Accelerated Mobile Pages (AMP) is an open-source HTML framework created by Google for creating stripped-down fast-loading versions of web pages optimized for mobile devices. As stated by Google, AMP is not a ranking factor.
Accelerated Mobile Pages (AMP) work by using a simplified and streamlined version of HTML, CSS, and JavaScript, specifically designed for faster performance.
There is a unique aspect of AMP that involves storing, or more accurately, caching: the AMP Cache. Major platforms that use AMP, like Google, Bing, and Twitter, utilize an AMP Cache – a proxy-based content delivery network (CDN) that caches AMP documents and makes them load faster. When these platforms link to an AMP page, they often link to the version on the AMP Cache.
