Why YouTube descriptions matter
Your description helps YouTube understand what your video is about, which affects where it shows up in search and suggested videos. It also gives viewers the context, links and chapters they need to get the most out of your content.
Our free YouTube description generator writes descriptions that serve both: a keyword-rich opening, a clear summary, optional chapters and a call to action.
The anatomy of a great YouTube description
- Opening lines (about 150 characters): a summary with your main keyword. This is what shows in search results and above "…more".
- Summary: one to three short paragraphs about what viewers will learn or see, using related keywords naturally.
- Chapters: timestamps starting at 0:00 that split your video into sections viewers can jump to.
- Links: your website, related videos, playlists, products and social profiles.
- Call to action: ask viewers to subscribe, comment or watch another video.
- Hashtags: up to three relevant hashtags, which appear above your title.
How long should a YouTube description be?
YouTube descriptions can be up to 5,000 characters. You don't need to use them all, but a few hundred words gives YouTube more context and gives viewers useful information. Just make sure the first two lines work on their own.
| Part | Guideline |
|---|---|
| Maximum length | 5,000 characters |
| Visible before "…more" | About the first 150 characters |
| Chapters | Start at 0:00, at least 3 chapters, each 10+ seconds |
| Hashtags | First 3 show above the title; never more than 15 |
Adding chapters to your video
Chapters make longer videos easier to navigate and can appear in Google search results. To create them, list timestamps in your description, starting with 0:00. YouTube requires at least three chapters, each at least 10 seconds long. The generator suggests chapter titles based on your topic; update the times to match your edit.
