Free Schema Validator for JSON-LD: Test Your Structured Data

Structured data tells search engines and AI assistants exactly what your content is about. Proper JSON-LD schema markup can unlock rich snippets in Google, improve AI citation accuracy, and boost click-through rates by 20-30%.

Citedy's free Schema Validator checks your JSON-LD markup for errors, missing properties, and Schema.org compliance.

How It Works

  1. Visit citedy.com/tools/schema-validator
  2. Enter any URL or paste your JSON-LD code
  3. Get validation results with specific error details
  4. See recommendations for improvement

Key Features

  • JSON-LD syntax validation — Catch malformed JSON before it causes issues
  • Schema.org compliance — Verify markup follows official Schema.org vocabulary
  • Missing property detection — Flag required and recommended properties that are absent
  • Multi-schema support — Validates Article, Product, FAQ, Organization, LocalBusiness, HowTo, and more
  • Rich snippet eligibility — See if your markup qualifies for Google rich results
  • AI readability check — Assess whether your schema helps AI platforms understand your content

Use Cases

Developers: Validate schema markup during development before deploying to production.

SEO professionals: Audit structured data across client sites for rich snippet eligibility.

Content teams: Ensure FAQ, HowTo, and Article schema is correctly implemented on content pages.

E-commerce: Validate Product schema with price, availability, and review data.

vs Paid Alternatives

Google's Rich Results Test is free but limited. Schema.org's validator checks syntax but not SEO impact. Citedy combines both with AI-readability analysis in one tool.

FAQ

Why is JSON-LD the recommended format?

Google officially recommends JSON-LD over Microdata or RDFa. JSON-LD separates markup from HTML content, is easier to maintain, and less prone to errors.

Does structured data improve rankings?

Not directly, but it enables rich snippets (stars, FAQs, prices in search results) which significantly improve CTR. It also helps AI platforms cite your content more accurately.

What schema types should I implement first?

Start with Organization (homepage), Article (blog posts), FAQ (FAQ pages), and Product (product pages). These have the highest impact on rich snippets.
