Rich-results CTR lift — Rotten Tomatoes +25%, Rakuten 2.7x traffic (Google-published)

Claim: Google's own documentation cites:

• Rotten Tomatoes: +25% higher click-through rate for pages enhanced with structured data.
• Rakuten: 2.7x traffic lift from structured-data adoption.

Source: Google Search Central documentation (Google-published).

Caveat: Google-published, self-selected (winners). Independent magnitude data is thin.

Confidence: Industry-consensus / Single-source.

Why this matters for Candid: Schema is NOT a ranking factor (Schema/structured data — NOT a ranking factor; eligibility for rich results) — but rich-result eligibility CAN lift CTR meaningfully when the page qualifies. Implement the relevant ~30 supported types (LocalBusiness, Product, Review, FAQ, Article) and stop. Don't treat schema as a competitive lever; treat it as eligibility infrastructure.
