The search engine utilizes a variety of algorithms and multiple scale aspects to deliver web pages ranked by relevancy on its search engine results pages.

The Complete List of Google Algorithm Updates in 2021

As we have seen a vast number of updates in the year 2021 some of the updates from Google have rocked the  SEO boat like June, July, and November core updates. Let’s start from the year starting and look at some of the major updates by Google.

 Passage Ranking Update

On February 10, Google announced one of the major updates that have affected worldwide searches up to 7%. In this update, Google has announced that Google will consider passages and content from the entire web page for specific search query results also and can rank the entire web page as per that. This was first applied to English Language queries and the United States. 

About This Result Update

Another update from Google that was provided by Google in February is Google adds context to each search result so that searchers may decide which results will be most useful to them. This is available for the beta version called About this Result Update.

Check the list of information displayed in Google about this result update:

  • Date of the page when first indexed by Google
  • Connection to site is secure or not
  • Gives Backlinks details for the particular page
  • The language of the page
  • Content featured that relates to your search query

Featured Snippet Drop

MozCast observed a 40% drop in exposure for Featured Snippets, which had fallen to their lowest position since 2015 on February 19. In many cases, Featured Snippets were completely removed, which had a particularly negative impact on health and money searches. On further inspection, these were heavily concentrated on small queries, mainly one-term queries, and disproportionately hit YMYL queries.

Featured Snippet Recovery

After three weeks of featured snippets dropping up to 40%, they abruptly vanished from Google Search, only to magically reappear on March 12 with the same ranking positions as previously. For this change, Google has not explained the absence or return of Featured Snippets, nor has it acknowledged whether the incident was caused by a faulty algorithm update, a bug, or something else. That’s a usual diplomatic answer from John Mueller, but the Featured Snippet disappearance technique was far from “natural organic changes.”

Rolling Out Mobile-First Indexing

With the rise of mobile usage, Google began putting more priority on mobile-friendliness as a ranking factor in 2015. In 2016 Google has officially announced that they will start ranking pages based on mobile app friendliness. The Mobile-First Indexing updates were launched in 2016 end of the year. On March 26 Google announced that after experimenting all these years they have started migrating sites that follow best practices for the mobile-first updates. As of July 2021, it will be compulsory for all old and new sites.

Product Reviews Update 

The purpose of Google’s April 2021 product reviews update was to stimulate product evaluations that included in-depth research, intelligent analysis, and unique content rather than just summarizing a list of items.

As per the update from Google, your product reviews should have below listed points must be taken into consideration:

  • Share expert knowledge for the product
  • Deliver review content that is distinct from that provided by manufacturers.
  • Provide measurable performance metrics.
  • Cover comparable items to explain which products are ideal for specific needs or situations?
  • Assist customers in making sapient purchase decisions.

MUM Update

MUM was introduced on May.2021 by Google’s Prabhakar Raghvan. The Multitask Unified Model (MUM) is a natural terminology model that is far more effective than the BERT of October 2019. MUM recognizes information in text and photos, and Google intends to enhance its ability to encompass video and audio as well.

Broad Core Algorithm Update

On 2nd June Google announce the June Core update which is also known as Broad Core Algorithm Update. Google took the unexpected step of revealing not one, but two key algorithm upgrades – one later that day and another later that month.

Page Experience Update

In addition to indexing mobile versions of web pages, Google had included a new set of barometers known as Core Web Vitals as a portion of the page experience upgrade. These are not new standards, but rather newly prioritized criteria for calculating a user’s experience with a website. This will include Largest Contentful Paint, First Input Delay, Cumulative Layout Shift.

July Core Update

Google didn’t waste any time with the July 2021 Core Update, releasing it on the first of the month. The consequence of the June 2021 Core Update had a lesser all-around effect, but it hit tougher and quicker than the first update’s steady rollout, peaking on 1 July and displaying dramatic oscillations after the days that followed.

Link Spam Update

On July 26, Google launched a link spam update that will be rolled out over the next two weeks but took a full month to complete. Google has cautioned that any site that engages in link spam practices may see ranking fluctuations, with sponsored, guest, and affiliate content being the most likely to be affected.

Page Title Rewrites

Google turned out to be adjusting page titles in the SERP based on the search query for a decade. Nevertheless, on August 16, individuals began to witness that Google was substantially modifying their page names, frequently in a negative way. A week later, Google announced that it has developed a new method that will no longer alter titles based on searches but will instead adjust titles to better represent the page as a whole.

Google Spam Update

According to a tweet from Google Search Liaison, a spam upgrade was sent out between November 3 and 11, 2021 as part of their ongoing efforts to enhance search results. In their announcement, they advised that webmasters continue to follow the Webmaster Guidelines.
