Google Algorithm History

Since its first update in 2003, Google has become the most widely used search engine globally and has never looked back. The company came into existence in 1998 with a vision to collect information and have people access them whenever they want to.

Google updates its algorithms multiple times a year. Though most of them are minor updates and do not impact SEO basics as much, significant changes regarding SERP and how content gets ranked are brought almost every year.

Google updates its algorithms to understand the search intent of the user better and provide localized results. Through these updates in its complex set of computer programs, it ranks content on websites as per their relevance for the information that the user seeks.

Why does Google update its algorithms regularly?

Google has the vision to collate all relevant information about a particular topic and present users with the best possible answers to their queries. As the search engine kept updating its codes, the relevance, and quality of search results improved through the years.

From penalizing keyword stuffing and powering local SEO to optimizing voice search, each essential update made by Google has refined the answer that users get when they enter any query or look for information online.

This blog piece will focus on the most important updates that Google has rolled out in these past two decades.

History of Google Algorithm Updates

Google’s changes to its algorithms that significantly impact website rankings are called Core updates. These updates impact website rankings across diverse platforms and industries.

So let’s take a look into the most essential Google core updates so far:

Florida Update (2003)

The very first update made by Google was the Florida update in 2003. These updates caused a radical change in the way search results are displayed.

At the time, keyword stuffing and spamming were prevalent among websites with a huge search volume. Repetition of keywords in a page(including keywords that were in-text colored like the background) was a common practice among websites, particularly those of retail businesses like hotels and jewelry brands.

The Florida updates saw a significant shift towards using white hat techniques in SEO by penalizing sites with invisible text, hidden links, and keyword stuffing.

Big Daddy Update (2006)

The Big Daddy update came in 2006, which essentially tackled spammy backlinks. Google rewarded websites with high-quality backlinks and penalized websites that used unnatural incoming and outbound links to improve their search results.

It penalized sites that bought links, used reciprocal links, or practiced any spammy backlinking tactics.

Vince Update (2009)

The Vince updates favored popular brands which had an established offline presence. Named after an engineer from Google, the Vince updates started considering trust in search rankings by supporting leaders in their respective industries.

These updates were made because Google realized that users were more likely to trust brands they are familiar with over others which just popped up as search results online. With these updates, websites started ranking even for keywords with a high search volume and competition, like laptops, mobile phones, etc.

Caffeine Update (2010)

Caffeine update was the first update released by the search engine in 2010. This update changed the way Google indexed sites, taking into account the information provided by the web page.

This update was all about testing the recency and speed of web pages. Websites that provided comprehensive information to users were rewarded with the Caffeine update. Relevant and fresh content was given preference by Google.

May Day Update (2010)

In May of 2010, Google announced its latest update just before May Day, which was named as such.

These updates affected long-tail keywords to refine the quality of Google search results.

Long-tail keywords are the ones that include 3-5 words. These keywords are more specific and allow you to target a niche demographic, which allows you to target high-quality traffic.

Long-tail keywords still play an important role in your SEO effort. But the May Day update also favored original and relevant content that used long-tail keywords. Websites that used plagiarized or duplicate content saw themselves drop in search rankings, irrespective of their business size.

Panda update (2011)

The Panda updates are among the most popular changes made by Google to its algorithms.

The Panda updates focus on on-page SEO factors. These updates made SEO a field that required constant deliberations; it emphasized on websites that provided genuine value to users over sites that were just created to rank.

Websites that existed just as affiliates or with very thin content were negatively affected by these updates.

The Panda changes were included in Google’s core algorithms five years later. This saw a paradigm shift in SEO methodology with a renewed focus on reducing bounce rate and content repetition throughout the website.

Penguin & Venice updates (2012)

The Venice updates were rolled out first, which was the first time that Google understood the need for localized results for users. With this update, searchers could get localized results around them based on their IP address or the location that they searched.

The Penguin updates in the same year were more significant in terms of tackling the ethical issue involved in SEO. The Penguin update sought to penalize sites that had low-quality backlinks that were either irrelevant or paid.

Black-Hat techniques like purchased links or low-quality links were no longer considered by the search engine with more emphasis on organic link building.

Websites that ranked higher with artificial links found themselves dropping significantly in search rankings with the Penguin updates.

Hummingbird update (2013)

Another change by Google, which forever altered the way we search information online, the Hummingbird updates formed the basis for voice-searching, which is still a developing SEO prospect.

The Hummingbird updates focussed on each word of a search query made by the user to better understand their intent.

This alteration in its algorithm called for better quality content with an organic use of keywords, thereby preventing the over-optimization of a few words. SEO professionals were expected to optimize their content and site to match the user intent of their query, rather than just focussing on a few words.

Pigeon and HTTP update (2014)

The Pigeon updates also refined localized results by optimizing the results page, and Google maps simultaneously. The update focussed on local results in making them more accurate and considered quality ranking factors for websites.

The HTTP update, launched in the same year, saw Google considering site security an important factor in rankings. This update boosted websites that implemented the right HTTP and user security.

Mobilegeddon update (2015)

By 2015, search trends worldwide saw a surge in mobile devices to search information online. This led to the name of this update as Mobilegeddon.

Although the influence of this update came into effect long after, this made the SEO and web development industry shift their focus on making mobile-friendly web designs. Mobile responsive sites were awarded by Google in search indexing.

RankBrain update (2015)

In 2015, Google released another update to its algorithms by updating the Hummingbird. This update enhanced the search engine’s ability to understand user intent by analyzing the user’s search history and returning the best result possible.

The RankBrain update saw Google adopt Machine Learning in their algorithm to understand the context of the user’s query. This tweaked Google’s response to search intent by analyzing the search history and language.

This update made experts of SEO use online tools to identify which words are used in pages that rank for the intended keyword and how many times they were used.

Medic update (2018)

The medic update brought sweeping changes to ranking factors, particularly the websites that pertained to the medical and healthcare industry.

The medic update sought for the user’s well-being and protected them from unsubstantiated claims made by medical and healthcare websites.

For the first time, it made SEO experts focus on E-A-T signals, or Expertise, Authority, and Trust signals from websites that offered monetary or medical information. These updates affected monetary and health retail sites that had no expertise or affiliation with regulatory authorities.

BERT updates (2019)

In 2019, Google announced the BERT updates and claimed it as the most important change in the preceding five years.

The name is an acronym for Bidirectional Encoder Representations from Transformers, which is a neural-based machine learning algorithm for processing natural language.

BERT analyzes the context of a keyword by understanding the words that come before or after them. It takes the relation of all words used in a search phrase, which boosts the search engine’s understanding of search intent.

Page Experience update (2021)

Eighteen years after Google made its first significant algorithm change, the page experience update came into effect, which measured metrics that influence user experiences like load speed, site performance, and interaction.

The update merged the current page experience signals with Core web vitals, which included a real-life measurement of user experience.

Google also added Core Web vitals and Page Experience to its search console to enable SEO experts to identify user experience factors in search rankings and implement changes towards the same.

Expect more updates from Google

Experienced SEO professionals today keep a keen eye out for the next update that Google may implement in its algorithm.

The next update is Multitask United Model or MUM updates to see a complete overhaul of Google searches. These updates will enable Google to multi-task simultaneously to understand and deliver results to complex users’ queries. With this change, the search engine’s algorithm can read, understand and learn in multiple languages and respond to audio and video as well.

However, no announcement has been made for the release date of the MUM update.

Evidently, Google has become more powerful in the past 20 years as a search engine in delivering quality results to online searches. With a large focus on user intent and experience, Google is expected to continue updating its algorithms regularly to keep up with the dynamic nature of modern technology in offering convenience to humans.
