## Definition

User-generated content (UGC) is content created by users on platforms such as Reddit, YouTube, review sites, and social media — including reviews, forum posts, videos, and community discussions. AI systems frequently index and cite UGC as evidence of real-world brand experience and community consensus.

## Why It Matters for AI Search

UGC is among the most influential content types in AI search for consumer-facing brands. When AI systems answer questions about brand reputation, product quality, or customer experience, they frequently draw from UGC — particularly Reddit threads, YouTube reviews, and platform-specific review content. For brands managing their AI representation, monitoring and influencing UGC is as strategically important as managing owned content.
