What is JSON-LD Validation?
- JSON-LD Validation
- JSON-LD validation is the process of confirming that a page's structured data parses correctly and resolves to the types and relationships it intends. It matters because invalid JSON-LD fails silently: consumers discard the entire block without warning, so a page can appear to carry rich structured data while presenting none.
01 In practice
Validation covers more than syntax. A block can parse cleanly and still be broken in meaning, most often through references to an @id that nothing on the page defines, which tells an engine to look something up and hands it nothing.
Because the failure is invisible in a browser, validation belongs in the deployment process rather than in an occasional audit. A template change that breaks the graph will not look like anything until visibility moves months later.
