Video SEO and Metadata

Video SEO is the set of metadata signals beyond the title and thumbnail that help YouTube understand and surface a video. The most important correction to common belief is that YouTube states plainly that “tags play a minimal role in your video’s discovery,” so the effort belongs in the description, chapters, and a strong Titles choice, not in stuffing tags. This is the discoverability layer beneath Packaging and feeds the search ranking described in Discovery Surfaces.

Descriptions

The description should open with the most informative lines, because that is what viewers and the system see before “Show more.” YouTube advises identifying one or two main words and featuring them in both the title and description, sourcing them via the Research tab and the Google Ads Keyword Planner. Bullet lists use an asterisk, plus, or hyphen. A good description front-loads the value proposition and links to related Playlists and Series.

Video chapters

Chapters improve navigation and can lift Audience Retention by letting viewers find the part they want. The rules are specific: the first timestamp must start at 00:00, there must be at least three timestamps listed in ascending order, and the minimum chapter length is 10 seconds. Chapters are added as a timestamp list in the description, and manual chapters override automatic ones.

Tags and hashtags

  • Tags play a minimal role and are mainly useful for commonly misspelled terms; excessive tags violate the spam policy.
  • Hashtags categorize content: up to three of the most engaging hashtags display above the title, and adding more than 60 hashtags makes YouTube ignore every hashtag on that content. Hashtags must be directly related to the content.

How to apply

  • Put the keyword in the title, the first line of the description, and the chapter or section names; skip tag-stuffing.
  • Add chapters to any video long enough to have distinct sections.
  • Use one to three relevant hashtags, never a wall of them.
  • Validate the keyword against real demand before publishing; see Ideation and Inspiration.
