Google documentation — structured data makes pages ELIGIBLE for rich results, NOT a generic ranking boost ("enables a feature to be present, does not guarantee that it will be present")

Summary

Claim (verbatim from Google): "Using structured data enables a feature to be present, it does not guarantee that it will be present." Structured data confers rich-result eligibility, not ranking.

Source: developers.google.com/search/docs/appearance/structured-data/sd-policies — current.

Confidence: Verified (primary documentation).

Why this matters for Candid: Direct refutation of the widespread vendor claim that "schema markup boosts rankings." Anchors R2 — Schema markup is rich-result ELIGIBILITY, not a ranking boost; stop claiming otherwise in client materials and pairs with John Mueller (Google) via Search Engine Journal — "There's no generic ranking boost for SD usage".
