Schema markup validator for rich results

Structured data (usually JSON-LD) helps search engines understand entities like Organization, Product, FAQ, and Article. This validator finds schema on a URL or pasted markup, then checks common required and recommended properties so you can fix incomplete or invalid nodes.

What good schema looks like

Prefer JSON-LD in the page head or body, keep types accurate, and avoid inventing properties. Match visible content—do not mark up offers or FAQs that users cannot see. Re-validate after theme or CMS updates.

How to use the report

  • Review errors first, then warnings for missing recommended fields
  • Confirm each node type matches the page purpose
  • Test key templates: home, product, article, contact
  • Combine with Google’s Rich Results mindset—eligibility is never guaranteed

Frequently asked questions

Is this an official Schema.org validator clone?

No. It covers common practical checks for popular types to speed up remediation.

Will valid schema raise rankings automatically?

Schema mainly improves eligibility for rich displays; content quality still drives rankings.
