Why Progressive Web Apps Are Getting Higher Conversions?

Published Date

In 2015, Google coined the term progressive web apps as they introduced them for the first time into the business universe. The name is apt on so many counts – ‘Progressive’ because Google was creating a flexible, adaptable app using only web technologies. ‘Progressive’ because these web-based applications were using new features supported by modern browsers that let users upgrade web-based applications to progressive web applications independent of the native operating system. ‘Progressive’ because it lets people interact with it as if it were an app without the hassle of downloading it.

A progressive web application combines the best of a website with the best of native apps to create an unparalleled experience for mobile users. Small wonder then that PWAs are continuing to see their popularity soaring.

What are progressive web apps?

PWAs are special web applications that are accessed like normal websites but offer the features of native apps such as offline usability, push notifications, and access to device hardware.​​​ No need to visit Google Play Store or the iOS App Store to download the app. And yet your app can give the same mobile app experience to users without the complexity of developing one.

The stars of the PWA success story

PWA examples are all around us but let’s look at well-known brands who have used Progressive Web Apps with phenomenal success in customer satisfaction, higher engagement and conversion rates.

Starbucks created a PWA over 99% smaller than their downloadable iOS app. 233 KB of data storage versus 148 MB for their iOS mobile app is an important differentiator.. It allows users with networking issues to browse, access, and load menu items into their cart. When online, the items can be purchased. So, on the go customers or rural communities with unreliable networks are benefitted. Their PWA has more than doubled theirweb app orders.

Twitter created the Twitter Lite PWA so that users could easily navigate between multiple accounts while decreasing data usage up to 70%. Their ‘save to homepage prompt’ for users is very popular. 600KB is all it takes compared to the 2.5MB required for their traditional app.  65% increase in pages per session, 75% increase in Tweets, 20% lower bounce rate added to  2,50,000 daily users, over 328 million monthly users, and still counting. If you need convincing about the benefits of PWA, this is it.

MakeMyTrip’s PWA was created to reach out to those who prefer to book a vacation through a web browser. The new PWA experience has seen 3 times increase in conversions by reducing page loading time by 38%, 20% reduction in their bounce rate, 160% increase in user sessions, and has improved their target audience to users in 24% more cities in India.

Uber’s PWA  was developed for new customers who preferred booking rides via a web browser or who used low-speed networks. The Uber PWA designed to make car booking viable on low-speed, 2G networks works well for riders on low-end devices, which may not be compatible with the native Uber app. Its 50KB web app can be loaded within 3 seconds even on 2G networks.

The cogs in the PWA wheel – PWA Components

Building progressive web apps call for a web app manifest, service worker, and the use of HTTPS.  Beyond these features, it is up to you which enhanced web APIs you wish to leverage to deliver the ultimate user experience.

1. Service Workers

A service worker is a script that runs in the background when a user accesses a web page that is powered by a PWA.  It is a special kind of java file that your browser runs outside the main browser thread. It is essentially acting like a proxy that sits between the browser and the network, It intercepts and handles any requests from the PWA’s visual interface.  Since content is cached on the device (laptop or mobile) your page loads much faster.

2. PWA Web app manifest 

The web app manifest provides information like the name and description of the PWA compressed in a JSON text file. The manifest simplifies the installation of the web app on the home screen, speeding up access and ensures users’ experience is smooth.

3. HTTPS is necessary for PWA

All PWAs leverage the Transport Layer Security (TLS) protocol. They use HTTPS for safe and secure hosting to ensure the privacy of communications and integrity of data between your app and the app user. The service worker makes websites accessible over HTTPS with users being intimated that the connection is secure.

4. PWA Icon

Just like a mobile app, the PWA icon will sit independently on the mobile screen. The display of the icon confirms to the user that the PWA is installed successfully on the device. Images of various sizes are already defined in the web app manifest and are placed in the images folder to be displayed as a home screen icon when a user “installs” the PWA.

Key features of progressive web apps

Although not a new technology, progressive web applications with their hard to beat features are becoming increasingly popular now. In their search for better solutions, businesses are looking to PWAs to meet their business goals.

1. Fully responsive and device compatible  

PWAs are multi-device compatible and work equally well on mobile phones, desktops, laptops, tablets and all hand-held smart devices. They can also be accessed from any web browser like Chrome, Firefox, Safari as these are based on compatible technologies.

2. PWA is connectivity independent

Service workers enhance PWAs by allowing an app to provide offline
