With the new Chrome AMP Validator extension, you can quickly spot and debug invalid AMP HTML pages. As you browse, it will automatically validate each AMP page visited and give an indication of the validity of the page.
AMP Validator Accelerated Mobile Pages (AMP) is an open source technology developed in 2015 by the AMP Open Source Project and supported by Google. It was announced in October 2015 as an internal project at Google. From 2016, pages supporting this technology began to be displayed as such in Google Search results. To allow the validation of these pages, AMP has implemented the Chrome extension AMP Validator. With this new extension, it is easier to notice and debug invalid AMP HTML pages. As new navigation is made, AMP Validator automatically validates each AMP page visited and then gives an indication of the page’s authenticity. AMP’s validation framework is an essential ingredient in ensuring the speed and authenticity of AMP pages.
