The Evolution of Google Algorithm Changes

Google, the unchallenged search engine titan, has been putting up endless effort to provide users with the best and most relevant search results.

Since its establishment in 1998, Google has undergone a substantial transformation, continuously enhancing and altering how users interact with the vast quantity of information available online. Changes to Google’s algorithm have been crucial to this development. These advancements, which directly affect website rankings and business online presence strategies, have taken the lead in SEO updates.

The “Content is King” update. One of the first significant algorithmic changes to prioritise content quality was the Panda update. Its purpose was to demote content-poor websites, like thin affiliate pages and information that is repeated.

2012 – Penguin

The goal of the Penguin update was to stop the use of spammy link-building strategies. Websites with artificial backlinks—such as those derived from link farms and sponsored link exchanges—were penalised.

SEO and organic traffic

2013 – Hummingbird

The Hummingbird update significantly changed the way Google’s search algorithm functions. It brought about a novel method of deciphering the meaning of search queries, enabling Google to deliver more thorough and pertinent results.

2015 – RankBrain

2015 – Mobilegeddon

This update was rolled out to guarantee mobile-friendliness as a criterion for ranking. Google prioritised mobile-friendly websites with the release of the Mobilegeddon update in response to the increase in mobile users. Businesses entered the mobile-first era as a result of sites that were not optimised for mobile devices seeing a decline in ranks.

2016 – Possum

 Impact of algorithms on SEO

2018 – Medic

The goal of the Medic upgrade was to raise the calibre of search results for inquiries pertaining to health. Websites containing reliable, high-quality medical information were given greater weight.

2019 – BERT – Bi-directional Encoders for Transformers

BERT is a natural language processing system that aids Google in comprehending the intent behind search queries as well as their context. BERT is meant to improve how Google understands search queries. So if Google understands the query better that means Google is able to direct organic search traffic to the most appropriate web pages.

2020- Core Web Vitals

The Page Experience Update focuses on elements like page speed, mobile friendliness, and security that go a long way toward creating a great online user experience. New metrics that solely measure the experience of the users, Largest Contentful Paint (LCP), First Input Delay (FID), and Cumulative Layout Shift (CLS), were introduced.

2021 – Helpful Content Update

The Helpful Material Update is made to recognize and reward websites that create user-friendly, high-quality material. By rewarding content that meets visitors’ expectations, the helpful content system is able to reward useful content.

Google algorithm in today’s world

In 2023, Google algorithm changes still prioritise user experience and content relevance. AI and machine learning are essential for improving the readability of search results. The increasing prominence of voice search optimization and user intent is indicative of the evolving nature of user-search engine interactions.

2018 saw the release of the Mobile Performance Update, which increased the importance of mobile page performance in the search ranking algorithm.

In 2020, the Core Web Vitals update added three new factors to the search ranking algorithm: Largest Contentful Paint (LCP), First Input Delay (FID), and Cumulative Layout Shift (CLS). These metrics assess a website’s visual stability, interactivity, and loading speed. High-level search ranking variables were given additional weight in the revised Product Reviews.

Over time, Google algorithm changes have transformed the SEO environment and forced webmasters and marketers to modify their approaches to fit new requirements. Google has continuously worked to provide the greatest search experience, from promoting the production of high-quality content with Panda to thwarting dishonest link building with Penguin and figuring out user intent with RankBrain.
