Review Schema Generator

This free review schema generator builds valid Review and AggregateRating JSON-LD so Google can show star-rich snippets for your product or local business listing. Paste in the item name, the reviewer, the rating, and the review text, then copy the output straight into your page head or body. Star ratings in the search results lift click-through rates, and structured data is the only way to make those stars eligible to appear.

The review schema generator maps every field to the correct Schema.org property, including the nested itemReviewed object and the reviewReating value, and it lets you add optional AggregateRating numbers when you want to surface an overall score and review count. Everything runs in your browser, so nothing you type is sent anywhere. When the markup looks good, validate it with Google's Rich Results Test before you publish.

Structured data is one piece of a strong local presence. Once your snippets are live, track how your business ranks across the map with ProMapRanker, a Google Maps grid rank tracker you can start free.

FAQ

What is Review schema and why does it matter?

Review schema is structured data in JSON-LD format that describes a rating someone gave to a product, service, or business. When Google reads it, your page becomes eligible for star-rich snippets in search, which stand out and tend to earn more clicks than plain text results.

Do I need AggregateRating as well as Review?

Use a single Review when one person rated the item, and add AggregateRating when you want to show a combined score from many reviews along with the total review count. This generator lets you include both, so you can publish one Review while still displaying your overall average and how many ratings it is based on.

Where do I place the generated JSON-LD on my page?

Copy the script block and paste it into the HTML of the page that the review describes, ideally inside the head section or anywhere in the body. Keep the values in the markup matching the visible content on the page, since Google requires the structured data to reflect what real users actually see.
