How to Add Keywords to YouTube Video Descriptions: 12 Tips

YouTube descriptions give creators an opportunity to explain their videos, provide useful resources, and give viewers more information about the content. They can also help YouTube and viewers understand what a video is about when relevant keywords are used naturally.

However, adding keywords does not mean repeating the same phrase again and again. Effective YouTube descriptions should be useful, readable, and closely related to the actual video.

If you want to learn how to add keywords to YouTube video descriptions, this guide explains where to place keywords, how to use related terms, and which common mistakes you should avoid.

1. Understand Your Main Keyword

Before writing your description, identify the main phrase that represents your video’s topic.

For example, if your video teaches viewers how to create YouTube thumbnails, your main keyword could be:

how to make YouTube thumbnails

Your description should naturally explain that topic rather than trying to insert the keyword into every sentence.

Think about what someone would type into YouTube when looking for your video.

2. Add Your Main Keyword Near the Beginning

One practical approach is to mention your primary keyword naturally within the opening sentences.

For example:

In this guide, you’ll learn how to make YouTube thumbnails that are clear, attractive, and easy to understand on mobile devices.

The keyword fits naturally into the sentence and immediately tells viewers what the video is about.

Avoid awkward sentences created only to include a keyword.

3. Write a Useful Video Summary

After introducing the main topic, explain what viewers will learn from the video.

For example:

This tutorial covers thumbnail layout, text size, image selection, contrast, and common design mistakes that can make thumbnails difficult to understand.

This gives you opportunities to include related phrases naturally while making the description useful to viewers.

4. Use Related Keywords

You don’t have to use only one keyword.

Add closely related terms that describe different parts of your video.

For a YouTube thumbnail video, related keywords could include:

• YouTube thumbnail design
• thumbnail tips
• video thumbnail ideas
• YouTube thumbnail size
• thumbnail optimization
• clickable thumbnails

Use these phrases where they genuinely fit the content.

The goal is to create a description that explains the topic comprehensively rather than a list of keywords.

5. Match Keywords With Search Intent

Keywords work best when they match what viewers actually want.

For example, someone searching for:

probably wants a practical tutorial.

Your description should therefore mention things such as keyword placement, description structure, related keywords, and common mistakes.

If the description talks about unrelated subjects, it can create a poor experience for viewers.

6. Use Keywords in Natural Sentences

One of the biggest mistakes creators make is keyword stuffing.

Instead of writing:

YouTube keywords, YouTube SEO, YouTube description keywords, YouTube keywords tips, YouTube SEO keywords…

Write naturally:

The second version is much easier for people to understand.

7. Include Keywords in Relevant Sections

Longer descriptions can contain several sections.

For example:

What You’ll Learn

• How to choose a main keyword
• Where to place keywords
• How to use related terms
• How to avoid keyword stuffing

This structure makes your description easier to scan and gives you natural opportunities to mention important topics.

Don’t force keywords into headings if they don’t make sense.

8. Add Keywords to Your Video Context

Your description should provide context around the video.

Explain what problem the video solves, who it is for, and what viewers can expect.

For example:

This beginner-friendly YouTube SEO tutorial explains how creators can organize their video descriptions, use relevant search terms, and provide useful information for viewers.

This naturally includes several topic-related concepts without turning the description into a keyword list.

9. Don’t Ignore Related Questions

Think about questions your audience may have about the topic.

For example, a description about YouTube keywords might naturally mention:

• Where should YouTube keywords be placed?
• How many keywords should you use?
• Should keywords be repeated?
• What are related keywords?
• How can beginners optimize descriptions?

You don’t need to answer every question in the description, but mentioning relevant questions can help explain the video’s purpose.

10. Add Useful Links After the Main Description

Your important keyword-focused content should not be buried under a huge collection of links.

Start with your video summary and useful information first.

Then add relevant resources such as:

• Your website
• Related videos
• Helpful articles
• Social media profiles
• Other resources

Keep the links relevant to the video’s subject.

11. Create a Reusable Keyword Structure

If you upload videos regularly, create a simple description format.

For example:

Video Summary:
Explain the topic and naturally include the primary keyword.

What You’ll Learn:
List the main points covered in the video.

Related Topics:
Mention closely related concepts naturally.

Useful Resources:
Add relevant links.

Timestamps:
Add chapters when appropriate.

Call to Action:
Tell viewers what to do next.

This can save time while allowing you to customize every description for its specific video.

12. Review Your Description Before Publishing

Always read your description once before publishing.

Ask yourself:

• Does the main keyword appear naturally?
• Does the description accurately describe the video?
• Are related keywords relevant?
• Is the text easy to read?
• Did I repeat the same keyword too many times?
• Are the links useful?
• Does the description provide value to viewers?

If the description sounds unnatural when you read it aloud, simplify it.

How Many Keywords Should You Add?

There is no need to create an extremely long list of keywords.

Focus on one primary topic and a reasonable number of closely related terms that genuinely describe the video.

Quality is more important than filling the description with search phrases.

For example, a video about YouTube descriptions might naturally mention terms such as “YouTube SEO,” “video descriptions,” “keyword placement,” and “related keywords.”

You should not repeat every variation of the same phrase.

Common Keyword Mistakes to Avoid

Avoid copying a large keyword list into your description. This makes the content difficult to read and can make it look unnatural.

Also avoid using keywords that have nothing to do with your video simply because you think they may attract more searches.

Other common mistakes include:

• Repeating the same keyword excessively
• Using unrelated search terms
• Writing descriptions only for search engines
• Making misleading claims
• Copying exactly the same description for every video
• Adding too many unnecessary links

Your description should always accurately represent the video.

Final Thoughts

Learning how to add keywords to YouTube video descriptions is mainly about using relevant search terms naturally within useful content. Start with one primary keyword, mention it naturally near the beginning, add closely related phrases where appropriate, and explain clearly what viewers will learn.

Don’t focus on keyword quantity. Instead, create descriptions that are useful, readable, and closely connected to the video’s actual topic.

A well-structured description can complement your title, thumbnail, video content, and broader YouTube SEO strategy while giving viewers useful information before and after they watch.
