Technical SEO check
Unparseable JSON-LD
A parser cannot evaluate individual fields inside a JSON-LD block that is not valid JSON. Parse failures belong in their own critical gate.

What this finding means
A delivered script block declared as JSON-LD cannot be parsed into a JSON value, so its nodes and properties are unavailable for structured-data evaluation.
Evidence to preserve
- Affected page and script-block identity
- Parser error and bounded source context
- Response, language, canonical, and indexability
- Separation from field-level schema recommendations
How to repair the cause
- Correct JSON syntax and escaping
- Fix template interpolation that emits invalid commas or quotes
- Validate generated blocks before publication
- Retest the full graph after parsing succeeds
How to verify the fix
Fetch the page again, parse every JSON-LD block, then run node and field validation only on successfully parsed graphs.
Valid JSON is only the first gate. It does not prove the vocabulary or search-feature requirements are satisfied.
