Schema markup validator
Paste a page address. We read every JSON-LD block on it and check each item against what Google's own documentation requires and recommends — with a link to the rule. Free, no signup.
Reads JSON-LD only (not microdata or RDFa).
What does this check?
Each JSON-LD item whose type Google documents — LocalBusiness and its kinds (Dentist, Restaurant…), Organization, Product, Offer, Article, BreadcrumbList, Review, AggregateRating — against the required and recommended properties on Google's page for that type.
Why only Google's rules?
Because the point is what Google and AI assistants can use. schema.org allows far more; we report what Google documents and link to the page, so you can check us.
Is FAQ markup still worth it?
Google stopped showing FAQ rich results in 2026. The markup is not wrong — AI assistants may still read it — but it will not change how your result looks in Google.
