Google's Search Algorithm Updates: When and What Changed

Google continuously updates its search algorithm to improve search quality and relevance. This article explores the major and minor updates to Google's search algorithm and how these updates affect search results.

Major Algorithm Updates

Google has made several significant updates to its core algorithm over the years, with major updates impacting search results and website rankings. The most recent major update was the March 2024 Core Update. This update, targeted at improving search quality, aimed to reduce low-quality and unoriginal content by approximately 40%, and introduced new policies to combat manipulative practices such as scaled content abuse and site reputation abuse. According to reliable sources like Search Engine Journal and Search Engine Land, this update has had a significant impact on search rankings, particularly reducing low-quality content.

On July 9, 2024, there was a noticeable spike in search ranking volatility. While not officially confirmed as an algorithm update, this suggests ongoing changes and optimizations. These dynamics indicate that Google remains vigilant in its efforts to continually improve search quality.

Historical Trends and Specific Updates

The most recent major search engine ranking update by Google occurred in June 2019. This update, also referred to as the June 2019 Core Update, aimed to enhance the overall quality of search results by incorporating more factors such as user experience, relevance, and authority. Websites that previously benefited from low-quality content or manipulative practices may have seen significant ranking changes. The June 2019 update underscores Google's commitment to providing users with the most relevant and high-quality search results.

Minor Updates and Tidbits

While Google frequently makes minor updates to its algorithm on a daily basis, these updates usually do not make significant changes to search rankings. However, in July 2018, Google experienced a major change in its algorithm. This change affected health and vehicles-related websites the most, leading to fluctuations in their search engine ranking positions. Although this update was significant, it was not a formal algorithm update as confirmed by the Google Search Team.
