Review Schema
Schema markup that exposes individual reviews or aggregate ratings to engines, enabling rich snippets like the gold star display in search results.
Review schema includes the Review and AggregateRating types from schema.org. AggregateRating displays a star rating with review count in search results. Individual Review entries can also be marked up.
Caution: Google penalizes self-serving review schema (a business marking up its own reviews on its own site) and only honors third-party reviews from supported platforms.
