FREE Schema Markup Validator

The Schema Markup Validator is a free, real-time testing tool built to ensure your structured data is optimized for search engine crawlers.

The analyzer identifies critical formatting gaps in your JSON-LD or microdata, pointing out exact lines with syntax errors or missing fields.

With this tool, you get a clear snapshot of how easily search engines can crawl, parse, and showcase your content with rich search elements.

Our tool accepts a page URL or manually copy-pasted structured data code as inputs to scan your structured data implementation.

The validator evaluates your code’s underlying architecture to report on your structured data health:

• Syntax & Format Validation: Instantly catches JSON-LD parse errors, unclosed brackets, nesting mistakes, and invalid characters before they break your page.
• Schema.org Context Verification: Confirms that your @context and @type declarations are accurate and meet correct formatting standards.
• Missing Required Fields: Spots omissions in key data fields for highly competitive schema types like Products, FAQs, Recipes, Events, and Videos.
• HTML Extraction: Pulls and tests nested JSON-LD or microdata directly from raw page code, saving you from manually copying scripts.

Our real-time checks reveal:

• Rich Result Eligibility: Automatically scans your code patterns to confirm whether your schema meets the minimum requirements to trigger interactive Google search features.
• Warning vs. Error Flagging: Separates critical errors from optional recommendations, which simply make your search listings more detailed and likely to be picked up.
• Nested Entity Integrity: Verifies that secondary schemas like reviews or aggregate ratings nested inside a product are correctly linked and readable.

• Nodes & Scripts: Shows you the total number of structured data blocks and script tags detected on your page.
• Errors: Critical issues that must be fixed. If this is above 0, search engines will likely fail to parse your schema, and you won't get rich results.
• Notices: Non-critical alerts highlighting missing optional fields (like shipping details or return policies) or policy context.
• Clean: Confirms that the specific block of schema has zero errors and is fully readable.
• Rich Result Eligibility (e.g., "Product Rich Result"): Confirms that your code successfully meets Google’s requirements to trigger interactive search snippets.

If you are new to structured data or trying to add a particular type of schema, you can use built-in examples to help you learn and build faster.

The examples include pre-configured, syntactically accurate templates for popular structured data types that often trigger rich search snippets like Products, FAQs, Recipes, Events, and Videos.

Copy the example structured data code for format and syntax and edit the details to quickly preview and verify schema for your pages before pushing live changes. 

• SEO Professionals & Marketers: Quickly draft, test, and debug JSON-LD markup for key pages to ensure rich feature eligibility.
• Web Developers: Validate code scripts on the fly as you build page templates, ensuring perfect execution before shipping code to production.
• Bloggers & Publishers: Improve your organic visibility by verifying that Recipe, FAQ, and Video schemas are clean and readable.
• E-Commerce Managers: Keep product listings, pricing updates, and stock availability schema perfectly synced to capture snippets like search carousels and AI visibility for product queries.
