Explanation: The recommended format for adding structured data to pages is JSON-LD. JSON-LD, which stands for JavaScript Object Notation for Linked Data, is a lightweight data-interchange format that is easy for humans to read and write and easy for machines to parse and generate. It is a preferred format for structured data markup because it allows web developers to embed structured data directly into HTML documents using a simple script tag, making it accessible to search engines and other applications that consume structured data. JSON-LD provides a clear separation between the HTML content of a webpage and the structured data, enhancing the maintainability and readability of the code. Additionally, JSON-LD supports a wide range of schemas and vocabularies, including those recommended by Schema.org, which cover various types of content such as products, events, organizations, and more. This flexibility allows web developers to easily markup different types of content on their pages, providing search engines with valuable context and information about the content, which can improve visibility and relevance in search results. Therefore, JSON-LD is the recommended format for adding structured data to pages due to its simplicity, flexibility, and compatibility with search engine guidelines and best practices.
