Review schema JSON-LD generator
Build valid Review structured data in seconds. Fill in the fields, copy the block, paste it into your page.
Describes a single review: what was reviewed, who reviewed it and the rating they gave. Use it for editorial reviews and genuine customer reviews shown on the page.
Your JSON-LD
<script type="application/ld+json">
{
"@context": "https://schema.org",
"@type": "Review"
}
</script>Still needed: Item name, Rating, Reviewer name.
Adding Review JSON-LD to your site
JSON-LD sits in a <script type="application/ld+json"> tag and describes the page in the shared schema.org vocabulary. Search engines and AI answer engines read it to understand entities and relationships without guessing from layout. The markup must match what visitors can actually see on the page.
For the full picture — which types to add first, and how AI engines use them — read the structured data guide. To see whether the rest of your site is readable by AI crawlers, run the AI bot checker or a full audit, which flags pages missing structured data.

Questions, answered
Which fields does a Review need?+
Google’s review snippet needs the item reviewed, a rating (reviewRating) and an author. Include bestRating and worstRating whenever your scale is not the default 1–5.
Can I review my own business with Review schema?+
You can, but Google does not show review rich results for self-serving reviews of your own LocalBusiness or Organization. Use Review for third-party items and genuine customer reviews of products.
What is JSON-LD?+
JSON-LD (JavaScript Object Notation for Linked Data) is the format Google recommends for structured data. You put a small block of JSON in a script tag, using schema.org types, to tell search engines and AI answer engines exactly what a page is about — an article, a product, a business, an FAQ.
What is the difference between JSON-LD and JSON?+
JSON-LD is JSON with a few reserved keywords (@context, @type, @id) that tie the data to a shared vocabulary such as schema.org. Every JSON-LD document is valid JSON, but plain JSON has no @context, so a crawler cannot tell what your keys mean. The @context and @type lines are what turn your data into structured data.
Where do I put the JSON-LD code?+
Inside a <script type="application/ld+json"> tag, in either the <head> or the <body> of the page it describes. Google reads both. In a framework, render it server-side so crawlers get it without running JavaScript.
