## Definition

A sentiment signal is a measurable indicator of the emotional tone of content about a brand — positive, neutral, or negative — used by AI systems to assess brand reputation and trustworthiness when generating characterizations of a brand.

## Why It Matters for AI Search

Sentiment signals aggregate across a brand's full citation footprint. A brand with predominantly positive community-generated content, favorable press coverage, and strong review ratings produces positive sentiment signals that AI systems incorporate into brand characterizations. Monitoring sentiment signals — not just citation frequency — provides a complete picture of how AI systems are characterizing a brand's reputation, not just its presence.
