Review and AggregateRating JSON-LD Template

What this describes

Use Review for an identifiable evaluation and AggregateRating for a summary calculated from multiple ratings. Attach both to the exact item being reviewed. The example uses a product; choose another supported item type only when the page and review actually concern that entity.

Customize it

• Identify the reviewed item precisely and keep its name visible.
• Preserve the real scale; do not silently convert ratings to five stars.
• Use ratingCount for all ratings and reviewCount for written reviews.
• Keep the displayed summary synchronized with the underlying review system.
• Do not mark up ratings that users cannot find. For Google’s star review feature, a business’s own site is ineligible when it controls reviews about itself and marks up that LocalBusiness or another Organization, including through an embedded third-party widget. This restriction does not turn every product review into a self-serving review.

Validate it

Recalculate the aggregate from the source system, then use the live-page JSON-LD validation tutorial and Schema.org Validator. When targeting Google review snippets, also use the Rich Results Test and review current eligible item types and policy restrictions.
