How it works
- Paste the URL you want to inspect (for example
https://example.com/page). - The tool fetches the live page and scans the HTML for embedded structured data.
- It parses both JSON-LD blocks and inline Microdata attributes.
- You get a list of every detected schema type and its key properties.
What it checks
- JSON-LD blocks — the modern
<script type="application/ld+json">markup Google prefers. - Microdata — inline
itemscope/itemtypeattributes in the HTML. - Schema types — Article, Product, FAQPage, Organization, BreadcrumbList and more.
- Key properties — the main fields declared within each type.
- Multiple entities — surfaces several schema blocks on one page.
- Type coverage — a quick read on whether the right type is present.
Common use cases
- Confirming rich-result eligibility — verify a Product or FAQ schema is actually on the page.
- Debugging a deployment — check that a CMS or plugin output the markup you expected.
- Competitor research — see which schema types ranking pages use.
- Pre-launch QA — make sure new templates ship with the intended structured data.
Example
Inspect a recipe page and you might see JSON-LD for both Recipe and BreadcrumbList, confirming Google can read cook times and the site path — while a product page you expected to carry Product markup comes back empty, pointing to a missing template.
Frequently asked questions
Is the Structured Data Checker free?
Yes — completely free, no signup and no limits. Check as many pages as you like with real, live data.
Does having schema guarantee rich results?
No. Valid structured data makes a page eligible for rich results, but Google decides when to show them based on quality and relevance. Detecting the right type is the first step; well-formed, accurate properties matter just as much.
How do I add the schema I'm missing?
Generate clean JSON-LD with the Schema (JSON-LD) Generator and validate other tags with the Meta Tag Analyzer. Learn which types help and how to use them in our structured data guide.
