**Brand mention**: An occurrence of your brand name in an AI-generated answer. We count and attribute these per prompt and model.

**Brand variant**: Alternative spellings or forms of your brand (e.g., "Pierview," "Pierview AI"). Add variants so we capture all mentions.

**Citation**: A source URL or reference that an AI model includes in its answer. When AI links to a page, that's a citation. We track URLs and domains.

**Citation rate**: Percentage of responses that include at least one citation to your site. Formula: (Responses with your URL / Total Chats) × 100.

## M–P

**Model/platform**: The AI system being queried, e.g., ChatGPT, Perplexity, Claude. Results vary by model.

**Sentiment**: The tone of a brand mention: positive, neutral, or negative. Aggregated across responses.

**Source**: The domain or site behind a citation (e.g., g2.com, techcrunch.com). Sources roll up multiple URLs for strategy.

**Source gap**: A domain that AI frequently cites but where you don't yet appear. An opportunity for content or PR.
