Add Review schema markup
Star ratings in search results increase click-through rates by up to 35%; incorrect or missing schema means competitors with valid markup capture that visibility advantage.
Quick Reference
- Use
Review schema on individual review pages and AggregateRating on product/service pages to earn star-rating rich results
AggregateRating requires ratingValue, ratingCount or reviewCount, and valid bestRating / worstRating values- Ratings must reflect genuine user reviews — Google penalises self-serving or fabricated ratings
- Validate markup with Google's Rich Results Test before deploying
Check
Inspect the page source or rendered DOM for JSON-LD blocks containing "@type": "Review" or "@type": "AggregateRating". Verify required properties are present: ratingValue, ratingCount/reviewCount, bestRating. Run the URL through Google's Rich Results Test.
Fix
Add a JSON-LD <script> block with AggregateRating nested inside the main entity (Product, LocalBusiness, etc.). Populate ratingValue and ratingCount from real review data. Remove any schema on pages with no genuine user reviews.
Explain
Explain how Review and AggregateRating schema work, which page types are eligible for star-rating rich results in Google Search, and why fabricated ratings violate Google's structured data guidelines.
