Structured data monitoring: detect broken JSON-LD

Rich results depend on markup that still parses and still contains the fields you promised. Structured data monitoring watches for parse failures, missing types and field loss on the templates that earn those results.

Updated 2026-09-01

What breaks in practice

  • A component fails to render, so the JSON-LD script is empty or truncated.
  • A designer wraps the block in a way that comments it out.
  • A required property is renamed or left null after a CMS field change.
  • Two graphs disagree about the same product URL.

How to monitor it

Pick one URL per template that emits schema. Watch for structured data changes and validity. If a specific string must remain, add a custom check. TechDash ships structured data change and validity checks as part of the 77.

Questions

Do you need a rich-results test on every check?

A local parse and field watch catches most regressions. Use Google’s rich results test when you need their current interpretation.

What if marketing edits product copy?

Copy changes can be fine. A disappeared sku, offer or availability field is not. Watch the fields that eligibility depends on.
