YouTube captions and search: what still helps
Accurate captions improve accessibility and give YouTube text to index — how to add SRT/VTT without overclaiming “SEO hacks.”

YouTube does not rank videos because you stuffed keywords into captions. Accurate captions help viewers stay, help accessibility, and give the platform a transcript of what was said — which can surface your content for relevant searches.
Do this
- Upload accurate SRT or VTT (or burn in if that fits your format).
- Match spoken words — do not force unnatural keyword sentences.
- Fix auto-captions before publish; names and jargon matter.
- Use captions on Shorts too — silent autoplay is common.
