About this tool

Comprehensive documentation & audit utility guide

Verified Utility

AMP (Accelerated Mobile Pages) has strict markup rules — a single missing attribute can make a page invalid. This tool runs Google's own official amphtml-validator library against your markup, the same validation logic AMP-aware crawlers and Search Console use, so you catch issues before they show up there.

How it works

Provide AMP markup

Paste raw AMP HTML, or point at a live AMP page's URL.

The official validator runs

Google's amphtml-validator library checks it against the AMP spec.

Fix what it flags

Click an error to jump straight to the offending line.

What it checks

Mandatory AMP tags and attributes

Disallowed HTML/CSS/JS patterns the AMP spec forbids

Errors vs. warnings, each with exact line and column numbers
