A History of Google Algorithm Updates
BERT Update – October 2019
Allegedly one of the biggest changes to Google search in the past 5 years, the BERT update focused on better understanding search queries. Google’s official explanation was:
“These improvements are oriented around improving language understanding, particularly for more natural language/conversational queries, as BERT is able to help Search better understand the nuance and context of words in Searches and better match those queries with helpful results.
Particularly for longer, more conversational queries, or searches where prepositions like “for” and “to” matter a lot to the meaning, Search will be able to understand the context of the words in your query. You can search in a way that feels natural for you.”
Broad Core Algorithm Update – September 2019
Broad updates don’t tend to target anything specific, instead, they improve the overall effectiveness of Google’s systems. This can lead to drops or gains in ranking and the main advice from Google is to focus on producing quality content. These updates won’t penalize any websites but they will reassess any new content featured in search results since the last update, and possibly rank quality content higher. Content improvements can aid recovery from any drop in ranking.
Core Update – June 2019
In a rare move, Google announced they would be releasing a new update prior to rolling it out. The update is thought to have affected low-quality news sites while boosting trusted aggregator sites. It may have also affected video carousels, with many YouTube channels seeing 25% increases in traffic.
Fred Update – March 2017

Pigeon Update – July 2014
Google’s Pigeon was released on 24th July 2014. This Google algorithm update, unlike its predecessors, was designed to give more accurate and relevant local search results. Google rewarded local businesses that had a strong organic presence with better visibility in traditional search results. Several updates on Pigeon have been made since 2014.
In many ways Pigeon can be described as not being punitive, rather, it serves a specific group of users best.
Other honorable Google algorithm updates include:
Hummingbird Update – August 2013
This was launched on August 22nd 2013. The name Hummingbird came from the speed and precision of the update. This new algorithm allows Google to better understand phrases, providing precise results to complex search queries. It expands brand content strategy so as to have more informational content on their site. In addition, it gives substitutions as a user enters the query. It also brings out results far more complex search queries. Google’s knowledge graph also appears more often than it did previously giving more direct answers in search results.
Hummingbird has improved how users are sent to a specific page and directed to the information they are seeking. Hummingbird has also promoted voice-powered searches, helping to create a smarter search engine that is able to better decipher user intent. Hummingbird update has been branded “the heart of Google’s search engine” as it can filter billions of pages to find the most relevant search results.
Penguin Update – April 2012
This was launched on April 24th 2012. This update specifically targeted link spam as well as manipulative link building practices. Matt Cutts, head of the Google web spam team officially announced the update via Twitter as the Penguin Algorithm Update. It was an extension to the Panda Update and was Google’s response to the increasing practice of black hat search engine optimization techniques which are used to gain higher search rankings in ways that violate search engine guidelines. A number of updates were made to the Penguin algorithm since its launch in 2012 including;
Google Penguin 1.1(March 26, 2012)
Google Penguin 1.2 (October 5, 2012)
Google Penguin 2.0 (May 22, 2013)
Google Penguin 2.1 (October 4, 2013)
Google Penguin3.0 (October 17, 2014)
Google Penguin 4.O (September 23, 2016)
With the last update, Penguin became a part of the core algorithm, meaning it evaluates websites and links in real-time.
Panda Update – February 2011
Panda was launched in February 24th 2011. It was aimed at dealing with quality and optimization issues that the search engine identified in a number of websites indexed at the time. It assigns a quality score to webpages which is then used as a ranking factor. The Panda Update is also known as the Farmer Update. When this update was implemented it had a huge impact on a broad range of companies that operated online. Panda was introduced to improve search quality by eliminating prevailing content farms as well as spam sites that were designed to take advantage of Google’s vulnerabilities.
Panda has great at cleaning up low-quality sites that occupy valuable SERP real estate. The update did not come without it share of problems, especially for companies with e-commerce initiatives. Sites both big and small started disappearing from their usual keyword ranks they had previously owned for years. Lots of companies were impacted negatively and were completely unable to recover traffic.
Numerous updates have been made to the Panda Update, with most of them focusing on eliminating obstructive spam sites. These Panda updates have focused on getting advertisers to achieve their maximum search potential.
