How to Add Chapters to a YouTube Video
Quick answer
Add a timestamp list to the video description, one per line, in the format 0:00 Intro. The first timestamp must be 0:00, you need at least three chapters, and each must be at least 10 seconds long. Save the description and YouTube segments the progress bar into labeled chapters automatically.
Step by step
- 1
Open the video's details in YouTube Studio
Go to Content, click the video, and edit the description field. You can add chapters to new uploads or existing videos.
- 2
List timestamps starting at 0:00
Format each line as timestamp then title, for example 0:00 Intro. The list must begin at 0:00 or chapters will not activate.
- 3
Add at least three chapters of 10+ seconds
YouTube requires a minimum of three timestamps, each covering at least 10 seconds. Keep titles short and descriptive since they show on the seek bar.
- 4
Save and verify on the watch page
Reload the video and hover the progress bar. It should show segmented chapters with your titles; if not, recheck the format line by line.
Worth knowing
- YouTube can generate automatic chapters. Your manual description timestamps always override them, and you can disable auto chapters in the video's settings.
- Chapters must be in chronological order, and timestamps beyond the video length are ignored.
Doing this for a brand, not just an account?
Chapters make long-form video scannable, and for tutorial or product content they decide whether a viewer finds their answer or bounces at minute two.
Common questions
Why are my YouTube chapters not showing?
Almost always a format issue: the list does not start at exactly 0:00, there are fewer than three timestamps, or a chapter is shorter than 10 seconds. Fix the description formatting and the chapters appear on save.
Do chapters help SEO?
Yes. Google can show individual chapters as key moments in search results, letting people jump straight to the relevant section. Descriptive chapter titles also give YouTube more context about the video's content.
Can viewers on mobile see chapters?
Yes, chapters work on mobile, desktop, and TV apps. Mobile viewers see chapter titles while scrubbing and can open a full chapter list from the player.
Should I use auto chapters or write my own?
Write your own for anything strategic. Auto chapters save time but their titles are generic, while manual titles let you target search phrases and match how you actually structure the video.
