How to verify the findings

Schema Validator Plus is a fast local pre-check for JSON-LD before you paste markup into a page template or send it to an official rich-results test.

It parses raw JSON-LD or script tags, identifies schema types, checks common required and recommended properties, and produces a normalized copy-ready JSON block.

Common use cases

  • Quickly inspect Organization, WebSite, Article, FAQPage, Product, HowTo, and SoftwareApplication schema.
  • Find missing fields before handing markup to a developer or CMS editor.
  • Normalize script-tag JSON-LD into readable JSON for review.

How to use it well

  1. Paste a JSON-LD object, array, graph, or script tag.
  2. Run the validator and review errors, warnings, detected types, and recommended fixes.
  3. Copy the normalized JSON-LD and test important pages with official tools after publishing.
  4. Keep visible page content consistent with the structured data.

Practical tips

  • Structured data should describe content that is visible or clearly represented on the page.
  • Use absolute URLs for url, image, sameAs, and source references.
  • Avoid adding review, rating, price, or availability fields unless they are accurate and shown to users.

Limitations to know

  • This tool does not fetch a live page or validate eligibility for every rich result.
  • Search engines decide whether to use structured data in results.

FAQ

Q: Does this replace Google rich results testing?

A: No. Use it as a fast local pre-check, then validate important pages with official search tools.

Q: Can it parse script tags?

A: Yes. Paste raw JSON-LD or a script tag containing application/ld+json.
