Rich snippets are enhanced search results that display additional information beyond the standard title, URL, and meta description. Powered by structured data markup (such as Schema.org), rich snippets can include elements like ratings, reviews, event details, product information, and more. These visual enhancements help users quickly identify relevant content, improve click-through rates, and provide a more engaging search experience. Implementing rich snippets can give websites a competitive edge in search engine results pages (SERPs).
