AMP's unique selling point is the almost-instant delivery (PURE SPEED), a characteristic that makes AMP the perfect fit for the first user interaction with your site. Progressive web app's enable much more interactivity and engagement-enabling features, but their first load is hindered by the fact that the site's Service Worker, and therefore its assets and app shell, are only accelerating delivery on subsequent loads.
Mobilegeddon in April 2015 when they started to boost the rankings of mobile-friendly websites in mobile search results, to 2016 when Accelerated Mobile Pages got introduced and 2017 when progressive web apps started being supported by the Chrome browser, the Web technology evolved in a spectacular way and so did the businesses that knew how to take advantage of the newer trends. PWAs are 3x more likely to be downloaded that a native app and always up-to date with the newest info from your website. PWA uses almost 90% less data to subscribe!
AMP stands for Accelerated Mobile Pages, a Google-backed project designed as an open standard for any publisher to have pages load quickly on mobile devices. On Feb. 24, 2016, Google officially integrated AMP listings into its mobile search results. This give you the opportunity to get into Google Mobile Search, this can be a huge increase as much or more than 50% in organic search growth with a AMP enhanced website. AMP websites render from 15 to 85% faster than a traditional website and that's very important to Google.
Progressive Web App's (PWAs) another Google backed project, PWAs are web applications that load like regular web pages or websites but can offer the user functionality such as working offline, push notifications, and device hardware access traditionally available only to native mobile applications. Progressive Web Apps (PWA) are experiences that combine the best of the web and the best of app's. Native app store app's have become hugely popular in the past through features such as push notifications, working offline, smooth animations and transitions, loading on the homescreen and so on.
