Structured data refers to information that is organized in a predefined format and is easily accessible. It follows a fixed schema, making it easier to collect, store, and process. Examples of structured data include tables in databases, where each field contains a specific data type such as numbers, text, or dates. Structured data is especially useful for computer systems because it can be easily searched, filtered, and analyzed. In web development, structured data is often used in the form of markup, such as JSON-LD, to provide search engines with additional information about a webpage's content, enhancing its display in search results (Rich Snippets).
