Google’s Major Algorithms, Updates and their effects on SEO

From a Digital Marketing point of view, it’s a vital and necessary to know all the Google updates and how Google Algorithm makes the search engine so accurate for the users. There are a lot of specific mathematics and logics behind these algorithms. We need to understand these very carefully. From SEO perspective, it is required to know why Google launches new update every now and then. It’s because Google always tries to improve the user experience. This is the ulterior objective. They work on providing a better result to the user to get the ultimate search satisfaction.

Google has modified its search algorithm a lot of times. These modification gives the business owners a challenge and a chance to rank higher in the search engines. Getting better rank has become a difficult task, but not an impossible one.

Let’s discuss the major algorithms and updates and their significant roles on Google search engine.


This algorithm defines the page rank of page A, which is determined by the page-rank of those pages which linked to page A. This system of ranking the pages was developed by Google’s founder Larry page and Sergey Brin at Stanford University. It is given by

PR (A) = (1-d) + d (PR (T1)/C (T1) + … + PR (Tn)/C (Tn))


PR (A) is the PageRank of page A,

PR (Ti) is the PageRank of pages Ti which link to page A,

C (Ti) is the number of outbound links on page Ti and

d is a damping factor which can be set between 0 and 1.

PageRank is nothing but a system of algorithms which calculates the link votes of a page from various sources. PageRank algorithm determines which pages are more valuable and which ones are less valuable per the above formula. Google uses PageRank algorithm along with text-matching technique to find pages that are both essential and relevant to your search.  


It is a web indexing system update through which Google provides 50% fresher search results than previous indexing system. Google rolled out the Caffeine update to completely reconfigure the search engine with an aim of better indexing, greater speed and more relevant search results. Google indexing process became so fast that search results were loading up to twice as fast as previous results. Pre-Caffeine, Google took a long time in indexing, crawling and ranking new pages or new content in a website. Post Caffeine update, Google started indexing so fast that the users started getting fresh and quick updates after any change in the web. Not only speed and size, Google Caffeine worked on the keywords relevancy as well. Search results became more accurate and relevant to the keyword you are searching for.


When we talk about Google algorithms, importance of Google Panda update cannot be ignored. After releasing this update many sites were brutally affected.

Google’s Penguin update is one of the major updates that have a huge impact on search engine. This was rolled out to demote sites using prohibited SEO techniques like & improper link building and keyword stuffingetc. Penguin penalized those unethical pages by decreasing their rank. It did not penalize the entire website. Google suggested the site owners to use ethical link building and use proper anchor text instead of worrying about Penguin updates. 

EMD (Exact Match Domain):

Google rolled out yet another important change in update, which provided the users better search results and experience. Post EMD update , spammy sites of having wrong content with improper URL structure were removed completely from the search results. To stand out in search engine, it’s required to remove all the content that is irrelevant to the keywords used in URL structure.


Google Pigeon is the local search algorithm update. The goal of this update was to increase the rank of local businesses in a search engine. This is helpful for the user who searches something locally and for the local business as well. The key part of this algorithm is to focus on location and distance, from which the users search. Post this update the local listing was getting more valuable to SEO entrepreneurs. This algorithm combines the web search and map search in a more copulative way.


Hummingbird – the name suggests being precise and fast. Google Hummingbird update was designed to understand the meaning of the whole search query. Hummingbird was implemented to focus on the whole keyword phrase accurately. It does not show value to the pages that matched the exact keyword without having no meaning. It was just a change in process to calculate the search results in a better way. Google should give importance to those pages having original and high-quality content in a structured way. Post this update, semantics started playing a huge role in creating content.


A modified version of Hummingbird update is RankBrain . It is an artificial intelligence program to help Google in processing the search results more accurately. It’s a machine learning technology which converts a huge amount of written language into mathematical form. Google RankBrain algorithm update is a part of Google’s overall search algorithm that is used to find the pages exactly relevant to the particular keywords.  So create more content on the focused keywords and links them from the high authority pages is the best way to stand out in the competition.

Mobile friendly:

Penguin was one of the bigger changes in algorithm after the Panda Update. Many sites generated negative SEO to get better ranking in search results. It is the process of using black hat and illegal techniques downgrade the competitor’s ranking in search engine. This type of unethical work proved very harmful for other competitors who follows the correct methods to get legitimate backlinks to improve their rank and get traffic to their website. Day by day the spam was increasing and then Google introduced a solution to get rid of it. Google rolled out Penguin update to penalize the spammy links and drop the ranking of the sites which build low quality links in their webpages. Post this update 3% of the search queries were affected

Google Penguin Update

The main motive of this Google update was to catch the excessive spammers and block them from getting high search rankings.

Otherwise, although at a certain point of time they got the ranking, but after certain change in update, the ranking suffered and so did the traffic.

Penguin, The web-spam algorithm update: Launched on 24th April 2012

After the improvement of search quality for the user by implementation of Google Panda Update, Google focused on improving Link quality. Google Penguin update was for those sites which used black hat SEO techniques to get better search rankings. Black Hat SEO are techniques by which sites get huge benefits by doing unethical SEO work such as keyword stuffing, adding wrong anchor text, getting links from spammy websites etc. Those sites were penalized massively for not following Google guidelines. Intention of this update became successful when site owners started focusing on making good quality content for their sites rather than doing over optimization.

Penguin 2: Launched on 25th May 2012

Like the Google Panda, Google launched an update for refreshing Penguin data as well. It did not affect the search results that much but structured and updated the data of all low quality sites. By this process Google started another step to remove all the sites which violated the search results and harmed the search quality.

Penguin 2.1: Launched on 5th Oct 2012

Industry waited for this update so eagerly but it did not have a huge impact. It was a minor data update.

To fight strongly with web spam, Google Launched another Spam Filtering algorithm Penguin 5, which was an updated version of Penguin 4.

It became hard to tell Google that which keyword we wanted to target the most. Keywords stuffing was became valueless. Google stopped giving priority to the false linked pages and rather started showing links which used correct anchor text into their sites with high quality content. Pre Penguin update, people buying links in a short period of time and got higher ranking irrespectively. Google penalized all those illegal link building sites and the pages as well.
