What Is Schema.org Structured Data (JSON-LD)?
Schema.org structured data in JSON-LD (JavaScript Object Notation for Linked Data) format is the industry-standard metadata vocabulary recommended by Google, Bing, Yahoo, and DuckDuckGo to understand page content and generate rich search snippets (such as Organization details, Breadcrumbs, FAQs, and Products).
Key Technical Features

- Code Prettification: Formats compact code into clean, indented structures for documentation and code reviews.
- Code Minification: Removes extraneous whitespace and line breaks to minimize payload delivery size over HTTP.
- Cross-Format Translation: Converts seamlessly between JSON, XML, and YAML data structures.
