Review schema markup is structured data (JSON-LD) that tells Google your page contains a review or aggregate rating. When properly implemented, Google may display star ratings in search results, which can dramatically increase click-through rates.
A Single Review schema represents one individual review with a rating and review text. AggregateRating represents the overall rating of an item based on multiple reviews, showing the average rating value and the total number of ratings.
No, Google does not guarantee star ratings. However, using valid Review or AggregateRating schema significantly increases your chances. Google typically shows star ratings for pages with genuine, high-quality reviews that are relevant to search queries.
The most common rating scales are 1-5 stars and 1-10 points. Choose the scale that best matches your platform or industry standard. Just make sure to set the bestRating and worstRating values correctly.
