Google Search Central — structured data produces eligibility, not a guarantee; does not guarantee rich results even with correct markup
Created 2026-06-21
Summary
Claim: "Google does not guarantee that your structured data will show up in search results, even if your page is marked up correctly."
Source: Google Search Central, "Intro to How Structured Data Markup Works," last updated 2025-12-10.
Confidence: Verified — primary.
Why this matters for Candid: The honesty caveat we are obliged to carry every time we recommend structured data: it produces eligibility, not a guarantee. Anchors R6 — Quarantine vendor CTR / AI-citation multipliers; the only clean primary figure (Nestlé 82%) is single-company and ring-fenced — without this caveat, vendor CTR-uplift claims smuggle in a "ranking factor" assumption Google explicitly rejects.
