Schema Markup Validator

Validate pasted JSON-LD or schema script tags and flag missing context, type, and key content fields.

Validate pasted JSON-LD or schema script tags online and catch missing context, type, and important structured data fields before publishing.

Por qué la gente usa esta herramienta

Schema Markup Validator helps you review structured data quickly when you need to catch broken JSON-LD, missing fields, or weak markup before shipping a page.

  • Check JSON-LD markup before publishing a page, template, or CMS update.
  • Review structured data during audits, QA, and rich-result troubleshooting.
  • Spot missing context, type, and key content properties in pasted schema blocks.

Cómo usarla

  1. 1Paste the JSON-LD or schema script tag into the validator.
  2. 2Review the parsed type, required context, and any detected issues.
  3. 3Fix the markup source, then validate the updated version again.

Best practices

  • Validate the final page markup after template or plugin changes, not just the source draft.
  • Keep the schema aligned with visible page content so the markup stays credible.
  • Use the most relevant schema type instead of stuffing many unrelated types into one page.
  • Retest after edits because one missing comma or quote can invalidate the whole block.

Common mistakes to avoid

  • Do not publish malformed JSON-LD and assume search engines will fix it for you.
  • Do not add structured data that the visible page does not actually support.
  • Do not ignore missing context or type fields when validating schema.
  • Do not treat schema markup as a substitute for strong page content or technical hygiene.

Preguntas frecuentes

Respuestas útiles

What does a schema markup validator check?

It checks whether the pasted structured data is parseable and whether key schema elements such as context, type, and important properties are present.

Why validate JSON-LD before publishing?

Validation helps you catch syntax and field issues early so the markup has a better chance of being understood correctly after release.

Is valid schema enough to earn rich results?

No. Valid schema is only one requirement. The page still needs eligible content, clean implementation, and alignment with search engine guidelines.
