Fix parsing errors first
A stray comma, unescaped quote or truncated value can invalidate an entire JSON-LD block.

What this check covers
Use the validator after editing templates, CMS fields or injected scripts that produce application/ld+json markup.
- application/ld+json script blocks
- JSON parsing and empty block errors
- @context, @type and nested entities
- Repeated @id values across blocks
Review every entity
One script can contain an @graph or nested objects. Open the block and confirm each entity is expected.
Test eligibility separately
Valid JSON does not prove that a search engine supports the type or will show a rich result.
Source check or rendered check?
Use this page for one public URL and the markup returned in its source HTML.
Use the Chrome extension for a rendered tab, JavaScript-added markup, loaded-resource evidence, private pages and a fully local report.
Questions about json-ld validator
What does this JSON-LD validator check?
It parses each JSON-LD script, lists its entities and types, and flags structural issues found by SEOMarkup.
Can it validate pasted JSON-LD?
This page checks JSON-LD published at a public URL. A pasted-code mode is not included yet.
Why can valid JSON-LD still have warnings?
JSON syntax can be valid while identifiers, types or page context still need a manual review.
