Machine-readable markup that describes a page's content and entities.
Structured data is standardized, machine-readable markup added to a web page to describe its content, products, articles, FAQs, organizations, and more, so machines can interpret it unambiguously. Implemented most commonly with Schema.org vocabulary in JSON-LD format, structured data helps both traditional search engines and AI systems understand entities and relationships on a page. Rich, accurate structured data improves eligibility for rich results and can strengthen the signals AI engines use when citing content.
