Instantly see: • Which schema types (Product, Article, Review, FAQ, Breadcrumbs, and more) are on the page • Missing required fields that could block rich results in Google Search • Missing recommended fields that improve how your content appears in search • Common copy-paste mistakes, like a property from one schema type left on the wrong type • Raw JSON-LD data for any page, viewable in one click • A direct link to Google's Rich Results Test for official validation No account, no sign-up, no data sent anywhere. Everything runs locally in your browser, and only scans when you click the icon.
