About the service
Schema Support Checker is an independent, free tool to help website owners review JSON-LD and HTML structured data. The service is not affiliated with Google, Schema.org or Microsoft.
Free access
All checker features are free, with no user accounts, daily usage quotas, payment plans or required API keys. Browser memory and file-size limits apply for reliability and safety. Availability also depends on the visitor's device, internet connection and hosting uptime. We do not guarantee uninterrupted service.
Informational results, not certification
Syntax, schema and Google feature assessments are limited automated heuristics based on dated information. They are not official validation, legal advice, SEO ranking guarantees or a rich result certificate. Verify important changes with Schema Markup Validator, Google Rich Results Test and published-page evidence.
Data accuracy and corrections
Do not enter false product, price, location, review, rating or availability claims. Auto-fixes are proposed only. Check all corrected files before deploying them. You remain responsible for your content and compliance with third-party platforms.
Acceptable use
Do not use the service to distribute malware, exploit vulnerabilities, upload confidential data you do not control, or interfere with its operation. Bulk checks should stay within stated browser-safety limits.
Third-party websites and advertising
External resources, projects and optional advertising may have their own policies. Ads, if ever activated, will be labeled or clearly distinguished from editorial and tool results. Our Privacy Policy describes relevant data practices.
Changes and limitation of liability
Features and documentation may change. The tool is provided as-is, without guarantees that diagnostics or fixes are complete, or that the site will always be available. To the extent permitted by applicable law, the publisher disclaims liability for losses caused by relying solely on the tool's recommendations.
