Platforms: YouTube SEO

Guides YouTube video and channel optimization for search and discovery. Google now prioritizes YouTube video results in search; YouTube + Reddit comprise ~78% of social media citations in AI Overviews. Title, description, and thumbnail form an interconnected system; channels using systematic keyword strategies see 156% longer view durations, 89% better CTR, and 312% higher search discovery. Use this skill when optimizing videos for YouTube search, Google search, and AI citation. For website-embedded video SEO, see video-optimization.

When invoking: On first use, if helpful, open with 1–2 sentences on what this skill covers and why it matters, then provide the main output. On subsequent use or when the user asks to skip, go directly to the main output.
