The Evolution of Google's Search Algorithm and Ranking Changes

The Evolution of Google's Search Algorithm and Ranking Changes

Google Search Algorithms function as complex computer programs designed to determine the sequence of search results displayed on Google. This powerful tool sifts through billions of web pages, serving as the backbone of the internet's core.


Think of these algorithms as rules that consider many ranking factors to identify how Google manages pages in their search results. Their primary objective is to present users with the most optimal and pertinent results for their search queries.


 In an ongoing effort to refine the user experience, Google consistently updates and improves its algorithms. 


This includes looking at many things, like backlinks, usability, and keyword mentions. It involves considering a lot of factors to make sure search results are accurate and valuable.


Google's algorithm is very intricate, and its precise workings are unknown. There are reportedly far over 200 ranking variables, and all of them can't be tracked.


Even if people find the working of algorithms it won't matter because the algorithm is always changing. As Google evolved, developers concentrated on preventing cheating and finding ways to prioritize the most relevant links for users. Their main goal was to enhance the relevance of search results for consumers. Nowadays, the algorithm takes into account hundreds of variables to achieve this.


According to Google, thousands of updates are made to its search algorithm annually. Google makes algorithmic changes that are too small for users to detect most of the time. However, Google occasionally makes a fundamental shift that permanently alters the way the SEO performs.


In the past, the Google algorithm used to change significantly. Your website might remain at the top of the list for a specific term until the next update, which could happen after weeks or even months. Then, a new update would be released, and everything changes. That's how things would stay until the next update.


Let's review the most important changes to search algorithms. Exploring why these updates were made, how they work, and what adjustments were suitable to make the best SEO strategies.


Florida Search Algorithm

This update was first released in November of 2003. The update aimed to help websites rank higher on Google's search results, causing a big change in how websites were rated.


In the 2000s, low-quality and spammy websites were widespread. The main objective of the Google Florida Update during that period was to prevent such websites. The aim is to give lower ratings to websites of low quality on the internet while boosting those with a strong online presence and informative content.


However, predicting the long-term impact of the Google Florida Update on website owners is challenging with this search algorithm. Although the change may have helped certain websites in the short run, it's impossible to predict if their rankings will stay stable over time.


To maintain a higher website ranking, website owners should concentrate on creating high-quality content and establishing a strong online presence. This might include interacting with consumers on social media, building a strong backlink profile, and ensuring the website is user-friendly.

 Panda Search Algorithm

Launched in February 2011, this algorithm update aimed to regulate page quality by introducing a scoring system that later affected the ranking factor. Initially, the effects of the Panda Search Algorithm was not an important update.


However, Google permanently integrated it into its main algorithm in January 2016. Following this integration, there have been subsequent update rollouts, speeding the frequency at which Panda penalties and recoveries occur.


For this ranking system, It is recommended that you keep a close eye on the website page for any signs of keyword stuffing, low-quality content, or copied material.


It is important to ensure that the content on your website is original, informative, and relevant to your audience. By doing so, you can improve your website's search engine rankings and provide a better user experience for your visitors.

 Penguin Search Algorithm

The Penguin Search Algorithm first appeared in April 2012. The goal of Google Penguin is to rank websites lower with dodgy backlink profiles. This upgrade eliminates low-effort link-building practices, such as purchasing links from PBNs and link farms.


A link to your website is like a vote for it. A reputable website linking to yours is a recommendation for your website. A vote from a small, unrecognized website will have less weight than a vote from a reputable website.


Even yet, a sizable number of these shady votes can have a significant impact. Because of this, SEOs used to strive to obtain as many links as they could from every source. Anchor text is another element that matters to the penguin algorithm. We call the highlighted text in a link "anchor text."


Although the precise components that the Penguin algorithm considers are unknown, we do know that it is looking for links of low-quality or self-made links. This implies that Google will be less likely to trust your entire website if the Penguin algorithm finds that a significant portion of the links pointing to it are not reliable. As a result, the website's ranks will drop overall.


Hummingbird Search Algorithm

This update was published in August 2013. Google uses the Hummingbird algorithm to better understand search queries and deliver results that are relevant to the searcher's intent rather than just the specific phrases used in the search term. 


The Hummingbird algorithm allows a website to rank for a query even if it doesn't include the precise terms for the searcher input, even if keywords are still crucial. Natural language processing, which makes use of synonyms, co-occurring phrases, and latent semantic indexing, helps achieve this.


Having proper keywords is crucial for this algorithm. When researching keywords, it's important to focus on the underlying ideas. Take time to analyze synonyms, similar queries,relevant content, and related phrases. 

You can find ideas on Google Related Searches, Google Related Questions, and Google Autocomplete recommendations. These tools are great resources to help you find the right keywords for your research.


Pigeon Search Algorithm

Google announced an algorithm in 2014 that connected local search results to other ranking factors and increased their accuracy. Web searches and Google Maps searches both reveal this.

 Before the introduction of Pigeon, traditional SEO criteria did not influence the ranking of local results. Consequently, local businesses need to invest more time and resources in their SEO strategy on their websites and other online platforms, especially business directory sites.


Additionally, Pigeon causes Google to rank companies with a location and distance most relevant to the user. Google's fundamental algorithm is more brilliant than ever, changing local listings in the search results and giving local directory sites the top places.


Mobile-first indexing algorithm

Google updated its algorithm in April 2015, giving mobile-friendly webpages a higher ranking than desktop ones. Websites with poor mobile usability or display received lower rankings.


This now emphasizes your website's mobile version rather than its desktop version due to further mobile search improvements. These days, Google gives each website a ranking determined by how quickly and easily navigable its mobile version is.


It is important to ensure that your website is compatible with mobile devices, and one way to test this is by using Google's Mobile-Friendly Test. 


When creating a website, it is important to choose a web host, design, and content layout that is all mobile-friendly to ensure optimal user experience on mobile devices.


RankBrain Search Algorithm

In October 2015, RankBrain was introduced as an extension of the Hummingbird update to address three issues with search engine results. These issues could have been better user experience, low-quality content, and weak relevance to the search query. 

 By using machine learning, RankBrain aims to understand the meaning behind search queries and improve the quality of search results.


Use competitive analysis to optimize your pages for accuracy and relevancy. If you can include keywords in your content, your search validity will improve significantly. With the optimization, the algorithm will provide a better ranking position in SERP. 


Medic Search Algorithm

Updated in May 2018, the Google Medic update seemed to have an unfair impact on websites dealing with crucial decisions, especially those related to health.

 Google officials have mentioned that some E-A-T (expertise, authority, and trust) signals from the Quality Rater Guidelines paper were used in the update, although it hasn't been directly confirmed.


Currently, there isn't a proven recovery strategy for the Medic update. Some SEO experts suggest creating entities for your brand, while others recommend hiring professional writers for accuracy on your website.


However, looking at the facts, building your backlink profile appears to be the only surefire strategy to increase your website's authority.


Bert Search Algorithm

The October 2019 update focuses on identifying and reducing poorly written and aimless content that lacks context. It promotes well-written content, mainly using natural language processing.

 The result of earlier releases such as RankBrain, Hummingbird, and Panda, is BERT. It enables Google to comprehend far more detail in search results and requests alike.


This means that it is important that you focus on good writing. It implies that you should write in an explanatory manner and avoid using a lot of unnecessary words.


When writing a blog, it's a good idea to carry out entity research as well. Including important entities in the content helps it make sense.


Core Updates Search Algorithm

In 2017, Google started labeling significant updates as "Google core updates." Since then, understanding the details of these updates and the specific areas of search they aim to improve has become more challenging.

After an update, SEOs would often watch for changes in rankings and try to figure out the exact reasons, but clear conclusions were seldom reached. Google's core updates might be improvements over previous releases or perhaps a series of related but smaller updates.


One way to assess the impact of Google core changes is by tracking the SERP (Search Engine Results Page) history for the terms you are targeting, as the effects of these changes are often unpredictable. After the update is released, you can check if your website's ranking has increased or decreased. You can also try to figure out why these changes occurred.


Understanding Google Algorithm Updates is crucial because they have the power to alter how search results are displayed and ranked. This affects how much people see and notice websites and businesses, making it crucial for their success.

To keep their rankings high on search engines, SEO experts and companies need to stay updated on the latest changes and adapt their strategies accordingly.


Although the Google algorithm's inner workings are unknown. Identifying some factors includes the following:


A searchable website often ranks better for relevant keywords the more frequently those keywords appear on the page. In addition to the body content, keywords must also be present in the page title and meta title. 

Although you may improve your pages to include more relevant keyword mentions, including too many of the same keywords at once might be harmful. Try to avoid keyword stuffing by including keywords organically in your wording.



Your website may rank higher in search engine results pages when it has links from topical authority websites to your pages. For instance, a blog article on a trustworthy website or excellent product evaluations regarding your content may contain hyperlinks. 


To increase your chances of obtaining backlinks, produce informative and engaging content that other trustworthy websites will want to connect to. 



The algorithm gives newer pages a higher ranking. However, since this is a context-dependent element, certain blog entries might still be useful even if they aren't the most recent. 


Because it performs better on other metrics, an older page may rank higher than a newer one. To keep your content fresh, make sure to regularly check and update it for accuracy. Additionally, update any popular components as needed.

 Page experience

Google values user experience (UX) greatly. The algorithm looks for meta tags that match the content of pages, assesses how easy it is to navigate a website, assesses how quickly pages load, and looks for mobile accessibility.

To ensure a pleasant user experience, avoid using high-pixel images that take a long time to load or overwhelming your web pages with advertisements.

 Knowing how the Google Search Algorithm gives a huge advantage for the SEO of the pages that you have created. Knowing how the Google Search Algorithm works gives you a big advantage when you're trying to make your pages show up better in searches. It helps you understand what the algorithm likes, so you can make your content and website better to get more people to see it.
