What Is Review Schema?

Schema.org structured data vocabulary for marking up review content so search engines understand and display it.

Review schema refers to the Schema.org vocabulary used to mark up review content in a machine-readable format. When implemented correctly using JSON-LD, microdata, or RDFa, review schema enables search engines to understand review content and display it as rich snippets in search results.

Core Review Schema Types

### Review Represents a single customer review: 
{   "@type": "Review",   "author": { "@type": "Person", "name": "John Doe" },   "datePublished": "2026-02-15",   "reviewRating": {     "@type": "Rating",     "ratingValue": "5",     "bestRating": "5"   },   "reviewBody": "Excellent platform for collecting reviews." }

### AggregateRating Represents the average of all reviews: 

{   "@type": "AggregateRating",   "ratingValue": "4.7",   "reviewCount": "342",   "bestRating": "5",   "worstRating": "1" }

### ItemReviewed The entity being reviewed:

  • Product
