Progressive web apps (PWAs) have revolutionized the way businesses approach app development. By combining the best features of websites and native mobile applications, PWAs offer an unparalleled user experience that drives conversions, boosts engagement, and reduces development costs.
The impact of progressive web apps on business is undeniable. For instance, Alibaba experienced a 76% increase in conversions, Forbes saw a 2x boost in engagement, and Flipkart recorded a 40% rise in user retention after adopting a PWA. The message is clear – if you aren't using PWAs, you're missing out on higher conversions, better engagement, and lower development costs.
So, what is a progressive web application? Simply put, it's a website built using web technologies that provides a user experience similar to that of a native mobile or desktop application. Like a website, a PWA can run on multiple platforms and devices from a single source code. Moreover, like platform-specific apps, you can install a PWA on your device, which can work offline and in the background by integrating with other applications installed on the device.
When you visit Starbucks.com on your phone, the site lets you browse the menu, customize orders, save favorites, and pay – just as Starbucks' mobile app does. Yet, as a website, it requires no download or space on your home screen. With faster load times and push notifications, Starbucks delivers app-style convenience accessible from your mobile browser.
PWAs offer many business benefits. They increase your application's loading speed, improving the user experience. eBay, for instance, saw a 0.5% increase in "add to cart" actions after improving its loading time by 100 ms through PWA implementation. Secondly, PWAs make the installation process faster than a native mobile application, where you must complete at least three steps (redirection to Play Store, downloading the app, and launching the app) to install the app. Weekenddesk encouraged users to install its PWA on the second page they visited and increased its conversion rate by 2.5%.
