Valid JSON-LD isn't the same as eligible JSON-LD. Here's the testing workflow that catches the difference.
Schema markup can pass every validator and still never trigger a rich result. Validation checks syntax. Eligibility checks whether Google trusts what you're claiming.
A Testing Workflow That Actually Works
- Validate syntax first with a JSON-LD linter to catch broken commas and types.
- Use Google's Rich Results Test to confirm the specific result type is eligible, not just valid.
- Match every schema claim to visible on-page content. Mismatches are the #1 cause of manual actions.
- Re-test after every template change. One layout update can silently break schema on thousands of pages.
Structured data is infrastructure, not a one-time task. Treat it like code that needs regression testing.
