Google (Core) Updates in June and July 2021: An overview and recommendations

Google (Core) Updates in June and July 2021

Last updated on August 2, 2021

There’s been a lot going on in Google search during the last few weeks – the June 2021 Core Update, the Page Experience Update, two spam updates, the July 2021 Core Update and finally the Link Spam Update. That makes 6 officially confirmed Google updates since the start of June!

If you’ve noticed unusually strong ranking fluctuations from early June until late July, there’s a good chance that i’s related to one or multiple of these updates. To help you keep track of everything that happened during the last weeks, we will provide you with a clear overview in this article and we’ll also explain what you can do if you’ve been hit by one of the updates!

Overview of Google updates during the last weeks

Google released 6 officially confirmed updates since the start of June, including:

  • the June 2021 Core Update (from June 2 to June 12) which was slightly different from the typical core update…
  • the Page Experience Update (from June 15), making Core Web Vitals an official ranking factor
  • two unexpected spam updates (on June 23 and June 28)
  • the July 2021 Core Update (from July 1 to July 12) which is part 2 of the June 2021 Core Update
  • the Link Spam Update (from July 26) that aims to detect spammy backlinks more effectively

Let’s take a closer look at each of these updates.

June 2021 Core Update

After a six-month wait since the last core update in December, Google announced the June 2021 Core Update on June 2. For the first time in the history of core updates, it wasn’t rolled out at once but split into two parts, with the July 2021 Core Update following a month later (more on that below).

Google explained that some parts of the update were not ready to roll out yet, so they were moved to July.

After the official announcement, it took several days until the SEO community noticed the first impact:

But compared to previous updates, the reactions were spread over a longer period of time and the discussions weren’t as intensive as before. This actually makes sense as many SEO data providers found that the June 2021 Core Update took longer to roll out than usual. In the past, the impact of a core update was mostly felt within a shorter time frame.

As with almost every past core update, it was very hard to tell how exactly Google’s algorithm was changed. As the name suggests, a core update includes changes to the broad core of Google’s search engine, instead of adding or adjusting individual ranking factors (as is the case with the page experience update – more on that later).

But it’s still possible to analyze the industries and types of websites that have been targeted most by a core update. Here’s a short summary of the data about the June 2021 Core Update:

  • Searchmetrics found that many directories were among the losers of this update, along with fake-airport sites that seemed to be high-quality sites but actually contained lots of spam. Websites with thin content were also among the losers.
  • Data by Semrush shows that the categories health, autos & vehicles, pets & animals, science, and travel were hit the hardest.
  • This slightly contradicts another analysis by Sistrix which states that YMYL websites (“Your Money, Your Life”, e.g. health and finance topics) were affected below average. Instead, a lot of websites with a regional or local focus (e.g. business directories, city websites, etc.) were among the biggest winners and losers according to their data.

To summarize, the data on the June 2021 Core Update wasn’t as clear and to some parts even contradictory, in contrast to past core updates which were often very similar in terms of the categories and websites impacted.

Due to this different impact and the slow rollout, some SEOs (including us) concluded that Google may have changed the way that core updates are being rolled out. But part 2 of the update in July showed that this trend didn’t continue (at least for now)…

But before we go into more detail on the July update, let’s take a look at the second Google update that started in June.

Page Experience Update

Last year, Google announced that the Page Experience Update should be released in May 2021. After a short-term delay of one month, the rollout started on June 15 and will take until the end of August, according to Google.

With the Page Experience Update, Google’s “Core Web Vitals” are becoming an official ranking factor. Core Web Vitals are real-world performance metrics that Google uses to evaluate a site’s user experience.

In our Core Web Vitals guide, we’ve explained how Google calculates these values and how you can optimize them on your own website.

So let’s move on to the next two updates right away!

Spam updates on June 23 and June 28

Google rolled out both of its spam updates in June within one day – unlike the core updates, which usually take up to two weeks. (Not to mention the Page Experience Update which takes Google more than two months to complete…)

Google didn’t share any details about the type of spam targeted by these updates. Instead, they only shared a general post about how Google was fighting spam in 2020 using artificial intelligence, along with this video:

What is certain, however, is that these are global updates that affected both web pages and images. Google’s goal with the spam updates is to further improve Google Search and make it safer for users. That’s why Google wants to remove spam sites from its search results that spread malware or try to deceive users, for example.

The overall impact of the spam updates seemed to be limited and smaller than with the core updates.

July 2021 Core Update

Google kept its promise and released part 2 of the June core update just in time on July 1.

Unlike the June update, which took a long time to roll out, the effects of the July update were felt almost immediately after the announcement. Most of the changes happened within a single day, while the effects of the June update were spread over a longer period of time. Nevertheless, most of the SEO data providers state that the July 2021 Core Update was the smaller one.

According to Semrush, the categories real estate, shopping, beauty & fitness, science, and pets & animals were hit the hardest in July. Although the latter two were among the most impacted categories in June already, only a small percentage of websites were hit hard by both updates.

According to Sistrix, many YMYL sites were affected, as with previous core updates.

Overall, the July 2021 Core Update seems to match the pattern of past core updates, both in terms of rollout and affected sites. Maybe the June update was only different because it wasn’t a “complete” core update, but just part 1 of 2. Either way, we are curious to see if the core updates will continue as usual in the future, or if there might be a turnaround after all!

Now let’s get to the grand finale of Google’s update series (at least for now)…

Link Spam Update

Google granted us only a few quiet weeks before they continued with the next update on July 26: the Link Spam Update. This update was announced in a post on Google’s Search Central Blog:

“In our continued efforts to improve the quality of the search results, we’re launching a new link spam fighting change today — which we call the “link spam update.” This algorithm update, which will rollout across the next two weeks, is even more effective at identifying and nullifying link spam more broadly, across multiple languages.”

So apparently, Google won’t actively penalize link spam with this update – it’s just not considered for ranking search results. However, the update can have negative effects for websites that profited from black hat link building before this update.

To date (July 30, 2021), no major impact of the update has been noticed and the SEO community has been rather quiet about it. Although there have been fluctuations in search results on July 29, it’s not clear whether they are related to the Link Spam Update. Google itself didn’t share any details about the impact of this update.

What you should do if you were hit

Let’s get to the most important part: What should you do if you think that you’ve been hit by one of the latest updates?

If your rankings changed to an unusual extent during the last few weeks, the first thing you should do is analyze the exact time frame in which this change took place. This way, you’ll hopefully be able to see which update hit you. This is important because you’ll have to focus on different actions for recovery, depending on the update that affected you.

Spam Updates

As far as the spam updates are concerned, you can rest assured: it’s very unlikely that you were penalized by these updates as long as you’re running a legitimate and trustworthy website that complies with Google’s webmaster guidelines (which we assume to be the case 🙂).

You still think that you were affected because you saw heavy ranking losses on June 23 or 28? Then the first thing you should do is make sure that your website is not hacked. Although this is very unlikely, it is a popular scam tactic to spread spam and malware through legitimate websites. Google explains how to determine if your website is hacked here.

If everything is fine and your website is not subject to a cyber-attack, you should check whether it might appear to be spammy at any point. You can find a list of possible reasons why your website may look like spam here. Besides that, we recommend you go through Google’s Webmaster Guidelines and make sure that you don’t violate any of them.

Page Experience Update

To date, there seems to be no measurable impact of the Page Experience Update. This is not surprising, considering that the update is supposed to take until the end of August.

Unfortunately, the slow rollout makes it very difficult to tell if you are affected by the update or not. That’s why you should make sure that you pass Google’s core web vitals in the first place. You can check your core web vitals using Google’s Pagespeed Insights, for example.

Google Pagespeed Insights

Link Spam Update

In the announcement post of the Link Spam Update, Google shared some general recommendations about links and link building. As these are known best practices, we’ll only list the most important ones:

  • Link building tactics that violate Google’s guidelines on link schemes should be avoided.
  • Any outbound links on your website that you don’t want Google to follow should be properly tagged with the attributes “nofollow”, “ugc” or “sponsored”, depending on the type of link.
  • You should use the “sponsored” attribute for affiliate links and links in sponsored posts.

The post caused some confusion among SEOs as to whether affiliate links and links in sponsored content that are tagged with nofollow should be switched to sponsored.

Both John Muller and Gary Illyes from Google confirmed that this is not necessary and that Google simply appreciates if website owners use sponsored or ugc to share more information about the type of links they use. So, if you’re using nofollow for commercial links as well that’s totally fine and there’s no need to switch for now.

As with the spam updates in June, it’s very unlikely that you’ve been hit by the Link Spam Update as long as you’re not relying on spammy link-building techniques. If you still think that the update impacted your rankings, we recommend you to go through Google’s guidelines linked above and check whether you might have violated them in the past. If yes, you should avoid such tactics in the future.

Core Updates

Let’s get to the tricky part – how to recover from Google’s core updates.

Unfortunately, Google keeps a low profile when it comes to its core updates. Google’s general recommendation is to ask yourself how you can improve the overall quality of your website.

Google shares some tips on that in this blog post. Most of these tips are related to E-A-T (Expertise, Authority, and Trust). You can find our own guide on E-A-T here.

It can also be helpful to take a step back and ask yourself what kind of content you have to create in order to provide real value to your visitors and how to present this content with the best possible user experience in mind. With core web vitals becoming part of Google’s algorithm, it gets even more important to optimize the user experience on your site.

Following these tips always makes sense, regardless of whether you’re faced with a ranking drop due to one of Google’s latest updates or whether you want to prepare yourself for future core updates.

If your rankings improved significantly, that’s great news! Google’s main goal with the core updates is to improve the overall quality of search results, so if you’ve profited from this update, Google apparently considers your site to offer high-quality content.

But you should still keep an eye on your rankings – as we’ve seen in the past weeks, Google is always up for an unexpected algorithm update. Constantly monitoring and optimizing your website is the key to long-term SEO success anyway!

I got hit in early July pretty hard with a fifty percent reduction in search impressions. Thanks for the insight.

    13. September 2021 15:14

    Hopefully you’ll be able to restore your rankings soon, Paul!

Really useful thanks. we’ve seen a 50% drop in traffic from end of June.

We are an ecommerce agency with back links from customers websites. We have thousands of active back links, but a large amount are from very bad (SEO) websites.
Do you think we should just disavow the ones which have a high toxicity score?

    19. August 2021 11:50

    Hi Josh, if the traffic drop started on July 1 it’s more likely that you’ve been hit by the July Core Update. However, it’s hard to give you specific recommendations without knowing your website. We’ll be happy to help if you just drop us an email ([email protected]) and specify which Seobility project you’re referring to 🙂
