How to Use Schema Markup Validator

Paste your JSON-LD structured data markup into the editor and click Validate. The tool checks for required and recommended fields based on the @type you declared, flags missing properties, and highlights syntax errors. Fix any issues before deploying — invalid schema markup is ignored by search engines and misses rich result eligibility.

1

Paste your JSON-LD

Copy your <script type="application/ld+json"> block content and paste it into the editor.

2

Validate

Click Validate to check structure, required fields, and JSON syntax.

3

Fix flagged issues

Address missing required fields (like @type, name, or url) and correct any JSON syntax errors.

4

Re-validate and deploy

Validate again after fixes, then paste the corrected markup back into your page.

Frequently Asked Questions

What schema types are supported?+
Common types like Article, Product, FAQPage, BreadcrumbList, LocalBusiness, Event, and Recipe — the most frequently used types for rich result eligibility.
Does passing this validator guarantee rich results?+
No. This checks markup structure. Google applies additional editorial quality signals before showing rich results. Valid markup is necessary but not sufficient.
Should I use JSON-LD or Microdata?+
JSON-LD is Google's recommended format. It lives in a <script> tag separate from your HTML, making it easy to add, update, and debug without touching content markup.
