JSON-LD / Schema.org Structured Data Validation

Validates structured data that helps search engines better understand your pages and display Rich Results (rich snippets).

Measurement Items

  • Parse and validate JSON-LD format
  • Verify required fields by Schema.org type
  • Detect Google Rich Results–supported types
  • Check presence of Microdata and RDFa
  • Provide errors, warnings, and improvement suggestions
  • Include example JSON-LD snippets

Validated Schema Types

  • Core schemas such as Organization, WebSite, BreadcrumbList
  • Content-specific schemas such as Article, Product, FAQPage
  • Specialized schemas such as Event, JobPosting, LocalBusiness
  • Rating-related schemas such as AggregateRating, Review
  • Media schemas such as VideoObject, Recipe, Course

Benefits of Structured Data

  • Eligibility for Rich Snippets in search results
  • Improved click-through rate (CTR)
  • Better search engine understanding of content
  • Optimization for Voice Search and AI Search
  • Higher likelihood of Knowledge Graph inclusion

Testing Tool

Playwright-based browser automation collects structured data from actually rendered pages and applies Schema.org validation rules based on Google Rich Results Test standards. Performs JSON-LD parsing, required field validation, and Rich Results compatibility assessment.
