Accelerated Mobile Pages (AMP) is an open-source HTML framework developed by Google to create lightweight, fast-loading web pages optimized for mobile devices. It simplifies the structure of web pages by using a streamlined version of HTML, CSS, and JavaScript, ensuring quicker performance and better mobile usability.

A key feature of AMP is its reliance on the AMP Cache, a proxy-based content delivery network (CDN). This CDN caches AMP pages, allowing them to load more quickly when accessed through platforms like Google, Bing, or Twitter. Instead of linking directly to the original webpage, these platforms often direct users to the cached version hosted on the AMP Cache.

While AMP enhances page speed and mobile experience, it is important to note that Google does not consider AMP as a direct ranking factor in search engine optimization (SEO). However, faster-loading pages can indirectly improve user engagement and satisfaction, which may positively influence rankings.

In summary, AMP is a tool designed to deliver fast and efficient mobile web experiences by optimizing page structure and leveraging caching technology.
