Structured data
Structured data encodes entities and relationships using a shared vocabulary such as Schema.org.
How it works
JSON-LD can state article, product, organization, breadcrumb, or dataset properties explicitly while the visible page communicates the same facts to people.
How to validate it
Validate syntax, compare structured values with visible content, and version both when facts change.
Common failure
Markup that contradicts or invents visible content can be ignored and undermines trust in every machine-readable field.
Machine-readable editions
The same article is available as Markdown and JSON. These alternates are linked here but are not submitted through the sitemap or IndexNow.
