A schema checker that reads your live structured data
Structured data is the schema.org markup that helps search engines understand your page — and it's what makes rich results like star ratings, FAQs, and breadcrumbs possible. This schema checker fetches the live page, pulls out every <script type="application/ld+json"> block, and shows you what's there: which schema types are declared, whether each block is valid JSON, and the fields inside. Each block is displayed as its own clean, formatted card rather than a wall of raw log output.
A JSON-LD validator that catches real errors
The most common structured-data problem is the simplest: a JSON-LD block that doesn't parse. A missing comma or an unescaped quote makes the whole block invisible to search engines, and it's easy to miss by eye. This JSON-LD validator parses each block and reports the exact syntax error when one fails, so you can find and fix it fast. It also flags the two things the spec always requires — a @context and a @type — since a block missing either won't be understood as structured data at all.
Check structured data types at a glance
When you check structured data here, we list every schema.org @type found across the page — Organization, WebSite, Product, FAQPage, BreadcrumbList, and so on — including types nested inside a @graph or an array, which many tools miss. That gives you a quick inventory of what a page is telling search engines about itself, which is exactly what you want when auditing a template or debugging why a rich result isn't showing.
On rich result eligibility
We report what your structured data contains — the types, the fields, and any parse errors — factually. What we deliberately don't do is guess whether a given block will earn a rich result, because that depends on Google's specific, frequently-changing requirements for each result type, plus factors only Google can see. For that authoritative call, run the block through Google's Rich Results Test, which checks eligibility for specific rich result types directly. Think of this tool as the fast, clean pre-check you run first — and Google's as the final word on eligibility.
