Structured Data & Rich Results Validator
Fetch any URL, extract every JSON-LD structured-data block, and validate it — see the schema types found, spot invalid JSON and missing required fields before Google does.
How it works
Paste a URL
Enter any URL — we fetch the page and extract every JSON-LD block from the HTML.
See the schema types
Each JSON-LD script tag is parsed and the schema.org types are identified (Article, FAQ, Product…).
Review the issues
Missing required fields and JSON parse errors are flagged with actionable messages.
Frequently asked questions
What is JSON-LD structured data?
JSON-LD (JavaScript Object Notation for Linked Data) is the format Google recommends for embedding schema.org structured data in your pages. It lets search engines understand page content and eligibility for rich results like FAQ accordions, review stars, and breadcrumb trails.
Will this tool tell me if I qualify for rich results?
It checks for common required fields and JSON validity, which covers the most frequent reasons a page fails Google's rich results eligibility. For Google's official verdict, also run the page through Google's Rich Results Test.
Why does this page show 0 structured data blocks?
Not all pages include JSON-LD. Some sites use Microdata or RDFa instead (embedded in HTML attributes rather than script tags) — this tool only extracts JSON-LD blocks.
What schema types are checked for required fields?
Article / BlogPosting / NewsArticle (headline, author, datePublished), Product (name), FAQPage (mainEntity), LocalBusiness / Organization (name), and BreadcrumbList (itemListElement). All other types are extracted and displayed without field-level validation.
