Schema is a specific type of structured data that is used to markup content on a website in a way that makes it more easily understood by search engines. Schema markup uses a standardized vocabulary of tags, which can be added to the HTML code of a webpage to provide additional information about the content of the page.

Schema markup can help search engines to better understand the content of a webpage and its context, which can improve the accuracy and relevance of search results for users. For example, schema markup can be used to provide additional information about a product, such as its price, availability, and user reviews. This information can then be displayed in search results as rich snippets or enhanced search results.

Schema markup can also be used to provide additional information about other types of content, such as articles, events, local businesses, and more. Overall, using schema markup on your website can improve your search engine visibility, increase click-through rates, and enhance the user experience.
