Step-by-Step: How to Add Timestamps to YouTube
Step 1Generate your timestamps
The easiest way to create YouTube timestamps is to use a generator. Paste your video transcript into StampMyVid, choose how frequently you want timestamps inserted, and click Generate. The tool outputs timestamps in exactly the format YouTube requires.
If you prefer to write timestamps manually, you'll need to watch your video and note the time whenever the topic or section changes.

Step 2Open YouTube Studio
Go to studio.youtube.com and sign in. In the left sidebar, click Content. Find the video you want to add timestamps to and click the pencil (edit) icon.

Step 3Add timestamps to the description
In the video description box, paste your timestamps. You can add them at the top, bottom, or after an intro paragraph — YouTube finds them wherever they appear in the description.
A valid timestamp block looks like this:

Step 4Save your changes
Click Save in the top right corner. YouTube processes the timestamps within a few minutes. Once done, you'll see a segmented chapter bar on your video's progress timeline.

YouTube Timestamp Format Requirements
YouTube is strict about timestamp format. Every requirement must be met or chapters won't activate:
| Requirement | Details |
|---|---|
| First timestamp | Must be exactly 0:00 |
| Minimum count | At least 3 timestamps required |
| Format | MM:SS or HH:MM:SS |
| Order | Must be ascending (earliest to latest) |
| Line format | Each timestamp on its own line, followed by a title |
| Video length | Video must be longer than the last timestamp |
Common Mistakes That Stop Chapters Working
Missing 0:00
The most common mistake. Every timestamp list must start with 0:00 or YouTube ignores the entire block.
Fewer Than 3 Timestamps
YouTube requires at least 3 timestamps. One or two will never activate chapters.
Wrong Format
Using 1.30 instead of 1:30, or including extra characters breaks the detection.
Out of Order
Timestamps must be in chronological order. Jumping backwards breaks the chapter system.
Why Adding Timestamps Helps Your YouTube SEO
Timestamps aren't just a viewer convenience — they're an SEO tool. When you add chapters to a YouTube video:
- Google indexes each chapter as a separate content snippet that can appear in search results
- Your video can rank for multiple keywords — one per chapter title
- Chapter snippets sometimes appear in Google search results with a direct timestamp link, driving more clicks
- Higher average view duration (from better navigation) signals quality to YouTube's algorithm
- Chapters appear in YouTube search results as a list, giving your video more visual space in results
