Quick summary

Adding captions to a YouTube video in YouTube Studio takes just a few steps: select the video from the Subtitles section, enable auto-generated captions for your language, review and edit the caption timing, then publish. This process improves video accessibility and boosts SEO by making your content indexable by search engines.

Steps

Go to studio.youtube.com and click Subtitles in the left sidebar.
Click the video you want to add captions to from the list.
Select your language to enable auto-generated captions, set it as the default if needed, then click Confirm.

Click Publish to make the captions live on the video.

📌 Why this matters

Adding captions to YouTube videos is essential for accessibility, audience reach, and search visibility. YouTube's auto-generated captions in YouTube Studio allow creators to quickly enable subtitles in their chosen language without manual transcription. Accurate captions improve watch time by making content accessible to deaf or hard-of-hearing viewers and non-native speakers. Publishing captions also helps YouTube's algorithm index spoken content, directly boosting video SEO and discoverability.
