Search engine result pages (SERPs) are significant for the growth and success of any online business and for driving traffic to their websites. However, digital marketing is becoming increasingly competitive and there are thousands of pages that are seeking a higher ranking. Ranking is a complicated process and is governed by algorithms.

Introduction to Google Algorithm

Google algorithm is a complex system used by Google to determine how pages will be ranked in the search results. Google’s main purpose is to provide the most relevant and high-quality results to its users. It uses algorithms to rank and index websites after analyzing them against multiple criteria. It considers hundreds of rules and factors such as content relevance, quality, user experience, etc. Google algorithm directly impacts the visibility and ranking so it is important for everyone in the digital marketing, web development, and SEO industry.

History of Google Algorithm

When Google was launched its algorithm was comparatively simple. It relied on PageRank and evaluated only the quality and quantity of links to a webpage for ranking it. This algorithm assumed that a site with more backlinks was more trustworthy. This algorithm had some limitations and over the years  Google algorithm has been constantly evolving. There are new updates every now and then to improve the user experience and search results. Some of the Google algorithms are:


A new Panda algorithm was launched in 2015 that assessed websites based on the quality of websites. This update focused on spammy links and low-quality content. This algorithm led to a decline in the ranking of many websites and emphasized website owners to produce high-quality and relevant content. 


This update was introduced in 2016 and was incorporated into Google’s core ranking algorithm. The unique thing about this algorithm was that it started individual page analysis and stopped penalizing entire websites for the spam signal. 


The Hummingbird algorithm was released in 2013 to emphasize semantic search. It specifically focused on offering personalized results on the basis of interests, location, and trends.


This Google algorithm was introduced in 2017 to target sites that were over advertising and used low-quality content to generate ad revenue. After this algorithm was released, sites started focusing more on valuable content.


The Pigeon Google search algorithm was released in 2014 to strengthen the connection between local search results and traditional ranking signals. This algorithm provided local businesses with better visibility.


Released in 2015, RankBrain introduced machine learning to help interpret the intent of search queries. This update boosted Google’s special SERP features. This Google algorithm improved managing the long-tail and ambiguous queries and rewarded websites that published content keeping the user intent in mind.


This Google algorithm was launched in 2018 and gave preference to mobile-friendly websites in mobile search results. This update targeted only those websites that were extremely slow. However, it did not significantly impact the rankings. 

The most recent updates in Google algorithm focus on user experience, E-A-T (Expertise, Authoritativeness, Trustworthiness), and integration of AI technologies to better understand the user intent. 

How Google Algorithm Works

The accurate details of how Google algorithms work aren’t public but there are certain factors that are used to assess the content ranking. Google crawls pages as a first step of its ranking process. It then determines what the page is about, and whether the content is of high quality or not. This is called indexing but not every page will be indexed. Only indexed pages are presented to users when they conduct a search. Pages are presented in a sequence by showing the most relevant and helpful content on top according to the Google algorithm. 

Some of the key ranking factors for the Google search algorithm are: 

  • Content relevance
  • Content quality
  • Backlinks
  • User experience
  • User engagement
  • Technical SEO 
  • Keywords
  • Context 

Impact of Google Algorithm on Search Engine Rankings

Any change in the Google algorithm impacts the search engine results and rankings. Algorithm updates significantly change a website’s position in search results. If digital marketers do not follow the updates and change their marketing strategies accordingly, it can have a very negative effect and can lead to a significant decrease in website traffic. It especially affects small businesses and content creators because they rely heavily on SEO to reach their target audience.

Updates like Hummingbird have enhanced Google’s ability to understand the user search intent in a better way. Keyword stuffing lowers the ranking of your website and only those pages are visible that use keywords naturally and in a meaningful manner. 

User Experience

User experience involves certain factors such as mobile friendliness, navigation, and page load speed are very important in determining the ranking of a website. The latest Google algorithm update like Core Web Vitals emphasizes a lot on user experience. Websites that load faster, are easier to navigate and are mobile-friendly are ranked higher. 


Google has changed its approach to evaluating backlinks while ranking websites. Now the focus has been sifted from quantity to the quality and relevance of backlinks. Google algorithms like Panda penalize websites with irrelevant and spammy backlinks.

  • Acquire high-quality backlinks from relevant and reputable websites.
