Using structured data markup, also known as schema markup, can enhance search results by providing additional context and information about your content to search engines. By implementing structured data, you can highlight key elements like product details, reviews, events, recipes, and more in search engine results pages (SERPs). This can result in rich snippets, knowledge panels, and other enhanced search features that make your website stand out and attract more clicks from users. By structuring your data in a way that search engines understand, you improve the chances of your content being displayed prominently and increase its visibility in SERPs.
