Search engine optimization (SEO) algorithms are a set of rules and formulas used by search engines to rank web pages in search results. Here are some of the commonly known SEO algorithms:
Panda (2011)
The Panda algorithm of 2011! It was a game-changer, a force to be reckoned with, and a seismic shift in the world of SEO. It was the algorithm that shook the very foundations of the digital landscape and demanded that we all step up our game.
In the days before Panda, the online world was a wild and lawless place. Black-hat SEO tactics ruled the day, and the content quality was an afterthought. But with the arrival of the Panda, everything changed.
The Panda was the algorithm that put an end to the era of thin, low-quality content. It was the algorithm that demanded quality over quantity and forced us all to up our game. It was the algorithm that rewarded those who created valuable, informative content, and punished those who sought to cheat the system.
Impact on SEO:
The Panda was a wake-up call, a reminder that the digital landscape is not a lawless wasteland, but a place of order and structure. It taught us the importance of creating content that adds value to the lives of our audience, and the importance of building a brand that stands the test of time.
And so we honor the Panda algorithm of 2011, and the seismic shift it brought to the world of SEO. We embrace its power, respect its authority, and use it to guide us toward a brighter, more prosperous future. Within the world of SEO, anything is possible, and the only limit is our own imagination.
Penguin (2012):
Penguin (2012) refers to a major algorithm update that was released by Google in April 2012. The Penguin algorithm was designed to improve the quality of search results by penalizing websites that engaged in manipulative link-building practices to improve their search rankings.
Before the Penguin update, some website owners would engage in spammy tactics such as buying links or participating in link schemes in order to artificially boost their website’s authority and search rankings. However, these tactics were seen as unfair and manipulative, and Google introduced the Penguin algorithm to combat these practices.
Impact on SEO:
The Penguin algorithm uses a variety of factors to identify and penalize websites with low-quality or spammy links, including the relevance, authority, and diversity of the links. Websites that were found to be in violation of Google’s guidelines would experience a drop in search rankings and a decrease in organic traffic.
Overall, the Penguin algorithm was a significant update that helped to improve the quality and relevance of search results for users by reducing the impact of manipulative link-building practices. It has since been updated several times, with the most recent version being released in 2016.
Hummingbird (2013):
Hummingbird 2013 refers to a major algorithm update that was released by Google in August 2013. The Hummingbird algorithm update was designed to improve Google’s search results by providing more relevant and useful information to users, particularly for complex and conversational search queries.
Unlike previous updates which focused on specific aspects of the search algorithm, such as links or content quality, Hummingbird was a complete overhaul of the core algorithm, introducing new features such as the Knowledge Graph and semantic search.
Impact on SEO:
The update placed a greater emphasis on understanding the intent behind search queries, rather than simply matching keywords. This allowed Google to better interpret natural language queries and provide more accurate and helpful search results.
Overall, Hummingbird was a significant step forward in the evolution of Google’s search algorithm, and it has had a lasting impact on the way that search results are presented and accessed by users.
Pigeon (2013):
Pigeon (2013) is a major algorithm update that was released by Google in July 2014. The Pigeon update aimed to provide more relevant and accurate local search results by improving the way Google understood and ranked local search queries.

The Mobilegeddon update addressed this issue by giving a ranking boost to websites that were optimized for mobile devices, such as those that used responsive design or mobile-specific URLs. Websites that were not optimized for mobile devices were penalized in search rankings, which meant that they were less likely to appear in search results when users searched on mobile devices.
The Mobilegeddon update aimed to improve the mobile user experience by incentivizing website owners to optimize their websites for mobile devices. Since the update, the use of mobile-friendly design has become more widespread, and it has become an important factor in search rankings for Google and other search engines.
RankBrain (2015):
RankBrain (2015) is a machine learning algorithm that Google introduced in October 2015 as part of its search algorithm. The algorithm uses artificial intelligence to interpret and understand the meaning behind search queries and then uses that understanding to provide more relevant search results.
RankBrain is designed to improve the accuracy and relevance of search results by understanding the context and intent behind search queries, even if the query uses unfamiliar or ambiguous language. The algorithm uses machine learning to analyze patterns in search data and then applies that analysis to new search queries to provide more accurate results.
For example, if a user searches for “best pizza near me”, RankBrain can interpret the user’s intent as wanting to find a nearby pizza restaurant with good reviews, even if the user didn’t explicitly include those details in their search query. This allows RankBrain to provide more relevant and useful search results for users.
Impact on SEO:
Since its introduction, RankBrain has become an important factor in Google’s search algorithm, and it is believed to be one of the top three ranking signals used by Google. The algorithm has helped to improve the accuracy and relevance of search results, particularly for complex or ambiguous search queries.
Possum (2016):
Possum (2016) is a major algorithm update that Google released in September 2016. The update aimed to provide more accurate and diverse local search results by improving the way that Google’s algorithm handled search queries with local intent.
Prior to the Possum update, local search results were heavily influenced by the physical location of the searcher. This meant that businesses located outside of the city limits or in less-populated areas often struggled to appear in local search results, even if they were highly relevant to the user’s search.
The Possum update addressed this issue by giving greater weight to the physical location of businesses in relation to the user’s search location, as well as expanding the geographic range for certain types of local search queries. This allowed businesses outside of the traditional city limits to appear in local search results if they were relevant to the user’s search.
Impact on SEO:
The Possum update also improved the way that Google’s algorithm handled variations in search queries, such as misspellings or synonyms. This meant that businesses with similar names or keywords were less likely to compete directly with each other in search results.
Overall, the Possum update helped to provide more accurate and diverse local search results for users, as well as level the playing field for businesses located outside of the traditional city limits.
Mobile Page Speed Update (2018):
The Mobile Page Speed Update (2018) is a significant algorithm update that Google released in July 2018. The update aimed to improve the mobile user experience by giving a ranking boost to mobile-friendly websites with fast loading speeds, and penalizing those that were slow to load.
With more and more users accessing the internet on mobile devices, the Mobile Page Speed Update recognized the importance of mobile speed and user experience. Slow loading times can lead to frustration for users and result in high bounce rates, meaning that users are more likely to leave the website without engaging with it.
Impact on SEO:
The Mobile Page Speed Update encouraged website owners to improve the speed and performance of their mobile websites by giving a ranking boost to websites with fast loading speeds and penalizing those with slow loading speeds. This meant that websites that were optimized for mobile devices and had fast loading times were more likely to appear higher in search results than websites that were not optimized for mobile devices and had slow loading times.
The update aimed to incentivize website owners to improve the mobile user experience by optimizing their websites for mobile devices and improving their website speed. Since the update, website speed has become an increasingly important factor in search rankings, particularly for mobile devices.
Medic (2018):
Medic (2018) is a major algorithm update that Google released in August 2018. The update primarily affected websites in the health and medical industries and aimed to provide more accurate and reliable search results for health-related queries.
Prior to the Medic update, websites in the health and medical industries were often able to rank highly in search results by using certain tactics, such as including medical terminology or using specific keywords. However, this could result in less reliable and potentially harmful information appearing in search results.
The Medic update aimed to address this issue by giving greater weight to expertise, authority, and trustworthiness (E-A-T) factors in search rankings for health-related queries. This meant that websites with high levels of E-A-T were more likely to appear higher in search results for health-related queries, while those with lower levels of E-A-T were more likely to appear lower in search results.
Impact on SEO:
The Medic update also emphasized the importance of high-quality content and user experience for websites in the health and medical industries. This meant that websites with accurate and helpful information, easy-to-use interfaces, and a positive user experience were more likely to appear higher in search results than those with lower-quality content and user experience.
