the latest Google Algorithm

Currently, maybe many website owners, bloggers and people who are interested in SEO want to know what the Latest Google Algorithm for SEO is, what are the references so that the website can be on page 1 of search results. So, on this occasion, we will discuss Google’s Latest Algorithm for SEO in 2021.

But before that, we will explain first what the Google Algorithm is and what types of Google algorithms have been previously updated by Google. Please listen to the end.

What is the Google Algorithm?

Google’s algorithm is a complex system used to retrieve data from a search index and immediately provide the best results for queries. Search engines use a combination of algorithms and various ranking factors to provide web pages that are ranked based on relevance on the search engine results page (SERP).

In the early years, Google made only minor updates to its algorithm. Now, Google makes thousands of changes every year.

Most of these updates are so minor that they go completely unnoticed. However, sometimes the search engines launch major algorithm updates which significantly affect the SERPs for example as we will discuss today.

Types of Google Algorithms

Below we will explain several types of Google Algorithms as learning materials for you in the future.


This algorithm was released by Google on February 24, 2011

Dangers: Duplicate / plagiarized content, spam or unqualified content, keyword stuffing.

How it works: This update to the Panda algorithm assigns a so-called “quality score” to web pages. This score is then used as a ranking factor. Initially, the Panda effect was mild, but as of January 2016 it was permanently incorporated into Google’s core algorithm. Since then, update launches have become more frequent, so Panda penalties and recoveries are now happening faster.

How to Adjust: Run regular site checks for duplicate content, spam content, unqualified content and keyword stuffing. To do this, you will need a site crawler or other tool that can check this. For example SEMrush for paid ones. To check plagiarism content, you can use Copyscape . In addition, make sure your articles or content are not copied from other websites.


This algorithm was released by Google on April 24, 2012

Hazards: Links are spammy or irrelevant; links with overly optimized link text.

How it works: The goal of the Google Penguin Algorithm is to lower the rankings of sites whose backlinks appear unnatural. This update ends the creation of illegal backlinks, such as buying links from link pools and PBNs.

How to Adjust: To stay safe from the effects of updating the Google Penguin Algorithm, keep an eye on your backlink growth and run regular audits with a backlink checker like SEO SpyGlass or SEMrush. In the dashboard, you will find a growth chart of your link profile. Watch out for unusual spikes; it may be the result of negative SEO attacks by your competitors.

If you find a link that is dangerous or spam, add it to the disavow file, download it, and upload it to the Disavow Link Tool .


This algorithm was released by Google on August 22, 2013

Dangers: Keyword stuffing or excessive keyword stuffing and low quality content.

How it works: The Hummingbird algorithm helps Google better interpret search queries and return results that match the user’s intent (as opposed to individual terms in the query). While keywords are still important, the Hummingbird algorithm allows pages to rank for queries even if they don’t contain the exact words entered by the user. This is achieved with the aid of natural language processing which relies on indexing of latent semantics, concurrent terms, and synonyms.

How to Customize: Expand your keyword research and focus on the concept behind keywords. Carefully analyze related searches, synonyms and co-occurring terms. In addition, make sure that your content is useful and doesn’t include too many of the same keywords over and over. Prioritize quality over quantity.


This algorithm was released by Google on April 21, 2015

Danger: The website is not mobile responsive

How it works: Google ranks all websites based on how fast and user-friendly their mobile version is. So a website that is not mobile friendly and not user friendly will be less likely to be on the first page of the search.

How to Adjust: Optimize your page for mobile search and focus on speed and usability. It is mobile friendly and Google’s page speed test will help you see which aspects of your page need improvement. You can check your page’s mobile optimization as part of your overall website audit.


This algorithm was released by Google on October 26, 2015

Dangers: Lack of query-specific relevance; Bad UX .

How it works: RankBrain is a Google Algorithm like machine learning system that helps Google understand the meaning behind a query and present the search results best suited to respond to the query. Google calls RankBrain the third most important ranking factor. This algorithm has a function to display more accurate search results on Google. Examples that are of poor quality or are too shallow to present to readers.

How to Customize: Optimize your pages for relevance and completeness with the help of competitive analysis. You can research using the tools to find an entire list of relevant terms, words and concepts used by a large number of your top-ranking competitors. Find a way to add this word or term to your content and you will see the relevance of your search increase dramatically.


This algorithm was released by Google on May 4, 2018

Dangers: Lack of authority on the YMYL website; weak EAT signal.

How it works: The Google Medic update appears to disproportionately affect medical and other websites dealing with potentially life-changing decisions (financial, legal, educational). Although not explicitly confirmed, Google representatives have indicated that the update implements some EAT (Expertise, Authority, and Trust) signals from the Quality Assessor’s Guidelines document.

How to Adjust: To date, there is no proven recovery strategy for Medic renewals. Some SEOs suggest hiring expert writers in their field to give credibility to your site, others claim that the solution is to build an entity for your brand.

But, when it comes to facts, the only reliable way to increase the authority of your website is to develop your backlink profile. An efficient approach is to use a backlink research tool, such as SEO SpyGlass, and borrow backlink ideas from your competitors.


This algorithm was released by Google on October 22, 2019

Dangers: Poorly written content; content is out of focus; lack of context.

How it works: This Google algorithm update uses natural language processing technology to better understand search queries, interpret text, identify entities, and relationships between entities. We’ve seen Panda, Hummingbird, and RankBrain updates move away from keywords, and the BERT update is the culmination of these efforts. This allows Google to understand more of the nuances in queries and search results.

How to Customize: Make sure your content is well written and that it relates to one another. Also use standard language.

Latest Google 2021 Algorithm

Currently, Google is always updating its algorithm so that the content presented on the SERP is of higher quality. Here are some of the latest Google algorithms in 2021 that you should know, especially for those of you who are SEO activists or website owners.

Core Update

This algorithm was updated on January 13, 2020. Google did not provide a specific explanation regarding this update. However, even so we recommend that you check the SERP for the keywords you are targeting. Once the update has occurred, you can check which competitors are moving up or down in rankings and try to make smart guesses about the factors that influenced it.

Featured Snippet Decluttered

This algorithm was updated on January 22, 2020. This algorithm has an impact on the rich snippet on SERPs. Because of this the SERP on Google will be tidier.

Page Experience

This algorithm is planned to be released in May 2021. This Page experience algorithm is related to User Experience or user experience when interacting with a website.

The goal is to make visitors feel comfortable when visiting the websites they click on in search results. If this can be maximized on your business website then of course this will be very profitable because it is likely that your website is prioritized by Google to be on the first page.

According to SEMrush there are several aspects that affect this Page Experience, here are the signals that are part of the Page Experience:

  • Core Web Vitals
  • Mobile Friendly
  • Safe Browsing
  • Mobile Popup Algorithm / no intrusive interstitials

Core Web Vitals consist of Largest Contentful Paint (LCP) to measure loading performance, First Input Delay (FID) to measure interactivity and Cumulative Layout Shift (CLS) to measure visual stability.


So, that was the discussion about the types of algorithms for SEO and the latest Google Algorithm in 2021. For this Page Experience Algorithm, make sure your website’s vital web core is good and pay attention to mobile friendly and security aspects.
