QUARANTINE — "Pages with structured data earn 35% higher CTR" / "2.5x higher chance of appearing in AI answers" / "40% more AI Overview appearances"
Summary
Quarantined claims:
- "Pages with structured data earn 35% higher CTR"
- "2.5x higher chance of appearing in AI answers"
- "40% more AI Overview appearances"
Reason for quarantine: From SEO agency/vendor blogs (Digital Applied, Stackmatix) with incentive to inflate, and no independent corroboration. The only clean primary CTR figure available is the Nestlé 82% — and that is single-company, RING-FENCED (Nestlé 82% higher CTR on rich-results pages — Google's own documentation, attributed to one named company; RING-FENCED, never present as typical, R4 — Do NOT generalise the Nestlé 82% CTR figure; it is one company's self-measurement, never present as typical).
Why we keep this note: These multipliers are circulating in SMB SEO sales decks. Internal discipline rule: any "Xx CTR uplift from structured data" claim that is not Google's own primary documentation gets quarantined. See R6 — Quarantine vendor CTR / AI-citation multipliers; the only clean primary figure (Nestlé 82%) is single-company and ring-fenced.
Source-incentive note: SEO agencies sell structured-data implementation — direct incentive to inflate CTR/AI multipliers.
