10 Google Algorithms You Must Understand to Increase Rankings

Google is currently the smartest search engine, but it continues to improve its algorithms for development. An SEO professional who wants to achieve good results must understand Google’s algorithms. This knowledge helps avoid mistakes and follow Google’s principles, ensuring that the SEO process is as effective as possible. In this article, we will discuss the core algorithms that every SEO practitioner should know when optimizing a website..

1. What is Google’s Algorithm?

1.1 Concept

Google’s algorithm is a common term for SEO professionals when optimizing a website. To better understand it, you need to grasp the concept of “algorithm” before analyzing the details. An algorithm is a finite set of clear instructions that solve a problem.

Simply put, Google’s algorithm is a set of algorithms and strict rules that help Google process data. The way the algorithm works ensures that Google selects results and ranks search results on websites.

1.2 Input and Output

When searching, the most basic input is the Google Index, and the output is the search engine results page (SERP). People often think of a website’s information as input, while search results are the output. In reality, the process by which Google collects data and returns results when users search is quite complex.

The Index is called Google’s index and is a collection of information sorted alphabetically. Similarly, Google Index is the process of categorizing and organizing data from websites. Local data, social networks, and other data sets are part of Google’s databases.

These data are divided into different data centers. Through the search engine, you get the output as the results page (SERP). In SEO, SERP is an important factor that determines website ranking. To provide the most relevant content for users, SEO algorithms must be continuously updated.

1.3 Ranking and Relevance

For a website to rank high on search pages, SEO professionals must optimize SEO according to Google’s search algorithm. To do this, you need to focus on two basic steps: relevance and ranking. These are fundamental principles that help your website get evaluated and ranked highly.

In the first step, Google selects pages that contain content relevant to the search results and ranks them in order. Second, ranking is a necessary condition for the algorithm’s operation. A website’s ranking, whether high or low, depends on Google’s ranking criteria.

1.4 Penalties and Disavow

As an SEO professional, you must follow Google’s guidelines for website management. For example, Google applies manual penalties to low-quality websites. To avoid penalties from Google, you can check your website through Google Webmaster Tools.

Similarly, Disavow – full name Google Disavow Backlink – is a tool managed by webmasters. In SEO, backlink management is very important as it can affect your website’s ranking on the search page. The Disavow tool helps webmasters block black links and remove penalties from the algorithm.

2. Why Do You Need to Understand Google’s Algorithm in SEO?

2.1 Google’s Algorithm for SEO

For SEO professionals, it is essential to continuously update information related to SEO algorithms. Every 2 to 3 months, Google’s algorithm changes frequently, often introducing new penalties. Understanding the rules of the algorithm will help you run your website effectively and provide the best experience for your customers.

In some cases, many “black-hat” SEOs still use tricks to avoid penalties from Google and improve rankings. Keyword abuse by SEO professionals will affect a website’s ranking. However, since the algorithm is continuously updated, instead of trying to “game the system,” you should study the algorithm carefully to avoid serious penalties from Google.

2.2 Google’s Algorithm in Search

For content creators, understanding the operating principles of a search engine makes their work smoother. Google is the primary search engine used to retrieve data from search queries. Google’s search algorithm is one of the algorithms that helps users find keywords quickly and accurately.

Google’s search algorithm is continuously upgraded based on user needs. Depending on various factors, Google provides search results that match individual desires. If you understand Google’s search engine principles, your SEO efforts will achieve the highest quality results.
