The YouTube SEO Checklist: Titles, Descriptions, Tags and Chapters

Titles: one promise, one keyword

Keep titles under 60 characters so they survive mobile truncation. Lead with the outcome and include the primary keyword naturally.

Descriptions: the first two lines do the work

The first 150 characters appear in search results. Restate the promise, then use the body for timestamps, links and context.

Chapters and tags

Chapters improve retention by letting viewers jump to value, and they surface as key moments in Google search.

Tags are a minor ranking factor but still help disambiguate niche or misspelled terms.
