Schema and JSON-LD checker
Enter a domain to check the JSON-LD structured data on its homepage.
JSON-LD describes a page in a form machines can read: who runs the site, what it is about and which questions it answers.
This tool reads the homepage as served, without running JavaScript, so it does not see markup added only in the browser.
Questions
Which pages does it check?
Only the homepage. Check other templates with a page-level validator.
Does valid Schema guarantee citations?
No. It makes your page easier to understand, but citations also depend on authority and on what people ask.
