Tags

Tags in video publishing are descriptive keyword labels added to a video's metadata when uploading to platforms like YouTube, Vimeo, or LinkedIn Video. They serve as explicit signals to the platform's search and recommendation algorithm about the video's topic, subject matter, and relevant keyword associations — supplementing the title, description, and auto-generated captions as signals used to determine when and to whom to surface the video. Tags work alongside the video's other metadata rather than replacing it: a video with accurate tags but a vague title and description will still underperform relative to one where all metadata elements work together to communicate topic relevance clearly.

On YouTube specifically, tags function as a keyword map: they should include the primary keyword the video targets, variations of that keyword (plural, related terms, common misspellings), secondary keywords that describe the video's broader topic, and occasionally the video creator's channel name or brand name. The YouTube algorithm uses tags to understand topical associations — a video tagged "video production tips" might be recommended alongside videos tagged "filmmaking," "content creation," and "camera settings" because those topics cluster together in the algorithm's topic model. Tags are not visible to viewers (though they appear in the page source) and have little direct SEO value for Google search, but they influence platform-internal discovery and recommendation.

For B2B content distribution, tags are one of many video metadata elements that collectively affect organic discoverability. The disciplined approach is to research the actual search terms potential viewers use — using YouTube's search suggestions, third-party tools like TubeBuddy or VidIQ, or Google Keyword Planner — rather than guessing or using generic terms that may have high competition. A video about "SaaS demo video best practices" should be tagged with specific terms potential viewers might type, such as "how to make a product demo video," "saas demo video," "software demo video production," and "b2b video marketing." Specificity and search intent relevance in tags produces better algorithmic signal than a large volume of generic tags that don't reflect what people actually search for.
