10 Best YouTube Keyword Tools to Increase Video Reach

Want to know which are the best YouTube keyword tools? 

In this article, we’ll go through free and paid tools that can help you find keywords for your content. We’ll also be telling you the pros and cons of the tools, and the types of users they’re best for.

By the end of the article, you’ll know exactly which YouTube keyword tool is the right one for you, and what you can use it for. 

Let’s get started.

What Are YouTube Keywords?

YouTube keywords are words that contextualize your videos to YouTube.

Video keywords help the platform understand what’s the kind of video you just uploaded, and who you made it for.

However, there are two ways to think of YouTube keywords

  • Video tags: This is the designated metadata area when uploading a new video to add keyword tags.
  • Video SEO: Treating keywords as search intent and context and incorporating target keywords into your video’s title, description, script, and more

The YouTube keyword tools we cover here will assist both uses.

Channel tags are used the same way to contextualize your channel as a whole. YouTube then uses those keywords to find other users that could be interested in your videos, and suggest it to them.

YouTube needs to use these keywords to make better sense of all of its videos, and have better success at keeping users engaged and on the platform.

Here’s where you can add keywords and how many keywords you should be aiming for:

Video Title1 Primary Keyword
Video DescriptionPrimary Keyword and as many variations as make sense
Video TagsUp to 500 total characters
Channel Tags5 to 10 focusing on broad channel topics

You should always focus on keywords with the right balance between relevancy and search volume to properly optimize your channel.

By using the right keywords, you can increase the chances of YouTube showing your content to the right person.

YouTube Keyword Research

So, using the right keywords is important. 

But, how do you know which keywords to use? 

That’s where our YouTube keyword tools come in.

YouTube keyword tools make keyword research easy by aiding you at every step of the way. They allow you to find related keywords and decide which keywords to prioritize based on the YouTube keyword volume, their competition, and other relevant information about them.

That way, you know you’re optimizing your content with data-driven decisions, instead of guessing.
