Schema Markup Checker

The Schema Markup Checker is a free technical SEO tool that helps website owners, bloggers, and SEO professionals check and validate structured data (schema markup) on a webpage. Schema markup is a form of structured data that helps search engines better understand the content of a page and display rich results in search listings.

Structured data can enhance search results with rich snippets such as star ratings, FAQs, breadcrumbs, product details, events, and more. When schema markup is missing, incorrect, or invalid, search engines may ignore it, preventing your website from gaining enhanced visibility in search results.

Using the Schema Markup Checker, you can quickly detect which schema types are implemented on a page and identify errors, warnings, or missing fields. This helps ensure your structured data follows Schema.org and Google guidelines, improving eligibility for rich results.

How to Use the Schema Markup Checker

Using the Schema Markup Checker is very simple. Enter the webpage URL (for example, https://example.com) into the input box and click the Check button. The tool analyzes the page and displays detected schema markup along with validation results.

You can use this tool to:

  • Check structured data implementation

  • Improve eligibility for rich results

  • Fix structured data issues
