YouTube動画にチャプターを追加する方法

Adding chapters to your YouTube video is not just about structure — it’s a powerful tool to enhance user experience and increase your video’s visibility in search results. Chapters let viewers skip directly to content they care about most, improving retention and engagement.

But to truly maximize performance, your video must also have an optimized title — one that encourages clicks, ranks well on YouTube and Google, and aligns with audience intent. This guide will show you both: how to add chapters and how to optimize your title for CTR.

Using VOMO, you can automatically transcribe YouTube videos and generate chapters. If needed, it can also help fine-tune or edit them.

How to Manually Add Chapters on YouTube

Chapters are created using timestamps in your video description. Here’s the simple process:

1. Go to YouTube Studio → Content → Edit DescriptionChoose the video and click “Edit.”
2. Add timestamps in your video descriptionFormat example:00:00 Introduction01:15 Why Chapters Improve SEO03:40 Step-by-Step Setup06:00 Title Optimization Tips09:00 Final ThoughtsThe first timestamp must start with00:00for YouTube to recognize it.

How to Use Automatic Chapters on YouTube

YouTube’s AI can generate chapters automatically if you enable the option:

For creators focusing on optimization, manual chapter creation still performs best — it gives you full control over keyword placement and viewer flow.
