Google Algorithm Updates & Changes: A Complete History

Insight

Providing a complete history of Google algorithm updates and changes would be extensive, as Google continuously updates its algorithms to improve search results and combat spam. However, here's an overview of some of the major algorithm updates that have occurred over the years:

Google Panda (February 2011): Panda aimed to penalise websites with low-quality or duplicate content and reward those with high-quality, original content.

Google Penguin (April 2012): Penguin targeted websites using manipulative link-building tactics, such as buying links or participating in link schemes, to artificially boost search rankings.

Google Hummingbird (August 2013): Hummingbird introduced a new search algorithm that focused on understanding the context and intent behind search queries rather than just matching keywords.

Google Pigeon (July 2014): Pigeon aimed to provide more relevant and accurate local search results by improving the ranking signals for local businesses.

Google Mobile-Friendly Update (April 2015): This update, also known as "Mobilegeddon," prioritised mobile-friendly websites in mobile search results, rewarding sites with responsive design and penalising those with poor mobile usability

Google RankBrain (October 2015): RankBrain is a machine learning algorithm that helps Google better understand the meaning behind search queries and deliver more relevant search results.

Google Fred (March 2017): Fred targeted websites with low-quality content and aggressive monetisation tactics, such as excessive ads or affiliate links, that provided little value to users.

Google Medic Update (August 2018): The Medic Update appeared to target health and wellness websites, causing significant fluctuations in rankings for many sites in these industries.

Google BERT (October 2019): BERT (Bidirectional Encoder Representations from Transformers) is a natural language processing algorithm that helps Google better understand the context of search queries by considering the full context of a word by looking at the words that come before and after it.

Google Core Updates (ongoing): Google regularly releases broad core algorithm updates that can significantly impact search rankings. These updates are designed to improve search results' overall quality and relevance.

These are just a few examples of the major algorithm updates Google has rolled out over the years. Website owners and SEO professionals must stay informed about these updates and adapt strategies to maintain or improve search rankings.
