Building great mobile experiences is an indispensable part of’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.

Solution 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). 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, 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.
