About SEOMarkup Structured Data Schema Inspector
Inspect, copy, and validate every piece of JSON-LD structured data on any page — in one click.
SEOMarkup Inspector parses every <script type="application/ld+json"> block, flattens @graph arrays into individual schemas, and gives you an organized tree view with full-text search. No more squinting at View Source.
━━━━━━━━━━━━━━━━━━━━━━━━━
WHAT YOU GET

• Click a schema type to jump straight to its Schema.org documentation
• Inline error banner when JSON-LD is malformed — see exactly which block broke and why

PRIVACY
━━━━━━━━━━━━━━━━━━━━━━━━━
No data leaves your browser. We use the activeTab permission only, which means SEOMarkup Inspector can read structured data on the page you're currently looking at — and only when you click the icon. We do not collect, store, transmit, or sell any data. There is no analytics, no telemetry, no remote code, no third-party requests.
