AMP Validator

Use this bulk validator to check if one or more URLs (up to 10) are valid Accelerated Mobile Pages (AMP). If a submitted URL is not AMP, the tool will look for an AMP URL linked via the rel=”amphtml” tag and test it. This tool uses the official AMP Project validator but also checks the implementation of your AMP URLs: does the referenced canonical URL point back to the AMP with a rel=”amphtml” tag?

AMP Validator — Description & Usage

What Is This Tool?

The AMP Validator checks Accelerated Mobile Pages (AMP) markup to ensure your pages meet AMP HTML standards. It helps developers and content teams identify AMP-specific validation errors, missing required attributes, deprecated tags, and performance issues so pages can take full advantage of AMP’s fast-loading, mobile-first behavior.

  • Detects AMP validation errors and warnings (HTML, CSS, JS limitations).
  • Verifies required AMP components and attributes are present.
  • Helps ensure pages are eligible for AMP caches and featured placements.

Why Validate AMP?

Ensure Performance

Valid AMP delivers consistent, fast experiences on mobile — improving load times and engagement.

Maintain Discoverability

Valid AMP pages are more likely to be used in mobile carousels, stories, and Google caches.

How to Use This Tool (Step-by-Step)

  • Enter your AMP URL — paste the page URL (or upload AMP HTML) you want to validate.
  • Run the validator — the tool parses the AMP markup and reports errors and warnings.
  • Review detailed results — see line/element-level messages, missing attributes, and disallowed tags.
  • Fix issues — update your AMP HTML/CSS/AMP components and re-run until no critical errors remain.
  • Re-check for performance — ensure images, ads, analytics, and third-party components follow AMP best practices.

Pro Tips for AMP Validation

  • Use the official amp-validator rules as reference.
  • Prefer AMP components (e.g., <amp-img>, <amp-video>) over custom JS.
  • Minimize inline CSS and keep total CSS under AMP limits.
  • Re-validate after integrating analytics, ads, or dynamic content to avoid new errors.

Use the AMP Validator to ensure your accelerated mobile pages are compliant, fast, and eligible for enhanced search experiences.
