Schema Markup Validator
<p class="lead">Enter any URL to fetch the page and extract all <code>application/ld+json</code> script blocks. The validator checks each block against basic schema.org shape rules and shows you exactly which fields are missing or misconfigured.</p>
Why validate structured data?
Invalid or incomplete schema markup fails silently. The page renders normally, but Google cannot generate rich results because required fields are missing. A validator catches these issues before they cost you rich-result eligibility.
Common failure patterns include missing @context, wrong @type casing, omitted required fields like datePublished on Article schema, and JSON syntax errors introduced when schema is dynamically generated.
After validation
Use the "Test in Google Rich Results Test" link to confirm eligibility for specific rich result types. Google's tester goes beyond structural validation to check whether the schema qualifies for a real rich result in search.
