Structured Data Audit

Your structured data, read the way Google reads it

Structured data is the only language Google and answer engines read without ambiguity. This tool extracts your page JSON-LD, lists the types present, identifies the essential ones missing, and hands you the exact code to paste.

Free, no account, no daily limit

The four types that truly matter

TypeWhat it brings
OrganizationYour brand identity card: name, logo, official profiles. Without it, neither Google nor AI knows who you are.
WebSiteEnables an internal search box directly inside Google results.
BreadcrumbListShows the breadcrumb under your title in results, which lifts click-through rate.
FAQPageThe format most reused by generative AI: one question, one short self-contained answer.

Why this weighs more since AI arrived

An answer engine must choose what to cite. Faced with free prose, it has to interpret. Faced with structured data, it reads an explicit, attributed, unambiguous statement. With equal content, the structured page gets quoted and the other is ignored.

The sameAs property of your Organization entity deserves particular care: it formally links your site to your official profiles and to public entity databases. That link lets an AI state with confidence that your site and your brand are the same entity.

Frequently asked questions

Should structured data be on every page?
Organization and WebSite go once, usually on the homepage. BreadcrumbList goes on every deep page. FAQPage only on pages that genuinely contain visible questions and answers.
Does FAQ markup still show rich results?
Google heavily reduced FAQ rich results from 2023. The markup still matters: it structures your answers for generative engines, which reuse them readily.
Can I invent reviews or ratings?
Never. Marking up fake reviews risks a manual penalty and is a deceptive practice. Only mark up what is genuinely visible on the page.
Is the tool free?
Yes, entirely free and no signup required.
