This markup indicates the item’s type as a product and uses the “review” property to add the review’s details inside the product schema markup.
3. Add the Review Schema to Your Website
Copy your generated review schema and add it to the <head> section of the relevant pages.
If you prefer not to add schema manually use a plugin. For example, you can use the Schema Pro plugin if you have a WordPress website.
4. Test Your Review Schema
Schema.org’s Schema Markup validator checks your schema markup for errors.
To test your review schema, launch the tool and switch to the “Code snippet” tab. Input your review schema.
Then, click “Run test.”

The tool will display any structured data errors.

Google’s Rich Results Test tool helps you test whether Google’s crawlers can detect and understand your schema markup.
It also shows you what the markup can look like on search results pages.
Open the tool and click “Code.”
Paste your review schema. Choose a device type. Then, click “Test code.”

The tool then highlights the valid and invalid structured data items.

Click “Preview results” to preview your schema markup on Google SERPs:

5. Measure the Impact of Review Schema
Measure the impact of your review schema by tracking how many of your pages appear in search results as review snippets, and how those review snippets perform.
Semrush’s Organic Research tool makes this easy.
Open the tool and search for your domain.
Then, scroll down to “SERP Features.” Click “Reviews” under “Linking to domain.”
