# YouTube

**Type:** organization / platform (video + search).

Noted as the **second-largest search site in the world** after Google. The author states that LLMs draw heavily from YouTube's content, making an active channel a critical component of [[concept-answer-engine-optimization]] — see [[claim-llms-prioritize-reddit-youtube]] and the tactic [[action-maintain-youtube]].

**Enrichment / canonical reference:** video platform and search surface frequently cited in AEO guidance because AI systems can draw on its **transcriptions, metadata, and associated web references** — i.e., the value isn't only the video but the machine-readable text around it.
