PILLAR 4, AUTHORITY NETWORK · 4.1 Structured data validityHighVerified
Invalid JSON-LD syntax
Structured data only works if it parses. A JSON-LD block with a syntax error, a missing comma, an unclosed brace, is ignored wholesale, so the rich-result eligibility it was meant to provide is lost.
What it is
Malformed JSON-LD.
Why it matters
Broken markup can’t be parsed; no rich-result eligibility.
How to fix it
Fix JSON; validate with Rich Results Test.
How to find it on your site
- Run the page through the Rich Results Test and the Schema Markup Validator.
- Read the errors and locate the syntax fault in the JSON-LD.
- Fix the JSON and re-validate.
- Add validation to your build so broken markup never ships.
Cross-reference to ranking and citation factors
Invalid structured data is discarded entirely, removing any rich-result and entity benefit. Valid markup is the precondition for all of it.
Impact
Medium-high for rich results. Direct.
