Google uses algorithms to rank pages displayed in search results when users search.
This article discusses the history of Google’s algorithms and their impact on search results.
What is Google’s Algorithm?
Google’s Algorithm is the program used to determine the ranking of your search results.
When a user searches, Google picks up web pages that match the keyword from the vast amount of indexed data, ranks them using an algorithm and displays them.
It has been announced that there are over 200 factors that algorithms use to determine search rankings.
Algorithm elements are said to be the content and amount of content, frequency of site updates, page display speed, and number and quality of backlinks, but not all elements are made public.
Also, it is not open to what factors affect search rankings.
In the past, the accuracy of Google’s algorithm was not high, and superficial SEO techniques such as increasing the number of keywords on the page and increasing the number of backlinks were rampant.
As a result, low-quality sites with only advertisements and sites that are not related to keywords were often displayed at the top of search results.
To improve this situation and provide the best display for users who search, Google has continued to update its algorithm.
In many years, there are more than 500 algorithm updates.
Algorithm updates make changes to the rules for ranking search results.
When an update is made, it is necessary to make it an appropriate homepage in line with the new rules, but it will be difficult to accurately grasp the details of the update because some information will not be made public.
As a result, things that have been evaluated so far may no longer be evaluated, and SEO measures that have been approved may be subject to penalties, resulting in a significant drop in ranking.
Major changes to the algorithm that have been made so far include “Panda Update”, “Penguin Update”, and “RankBrain”.
Explore the best search results Google is aiming for by examining these big updates.

Major Google Algorithm Updates
What is Panda Update ?
Panda Update is a new Google Algorithm Update.
The panda update was aimed at lowering the evaluation of low-quality web pages that are of no value to users who searched.
The background to the introduction of the Panda update was that low-quality web pages were displayed at the top.
Many websites and pages were highly rated for factors unrelated to content, such as websites with a large number of pages containing keywords, and domain age length.
Displaying such search results will also reduce the value of Google’s search engine.
Therefore, Google implemented a panda update to exclude sites with thin and low-quality content from search results.
As a result, low-quality sites were significantly lowered in ranking, and content that was useful to users and content with high originality and expertise began to be displayed at the top.
By the way, it’s called a panda update because it’s an update that makes a clear distinction between high-quality websites and low-quality websites.
As of 2012, when the Panda update was introduced, the algorithm was manually updated and announced each time.
From March 2013, updates will be automated as a normal algorithm and will not be announced even if updates are made.
Therefore, it is important to regularly check search rankings and access numbers, and take necessary measures immediately if there is an extreme change.
In order not to be evaluated as a low-quality site in Panda Update, the points are highly specialized and unique content, the number of advertisements that do not interfere with the content, content that does not overlap with other sites or pages, and sharing on SNS. will be
What is Penguin Update?
The Penguin Update was a major algorithm update in April 2012.
The Penguin update aims to downgrade web pages that are spammy or violate Google’s webmaster guidelines.
Like the panda, the name comes from the penguin, which is black and white.
The Panda update was mainly concerned with the quality of websites, but the Penguin update mainly gives low ratings to websites that intentionally manipulate search rankings or engage in malicious spamming.
The background to the penguin update was that websites with excessive SEO measures were displayed at the top of the search results.
The Penguin update was made to eliminate such websites and display high-quality websites with useful content for users.
Specifically, SEO spam that overstuffs keywords, a large number of low-quality backlinks, unnatural backlinks from the same IP address, backlinks with the same anchor text, etc. I’m here.
The Penguin update was further updated in 2013 and 2014 and announced each time, but since 2016 it has been integrated into the core algorithm and will not be announced even if it is updated like the Panda update.
To avoid getting a bad rating on the Penguin Update, it is important not to engage in SEO spamming as defined by the Google Webmaster Guidelines.
SEO spam targets are websites that use automatic content generation, pages without original content, unauthorized redirects, hidden text or links, and unauthorized duplication of content.
In addition, the guidelines define low-quality backlinks such as “low-quality directory or bookmark site links” and “links embedded in widgets distributed on various sites”.
If you think that an existing backlink is having a negative impact, you can exclude that link from being subject to the Penguin Update by performing “Disavow Link” in Google Search Console.
What is RankBrain?
Google has officially announced that “content” and “backlinks” are the most important factors in determining search rankings, and “RankBrain” is the next most important factor.
RankBrain is an AI-based search algorithm introduced by Google in 2015.
Google’s algorithms are typically coded by engineers to make changes and modifications to the program.
The program itself does not change itself. However, RankBrain uses machine learning to evolve itself to display the best search results.
What makes RankBrain unique is that even if it’s an ambiguous or spoken word, it guesses the intent of the search and displays the search results.
In the past, a search for “nearby curry” would result in web pages containing the keywords “nearby” and “curry” at the top.
However, currently, it reads the user’s search intent of “I’m looking for a nearby curry restaurant” and displays information about nearby curry restaurants in the search results.
As such, RankBrain’s job is to understand the search query entered by the user and display the search results the user desires.
RankBrain attempts to put users first, as announced in “10 Things Google Says”.
Therefore, it is important to provide more useful content for users who searched for SEO.
If you search for the keyword you want to be displayed at the top, you will be able to know the tendency of the web page displayed at the top.
See what kind of content a page has, and what the title and description say, and you’ll understand why it’s ranked so highly by RankBrain.
Highly original content and high relevance to search queries are important points for SEO measures.
What is Mobile First Index?
Mobile-first indexing, which started in March 2018, means that the criteria for evaluating sites by Google will be mobile rather than desktop.
Google has traditionally used PC pages as the criteria for evaluating sites.
These evaluation criteria are changed to mobile pages to determine search rankings.
Even if there are desktop and mobile pages, only mobile pages will be indexed.
The reason for mobile-first indexing is that with the increase in smartphone users, searches on mobile devices have increased.
In 2015, Google announced that the number of searches on smartphones exceeded the number of searches on computers.
Mobile-first indexing itself is not an algorithm update.
For this reason, “content”, “backlinks” and “RankBrain” are emphasized as before, but there are also points to be aware of when doing SEO.
First of all, it is important to support Google’s mobile friendly.
When viewing a web page on a smartphone, if the text is too small or the link elements are too close together to make it difficult to use, that alone will not give a high evaluation.
In the past, it was common to first create a site for PCs and then optimize it for smartphones.
Therefore, it was not uncommon for mobile pages to omit part of the content because the amount of information that can be displayed is small.
However, mobile-first indexing puts more emphasis on the quality and quantity of content on mobile pages.
Even for mobile sites, content that is highly original and highly relevant to search queries is as important as traditional desktop sites.
