JSON-LD Examples
Product Rating
An aggregate rating for a product.
{
"@type": "AggregateRating",
"ratingValue": "4.6",
"bestRating": "5",
"ratingCount": "2841",
"reviewCount": "489"
}Common Mistakes
Using AggregateRating as a standalone type — it should be nested inside Product, LocalBusiness, etc.
Missing both ratingCount and reviewCount — at least one is required.
Complete Guide to AggregateRating Schema Markup
AggregateRating is almost always used as a nested object within Product, LocalBusiness, Course, or SoftwareApplication markup. It tells Google the overall rating and how many people contributed to it, enabling the star rating snippet in search results.
You must include ratingValue and at least one of ratingCount or reviewCount. The bestRating defaults to 5 if not specified.
