ClaimReview Schema: Fact-Check Rich Results and AI Verdict Citation
ClaimReview schema marks fact-checking articles with machine-readable verdict labels - True, False, Mostly True, Satire. When Google's AI systems generate answers about contested factual claims, they query the Fact Check Explorer database (which indexes ClaimReview schema) to surface verified verdicts. For fact-checking organizations, ClaimReview creates a direct AI citation pathway for claim-related queries.
For medical YMYL context, see Medical Schema and E-E-A-T for AI.
Google supports any textual rating label - these are the most widely recognized IFCN-aligned labels. The ratingValue (1-5 scale) in schema maps to these labels for machine readability.
