Test JSON-LD live Live Test

Paste code, see the result immediately. The lab checks syntax, type and required fields while you type.

1What is it?

Editor on the left, check on the right. The blocks of the current page are already loaded when you open it. Errors are shown next to them with line and explanation.

2Why it matters

A missing comma makes the whole block invalid, and Google ignores it silently. In the lab you see it right away, not weeks later in Search Console.

3What TagSpion checks

Check	Rating
Syntax	red with line number for invalid JSON
@context and @type	red if missing or unknown
Required fields per type	red if missing · yellow for recommended fields

4How to fix it

Fix errors until everything is green, then copy and put it in the page as <script type="application/ld+json">.

<script type="application/ld+json">
{
  "@context": "https://schema.org",
  "@type": "Product",
  "name": "Tagliatelle al ragù",
  "image": "https://www.example.com/img/tagliatelle.jpg",
  "description": "Fresh egg pasta with slow-cooked beef ragù.",
  "offers": {
    "@type": "Offer",
    "price": "14.50",
    "priceCurrency": "EUR",
    "availability": "https://schema.org/InStock"
  }
}
</script>

Also test externally

The Schema Lab checks locally. For the final check there are two free tools:

Google Rich Results Test ↗search.google.com/test/rich-resultsShows which rich results Google can generate from the page. Schema Markup Validator ↗validator.schema.orgChecks all schema.org types, including those without rich results.

5Frequently asked questions

Does this replace Google's Rich Results Test?

No. The lab checks structure and required fields locally. What Google makes of it, only Google's test shows. Both together is ideal.
