The goal of AMP is to make web pages load faster on mobile devices, which can lead to a better user experience and higher engagement. AMP pages are designed to load quickly, even on slow connections or older devices. They also prioritize loading above-the-fold content so that users can see the most important content first.
AMP (Accelerated Mobile Pages) pages are also optimized for search engines, which can lead to higher visibility in search results. Google has stated that AMP pages may be given a slight ranking boost in mobile search results. Additionally, AMP pages are often displayed in a carousel of Top Stories in the mobile search results, leading to higher visibility and traffic.
