# 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. ## Initial Assessment **Project context:** Read root `contextus.md` when present and load only the modules relevant to this task. Without Contextus, use available project material or user-provided facts and ask for missing information; do not create a parallel context system.
