Rich snippets are enhanced search results that display additional information about a webpage, making it more visually appealing and informative. They often include elements like star ratings, images, or specific details such as product prices and availability. This extra information helps users quickly understand the content of a page before clicking on it. These snippets are generated using structured data markup, which webmasters can add to their HTML. By implementing this markup, websites can improve their visibility in search engines like Google and potentially increase click-through rates. Rich snippets can apply to various content types, including recipes, events, and products.
