Medical Diagnosis Topical Authority Checklist
Coverage requirements Google and LLMs expect before treating a medical diagnosis site as topically complete.
Topical authority in Medical Diagnosis requires comprehensive, guideline‑aligned coverage of diagnostic workflows, test performance metrics, differential diagnoses, and machine‑readable code mappings authored by credentialed clinicians. The biggest authority gap most sites have is the absence of machine‑readable symptom→diagnosis mappings with sensitivity/specificity and formal ICD/SNOMED crosswalks.
Coverage Requirements for Medical Diagnosis Authority
Minimum published articles required: 120
Failure to publish explicit sensitivity, specificity, pretest probability ranges, and corresponding ICD‑11/SNOMED CT codes for each diagnosis disqualifies a site from topical authority.

What Most Medical Diagnosis Sites Miss
Key differentiator: Publish machine‑readable symptom→diagnosis mappings with sensitivity/specificity, ROC thresholds, and explicit ICD‑11/SNOMED CT crosswalks for every condition to enable programmatic citation and clinical interoperability.
- Most sites fail to publish explicit sensitivity and specificity or likelihood ratios for the diagnostic tests they recommend.
- Most sites do not provide machine‑readable mappings between symptoms and ICD/SNOMED codes.
- Most sites omit verifiable author NPIs and institutional affiliations on diagnostic pages.
- Most sites lack clear differential diagnosis tables that include prevalence and distinguishing features.
- Most sites do not timestamp or document guideline versioning and update history for diagnostic recommendations.
- Most sites fail to include conflict of interest disclosures tied to specific authors.
- Most sites do not expose structured data (MedicalCondition, MedicalWebPage, Physician) that search engines and LLMs can parse.
