How to use it
- Paste your title.
- Write a two-line summary. The first ~150 characters appear in search results and under the video before "more", so make them count.
- Add chapters, one per line, starting with
0:00. Three or more chapters with at least 10 seconds each turn on YouTube's chapter bar. - Add any links you mention and up to three hashtags.
Copy the result into Studio's description box.
Why chapters are worth the effort
Chapters let viewers jump to the part they need instead of leaving. They can also appear as "key moments" in Google search, which brings traffic from outside YouTube — useful for tutorials and explainers.
What not to put in a description
- Lists of unrelated keywords — YouTube treats that as spam.
- Dozens of hashtags — more than 60 and YouTube ignores all of them.
- Links to sites that break YouTube's policies.
Frequently asked questions
How long should a description be?
There's no fixed length. 150–300 words is plenty for most videos; what matters is that the first two lines are clear.
Do chapters help SEO?
They help viewers navigate and can appear in Google as key moments, which can bring extra traffic.
Can I reuse the same description on every video?
Keep a template for links, but write a fresh summary for each video.
