No more squinting at View Source. ━━━━━━━━━━━━━━━━━━━━━━━━━ WHAT YOU GET ━━━━━━━━━━━━━━━━━━━━━━━━━ • One-click inspection of all JSON-LD on the active page • Expandable tree view with full-text search and match cycling • Per-schema actions: copy as JSON, copy as tag, download as .json • 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 • Microdata and RDFa detection so you know when other structured-data formats are present • One-click validation via Google Rich Results Test and validator.schema.org (pre-filled with the current URL) • Works on any website — no setup, no account, no signup ━━━━━━━━━━━━━━━━━━━━━━━━━ WHO IT'S FOR ━━━━━━━━━━━━━━━━━━━━━━━━━ • SEO professionals — audit a client site in seconds. See every Product, Article, Organization, FAQ, BreadcrumbList, and more without leaving the page. • Web developers — debug your structured data before it ships. Catch malformed JSON-LD before Search Console does. • Content auditors and competitive researchers — see what schema your competitors use, copy it as a starting template, and validate before deploying. • Zero configuration — install and click • Tiny footprint — under 50KB total • Fast — opens instantly, no external requests • Private by design — see the privacy section below 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.
