Review Schema

Structured data that marks up customer reviews and ratings so they can appear as star ratings in search results. Two related types do the work: Review markup for individual reviews and AggregateRating for the summary — the ★4.7 (312) that renders under your listing. Those stars are among the most powerful click-through assets on the results page: in a column of interchangeable blue links, the listing with a visible rating reads as pre-vetted by other buyers, and it takes the click from higher-ranked competitors more often than most site owners expect. The rules are stricter here than for most schema types, because review markup was abused for years. The reviews must be real, collected by you, and visible on the page that carries the markup. Self-serving review markup — an organization marking up reviews about itself on its own homepage — is explicitly ineligible for stars. Ratings must come from actual customers, not be invented, hardcoded, or pulled from a third-party widget that never displays on the page. Violations don't just fail to earn stars; they can draw a manual action that strips rich results across the entire site. What we find on stores: review plugins outputting AggregateRating on pages with zero visible reviews, star values hardcoded into themes by a past developer, markup left behind on products whose reviews were deleted, and counts that disagree with what the page actually shows. Our team ties the markup to your genuine review data and keeps it inside Google's guidelines — stars you earn and keep.
