Google Algorithm Updates: Arguably the most popular search engine in the world, Google uses various algorithms that rank each webpage. These are based on a variety of factors which can impact how high a website ranks. Algorithm updates are crucial for ensuring that the primary way that Google finds, ranks, and returns search results for queries best serves customers using their SERPs. 

Some algorithm updates are major, and some are minor. Sometimes, we are made aware of them and other times, they are a total surprise. At times, these updates will boost website rankings and, in other cases, penalise them. We have collated an updated list of all the current and past Google Algorithm updates so you can see the patterns in Google’s development. 

Google dominates the search engine market, processing over 3.5 billion daily searches. With over 90% market share in most countries, rankings in Google can make or break website traffic and revenues. This is why Google’s algorithm updates, which impact search results and rankings, are critical for webmasters and digital marketers to understand. Staying on top of Google’s updates and optimizing websites accordingly can provide a significant competitive advantage.

Preparing for and Responding to Google Algorithm Updates: A 360° Approach

Navigating Google’s ever-evolving algorithm can feel like riding a rollercoaster, but fear not! With a proactive approach, you can not only survive updates but thrive in the face of change. Here’s a detailed guide to prepare and respond effectively:

Google Algorithm Updates 2021

Unconfirmed Algorithm Update – 22 May 2021

In May 2021, a major algorithm change was reported, although it is unconfirmed by Google. This seems to have impacted several industries, primarily in the US, but not exclusively. This was most likely due to changes in the indexing algorithm, as many affected sites saw significant drops in traffic.

Passage Indexing/Ranking – 10 February 2021

On 10 February 2021, Danny Sullivan, Google’s Public Liaison, announced via Twitter that Passage Indexing was to be rolled out today. Made for English language queries in the United States, Google has initially estimated that this update will impact around 7% of all queries on the search engine.

Google Algorithm Updates 2020

Core Update – 3 December 2020

Announced in December, Google appeared to release most of its Core Update on the 3rd of December 2020. This is the third core algorithm update of 2020. Moz found that some sites reported reversals a few days later, but this impact appears limited to those sites. 

Indexing Bug, Part Two – 12 October 2020

By 14 October, Google had claimed that the bulk of the indexing and canonicalisation bus had been fixed.

Indexing Bug, Part One – 29 September 2020

Google had already confirmed in early September that they would roll out an indexing and canonicalisation bug. This seems to have come ahead on September 29th and 30th with full implementation. 

Google Glitch – 10 August 2020

On 10 August, there were massive ranking changes due to SEO, which seemed to disappear. Later, Google confirmed that there was a glitch in their indexing systems. 

Core Update – 4 May 2020

Causing a heavy rankings flux, Google’s Core Update on 4 May saw this occur between then and May 6. Google Search Liaison Danny Sullivan announced this on Twitter. 

In a major announcement that Google’s Danny Sullivan tweeted, it was announced that the URLs placed within featured snippets would no longer appear as traditional organic results. 

This was a massive theory change as Google had always promoted the Featured Snippet as an organic result. Naturally, this impacted CTR as well, having implications for rank tracking. 

Core Update – 13 January 2020

The first core update of 2020 was announced by Google’s Danny Sullivan on Twitter. Google provided similar guidance to that that was set out for previous broad core updates for the algorithm.

Google Algorithm Updates 2019 

BERT (Worldwide) – 9 December 2019

It was confirmed by Google that BERT was beginning a worldwide rollout; this natural language processing algorithm was going to be available in 70 different languages. Some of the languages included were as follows: 

Afrikaans, Albanian, Amharic, Arabic, Armenian, Azeri, Basque, Belarusian, Bulgarian, Catalan, Chinese (Simplified & Taiwan), Croatian, Czech, Danish, Dutch, English, Estonian, Farsi, Finnish, French, Galician, Georgian, German, Greek, Gujarati, Hebrew, Hindi, Hungarian, Icelandic, Indonesian, Italian, Japanese, Javanese, Kannada, Kazakh, Khmer, Korean, Kurdish, Kyrgyz, Lao, Latvian, Lithuanian, Macedonian Malay (Brunei Darussalam & Malaysia), Malayalam, Maltese, Marathi, Mongolian, Nepali, Norwegian, Polish, Portuguese, Punjabi, Romanian, Russian, Serbian, Sinhalese, Slovak, Slovenian, Spanish, Swahili, Swedish, Tagalog, Tajik, Tamil, Telugu, Thai, Turkish, Ukrainian, Urdu, Uzbek, and Vietnamese.

BERT Update – 22 October 2019

The Bert Update was considered one of the biggest upgrades for the algorithm and it was called the biggest update to Google Search in over 5 years. BERT is a natural language processing mode model or NLP. It is designed to help Google interpret natural language searches better, providing better answers to queries after fully understanding the context. 

Google claimed this update would impact featured snippets as well as search rankings. They also estimated it would be used for around 10% of U.S. English searches. 

Broad Core Algorithm Update – 24 September 2019

A broad core update was announced by Google on 24 September that would take a few days to roll out fully. It seemed only to impact sites affected by previous broad core updates. Google’s guidance was similar to previous rollouts. 

Site Diversity Update  – 6 June 2019

This was pre-announced by Google to try and help situations where a site may have had more than two organic listings. While marginally improving SERPS with 3-5 duplicate sites, it didn’t have an overly large impact.

Core Update – 3 June 2019

While Google did announce this on 2 June for a rollout on the 3rd, there were limited details. As with most broad core updates, Google didn’t say anything specific about what it was fixing, more the broad range of factors it was going through to ensure the algorithm was functioning properly. 

However, sites that have been impacted previously were also hit by this update, with some UK publishers receiving heavy losses. 

Indexing Bugs – 23 May 2019

Announcing indexing bugs that would occur two days in a row, Google reported the first bug was preventing new content from being properly indexed. 

Deindexing Bug  – 5 April 2019

Google announced that a bug dropped pages from the search index, meaning that around 4% of stable URLs fell off page one. This was rectified, and sites recovered not too long after that. 

Core Update (a.k.a. Florida 2) – 12 March 2019

The third major core update since using the label, was considered one of the biggest Google core updates in years. 

Valentine’s Day Update – 13 February 2019

There was some indication that an unconfirmed update occurred before or on this date. Reported positive changes from industry and algorithm trackers. 

Google Algorithm Updates 2018 

Unconfirmed Halloween Update – 31 October 2018

Another unconfirmed update, but some webmasters reported changes around Halloween. There is little evidence of a significant change here. Still, there was an argument that there was spillover from the August broad core algorithm update with Google increasing its use of neural matching, which would explain movements. 

A “Small” Update – 27 September 2018

The SEO community noticed significant spikes and drops in traffic on September 27th, 2018. Some sites hit by the August broad core algorithm update had made recoveries, though. Danny Sullivan, Google’s Search Liaison, confirmed that there had been a small update.

‘Medic’ Broad Core Algorithm Update – 1 August 2018

Rolled over a week but peaking on August 1st and 2nd, Google rolled out its broad core Medic algorithm update, which saw widespread reports of massive impact. Interestingly, this update disproportionately affected sites in the health and wellness sector, which Google denied. They said that they were specifically targeting medical sites, and it was a general ranking update. 

Broad Core Algorithm Update – 16 April 2018

While it wasn’t announced, Google confirmed the release of another broad core algorithm update and indicated it was similar to March’s core update, impacting content. 

‘Brackets’ Broad Core Algorithm Update – 9 March 2018

Google confirmed on 12 March that it had rolled out a broad core algorithm update the previous week. It is unclear whether it was multiple updates or one prolonged rolling update. 

The name ‘Brackets’ was coined by Glenn Gabe, but no details other than it was meant to help pages that were previously under-rewarded were mentioned.

Google Algorithm Updates 2017

Maccabees Update – 12 December, 2017

A rare update around the holiday period, which Google usually avoids due to the effect on eCommerce sites, Barry Schwartz named this the “Maccabees” update. Google would only confirm that several small updates had occurred, probably playing it down due to the period it was done. 

Snippet Length Increase – 30 November 2017

Google had been testing longer search snippets for over two years, and on 30 November, it rolled them out across many results. A new Meta Description limit was created from 155 characters to 300 characters. 

Chrome Security Warnings (Forms)  – 17 October 2017

Google launched Chrome 62, which helped to warn visitors of sites with unsecured forms. This might not be an algorithm update, but it was an integral part of Google’s push towards HTTPS and may have a material impact on site traffic. 

Quality Update – 19 August 2017

It was picked up by SEO ranking tools that between August 19th and 20th, there was possibly another Google quality update. Things that were affected were category pages, thin content, and other negative user experience elements including pages with aggressive advertising. 

25 June Update – 25 June 2017

Another unconfirmed update but noticeable through SEO tracking tools, Google updated on this date. Some analysts found that this update caused the biggest fluctuations for pages ranking in positions 6 to 10. It seemed to impact hospitality the most, but other niches were hit. 

Quality Update – 17 May 2017

After SEO tracking tools noticed lots of SERP volatility, it was realised that there was a quality update underway. This appears to have targeted sites with UX issues, thin quality content, and those sites that had aggressive or deceptive advertising content within them. 

Fred – 7 March 2017

Fred was named by Google’s Gary Illyes and appeared to have a major impact on mainly low-value content. It was a confirmed update on 24 March. Still, Google has refused to share specifics of the update, saying that if anyone has questions about it, they can find answers within their Webmaster Quality Guidelines.

6 February Update – 6 February 2017

This was an unconfirmed update, which resulted in a massive rankings shift in Google SERPs. This saw major increases and decreases for a variety of websites. It did result well for those sites with higher-quality and relevant content as they were offered the most visibility,

Intrusive Interstitial Penalty Update – 10 January 2017

This update was released after Google warned in August 2016 that it would target and punish aggressive interstitials and pop-ups that might damage the mobile user experience.

A rare warning before the actual update, there was surprisingly minimal impact reported on sites that should have been affected, according to SEO specialists. 

Google Algorithm Updates 2016

Unnamed Update – 10 November 2016

While unconfirmed, there was data from SEO tracking tools to support the idea of an unconfirmed Google update, which appeared on 10 November. 

Penguin Update 4.0 & Core Algorithm Integration – 23 September 2016

This was the final update for the Penguin Algorithm, which was meant to be gentler when integrated into Google’s core algorithm. This means that it was able to evaluate websites in real-time. 

Instead of entirely penalising sites, this update was designed to devalue bad links, ensuring that pages weren’t downgraded with the rankings.

Quality Update – 1 June 2016

This is another unconfirmed update, but it is clear from the data that this was a quality update surrounded around content. After this update, there was additional search ranking volatility after it.

Mobile-Friendly Update (#2) – 12 May 2016

An update for Google’s first mobile-friendly update meant to increase the effect of the ranking signal. It is also known as Mobilegeddon 2. 

Panda Core Algorithm Incorporation – January 11, 2016

This update saw Panda being incorporated into the core Google Algorithm. This means that Panda was no longer a filter applied to the Google Algorithm but was to be incorporated as one of its core ranking signals. 

Google Algorithm Updates 2015

RankBrain – October 26, 2015

While Google has had RankBrain in testing since April 2015, it officially introduced it on October 26th. RankBrain was designed as a machine learning algorithm. It was meant to filter search results to give users the best answer to their queries. 

When first rolled out, RankBrain accounted for around 15% of all queries, mostly for questions that Google hadn’t encountered before. Now, it is involved in nearly every query that Google receives. It is considered the third most important ranking signal by SEO specialists. 

Panda Update 4.2 (#28) – July 17, 2015

A Panda refresh was announced by Google that could potentially take months to roll out. The immediate impact was unclear, but it was meant to affect 2 to 3 per cent of English queries. Google did not reveal any specifics around the update. 

Phantom Quality Update – May 3, 2015

Due to large-scale ranking changes, this quality update known as Phantom was confirmed to change the core ranking algorithm. This update was designed to specifically target quality signals. It appears that sites that had too many ads or content quality issues were going to be impacted by these changes. 

Mobile-Friendly Update – April 21, 2015

Known as ‘Mobilegeddon’, this mobile-friendly update was meant to reward those websites that were mobile-friendly with better search rankings and provide better results to searchers on mobile devices. This update was for all languages.
