Content metric
Fact Density
Also: facts per 100 words, verifiable claim density
AI engines preferentially cite content with high fact density because each cited fact reduces the engines hallucination risk. The engine is more likely to quote a sentence that contains an unfalsifiable specific (price, dose, credential, location, time bound metric) than a sentence that contains a vague marketing claim.
Editorial discipline matters more than word count. A 600 word treatment page with 12 stated facts (pricing, frequency, dosage range, provider credentials, eligibility, safety screening, follow up cadence, expected outcomes, common side effects, exclusions, alternatives, booking path) outperforms a 2,400 word page restating the same 12 facts across padded prose.
Cited facts
- Embedding exact statistics in content increases AI visibility by 30 to 40 percent because verifiable data points reduce model hallucination risk (Surmado, 2026).
