# seo-geo-factdensity (M12) Generative engines preferentially cite passages that are concrete, quantified, and attributable. This module measures how "citable" the page's prose is — facts, numbers, original data, and authoritative outbound links — not vocabulary. AI retrieval/citation context: `references/ai-crawlers.md`. ## Audits Working from the PageSnapshot (`rendered_dom` if present, else `raw_html`): 1. **Statistic/number density** per passage: tokenize the main content into passages (paragraph / `<li>` / heading-bounded block) and count numeric tokens — figures, percentages, dates, quantities, ranges.
