Check your YouTube title, description and tags against YouTube's character limits and best-practice sweet spots before publishing.

YouTube Title & Tags SEO Checker validates a video's title, description and tags against YouTube's published limits — 100 characters for titles, 5,000 for descriptions, and a shared 500-character budget across all tags — and flags practical best-practice sweet spots, like keeping titles under ~70 characters so they don't get clipped in search results.
