Schema markup, also known as structured data markup, is a type of code that website owners can add to their HTML to provide search engines with additional information about the content on their webpages. Schema markup helps search engines better understand the context and meaning of the content, which can improve the display of search results and enhance the overall user experience. By using schema markup, website owners can specify details such as product information, business hours, event dates, reviews, and more, making it easier for search engines to display relevant and informative rich snippets in search results.

Implementing schema markup involves adding specific schema.org vocabulary to HTML tags on a webpage, such as <script> and <meta>, to define the structured data elements. This can be done manually by adding schema markup directly to the HTML code or using tools and plugins that generate schema markup automatically.

Once implemented, search engines like Google can use the structured data to display rich snippets, which are enhanced search results that may include additional information, such as star ratings, prices, and availability, directly in the search results. Rich snippets can improve the visibility and click-through rates of webpages in search results, as they provide users with more information and context about the content before clicking through to the website.
