The concept of Semantic Content

     Semantic Content has long been a topic of interest to many SEO professionals around the world. In particular, Semantic Keyword is essential for the Onpage SEO process. More specifically, if you have a Semantic Keyword in the article, then Google will better understand that article. In other words, Semantic Keyword increases Google’s trust in the article.

Introduction to Hummingbird Algorithm and Rank Brain

Hummingbird algorithm

enity, Truy xuất thông tin

Launched in 2013 to help Google better understand the meaning behind the words that users search online. From 2013-2015, Google has not promoted this algorithm. By 2016, RankBrain was born with the role of supporting Hummingbird. Thereby strongly influencing the search results rankings and promoting each other’s effectiveness.

Rank Brain Algorithm

Khoa học thông tin, entitiy

Rank Brain is the name of an AI system that helps analyze results to the top of Google. (use a lot of Content analysis better to understand the meaning and value of the article)

RankBrain was born to help analyze results to Top Google with the following tasks:

Understand the meaning of user queries

Measuring user satisfaction with search results

I take an example from the blog post “How to get high in Google ranking” (how to to rank high on Google) by Brian Dean. To help you better understand how Rank Brain works.

     The article “How to get high in Google ranking” initially went to the top when users searched for the keyword “How to get high” (how to create excitement). But after a few weeks, it disappeared from the top 100 because at first Google guessed that “How to get high in ranking Google” had the same meaning as “How to get high”.

     But then 1, 2 weeks of measuring user behavior when returning the above results. At that time, it began to connect information and data inside and outside the Website, thereby better understanding the content. Rank Brain understood that the two phrases had two different meanings, so they let “How to get high in ranking Google” fly out of the top 100.

  How to optimize the RankBrain algorithm?

The most common way to optimize Semantic Content is to start optimizing by Topic instead of a specific keyword for Content. That is, you must create Semantic Content, including many Semantic Keywords.

     In addition to optimizing so that you can insert the title keyword or the URL containing the main keyword into the Heading tag also in your article, what else will you do?

    When Google analyzes the entire Content on your Website, it will pick up every word inside your article. Then connect those words together to create the Content of the article you are writing.

     Suppose your article is optimized only by inserting the keyword “diet plan”. In that case, it will not be as effective as the article including the words “vegetarian”, “weight loss”, “exercise plan”, “diet recipe”,… Thus, Google will connect these words to determine what field you are talking about?

     Just like that, the article is no longer a keyword stuffing, but an optimization according to Semantic Keyword (semantic keywords).

   Preparation steps to create Semantic Content

Note: We do not teach you how to write great Content, but we will share effective content optimization techniques with you.


In this article, I believe I have brought you the necessary knowledge about Entity, including Concepts, efficiency, and the core foundations of Entity Building. Besides, how to implement Entity through Semantic Content, Humming Bird algorithm, and Rank Brain algorithm. Along with tools Ahrefs and Textrazor are also presented in detail.

In addition, I also share about the case study PBN seedsite Stream hub that you can watch and research to understand more about seedsite.

Hopefully, after reading the article, you will understand better what Entity is to deploy the technique correctly on the Website yourself. Remember that not everyone knows about Entity and more than 90% of websites in the world do not implement this technique correctly. So, if the remaining 10% understand and implement it properly, don’t you already have a huge advantage?

Good luck!
