There have been so many major Google algorithm updates since 2013. In fact, Google makes 500-600 changes to its search algorithm every year! Google has been working very hard making their search engine results more relevant for the user (you).
In this post, you are going to learn about all of the major Google algorithm changes since 2013 including:
We also have created an all new infographic that we know you're going to love!
While most of the algorithm changes Google does in a given year are minor and some websites may see a little shuffle in rankings, there are some major ones. These kinds of updates come around a few times a year and can have a huge impact on search rankings.
Typically these updates get a lot of buzz on the web once they roll out.
Savvy digital marketers track these updates and use them to explain changes they find in their search rankings. This also helps to give you insight on how to better optimize your website.

Bert
What is it?
First released in February 2011 Panda's mission is to rid the search results of "low-quality" sites.
Why is it important?
The algorithm helps push high-quality sites with lots of original, informative content to the top of the SERPs. This update will affect a whole site and not just one page on a site.
Who does it impact?
If you have a site with pages containing thin or duplicate content you will want to fix that because it can bring your entire site down. Many e-commerce and "how-to" sites were impacted with Panda.
Interesting factoid: the Panda algorithm is named after an engineer at Google who actually has the last name Panda!
First released in May 2012, Knowledge Graph's mission was to deliver the information the user seeks without them having to leave Google.
Why is it important?
This is part of Google's mission to have the search engine answer, converse and anticipate the searcher's intent.
Who does it impact?
If you're an established brand Google will now bring up data about your company automatically into the knowledge box.
What is it?
First released in April 2012, Google Penguin's job was to decrease SERP rankings of websites that use unnatural "black hat" link building practices. As of September 26, 2016, Penguin is now part of Google's core algorithm.
Why is it important?
There are a lot of myths about off-page SEO and many people fall victim to them. In Google's eyes "any link created with the purpose of increasing your rank is considered to be a violation of Google webmaster guidelines." *1
Who does it impact?
Penguin affects approximately 3.1% of search queries in English and an even larger percentage of highly spammed languages. If you have been hit with a Penguin penalty you can use the guidelines on this page to help you recover.
What is it?
Launched in August 2012, Google's Pirate Update was designed to stop sites with many copyright infringement penalties.
Why is it important?
Google was under pressure from media companies to do something about pirating sites.
Who does it impact?
So now sites that are reported through Google’s DMCA system will be reviewed and removed from Google's SERPs. Pirates beware!
Launched in August 2013, Google's In-Depth Articles feature now places rich content related to a person, organization name or other broad topic at the top of search results.
Why is it Important?
Pages with this feature only have nine organic results knocking #10 to page two.
Who does it impact?
If your pages are related to a person, organization name, or other broad topic, you have a very good opportunity here.
What is it?
Launched in August 2013, Google Hummingbird is a whole new algorithm.
Why is it important?
Using a "conversational search" style Google will look at a query like "Best place to buy a classic guitar near my home?" and it will show you local search results for places that sell classic guitars in your location. Before it would only show you results for "buy" "classic guitar".
Who does it impact?
All search results were affected and more local businesses could see traffic increases because of situations like the example above.
What is it?
Launched July of 2013, the Payday Loans update targets spammy queries like payday loans, pornographic terms and other highly spammed keywords.
Why is it important?
This should help lower page rankings on sites that use illegal link building and other black hat techniques.
Who does it impact?
This has affected 2.3% of English queries.
What is it?
Launched July of 2014, Google Pigeon provides more relevant accurate and local results for your query.
Why is it important?
Now if you search "car repair" you won't get a result from San Francisco, California when you're in Moosejaw, Saskatchewan.
Who does it impact?
Local businesses should see a boost in traffic.
What is it?
Launched in July of 2011, Google Authorship was a feature that allowed writers to tag their content and relate it back to a Google+ profile.
Why is it important?
It included the author's profile photo and their name in search results next to the meta description of the result. In July of 2014 Google removed author's photos and then in August 2014 it was removed from search results altogether.
Who does it impact?
This impacted content writers with Google+ profiles.
What is it?
In May of 2013 there was a lot of changes in search engine rankings. Google declined to comment on the changes.
Why is it important?
It was speculated that changes were being pushed to Penguin because a lot of spammy queries were being affected.
Who does it impact?
Pages that contained spammy queries were targeted although this cannot be confirmed.
What is it?
Launched in May of 2013, The Domain Crowding update helps filter multiple results from one domain when you search for something with a site name in the query.
Why is it important?
If you searched "New York attractions" you would be bombarded with results from one domain with high authority. Now you will only get one result from that domain in the first two pages of Google search results.
Who does it impact?
If your domain dominated the search results with multiple ranking pages, you were impacted.
What is it?
In July of 2013, Google announced that in an effort to soften the blows from Panda updates they will be changing how they roll out updates.
Why is it important?
Now Google will be rolling out panda updates every month but spread out over 10 days of the month. If they start on the seventh they will spread the updates out until the 17th.
Who does it impact?
If you have been affected by Panda updated in the past and have not corrected, you will be impacted by these softer updates.
What is it?
In June of 2013, Google said that they had a lot of updates to the PayDay Loans update and that they would be rolling the changes out over 3 weeks.
Why is it important?
If you were affected by the PayDay Loans update this will give you a few more weeks to adjust your web pages.
Who does it impact?
Pages targeting spammy queries would be affected.
What is it?
In July of 2013 Google changed the Panda algorithm to soften the blows it was delivering to web pages around the world.
Why is it important?
Webmasters have noted an increase in traffic to their sites.
Who does it impact?
If you were impacted by Panda in the past you too may have noticed a bump in your traffic.
What is it?
At times Google's SERPs will have a lot of volatility but will not be named or confirmed by Google.
Why is it important?
Google does not comment on the cause of these spikes. But they are usually short-lived and rankings go back to where they were the prior to the spikes.
Who does it impact?
It is typically unclear what types of sites were affected. But everything goes back to normal soon after, so it doesn't really matter.
What is it?
Released January of 2012, Google's "Page Layout" algorithm aimed to make surfing the web a better experience for users.
Why is it important?
Pages with a bunch of ads above the fold are now penalized and will suffer a drop in search result rankings. Pop-ups, Pop-unders and Overlay ads on pages do not make a page get a penalty, only Static ads.
Who does it impact?
If your sites have a large ad block above the fold you will be impacted and should adjust your site accordingly.
Launched August of 2014, Google's "HTTPS/SSL" update will give a minor boost to sites using a SSL 2048-bit key certificate.
Why is it important?
Google has insisted that this will be a very minor ranking signal. If you do decide to use HTTPS/SSL on your site be sure to follow these guidelines from Google.
Who does it impact?
It has an impact on less than 1% of global queries.
Added in October of 2014, the "In The News" box aimed to give the user easy access to relevant news for their search. The box includes videos, blogs, social media posts, press releases and mainstream news.
Why is it important?
This update helps give searchers a better user experience. It will also likely help drive traffic to sites who have content that shows up in the box.
Who does it impact?
If you post a lot of trending news posts on your site you will likely get a surge in traffic.
What is it?
Launched Dec of 2014, Google has announced that they will be changing the way they roll out Penguin updates.
Why is it important?
Many SEOs have been pushing Google to update Penguin faster and it seems that a continual live update is their answer. From now on Google will be updating Penguin in their live algorithm rather than offline and then pushing the changes live. It is unsure how this will affect people that have disavowed links and have done other link removal efforts.
Who does it impact?
If your site has been impacted by Penguin you will likely be impacted by this update.
What is it?
Launched in April of 2015 , Google's Mobile Update AKA "Mobilegeddon" has made mobile friendliness a significant ranking signal in their algorithm.
Why is it important?
Google really wants to make the mobile experience the best it can be and the best way to do that is to make not being mobile friendly a factor in bad SERP ranking.
Who does it impact?
If your site is mobile friendly than you might see a bump in the SERPs. If your site is not, you may notice a decline. Google has offered a mobile usability report here so go and check your site out today.
Launched in May of 2015, Google changed how its algorithm ranks sites with low quality content.
Why is it important?
Sites should have content published by experts or enthusiasts in their field, it should not have duplicate, redundant or overlapping content. Google actually published a post here if you want to read more.
Who does it impact?
It seems that sites with "common knowledge" were affected most by this update.
What is it?
Announced in October 2015, RankBrain is Google's machine-learning artificial intelligence system.
Why is it important?
Not only is it a mouthful, but it will help Google to process search results. In case you're wondering what machine learning is, you can look here. In short, it is where a machine teaches itself how to do something rather than being taught by humans... yes, it sounds like something from a movie but it will really help your search results.
Who will it impact?
This will impact all search results. In fact, Google actually confirmed that RankBrain will be the third most important ranking factor.
What is it?
Launched in Feb 2016, Google has removed the ad sidebar from SERPs and placed four ads at the top of the search results.
Why is it important?
The top block used to only have 1-3 ads but in an effort to provide a better mobile experience they have made this change. We suspect this will drive up Adwords bids as there is now less ad real estate. Good for Google and users, bad for SEMs.
Who does it impact?
Other than searchers, this will impact any SEMs using Ad Words.
What is it?
While this September 2016 update is unconfirmed by Google, the SEO community noted a major shake-up in pack results and organic results.
Why is it important?
This will affect local pack and finder results for businesses. For example, if you are one of six law offices in the same building, it will filter the results and show only a couple of them. Don't worry though, your Google My Business Listing is still there and is visible in finder results when users zoom in on the map.
Another by-product of this update saw a boost in rankings for businesses who have mailing addresses inside city limits but located just outside Google's official city map.
Who does it impact?
Multiple similar businesses sharing the same address and businesses located just outside the Google map of a city, but with mailing addresses within city limits.
What is it?
Launched in January 2017, Google is now penalizing aggressive interstitials and pop-ups that might negatively affect mobile user experience.
Why is it important?
This update caused quite a stir due to the prevalence of pop-up usage on websites. The good news is that as long as you give users the option to exit the pop up, and that it's not covering the main content before you're able to read it, you should be okay.
Who does it impact?
This is wide-reaching penalty, because it targets any page that shows up in search results. Once a user clicks and is sent to the page, any pop-ups or interstitials breaking these new rules could result in a penalty.
What is it?
According to MozCast, they noticed that half of page-1 Google organic results were secure/HTTPs as of mid-April 2017. This number increased to close to 75% by the end of 2017.
Why is it important?
Simply put, if your web pages aren't secure or using HTTPs they're going to be ranked down in the search rankings. You should want this for your website anyways.
Who does it impact?
This observation affects search results, and more importantly the pages who are being ranked for being secure or having HTTPs. Thumbs up for them, and some great motivation for those who haven't made the switch yet.
What is it?
On June 20, 2017, Google officially launched their jobs portal, including a stand-alone 3-pack of job listings in search results. These results drew data from almost all of the major providers including LinkedIn, Monster, Glassdoor, and CareerBuilder.
Why is this important?
This is huge news for employers looking to fill positions. Now, searchers can type in a job they're interested in and find job listings in their area.
Who does it impact?
This is a welcome update for job seekers and employers because the aim is to bring a faster connection between them right through the search engine.
What is it?
On October 17, 2017, Google began warning visitors to sites with unsecured form. While this is not an algorithm update, it's important to note as Google continues their push towards HTTPs.
Why is it important?
This warning and the push to HTTPs may have a material impact on site traffic for those with unsecured forms.
Who does it impact?
Websites that haven't made the switch to HTTPs yet. This is a not-so-gentle reminder to make the move to secure sites if you don't want your traffic to suffer.
What is it?
Between October 27 and 31 in 2017, there was a substantial drop in Featured Snippets. This happened alongside a jump in Knowledge Panels, as Google began adding many panels for broad terms and objects.
Why is it important?
Ranking content to hopefully be used as a featured snippet defining the search took a major hit. Now, Google is wanting to replace them with Knowledge Panels for consistency and unbiased information. Previously, things like common household items had definitions and similar search previews from e-commerce sites.
Who does it impact?
This tweak to the algorithm has future implications for Featured Snippets on SERPs if they continue to drop in favour of Knowledge Panels. If your site is ranking for these snippets, they may not be seen anymore.
What is it?
After testing longer search snippets for over two years, Google rolled out this update at the end of November 2017. The new Meta Description limit almost doubled, from the previous 155 characters up to 300 characters.
Why is this important?
This algorithm change gives more room to describe a page and optimize for search results. Woot! You can also write more of what you want to say without shorting sentences all the time. Double woot!
Who does it impact?
This affects all crawled pages with meta descriptions and will shake up the SERPs. If you have a website, take note of the new limit and start implementing it today on all of your pages.
What is it?
On March 12, Google confirmed via Twitter that a “broad core algorithm update” had rolled out the prior week. While Google was light on details, Google said the changes were meant to “benefit pages that were previously under-rewarded,” and advised everyone to “continue building great content.”
Why is it important?
Google’s algorithm updates are focused on relevance. If rankings were affected by last month’s update, it’s not an indication that a site’s content is of low quality.
Who does it impact?
When it comes to figuring out how to make a site more relevant, Google suggests getting feedback from users about what you could be doing differently to improve the site overall.
What is it?
Google confirmed via Twitter the release of another broad core algorithm update, and indicated it was similar to the March 9, 2018 update, which was about content relevance.
Why is it important?
It was explained that a “broad core” algorithm update is something that occurs routinely several times per year.
Who does it impact?
If your rankings are affected by this update, it’s not necessarily an indication that the quality of your content needs to be improved. Rather, it’s more of a sign that your content needs to be more relevant to the audience who is searching for it.
What is it?
Google confirmed via Twitter for the third time this year the rollout of a broad core algorithm update. In doing so, Google’s Search Liaison Danny Sullivan recommended following the guidance it provided following the March 9, 2018 update.
Why is it important?
This update has been referred to as “Medic” by some in the industry, even though Google said it was a general ranking update and wasn’t specifically targeting medical sites. The change was to improve how Google matches relevant results to search queries.
Who does it impact?
"Want to do better with a broad change? Have great content. Yeah, the same boring answer. But if you want a better idea of what we consider great content, read our raters guidelines. That’s like almost 200 pages of things to consider: https://t.co/pO3AHxFVrV"
— Danny Sullivan (@dannysullivan) August 1, 2018
What is it?
On September 27 (Google’s 20th birthday), many within the SEO community began noticing significant spikes and drops in traffic, indicating some sort of update was underway. Some of the sites impacted by the August broad core algorithm update reportedly made a recovery.
Why is it important?
When it comes to these core algorithm updates, it’s not a matter of fixing specific issues. Google is more concerned with how relevant content is to searchers’ queries.
Who does it impact?
The most important thing site owners can do is to improve the relevance of their content. So consider how to make that content more relevant to the queries it previously ranked well for.
What is it?
Some webmasters reported changes starting around Halloween, perhaps indicating an (unconfirmed) Google update. But there was little evidence of a significant update here. The more likely cause of the chatter was spillover from the August broad core algorithm update and Google ramping up its use of neural matching.
Why is it important?
The SEO industry has long discussed so-called Phantom updates that Google has consistently denied. We now know that Google was telling the truth. Google performs changes to the algorithm almost every day of the week.
Who does it impact?
Based on the low level of discussion and no confirmation from Google, it’s very likely there wasn’t a core algorithm update.
What is it?
Throughout the past year Google has been rolling out changes designed to improve Google’s ability to understand a search query and the content on a web page. These kinds of algorithms are focused on identifying the best pages to solve a user’s problem.
Why is it important?
The focus may be on relevance, not quality. Google is making updates designed to return relevant search results that please Google’s users.
Who does it impact?
The WebmasterWorld discussions are all over the place. One member reported success updating their page titles then followed up days later to report the changes reverted. Changing things on a web page during a Google Update can lead to unreliable conclusions. It’s important to understand that an update can last several weeks as it presumably rolls out throughout the data centres. Should your pages lose rankings, you may wish to wait ten to fifteen days before making any changes.
What is it?
Broad core updates are improvements to Google’s overall algorithm for the purpose of better understanding search queries and webpages.
Why is it important?
These improvements help Google to more accurately match search queries to webpages and improve user satisfaction.
Who does it impact?
This update will affect how a page is ranked. However, Google has said that in broad core updates, there is nothing to fix.
What is it?
On June 2, Google Search Liaison Danny Sullivan tweeted that Google would be releasing a new broad core algorithm update on June 3. The next day, Google confirmed the update was live and would be rolling out to its various data centres over the coming days. As is the case with any broad core algorithm update, Google tells us there is nothing specific to fix because a core update encompasses a broad range of factors.
Why is it important?
Over the past few years Google introduced Neural Matching and Rank Brain to help Google better understand search queries (neural matching) and to help Google understand web pages better by matching pages to concepts (rank brain). Google is getting better at understanding what users want and are satisfied with when they make these kinds of queries.
Who does it impact?
What is known is that Google has not been targeting health sites. So this means that the changes may affect a broad range of sites, not just health related sites. It may be useful to investigate why some health sites are losing traffic because that may give clues as to what is affecting some non-health websites.
What is it?
A broad core update is an algorithm update that can impact the search visibility of a large number of websites. Each time an update is rolled out, Google reconsiders that SERP (Search Engine Results Pages) Ranking of websites based on expertise, authoritativeness, trustworthiness (E-A-T)
Google typically pushes broad core ranking updates only a few times per year, and on September 24, 2019, they pushed yet another. Google’s Danny Sullivan pre-announced the update on Twitter and explained like previous core updates, it would be a global update and could take several days to fully roll out.
Why is it important?
A broad core algorithm update focuses on a wide range of changes. In general the updates work together to improve relevance.
Who does it impact?
While there were some reports of traffic collapse, the overall narrative in many online discussions were a mix of recoveries and mild wins and losses on the order of 10 to 20 percent, nothing catastrophic as in past updates. What stood out among the publishers who reported losses is how many attributed it to links. Although there were many discussing links, links are likely one part of many changes that came with this update.
What is it?
It is Google’s neural network-based technique for natural language processing (NLP) pre-training. BERT stands for Bidirectional Encoder Representations from Transformers.
Why is it important?
In short, BERT can help computers understand language a bit more like humans do.
Who does it impact?
Bert will impact 1 in 10 queries in terms of changing the results that rank for those queries. It helps better understand the nuances and context of words in searches and better match those queries with more relevant results. It is also used for featured snippets.
In one example, Google said, with a search for “2019 brazil traveler to usa need a visa,” the word “to” and its relationship to the other words in query are important for understanding the meaning. Previously, Google wouldn’t understand the importance of this connection and would return results about U.S. citizens traveling to Brazil. “With BERT, Search is able to grasp this nuance and know that the very common word “to” actually matters a lot here, and we can provide a much more relevant result for this query,” Google explained.
There you have it. The major Google algorithm updates since 2013. As you can see, Google is always hard at work making their search engine better for its user.
As always you want to create high-quality, original content that your readers will value, like, and share. If you do that and follow the information in these updates you should have a good chance at getting a nice ranking for your pages.
