Web Apps

Progressive Web Apps are a sufficiently established technology that big players like Twitter, Ola, Olx, MakeMyTrip, Forbes and AliBaba have adopted them with great success.
Building a high-quality Progressive Web App has incredible benefits, making it easy to delight your users, grow engagement and increase conversions.

At Centillion we believe in the concept of a PWA and can build a high performing App which can transform your business and give it a fighting edge over your competitors. Let’s have a closer look at AliBaba.com’s story.

Alibaba.com increases conversions on the mobile web by 76% with Progressive Web App


Alibaba.com is the world’s largest online business-to-business (B2B) trading platform, serving 200+ countries and regions. After upgrading their site to a Progressive Web App (PWA), they saw a 76 percent increase in total conversions across browsers.


Building great mobile experiences is an indispensable part of Alibaba.com’s success. The mobile web is their primary platform for discovery on mobile, so they’ve always focused on design and functionality. They found it difficult to build an engaging experience for the mobile web, however. They looked
at the mobile web as a platform to shift non-app users to the app, but many preferred to stay within a browser. “Users consider having to download an app to browse or complete a transaction an unnecessary barrier, compared to the quick, easy solution of browsing directly from their mobile browser” says Zou Yu, director of Alibaba.com’s mobile team.


Alibaba.com recognized that to build an effective mobile presence, they needed to understand how two different user segments—native app users and mobile web users—interacted with their business. They wanted to deliver a great user experience for both first-time visitors (in the hopes of re-engaging them) and repeat visitors (who are more loyal to the site). Alibaba.com built a PWA that led to a fast, effective, and reliable mobile web experience. The new strategy delivered a 76 percent increase in total conversions across browsers. (A conversion corresponds to visits that result in direct contact with a supplier.) For mobile web users on Android, Alibaba.com integrated features that helped users re-engage with the site. The company implemented an “Add to Home Screen” prompt, which resulted in users re-engaging four times more often than other mobile users. They also noticed that re-engagement on the web was comparable to that of their native app. For push notifications, the open rate on the mobile web is the same as that on the native app. The new strategy also delivered a much better user experience across platforms. The investment in the mobile web increased monthly active user rates on iOS by 14 percent. On Android devices where re-engagement capabilities like push notifications and Add to Home Screen were enabled, active user rates increased by 30 percent. “Delivering a mobile-first, user-centric mobile site that harnesses the best of the native app, with all the accessibility and versatility of the mobile web, is key to maintaining our competitive edge and the path to better conversions,” Zou Yu says.
