Review schema and AggregateRating schema are structured data types that tell Google about product and service reviews on your page - enabling the gold star rating display you see below search results. They work together: AggregateRating provides the summary score (4.7★ from 348 reviews) while individual Review entities provide the specific reviews from named authors. Both must be present for Google to display star ratings in standard SERPs - AggregateRating alone is no longer sufficient for rich result eligibility as of Google's 2023 review policy update.
Review schema also feeds AI answer systems - when AI systems answer "is [product] good for X use case?" or compare multiple products, they extract and reference review data from pages with properly implemented Review schema. The reviewBody text of individual reviews is used for AI sentiment synthesis, and the AggregateRating score appears in AI comparison tables. Implementing review schema is one of the few direct links between your structured data and your AI citation quality for purchase-intent queries.
Review Schema Patterns: Three Implementation Types
Google distinguishes between individual reviews, aggregate ratings, and nested review patterns - each with different rich result eligibility and different AEO implications. Click each type to see the complete JSON-LD and when to use it.
When to use
Use on individual product, service, or entity pages - each review is authored by a specific reviewer.
