The timestamp rules
Chapters come from timestamps in the video description. YouTube looks for a list where the first timestamp is 0:00, there are at least three timestamps in ascending order, and each chapter lasts at least 10 seconds.
Put each timestamp at the start of its own line, followed by a short title: "0:00 Intro", "1:12 Unboxing", "4:30 Sound test". Save the description and the chapters appear on the progress bar.
- First timestamp is 0:00
- At least three timestamps
- Each chapter at least 10 seconds long
Name chapters like mini titles
A chapter title is a promise for that section. "Sound test" is clearer than "Part 3". Use the words a viewer would search for, because chapter titles can show up in search results as key moments.
Fix your back catalog first
Adding chapters to videos that are already public is one of the quickest wins for a small channel. The mini-audit flags recent uploads without chapters, and the paid audit scores chapters alongside titles, descriptions, and tags.
Questions
Why are my YouTube chapters not showing?
Check that the first timestamp is 0:00, there are at least three, they are in ascending order, and each chapter is at least 10 seconds long. YouTube can also turn off automatic chapters for a video in Studio settings.
Do chapters help YouTube SEO?
Chapters make a long video easier to navigate and can appear as key moments in search. They do not replace a clear title and description.
Does Creator Climb add chapters for me?
The audit flags videos without chapters and drafts description improvements. You add the timestamps, since only you know where each section starts.
