Google Algorithm And Its Major Updates…. 

Every time you search, there are thousands, sometimes millions, of web pages with valuable information. How Google features out which results to display starts long before you even type, Even before you search, Google classifies information about web pages in the Search index. The index is like a library that contains more info than in all the world’s libraries put together.

To help you find what you’re looking for quickly, Google provides results in many useful layouts. Whether presented as a map with directions, images, videos, or stories, Google is constantly expanding with new ways to present information.

Google search algorithm is a complex system that authorizes Google to find, rank, and return the most suitable pages for a specific search query. To be precise the entire ranking system consists of multiple algorithms that examine various factors such as quality, relevance, or usability of the page.

How does it work?

These ranking systems are composite of not one but an entire series of algorithms. To give you the utmost useful information, Search algorithms look at many elements, including the words of your query, relevance, and usability of pages, the expertise of sources, and your location and settings. The value applied to each factor varies depending on the nature of your query, for example, the freshness of the content plays a major role in answering queries.

  • Crawling: The crawling process works with a list of web addresses from prior crawls and sitemaps provided by website owners. As Google crawlers visit these websites, they use links on those sites to determine other pages. The software pays special attention to the new site, changes to existing sites, and dead links. Computer programs determine which website to crawl, how frequently, and the various pages to fetch from every site.

  • Indexing:Indexing is a process by which search engines classify information before a search to facilitate super-fast responses to queries.

In simple words, indexing is a process of adding web pages within Google search. Searching by individual pages for keywords and topics would be a pretty slow process for search engines to recognize relevant information. Instead, search engines (including Google) use an inverted index, also known as a reverse index.

  • Ranking: Rankings in SEO refer to a website’s position on the SERP,  Various ranking parts influence whether a website looks higher on the SERP based on the content relevance to the search term, or the variety of backlinks pointing to the page.

Major Updates Of Google Algorithm

Google claims to modernize its search algorithm numerous times per year. In the entire majority of cases, Google algorithm updates are too short to remark. But, every once in a while, Google proposes a change that disrupts the way we do SEO forever.Why these updates were introduced, how they work, and what changes we had to make to our SEO policies in response.

1.Google Panda. 

Date: February 24, 2011

 It is a significant variance to Google's search results ranking algorithm that was initial published in February 2011. The change proposed to reduce the position of "low-quality sites" or "thin sites", indistinct, "content farms", and produce higher-quality sites near the top of the search results.

The affirmed intent of the Google Panda algorithm update is intended to reward high-quality websites and decrease the presence of low-quality websites in Google’s organic search engine results.

 Google’s Panda Update is a search filter introduced in February 2011 meant to prevent sites with poor quality content from working their way into Google’s top search results. Panda is updated from time to time.

 When this occurs, sites previously hit may emerge, if they’ve made the right changes. Panda may also catch sites that disappeared before. A refresh also indicates “false positives” might get published Google got a big sufficient earnings hit via some allies that Google needed to reveal Panda as a material impact on an earnings call. 

I believe it was the right decision to launch Panda, both for the long-term trust of our users and a greater ecosystem for publishers."

Google's Panda admitted certain updates after the original rollout in February 2011, and their impact went global in April 2011. 

2. Penguin.

Date: April 24 2012

The main function of this algorithm is to fall the websites using spam or black hat techniques, like keyword stuffing and forbidden link-building practices, to rank high on search engines. Penguin algorithm punishes any website that doesn’t obey guidelines laid out by Google Webmaster.

  • Low-quality, “link farm” websites were growing — websites whose only goal was to place links or sell links. Links were becoming an end in themselves rather than a naturally developing means of rolling up in organic rankings.

  • Links were being created by bots or tools, and thus did not symbolize that humans found the target web page’s content helpful.

  • Rather than links developing naturally over time, Google was examining large spikes in links, a clear indication of manipulation.

  • Companies were writing off-site articles and press releases of indecisive quality a mile a minute, simply to obtain links and with no purpose of actually improving a reader understand a topic more clearly.

  • Websites were infiltrating into reciprocal or group link replacement programs, again designed strictly to build the number of links for the members.

  • Various on-site methods were spiraling out of control. The most definite problem was the trend of setting up footer links to most or all of a site’s internal pages — this method created a lot of links, but went in the form of a user experience.

3.Humming bird

 Date September 27, 2013

The upgrade was considered the most significant variance to Google search in years, with more "human" search interactions and a much higher focus on conversation and meaning.

 Thus, web developers and writers were inspired to optimize their sites with original writing rather than forced keywords and make effective use of specialized web development for on-site navigation.

They were also encouraged to make efficient use of technical website features, such as page linking, on-page elements including title tags, URL addresses, and HTML tags, as well as addressing high-quality, relevant content without duplication.

 While keywords within the query remain to be important, "Hummingbird" adds more depth to long-tailed keywords, efficiently catering to the optimization of content rather than only keywords.

“Hummingbird is handling more consideration to every term in a query, assuring that the whole query – the entire sentence or conversation or meaning – is taken into account, rather than selective words. The goal is that pages matching the meaning do better, rather than pages matching just a few terms.

4.Google Pigeon.

Date: July 24 2014

To ultimately enhance its local search abilities, Google improved hundreds of ranking signals for both Google Search and Google Maps. This also indicated Google’s location and distance ranking parameters were also updated to better provide local, related results to users based on proximity.

And it did, for the most part, mainly for the long term.

Local search has improved drastically since July 2014, when the first Pigeon launch took place, but it is also generally believed that a series of Pigeon updates have been applied since then, too. And that would tell some of the hiccups at the beginning of the algorithm update launch that was eventually corrected.

Also, to enhance cooperation between local ranking signals, Google updated how it manages consumer-driven local “directories,

The purpose of Pigeon, was to make local search resemble traditional organic search as much as possible, while also performing similarly.

Earlier small and local businesses had the privilege of being “local” and would arrive in results for people who were searching within their proximity. According to Search Engine Land, as Google joins local results more firmly to standard web ranking signals we can anticipate bigger sites to rank better than other local-type businesses.

5.The Google Mobile.

Date: April 21 2015

The Google Mobile Update (nicknamed “Mobilegeddon”) formally incorporated mobile-friendliness as a ranking signal. The update prioritized mobile-friendly websites on mobile SERPs, and the sites that weren’t mobile-friendly were either punished or removed from the SERPs altogether.

Mobilegeddon was yet another attempt by Google to continue providing the best possible search experience for its users. “When it comes to search on mobile devices, users should get the most suitable and timely results, no matter if the information lives on mobile-friendly web pages or apps,” Google announced in 2015.

Mobilegeddon punishes websites that aren’t mobile-responsive and rewards those that are. It only hits mobile searches and only web pages (not entire websites), and it affects queries and websites globally, in every language

Google is now using this label as a ranking factor over all languages globally; the update applies to individual pages, not entire websites.

 As a result, searchers get “high-quality and related results where text is readable without tapping or zooming, tap targets are spaced properly, and the page withdraws unplayable content or horizontal scrolling..

6. Google RankBrain.

Date: October 26 2015

The Google RankBrain Update was part of Hummingbird. RankBrain is a machine-learning powered element of Google’s algorithm that manages to better experience searcher purpose and deliver the most accurate, relevant SERP results.

Many SEO strategists consider it serves to measure how searchers interact with search results and then rank the results respectively. (This could explain why your SERP looks distinct when you search for the identical thing several times.)

It has also been theorized that the RankBrain algorithm classifies relevance features for the websites that rank for a given query, building query-specific ranking factors and signals.

Google has called RankBrain the third-most significant ranking signal.

RankBrain is a system by which Google can better understand the possible user purpose of a search query. It was rolled out in the spring of 2015, but not published until October 26 of that year.

In beginning, RankBrain was applied to queries that Google had not previously met which valued then and still do, for about 15% of all searches. It was extended from there to impact all search results.

At its core, RankBrain is a machine learning system that strengthens Hummingbird, which took Google from a “strings” to a “things” environment.

7. Google Medic

Date: May 4 2018

Google’s Medic Update was a push for the search engine giant to help increase the classification of authority and expertise online. This is done through the algorithm’s core ranking factors to assure that quality, reliable and proficient content is getting ranked in the search results.

Websites that display high-quality content were rewarded by the Medic update. Quality content is scored on Expertise, Authority, and Trustworthiness, known as E-A-T factors. Let’s take a look at what that means.

For content to be considered ‘expert’, it needs to be produced by someone with the appropriate credentials. Content that suggests such credentials will be rewarded.

For content to be considered as ‘authority, it must show that it was written by people with expertise. Expertise can come from qualifications and experience, so content that shows such information will be rewarded.

Content with the ‘reliable’ factor displays components that show visitors they are in the right place, and they can rely on what they read.

Focus on E-A-T: Expertise, Authoritativeness, and Trustworthiness

“Expert” – You need to be an expert in the field that your website is concentrated on. Keeping an up-to-date “testimonial” or “reviews” page on your website is a way of explaining to Google that you are an expert on your topic because you are getting feedback from third parties.

“Authority”– You want to tell that your website is an authority on your topic. This differs from being an “Expert” because you are displaying your credentials proving your position or experience in your field that shows in your content, by presenting material that answers your readers’ questions and helps them resolve a problem, the search engines will credit your website as being an authority on your subject. An auto repair shop that has approved trained mechanics will want to have their certifications placed prominently on the website.

“Trust”– You need to show users they can trust the website they are on. This is mainly important for eCommerce websites that ask users for their credit card information. Everything regarding your site should make users feel safe while they’re visiting. Be sure your site uses a legitimate payment processor with proof that it is secure for customers to utilize.

8.Google Core Update

Date: September 24 2019

A core update is a vital change Google makes to its ranking algorithm that affects a huge number of indexed web pages. They happen about once every two or three months on average. Core updates are designed to enhance the quality and relevance of Google's search results by rearranging the search rankings of indexed web pages.

Core updates can drastically change search engine optimization (SEO) for Google. The underlying philosophy of Google SEO is to customize your website, as well as its presence so that it's approved by Google's ranking algorithm.


All the time, energy, and resources you spent on optimizing your website for Google could be repealed following the rollout of a core update. A core update, for case, may eliminate the otherwise actual impact of a ranking signal targeted by your website. With the ranking signal no longer in play, your website's search rankings will fall.

Core updates can even impose penalties that destroy your website's search rankings. The Panda update, for example, imposed an automated and algorithmic penalty on websites with weak content. Earlier to its rollout, webmasters could simply rank their websites high on Google without publishing much content. The Panda update modified the game by punishing websites such as these for thin content.

Some core updates hit more than just search rankings; they restructure Google's search engine results pages (SERPs). Google utilizes core updates to add, remove and change alternative listings in its SERPs. Alternative listings consist OF nonpaid properties like People Also Ask (PAA) listings, highlighted snippets, and Knowledge Graph panels.


Google rarely gives any sign of the variations in its algorithms except they are major. Smaller changes are made within and are ordinarily not felt except as smaller ripples. It’s vital to stay alongside Google’s algorithm releases, but it’s just as important not to overthink the algorithms or try to “game” them

Instead, it’s necessary to simply acknowledge the power the Google algorithm has, and try to produce the best website possible. Consequently, visitors will be happy with what they see, which is always a positive ranking signal.
