AMP URL is Invalid

What This Means

Google Search Console's AMP report shows this AMP page has validation errors. The page may have an AMP version that contains markup errors, missing required elements, or disallowed elements that prevent it from being valid AMP.

Why It Matters for SEO

An invalid AMP page cannot be served through the Google AMP cache or displayed with the AMP indicator in search results. The page falls back to the canonical HTML version. AMP validation errors are error-level because the AMP implementation is completely broken — not just imperfect.

What the Platform Checks

Cross-references GSC AMP report data with the technical audit. Fires for each page with AMP validation errors in GSC.

How to Fix It

• Open the GSC AMP report and review the specific validation errors for this URL.
• Use the AMP Validator (validator.ampproject.org) to test the AMP page and see detailed error messages.
• Common AMP errors: disallowed HTML elements (AMP has a strict allowlist); missing AMP boilerplate; invalid CSS; scripts not using AMP's custom script system.
• Fix errors in the AMP template and re-test with the AMP Validator before deploying.
