Common questions
What is Schema.org structured data?
Schema.org structured data is standardised code (usually JSON-LD) that you add to a webpage to help search engines understand its content. It enables rich results in Google Search — star ratings, FAQs, product prices, breadcrumbs — which can significantly increase click-through rates.
Why does this tool sometimes fail to fetch a URL?
Browsers enforce CORS restrictions that prevent fetching arbitrary URLs from client-side JavaScript. We use a public CORS proxy to work around this, but some sites block proxy servers or have strict firewall rules. For those sites, use Google's Rich Results Test directly.
What schema types does this checker detect?
It detects all JSON-LD scripts with @type declarations — including Organization, LocalBusiness, Article, Product, FAQ, BreadcrumbList, Event, Review, and 15+ more. It reports every @type value found in the page source.
