Written text version of infographic: A Brief History of Google Algorithms

From start-up to world domination, Google has come a long way since its inception in the mid-1990s. This brief history of Google’s algorithm* updates sheds some light on how we got here.

*What’s an algorithm? A technical term for the formula Google uses to sort through billions of web pages to find what it believes to be the most relevant search results.

Florida – 2003

Released in late 2003, Florida was one of Google’s first major algorithm updates. It made keyword stuffing and other dodgy SEO tactics less effective, changing the search engine landscape forever. Many businesses lost rankings, leading to confusion and anger among users.

Big Daddy – 2005

Big Daddy was a major infrastructure update designed to improve the quality of search engine results. By altering URL canonicalisation, it fixed a ton of technical issues.

Vince – 2009

The Vince update worked in the favour of big brands. It made well-established organisations easier to find by making them appear at the top of SERPs.

May Day – 2010

This update changed the way long-tail keywords work. The main purpose of May Day was to crack down on low-quality sites ranking for long-tail queries.

Panda – 2011

Panda was a pretty big deal, ushering in a new era for Google. It demoted websites that lacked authority, sending high-quality sites to the top of SERPs.

Penguin – 2012

Penguin discouraged sneaky SEO tricks like keyword stuffing and buying links, preventing users from spamming search results.

Hummingbird – 2013

Named for its precision and speed, Hummingbird emphasised high-quality content by giving Google’s algorithm the ability to interpret full-question searches more accurately.

Mobile-Friendly – 2015

The mobile-friendly update made it (even more) worthwhile for website owners to optimise their sites for mobile devices. Websites with mobile compatibility started being rewarded with better rankings.

RankBrain – 2015

RankBrain is an artificial learning system. Google relies on RankBrain to interpret queries and filter search results accordingly. Since its launch in 2015, RankBrain has continued to develop and Google’s understanding of user behaviour is now stronger than ever.

Mobile-First – 2018

To cater for the rising number of searches being made on mobile devices, Google started rolling out its mobile first index in 2018. This update ranks search listings based on the mobile version of a site.
