Schema markup checker
See which structured data is on a page, which sameAs links connect your brand to profiles elsewhere, and what is missing.
No account needed. We don't store what you enter or the result.
What this tool checks
- We fetch the page and read every JSON-LD block and all microdata, including nested types in an @graph.
- We count how often each type appears and flag JSON-LD that isn't valid JSON.
- We collect the sameAs links: they connect your organisation to LinkedIn, Wikipedia or your company registration, so search engines and AI systems can recognise your brand more easily.
- We check whether Organization, WebSite, BreadcrumbList and content types such as FAQPage or Product are present.
