The November 8, 2019 Google update may have been a link related update

Google has been much better lately at informing the SEO community about large algorithm updates. On November 8, 2019, however, Google appears to have pushed out a significant update. They have said nothing about this update other than these tweets:

GSL several updates in november tweet

GSL tweet part 2

GSL tweet part 3

GSL tweet part 4

What can we learn from these tweets? Here is our interpretation:

  • Google ran several updates last week. But then, they are always running updates. Some are more impactful than others.
  • The fact that Google didn’t share about this update means it may be possible that there is no means of recovery if you were hit. (We’ll discuss this more later in this article.)
  • Google ended these tweets by referring to their blog post on core updates. This blog post discusses Google’s guidelines and has a heavy focus on E-A-T. The question though, is whether this current update was a core update or not.

Since publishing this, we have had several people comment that they saw large drops in organic traffic and have never been involved in link building at all. If you feel you have been unfairly hit by this update, we would love if you could share your url with us so we can investigate further. These will be kept completely anonymous. Unfortunately, we cannot individually respond to everyone who shares but we will update this post if we can draw more conclusions about what Google was doing with this update.


Early thoughts on what happened November 8

We often joke that Google tends to run major updates when I, Marie am traveling. I’m sure that this is not the case...it’s probably just coincidental as I travel a lot! While I was not away this weekend, I did actually take the weekend completely off, without even checking in on Twitter. On Monday morning, I saw many tweets and mentions from people who had suffered massive drops in Google organic traffic over the weekend. We also had a large influx of requests come through our contact form from businesses who had very large traffic drops and were looking for help.

In this article, I will share with you our early thoughts on what is going on with this update. Most of our client base saw very little change in rankings and traffic beyond what is expected for the season. However, for those who did see changes in traffic, we found some very interesting correlations. 


Please know that this article contains a lot of theory. We do feel strongly that this update is closely tied to link quality, but we do not know this for sure. There is also a possibility that thin content could play a role. We will update this article as more information becomes available.


As with any significant update, my team and I have gathered information from many sources to find examples of sites that were affected either positively or negatively at this time. We look at our own client base of hundreds of sites, our intake emails, Twitter, several help forums, Search Engine Roundtable and other sources. Something that we noticed is that of the sites that saw declines this weekend, there were quite a few sites from the following industries or categories:

  • recipe bloggers
  • affiliate sites
  • travel sites
  • aggregator / directory sites

Link issues

Almost every site that we looked at that saw drops had issues with unnatural links pointing to their site. At first we wondered if the data was skewed, as we do have a lot of clients that originally came to us because they potentially needed disavow work. But, we do not think this is the case.

Here is one site that we filed a thorough disavow for just over a year ago. We did no other work for this site other than a link by link audit. We filed a disavow with hundreds of domains in it, many of which contained links in articles that were very clearly made for SEO purposes alone. They have been seeing incredible improvements since then and then dropped significantly on November 8:

In looking at these links, many were the same type we previously had disavowed. It looks like this site may be experimenting with purchasing Private Blog Network links. If so, it’s not working well for them!

Another site that we recently reviewed is seeing a 35% drop in Google organic traffic. In the links section of their site quality review, we wrote that we had “serious concerns with the quality of [their] link profile”. They had loads of in-article links that were definitely there just for SEO reasons.

There were several other sites with a similar pattern as well. 

We then looked at our clients who had seen improvements over the weekend. We had several sites seeing increases on November 8, 2019. Here are a couple for which we have permission to share:

client 1 increase

client 2 increase

Please know, however, that it is really early to say whether these increases were solely due to an algorithm update. We’ll need more time to say that for certain.

None of our clients who saw nice improvements were ones for whom we had recommended a thorough link by link audit. It is interesting to note that some were sites for which we had recommended trimming out a large amount of thin content. We’ll note this but given that some of the sites that saw improvements have not yet cleared out thin content, we feel that this is likely coincidental rather than a cause for their gains.

We feel very strongly that this is a link related update. It could have other components, but links are likely very important!

Our current theories on what Google changed on November 8, 2019

Keep in mind that at the time of writing this, less than a week has passed since this update happened. We will hopefully have more data soon and will update this post if our theories change.


It is possible that Google has gotten better at figuring out which types of links to count as mentions. 


Most of the sites that saw drops in traffic had links that most of us would likely call, “grey hat” and some of the SEO community (although not us), could even consider “white hat”. These are links that for the most part aren’t illegal or even unethical, but really don’t truly represent natural mentions. Here are some examples of the types of links that we feel used to work to help sites, but may no longer do so as of November 8, 2019.

Footer Links

Many of the sites that saw drops were web design sites or other similar sites that have links from their clients’ footers. An example would be a site that makes websites and includes a footer link on each of their clients’ sites saying, “Web Design by ABC Websites”. 

It is interesting to note that Google made changes to their guide on link schemes to add the following (the bolded part is new):

Requiring a link as part of a Terms of Service, contract, or similar arrangement without allowing a third-party content owner the choice of qualifying the outbound link, should they wish.”

This used to say, “Requiring a link as part of a Terms of Service, contract, or similar arrangement without allowing a third-party content owner the choice of using nofollow or other methods of blocking PageRank, should they wish.”

“Qualifying the outbound link” links to Google’s page describing rel=nofollowed, rel=sponsored and rel=ugc. We believe that the point they are saying here is that if you are getting links because it’s a requirement of using your product, then those truly are not natural mentions or recommendations of your website. If you provide customers with a web template and a requirement for them to use it is to include a footer link back to you, this goes against Google’s guidelines. Links like this should be either nofollowed or should use rel=sponsored. Either is fine to use. 

Examples of this could include a web design company that includes a link in each of their designs that points back to their site, or perhaps a directory that will give you a higher placement on their website if you link back to them.

Although this is a few years old, we have good information here on footer links and SEO.

Reciprocal blogger links

We feel that one of the reasons why many recipe sites saw a decline in traffic could be that they were previously benefitting from link schemes. We saw that many of the recipe sites who saw drops, had a lot of links that look like this:

recipe site 1 links

recipe site 2 links

We’re not saying that these are necessarily unnatural! If you have a recipe blog and other recipe bloggers truly want to recommend your website, this is great. However, for some of the recipe sites that saw drops, we saw enough of this type of link that we feel there was potentially a pattern of manipulation. Even if these links are not all reciprocal links, we feel that these links could be the type of link Google talks about in their link quality guide, where they mention, “Excessive link exchanges ("Link to me and I'll link to you") or partner pages exclusively for the sake of cross-linking.” 

If you are a blogger who is involved in a program whereby you regularly link out to other bloggers and in turn, they include links to you, then these links may have helped in the past. The question now is whether these links are actually hurting sites or whether Google is simply recognizing them as manufactured votes for your site and just discounting them.

Please know that it is perfectly acceptable in Google’s eyes to ask other people for a link. It’s the scale and also the intent to manipulate rankings that is the main concern.

Top x lists

Several of the sites that we reviewed that saw drops seemed to have a disproportionate number of links from top 10 lists. We see this a lot in link audits and often struggle when we are determining whether these are actually natural links.

Take for example, an article on an authoritative site that is called, “The Top 10 Salon Software Products”, or “Here are 8 amazing pumpkin pie recipes”, or “Traveling to India? Here are the best travel blogs”.

When we see a site that has a large number of links in lists like this we start to wonder how those links were obtained. On one hand, your site may truly be one of the best of its kind and it may get mentioned a lot. We’ve been mentioned in several posts that talk about the best SEO blogs. (Thank you!) And we certainly did not pay for any of those. 

But, in some cases, the way you get on these “top x” lists is to pay for inclusion. We think it is possible that Google recognized that many of these links are not truly votes for your site. We’re not as confident on this point just yet though, as we are with the above theories.

In-article links and PBNs and possibly some guest posting

Google’s link scheme guide has always recommended against, “exchanging money for links, or posts that contain links”. Links from Private Blog Networks (i.e. a network of websites that are only set up to be able to link out via articles) and articles that were written solely for SEO have been considered unnatural by Google for years now. 

We do think it is possible that Google has now gotten better at determining which links from articles are truly mentions of your site and which are there simply for the PageRank. 

We have seen several reports of Blackhats complaining that their PBNs stopped working for them with this update. 

Is the November 2019 Google update connected to BERT?

Given that Google recently announced they are now using BERT to better understand queries, we did spend some time theorizing that perhaps this update could be connected to BERT. At this point, this theory is a little weak. The idea is that it is possible that BERT allows Google to do a much better job at understanding the content on a page. Let’s say that these are two competing pages:

1) A recipe page that is relatively good and is linked to from many recipe bloggers.

2) A recipe page that is REALLY good but does not have a lot of links.

In the past, the first page would be much more likely to rank as it has links from many bloggers. But, what if Google’s newfound ability to better understand language allows them to determine that the content on page 2 truly is better? This could mean that it starts to outrank page 1 even without links. 

Or, in other words, page 1 may have previously ranked well on the power of links, but now that Google can better assess page quality, those links to page 1 are no longer as important in Google’s ranking decisions.

We’ll keep this theory in mind going forward, but at this point we really do think that this update was mostly about Google’s ability to detect which links are true mentions for your site.

Should you disavow if you were affected by this update?

If you have been building links with any of these tactics, we do think that a thorough link audit and disavow could help. What we don’t know, however, is whether Google is simply discounting links that they can now detect as not true recommendations for your site, or whether having enough of these could actually be suppressing the site’s ability to rank.

John Mueller has mentioned that if a site has enough unnatural links, it can indeed hurt them, even if the site does not have a manual action. When asked whether unnatural links could hurt a site algorithmically, John said:

That can definitely be the case. So it’s something where our algorithms when we look at it and they see, oh, there are a bunch of really bad links here. Then maybe they’ll be a bit more cautious with regards to the links in general for the website. So if you clean that up, then the algorithms look at it and say, oh, there’s– there’s kind of– it’s OK. It’s not bad.” 

Keep in mind that it is still early and we have much more analysis to do. We will be monitoring the fallout from this update and will report back if our theories change. To stay up to date with our thoughts on this and also future updates, you can subscribe to our newsletter.
