About this tool
Review markup, and the rules behind the stars
Review markup describes one review of one specific thing: a product, a book, a film, a course, a restaurant. Google shows review stars only when the reviewer is a real person or publication and the review is not self-serving — a business marking up reviews of itself on its own site is not eligible. The generator checks the rating against its scale and flags generic reviewer names that Google ignores.

Rating on its scale
Set the scale (out of 5, 10 or 100) and the rating is checked against it.
Eligible or not
The self-serving rule and generic reviewer names are explained before you publish, not after.
Any reviewable type
Products, local businesses, software, books, films, courses, events, games, recipes and more.
Step by step
How to create review schema
Fill in the form
Required fields are marked with an asterisk; recommended ones say so. Leave anything you do not have blank — it is left out.
Fix what it flags
The checks under the code update as you type. Fix the red ones to be eligible for rich results.
Copy into your page
Paste the script tag into your page’s head (or add it through a tag manager), then confirm it in Google’s Rich Results Test.

Questions
Questions about this tool
Everything here runs in your browser — nothing you add is uploaded. More in the general FAQ.
What is schema markup?
Structured data in a standard vocabulary (schema.org) that describes what a page is about in a form machines can read without guessing — a business and its hours, a product and its price, a list of questions and answers. Google uses it for rich results, and AI search engines use it to understand and cite pages.
Where do I put JSON-LD on my page?
Paste the whole <script type="application/ld+json"> block into the page’s <head>, or anywhere in the <body>. Google reads it in either place. In WordPress, Webflow or Shopify, use the page’s custom code field, or add it through Google Tag Manager.
Does schema markup improve rankings?
Not directly. It makes a page eligible for rich results — stars, prices, breadcrumbs — which tend to earn more clicks, and it helps search engines and AI assistants understand the page correctly.
How do I test my structured data?
Use Google’s Rich Results Test to see which rich results a page qualifies for, and the Schema Markup Validator at validator.schema.org for general schema.org errors. After publishing, Search Console reports any problems it finds across the site.
Is anything I type stored?
No. The markup is generated in your browser as you type, and nothing is sent anywhere or saved.
