of the problems below. Note, if you’ve been following Panda over the years, these problems should not surprise you.

Slideshows or Paginated Content with Keyword Content Not Visible On-Load
I saw several examples of pages that dropped out for keywords when those keywords were not visible on-load. For example, imagine searching for a topic, clicking a result in the search results, landing on a slideshow or paginated article, and not seeing the keywords or topic visible.

This could result in a number of problems SEO-wise. The most important being users getting frustrated and jumping back to the search results since they can’t easily find the content they searched for. Remember, low dwell time is a giant invitation to Panda. Also, John Mueller has said many times that hidden content will either be heavily discounted or not indexed at all. So if one doesn’t get you, the other will. What’s interesting is that pages which used to rank highly for queries related to keywords searched for dropped during the 9/16 update.

September 16 Update Pagination Issues

Thin Pages, Yet Hiding Content
This was a strange one, and it somewhat relates to the bullet above. I found pages that were inherently thin (given the niche), yet the company still chose to force a user to trigger additional content (versus providing it on-load). I have no idea why they would do this on an already thin page, but they did. And I saw those pages drop. It’s worth noting several of those sites also saw drops during the Quality Update (Phantom) in early May of 2015.

September 16 Update and Thin Content

Technical Problems Causing Content Problems (or Ad Problems)
There were a few sites that saw substantial impact during the 9/16 update based on technical problems causing content and/or ad problems. For example, one site built using AngularJS using html snapshots ended up having a giant ad plastered across its content (the snapshot that Google indexes).

Thousands of pages were impacted. On 9/16 they lost approximately 40% of their Google organic search traffic. I can’t say 100% that the drop was due to the ad issue, but it sure looks that way. It’s a leading site in its niche with thorough and detailed content. Although I haven’t analyzed the entire site, having your html snapshots polluted by a giant ad is not good. Not good at all actually.

September 16 Update and Ad Problems

Indexed Bulk Thin Content
A large-scale website with 60M+ pages indexed ended up having over 1M ultra-thin, lower quality pages crawled and indexed (by accident). The business owner already nuked those pages, but they have been on the site for a while. This is also a site that typically sees movement with Panda updates based on its niche, size, and complexity. This is a solid example of “bamboo creep” that can occur without showing any major signs. Then boom, it catches up to you very quickly.

September 16 Update and Bulk Thin Content

Simple, 1997-like Design… INCREASED
I have to explain one jump I saw, since it shocked me at first. The site surged during the 9/16 update, so I dug into the increase in rankings and traffic. When I first visited the site, I almost fell out of my seat. It was so simple, so plain, and so 1997-like, that I couldn’t believe the traffic numbers and strong rankings across competitive keywords.

Simple and Plain Design Surges During September 16 Update

But I picked myself up off the ground and took some time going through the site. It didn’t take long to understand why this site ranked well. It provides granular details for a specific niche, it’s well-documented, and up-to-date. So I reviewed a number of important queries for the site and put myself in the shoes of someone searching for that information. And when I did, I was actually quite happy with the site. It was easy to find the information I wanted, it was organized well (even if it was extremely vanilla), and I found what I wanted quickly.

Remember the first bullet from above? User happiness FTW. :)

Are Bi-Weekly Tremors The New “Quality” Release Schedule?
So, we had an update on Wednesday 9/2 and then another exactly two weeks later on Wednesday 9/16. That sounds a little too perfect, doesn’t it? Based on what we’ve seen, does this mean that Google is tweaking Panda 4.2 and pushing smaller updates every two weeks? Gary says no, so it doesn’t seem like that would be Panda. But it could be Panda 4.2 continuing its rollout. It’s just interesting to see very little impact from P4.2 turn into serious turbulence in early September. And then exactly two weeks later, we saw more turbulence targeting content quality.

That’s speculation, but the updates are similar to the “tremors” I saw after Panda 4.0 (as explained earlier). And by the way, if that bi-weekly schedule is remotely correct, then we should have another tremor any day now. I guess we’ll see.

The Methode Philosophy – A Change In Panda Thinking
Before ending this post, I wanted to bring up an important point based on a video I watched with Google’s Gary Illyes. And I believe it’s a change in Panda philosophy by Google. Specifically, Gary explained that many wrongly believe Panda is about hurting or penalizing a website. He says it’s not. Instead, it’s about ensuring Google “adjusts” websites that become overly prominent for keywords that they shouldn’t rank for. Google wants its users to find the best content possible for the query at hand. So Panda is about making sure websites do not become overly prominent for keywords they shouldn’t rank for. You can watch him explain this in a Q&A with Bruce Clay (at 8:04 in the video).

The Methode Philosophy

Now, I totally understand that, and I actually think it’s great. But that’s not how Panda worked in the past. It didn’t just demote pages on an impacted domain for keywords they shouldn’t rank for. Sure, that was part of it, but it crushed websites overall. For example, sites dropped by 60%+ overnight and it wasn’t just overly generic keywords that site shouldn’t rank for. It included core keywords that the site should rank for. That’s why many viewed Panda as an algorithmic penalty.

The reason I bring this up is because Gary’s comments lead me to think that Panda could have changed… and maybe that’s why we are seeing different results from 4.2 than we typically see. Panda 4.2 is supposed to be a refresh. But what if it’s something different? What if it now works based on how Gary explained it?

Again, I like the approach and I think most SEOs would be on board. But I’m concerned for websites that were hit by Panda 4.1 on September 23, 2014 or by the October 24, 2014 update. Many of those websites are still struggling to recover, even after making significant changes. And if Panda has fundamentally changed, then those sites may never recover. They would be in Panda limbo with little hope of coming back, and that would be wrong. It’s hard to say if this is happening, but it’s worth noting.

As The Panda Turns – The Future For Panda and Phantom Victims
After speaking with many webmasters that have been impacted by Panda and/or Phantom, many feel as if they are currently in a horror movie (which fits since Halloween is right around the corner). You know, like being stranded in an abandoned sleep away camp in the woods, knowing a killer could strike at any time, hoping they are spared during the next attack, and trying to send an SOS to local law enforcement. But they just can’t seem to get out of Camp Crystal Lake. Yes, it’s like Friday the 13th, but for SEOs. Just swap Jason for Panda and make it a 6 month movie versus 2 hours. :)

That said, I’m actually hopeful given the volatile September we just experienced. Frequent updates can be good, as more sites can see impact (and hopefully up with the down). Let’s face it, would you rather have 10 months of inactivity or frequent updates? I’m for the latter.

Moving forward, it’s always smart to clean up any problems your site has (both on-site and off-site). This is the same advice I’ve been giving since before Panda 4.2 rolled out and I still believe tackling all quality problems is a smart way to proceed. In a nutshell, you should be ready for more tremors, for Panda 4.3 (if that’s coming), or for the real-time Panda (which we know Google wants to roll out).

That’s all you can do at this point. And of course, you could sip a witches’ brew with a bamboo garnish while trick or treating. But watch out for that Jason Voorhees guy. I heard he’s dressing up as a panda this year. Good luck.  :)

  1. If a site did not show any signs of recovery, is it possible that Panda 4.2 hasn’t yet processed that site? At least with the old Panda updates, you knew where you stood. With this latest iteration, Google has once again succeeded in confusing site owners.

    • Great question. There are definitely still sites that have done a lot of work to improve based on past Panda hits that have seen very little movement. It’s hard to say if that’s because they technically haven’t recovered from Panda or if Panda has changed (see the section of my post about The Methode Philosophy. It’s been a very strange update for sure with the extended rollout, the September tremors, its connection with Phantom, etc. I hope that helps.

  2. Since Panda 4.2 is not being tweaked, is the data set they are using still from some earlier in the year? I remember Barry asking about this back in early summer when he reported that Panda was going to roll out soon, and the question was asked if it was to late to try to make any changes to your website? And I think Gary or JohnMu said it was too late. My concern is that sites can change a lot in 6 months, so it doesn’t make sense if they release Panda 4.2 over 1/2 a year, and not refresh the data set they are using? If they don’t update the data, are we doomed forever?

    • Great question Sabita. I think we are hearing conflicting messages. Google says they pushed the Panda 4.2 button in July and then didn’t touch the algo since, yet I’ve heard John Mueller explain that you should keep improving quality as they can pick up those changes (even after P4.2 rolled out). But, will other quality algos pick up those changes, or can Panda 4.2 use that new data? I’m not sure anyone has commented on that. I’ll try and reach out to Google and see if we can get a clarification. Stay tuned.

      • Panda is a frustrating subject but thank you for this very informative post. My site was hit like many others in September of 2014. Since that time, we have made a ton of changes design and content wise. We are confident that our site is better in the eyes of Google, and more importantly our users.

        Regarding continuing to update and improve our sites. I agree 100 percent we should always be doing that. My site has even seen some improvements from what I suspect was a few of the “hundreds of different Google algorithm factors.” The improvements are small and marginal though, and we are still filtered for the majority of keywords that we should be ranking for.

        The problem is, as you know, Panda is like driving with the emergency brake on in a car with four flat tires. We can add all of the great content (a larger engine) and earn editorial backlinks (high performance turbo chargers) we want. While our speed will improve from maybe 3 mph to 5 mph with increases form Phantom and other algos, Panda will always weigh us down significantly. With the lack of updates and the “long rollout,” it feels like every automative shop with those new tires is sold out. And the emergency brake just happens to be stuck, but if we keep trying, it may go down one day.

        It is really a devastating penalty (I know Google says it isn’t a penalty, but if it looks like a duck, swims like a duck, and quacks like a duck, then it probably is a duck).

        One of the Google spokespeople even had the nerve to say Panda is designed to only prevent you from ranking for terms that you shouldn’t rank for. I am guessing this means really long tail keywords. But we all know Panda filters sites for way more keywords than that. It is a penalty and a devastating one with way too long a jail sentence.

        I really fear that Google has no idea what they are doing with Panda anymore, and sites that were hit in the fall of 2014 will be trapped forever, which is absolutely disgusting and embarrassing coming from Google.

        At this point, do you feel as though Panda hit site owners should start over with new sites? While this sounds drastic, chasing Google for a recovery that may never come could be much more damaging in the long run.

        I just wish Google would clarify and give people an idea on if Panda recoveries are even possible, because they seem to be very few and far between.

  3. Panda is a disaster. Gary keeps talking about the long rollout like it’s a good thing. I don’t understand how using data from June for this update is helpful at all. They need to do a normal refresh. Otherwise, Panda is basically a new Way Back Machine ( showing the results on how the Internet was a half a year ago. Pretty pathetic coming from Google.

    • Definitely agree that it would be optimal to use fresh data for Panda 4.2 as it rolls out. See my reply to Sabita below about getting some clarification on the subject. I’ll try and find out more soon.

  4. Great points, and I definitely agree that if Panda has fundamentally changed, then it’s not fair for those negatively impacted on 9/23 or 10/24/14. The one thing I can say is that the recent spike in activity algo-wise is a good thing. I’d much rather see that than waiting 10 months for the next update. We had 9/2, 9/16 and it does look like there was another update around 10/1. That follows the bi-weekly updates I mentioned above.

    We know that Phantom (AKA The Quality Update) is part of Google’s core ranking algorithm, so that’s running all the time. And we also know Google wants to bake Panda into its core ranking algo. It’s hard to say when that will happen, but I do believe it will at some point.

    Regarding un-penalizing sites, that’s not going to happen (in my opinion). There’s a case to do that for Penguin as well, but that hasn’t happened either. I haven’t analyzed your site, but I would keep working to enhance content, create new killer content, remove ad problems, increase engagement, remove technical issues, etc. That’s the best way to recover from a quality update like Panda or Phantom. I hope that helps.
