JSON-LD

JSON-LD is the format most structured data is written in: a small block of machine-readable JSON embedded in a page's HTML, invisible to visitors, that describes what the page contains.

{
  "@type": "Article",
  "headline": "How to store wine",
  "author": { "@type": "Person", "name": "Ana Silva" },
  "dateModified": "2026-07-01"
}

Search engines and AI assistants read JSON-LD to understand a page without guessing from its layout. Declaring the page's type, author, and dates in JSON-LD makes it easier for them to trust and cite your content.
