Create Review JSON-LD with star ratings that can appear in Google results. Enter the item, review text, author, and rating.

What is the Review Schema Generator?

A review schema generator builds Review structured data in JSON-LD format that describes a review of a product, business, book, movie, or other item. It captures the reviewed item, the review text, the author, the date, and the star rating. When Google accepts the markup, your search listing can display gold star ratings — one of the most eye-catching enhancements available.

Star ratings work because they compress social proof into a glance. A listing showing 4.8 stars from 200 reviews instantly communicates trustworthiness in a way plain text cannot, and listings with stars consistently earn higher click-through rates than identical listings without them. For products and local businesses, this visual edge often decides which result gets the click.

Enter the item details and the review itself, generate the JSON-LD, and add it to the page containing the review. Google requires reviews to be genuine and visible on the page — never mark up reviews you invented.

Review markup sits at the intersection of SEO and reputation management. The stars it can produce amplify whatever reputation you have — excellent for beloved businesses, unforgiving for poor ones. Earn genuine positive reviews first; the markup merely broadcasts them.

How to use the Review Schema Generator

  1. Select the type of item being reviewed, such as Product or LocalBusiness.

  3. Paste or write the full review text and the reviewer’s name.
  4. Set the star rating from 1 to 5 and the date the review was written.
  5. Click Generate Review Schema and add the JSON-LD to the page displaying the review.

Review Schema Generator use cases

Ecommerce product reviews

Online stores can mark up customer reviews on product pages so star ratings appear in Google results and shopping listings. Products with visible ratings attract more clicks from comparison shoppers scanning the results page.

Local business testimonials

Service businesses can mark up genuine client reviews on testimonial pages. Star-enhanced listings in local searches build immediate credibility against competitors showing plain results, tipping close decisions. Authentic, detailed testimonials outperform generic praise in both rich results and human trust.

Editorial reviews

Publications reviewing books, movies, software, or gadgets can mark up their critic reviews. The rating stars distinguish professional reviews from regular content in search results, attracting readers seeking expert opinions.

Recipe and course ratings

Food bloggers and course creators can mark up user ratings on recipes and lessons. Star ratings in these niches strongly influence which result a searcher trusts enough to click, directly affecting traffic.

Tips

  • Only mark up real reviews that are visible on the page. Fabricated reviews violate Google’s guidelines and risk penalties.
  • Never mark up reviews of your own business that you wrote yourself — Google calls this self-serving and ignores it.
  • Include the worst reviews too. A perfect 5.0 from every reviewer looks suspicious to both Google and shoppers.
  • Keep the rating scale consistent. Mixing 5-star and 10-star scales across your site confuses the markup.

Frequently asked questions

What is review schema?
Review schema is structured data describing a review: the item reviewed, the review text, the author, the date, and the rating value. Valid markup makes the page eligible for review rich results, which display star ratings in Google search listings.
Will review schema guarantee star ratings in Google?
No. Valid markup makes you eligible, but Google decides whether to show stars based on the page's trustworthiness, the query, and its own quality checks. Genuine reviews on established pages earn stars most reliably over time. Pages with authentic, detailed reviews tend to earn the stars display faster than thin testimonial pages.
Can I add review markup for my own business?
You can mark up genuine third-party reviews displayed on your site, but reviews you write about your own business are considered self-serving and Google ignores them. The safest approach is marking up verified customer reviews from real buyers. Encourage real customers to leave reviews on your site or third-party platforms instead.
What is the difference between Review and AggregateRating?
Review describes a single review with its text and author, while AggregateRating summarizes many reviews as an average score and count. Product pages often use AggregateRating; testimonial or editorial pages use individual Review blocks for each write-up. Many strong pages use both: individual reviews for depth and an aggregate summary for the headline score.
What rating scale should I use?
The standard is 1 to 5, with bestRating 5 and worstRating 1. Google understands this scale universally. If your site uses a different scale, convert it or declare bestRating and worstRating explicitly in the markup to avoid confusion. Whatever scale you choose, apply it uniformly so your markup stays internally consistent.
Do the reviews need to be visible on the page?
Yes. Google requires marked-up reviews to be visible to users on the page. Hidden review markup is a guideline violation that can lead to loss of rich results or even a manual action against your site. Visible reviews also convert human readers, so the requirement aligns with good page design anyway.
Is this review schema generator free?
Yes — free and unlimited with no signup. Generate Review JSON-LD for genuine reviews across your site, processed entirely in your browser with valid output. Mark up authentic reviews site-wide with no accounts, limits, or fees. Genuine reviews deserve proper markup at no cost.
