Schema checker.
Structured data is how an assistant learns your name, type, location, offers and FAQs as facts instead of guesses. Paste any page. You get every JSON-LD block, its types, and what is missing.
What this checks, and why it matters
Structured data is the one place where you state facts about your business in a form a machine cannot misread: your name, type, address, hours, offers, and the questions you answer. Assistants and search engines both use it to confirm what the page text says.
The checker pulls every JSON-LD block from the page, parses it, lists the declared types and flags the properties each type is expected to carry: a LocalBusiness without an address, a Product without offers, an Article without a date. Invalid JSON is flagged too, because one stray comma hides the whole block.
If the page has no structured data at all, you get a draft Organization or SoftwareApplication block built from the homepage to check and paste into the head.
The full picture
This is one check. The scan is all of them, plus what assistants actually say.
A free scan asks ChatGPT your customers' questions, shows who gets recommended instead, runs the technical audit, and drafts the fixes.
