While temperatures start to rise with the start of the summer, the SEO community has started to feel the new “heatwave” coming from Google.

June kicked off as a fluctuate month with the new Google Core Update and continued with the Page Experience (initially scheduled to release in May). Following this, two spam updates hit the digital landscape by the end of the month. But that is not all.

While SEO professionals worldwide are still trying to understand the changes that the updates have caused to their sites, July is expected to be another powerful month.

To help you understand this and what is yet to happen, we have put together this roundup article. Stay tuned, and welcome to the summer of the updates!

The Google June 2021 Core Update finished rolling out as of 12th of June, which “showed a nice amount of Google fluctuation on June 11th and 12th “in words of Barry Schwartz, Search Engine Land’s editor. Up and downs was the general rule for all tracking tools, leaving the SEO community wanting to know more and just waiting to see the final resolution of the second part of this Core update in July.

Yes, RankRanger felt that this update was much larger than the December 2020 update, which happened to be one of the largest core updates we’ve seen from Google yet. RankRanger said it was higher volatility “particularly in the top five positions.

13th June: John Mueller answers ‘what to do about link building’

Google’s top advocate John Mueller gave us some tips about link building best practices in an Office Hours hangout. One of the questions that all SEOs have in mind was formulated: is it necessary to spend thousands of dollars for links? Mueller referred to how Google treats artificial links:

What should you do now…

I think that’s a super complicated question because there’s no one answer for everyone. So I think first of all, like you probably recognised, artificially building links, dropping links on other sites, buying links all of that is against the webmaster guidelines. And we take action on that algorithmically, we take action on that manually. And the actions that we take include demoting the site that is buying the links, demoting the site that is selling the links. Sometimes we also take more subtle action in that we just ignore all of those links.

On the other hand, when asked about paid links Mueller said:

For example, if we recognise that a site is regularly selling links but they also have other things around that, then we go in and say okay, we will ignore all links on this website. That basically means…a lot of these sites are things were people still sell links because it is like they can sell it and they find a seller then of course they will try to do that. But those links have absolutely no effect. So that seems like a big waste of time from my point of view.

15th June: The Google Page Experience Update began to roll out

The Google Page Experience Update finally started to roll out last month, as it was supposed to roll out in May but it was delayed until June.

Moreover, the changes on the rankings caused by Google’s Page Experience Update began to roll out slowly and progressively, and it won’t be completed until the end of August. Therefore, sites are not expected to see big changes following this update,   

As stated by Google: 

We will begin using page experience as part of our ranking systems beginning in mid-June 2021. However, page experience won’t play its full role as part of those systems until the end of August. You can think it as if you are adding a flavouring to a food you’re preparing. Rather than add the flavour all at once into the mix, we’ll be slowly adding it all over this time period.

Then, why is this update so important? Let’s make a quick recap on Page Experience.

In plain words, Page Experience is an algorithm that measures the overall experiences of a user on a website and search results and then, the algo will sense if there’s something that needs improvement, to offer a better experience. Moreover, the most important page experience signals are mobile-friendliness, safe browsing (HTTPS/HTTP), and invasive interstitials.

Furthermore, Core Web Vitals are composed of various signals related to loading experience:

  1. Largest Contentful Paint. LCP measures the total time that it takes for the main content on a website to load. It focuses on what a user sees on the screen. A good LCP score will be 2.5 seconds, while from 4.0 it is considered to be too poor.

  1. First Input Delay. FID is in charge of measuring the impression of a page when the user first interacts with a page. Responsiveness and interactivity are the top factors here, and what it measures is the time it takes to a user from when it clicks the link to the time the browser responds to it.

  • Cumulative Layout Shift. Finally, CLS analyses visual stability and measures non expected layout shifts. From 0.1 seconds being a good score, to 0.25 being identified as a poor score.

17th June: Changes coming to AMP and top stories

From now on, AMP won’t be necessary for inclusion in Top Stories. Moreover, this means that until now, only websites build with AMP HTML were considered for this section. Google will, from now on, previously ineligible content will be eligible. Therefore, if you want your site to appear in Top Stories, you will need to:

  • Publish relevant content
  • Keep a good score of Core Web Vitals and Page Experience
  • Always follow Google’s guidelines.

24th June: Google News SEO: The definitive resources list

A new list of the official documentation, guides and tips was released by the one and only Barry Adams on SEO for Google News.

25th June: Google delays plans to block cookies until 2023 and pauses FLoC

Google announced last month that they will delay their plans to block third party cookies to late 2023 and will also pause testing of FLoC, its cookie less alternative.

We plan to conclude this origin trial in the coming weeks and incorporate input, before advancing to further ecosystem testing.

Google divided the process into two stages, the first one starting in late 2022, and stage 2 starting by mid-2023.

26th June: How HTTP status codes, network and DNS errors affect Google Search

28th June: Part two of Google Search spam update is released

This second Google Search spam update was released by the end of the month, five days after the first one was released. Both parts were one-day updates and were “global” and targeted web and image results. 

Moreover, the main target of this update was spam generated by hacked websites, and it was drove by Artificial Intelligence. In their own words: 

By combining our deep knowledge of spam with AI, last year we were able to build our very own spam-fighting AI that is incredibly effective at catching both known and new spam trends.

For example, we have reduced sites with auto-generated and scraped content by more than 80% compared to a couple of years ago.

The kind of spam that Google does not look at with good eyes is, between others:

  • Auto generated content 
  • Link schemes
  • Unoriginal content
  • Cloaking
  • Hidden text or links
  • Doorway pages
  • Scraped content 
  • Abusing structured data

29th June: How MUM improved Google Searches for vaccine information

With a new technology called Multitask Unified Model (MUM), Google uses Artificial Intelligence to provide online users with a new experience when performing searches.

As coronavirus keeps occupying an important place within our lives, the internet giant has focused its efforts on offering the most accurate and trustworthy information about the COVID-19 vaccine. Furthermore, Google wanted to identify the different ways that people use to refer to vaccines all around the world. MUM is the tool that is behind this whole process. Thus, MUM has been able to identify over 800 variations of vaccine names in more than 50 languages in just seconds.

This way, MUM has helped users worldwide to get critical data promptly, opening the door for future systems and search improvements.

To wrap it up

June Core Update starts rolling out, the Spam update hits the ground two times, Core Web Vitals are a ranking factor from now on, etc. A lot has been going on in the SEO landscape during June. Keep an eye on your metrics, as July is going to be a very exciting month.
