AMP Validator

The AMP Validator is a browser extension that automatically validates AMP (Accelerated Mobile Pages) on any webpage you visit. It checks whether the current page adheres to AMP standards and provides immediate visual feedback through the extension icon. This tool is essential for web developers, publishers, and site owners who need to ensure their AMP pages are correctly implemented for optimal performance and search engine visibility.

Key Features

• Automatic Validation: Every time you load a page, the extension runs it through the official AMP validator. The icon turns green if the page passes validation, or red if it fails, giving you an instant status check without manual intervention.
• Error and Warning Indicators: When validation fails, the icon displays the count of errors and warnings underneath. Clicking the icon opens a detailed list of all issues, allowing you to quickly identify and fix problems such as missing required tags, invalid attributes, or incorrect markup.
• AMP Discovery for Non-AMP Pages: If the current page is not an AMP page but has a linked AMP version via <link rel="amphtml" href="...">, the icon turns blue. Clicking it loads the corresponding AMP page, making it easy to switch between standard and AMP versions for comparison or testing.
• Seamless Integration: The extension works silently in the background, requiring no configuration. It is useful when developing AMP pages locally, reviewing content on live sites, or auditing third-party implementations to ensure compliance.

By using the AMP Validator, you can catch validation errors early, improve page performance, and maintain compatibility with Google's AMP requirements. Note that installation implies acceptance of Google's Terms of Service and Privacy Policy.
