Overview
Product summary
Review the store description, core capabilities, and common use cases.
The AMP Validator will check the current page to see if it is an AMP page and then run it through the AMP validator and report if the page passes (green) or fails (red) via the extension icon.
If there are any warnings or errors it'll list the number underneath the extension icon and clicking the icon will display the warnings and/or errors.
If the current page is not an AMP page and one is available via the extension icon turns blue and clicking it will load the AMP version of that page.

Not working on Localhost
This tool is producing a false positive. I see the following errors after validating my document: 1. The mandatory attribute 'amp-custom' is missing in tag 'style amp-custom'. 2. Custom JavaScript is not allowed. 3. The tag 'style amp-custom' appears more than once in the document. #1 and #2 are both legitimate in my current situation. A Google Optimize script (which also adds internal styles) was inadvertently added to an AMP page. However, 'style amp-custom' does not appear more than once. It appears that the check for this might only be counting the number of occurrences of a 'style' tag rather than a 'style' tag with the 'amp-custom' attribute.
有个Bug，扩展显示AMP页面ERR，但是我试了4个AMP验证网站，都验证通过了。
Good APP for Dev SEO ASP.net MVC
No entiendo por que en algunos sitios el icono se queda de color gris y en la documentación de la extensión no hay especificación para ese color.
Great little indicator.
Best extension for Chrome!
