What Are YouTube Video Tags?
YouTube tags are hidden keywords that creators add when uploading videos via YouTube Studio. Unlike hashtags (visible above the video title), these meta tags are invisible to regular viewers. They help YouTube's algorithm understand the topic of your content and match it to relevant search queries. While titles and descriptions carry more SEO weight, tags still provide useful context - especially for niche topics, misspellings, and related content categorization. YouTube allows up to 500 characters of tags per video.
