Review Schema is a type of structured data that allows you to mark up individual user reviews or aggregate ratings for a product, service, or organization. It uses the Review or AggregateRating types to specify details like the rating value, reviewer name, and the item being reviewed.
When implemented correctly, Review Schema can lead to the display of star ratings directly in your search result snippets. These visually appealing stars immediately draw attention, convey social proof, and significantly increase the trustworthiness and attractiveness of your listing in the SERP, leading to higher click-through rates.
Why it matters: For developers working on e-commerce sites, local business directories, or content platforms with user feedback, Review Schema is incredibly powerful. For example, if you have a product page with multiple customer reviews, you can use AggregateRating within your Product Schema to show the average star rating. This immediate visual feedback helps users quickly assess the quality and popularity of your offerings, making your search results stand out and encouraging more clicks.
