In this context, to succeed on YouTube, it is imperative to find the keywords of a YouTube video that will contribute to the best possible ranking of it on the platform’s search engine.

For judicious selection of the YouTube keywords associated with a video, there are keyword generator tools that will prove particularly useful for identifying these phrases. Good YouTube keywords will generate high traffic and will result in higher ranking on the platform, more audience and more views.

To attract more visitors to your YouTube channel, being able to choose the best keywords is essential. This article aims to explain the major role that these keywords play in the SEO process and details the most efficient methods to find the right YouTube keywords and thus highlight the videos of your channel in the search results.

YouTube channel keywords: a key role for SEO

Before tackling the crucial question of how to select keywords on YouTube, it is essential to define what a YouTube keyword is and see why it is so important in SEO.

What is a YouTube keyword?

Like Google, YouTube bases its referencing system on different rules and it is scrupulous respect for these that will allow a video or a channel to rise to the top of the results pages on the platform.

To achieve this, a detailed knowledge of these rules and conscientious work on the selection of YouTube keywords will provide quality SEO and higher than that of competing videos or channels.

The SEO rules applied by YouTube are embodied in algorithms which, following a search request on the platform, automatically classify the content according to precise criteria. You should know that the content of these algorithms is not the subject of any communication to Internet users.

If YouTube’s SEO rules are well-kept secrets, the main principles governing its system for ranking videos between them are nevertheless well identified by professionals. Here are the ones to remember:

  • The choice of YouTube keywords used in the video title;
  • The YouTube keywords appearing in the description of the videos;
  • The length of the video descriptions;
  • The “consistency” of the YouTube channel.

Understanding how YouTube SEO works is essential but not sufficient to place your videos at the top of the platform’s search engine results. One of the keys to success on YouTube is knowing, how to find the right keywords and this process must be based on a perfectly mastered methodology.

The role of YouTube keywords in SEO

For the optimization of its YouTube channel, the good use of keywords is one of the fundamental data for the acquisition of additional traffic. Finding the right YouTube keywords is something that many inexperienced YouTubers overlook by focusing too much on their videos themselves and too little on the text content of the videos.

This error can be partly explained by the fact that YouTube is a video sharing platform. However, the robots they use to rank the results and reference each of the videos do not currently have the ability to decrypt this category of content.

In other words, the platform applies a referencing policy for its video content that is very similar to that of any text content, hence the need to select its keywords with the greatest attention. Without rigorous work to find the right YouTube keywords, a channel’s videos will be much less likely to be viewed by Internet users.

In the context of a keyword research, you should know that expressions called “long tail” will be preferred in comparison with short and simple keywords. These “long tail” keywords, which are similar to sets of words or short sentences, have the advantage of being “nested”. In fact, on the occasion of a request made by an Internet user, the video will experience less competition and will be likely to be viewed by a large audience.

The challenge is therefore very simple: finding the right YouTube keywords will help optimize the video and allow it to appear among the first results of a search on the platform.

The methods available to collect keywords

How do you select the best YouTube keywords? Finding the key words is not such an easy task as it seems and if, in the case of the first videos, the inspiration will undoubtedly be there, the work will prove more and more difficult as the channel is enriched with new content.

One of the major challenges in keyword research is to offer your videos the greatest possible visibility over time and in search engines. For easy identification of the most searched keywords on YouTube, there are different methods you need to know to find them, regardless of the subject and theme considered.


Brainstorming is arguably the most conventional method but also one of the most effective for finding YouTube keywords. For YouTubers fortunate enough to work in a team, this technique has the advantage of comparing ideas and allowing the analysis of identified keywords from several angles at the same time.

Brainstorming is, moreover, a completely free technique.

Automatic entry

Autocomplete is a technique little used by YouTubers in the context of their keyword research, but which deserves to be known. During a search on the platform, the Internet user sees search suggestions appear. It would be wrong to think that these YouTube keywords would be generated randomly.

Indeed, these keywords suggested by the platform are those that have been often searched before and, in fact, include the category of automatic suggestions.

This autofill technique is highly recommended to have a better understanding of what Internet users are looking for and especially what YouTube keywords they are using in their searches.

The methodology to follow when opting for automatic completion is to establish a list of YouTube keywords in line with the identity of the author or the brand of the channel. It is then necessary to confront the latter with the searches as well as the words suggested by the platform. It will then be easy to ensure that the keywords considered are the most likely to be searched by as many Internet users as possible.

Competitor analysis

Another way to better target the most searched keywords on YouTube is to simply watch what the competition is doing. One of the common mistakes in YouTube keyword research is thinking that words already used by a competitor can no longer be used, which is absolutely wrong.

If certain keywords generate more views and offer increased exposure on the platform, there is every reason to take advantage of them for your own YouTube channel.

In the event that the keywords used by the competition could not be easily spotted, you should know that there are certain applications that will identify these famous keywords themselves, like TubeBuddy for example.
