Review schema is structured data markup (JSON-LD format) that tells search engines how to interpret and display patient ratings and reviews from your website in search results. When implemented correctly, it enables rich snippets — the star ratings that appear directly under your listing in Google search — which increase click-through rates and provide social proof before a patient ever visits your site. For healthcare practices, review schema is one of the highest-impact structured data implementations available.
What Review Schema Looks Like in Search Results
Review Schema Types for Healthcare
The schema type you implement determines how Google categorizes and displays the review data. For healthcare practices, the correct types depend on what you’re reviewing:
JSON-LD Implementation Example
Google’s preferred format for structured data is JSON-LD, placed in the <head> of the page or using a plugin like Rank Math. Here’s a correct implementation for a dental practice:
{
"@context": "https://schema.org",
"@type": "Dentist",
"name": "Atlanta Dental Group",
"url": "https://atlantadentalgroup.com",
"telephone": "+1-404-555-0100",
"address": {
"@type": "PostalAddress",
"streetAddress": "1234 Medical Center Drive",
"addressLocality": "Atlanta",
"addressRegion": "GA",
"postalCode": "30303"
},
"aggregateRating": {
"@type": "AggregateRating",
"ratingValue": "4.9",
"reviewCount": "312",
"bestRating": "5",
"worstRating": "1"
}
}
