# Review Schema

> Review schema is a schema.

*Technical implementation* · *Structured Data*

## Definition

Review schema is a schema.org structured data type for marking up product or service reviews — enabling star ratings to appear in rich results and providing structured social proof signals to AI systems. It is implemented using the Review or AggregateRating schema types.

## Why It Matters for AI Search

Review schema converts user-generated review data into machine-readable entity signals. Star ratings in rich results increase click-through rates for pages that earn them, and the structured review data feeds AI systems' understanding of a brand's reputation and customer experience signals. For businesses whose AI brand representation includes characterizations of customer satisfaction, correctly implemented review schema strengthens the structured evidence layer beneath those characterizations.
