Nestlé 82% higher CTR on rich-results pages — Google's own documentation, attributed to one named company; RING-FENCED, never present as typical

Claim (verbatim from Google): "Nestlé has measured pages that show as rich results in search have an 82% higher click through rate than non-rich result pages."

Source: Google Search Central, "Intro to How Structured Data Markup Works," last updated 2025-12-10.

Confidence: Single-source — a single named company's self-measurement quoted by Google. Google does not link a fuller Nestlé case study from this line.

RING-FENCING DIRECTIVE: Use only as "one company reported." Never present as a typical or expected result. Never generalise to "structured data lifts CTR by 82%." See R4 — Do NOT generalise the Nestlé 82% CTR figure; it is one company's self-measurement, never present as typical.

Why this matters for Candid: This is the only "clean" CTR figure available — and it is exactly the figure most likely to get laundered into vendor sales decks as a universal multiplier. Quarantining its scope is editorial discipline. Pair with Google Search Central — structured data produces eligibility, not a guarantee; does not guarantee rich results even with correct markup — Google itself says structured data is not a ranking factor and even correct markup does not guarantee rich results.
