Quick Answer: Use review snippets and ratings markup only when the page displays a specific, verifiable review or rating that users can see on that exact local landing page. Mark up the entity being reviewed with the correct schema type, include only first-party or properly licensed reviews, and ensure the visible content matches the structured data exactly to avoid manual actions or rich-result suppression.
Correct implementation of review snippets and ratings markup on local landing pages starts with eligibility: Google requires that the rating or review be genuinely present on the page and tied to the specific business, product, or service represented there. For local pages, this usually means using the appropriate schema type for the page entity, pairing the structured data with visible review content, and avoiding aggregate ratings that are copied from elsewhere or applied sitewide. The markup must be precise, consistent, and not misleading; if the landing page is a city-specific service page, the reviews shown and marked up should reflect that exact location or service area, not a different branch or the corporate homepage.
