Progressive Web Apps

Alibaba, eBay and Bloomingdale’s Dominate Mobile Commerce with Fast Progressive Web Apps

Progressive Web Apps allow speed and an engaging web experience to work simultaneously. See how Amazon and eBay lead in race the eCommerce mobile websites.

New technology enables website speed and engaging online experience to work simultaneously through full stack site speed optimization. eCommerce Progressive Web Apps (PWAs), AMP technology, and server-side rendering are a few of the tools that when combined correctly, yield sub-second websites with reliable and engaging front-end experiences, particularly on the mobile web.

Mobile web speed is an essential component of engagement and conversions from today’s loyal shoppers. eCommerce leaders are in a competitive race to become the best in their industry and if you aren’t prioritizing the mobile user experience, you are leaving money on the table and not to mention, the sought-after Google search ranking. To give you an idea of what the competitive landscape looks like, we are showcasing marketplace leaders, apparel giants, and go-to travel companies in this month’s list of leading eCommerce progressive web apps.

eCommerce Marketplaces

1. eBay - PWA + AMP

With 25M online sellers and over 150M active buyers, eBay — the multinational e-commerce corporation — understands the importance of using technology to connect people and build economic opportunity. eBay did not want to limit the opportunity of financial growth due to unstable internet connectivity or network conditions. This drove the eCommerce giant to enable 15 million Accelerated Mobile Pages (AMP) and begin adopting PWA technology, too. They’re now delivering a fast, optimized experience to their 900M monthly visitors.

2. Alibaba - PWA, the world’s largest online business-to-business (B2B) trading platform, found it difficult to create an engaging mobile experience. Once they found that mobile website visitors wouldn’t convert over to their native app, the company upgraded the mobile experience to a PWA which also replaced their mobile app as their vessel for re-engagement and home for loyal customers.

“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.” - Zou Yu, director of’s mobile team.

With the PWA, Alibaba’s mobile conversions increased by 76% and engagement grew by 4X due to the Add to Homescreen option.

3. Letgo - PWA

With over 10M monthly visitors and hundreds of millions of listings, Letgo is one of the biggest and fastest growing sites for local buying and selling. Surprisingly, the rising star struggled with creating an optimal checkout process, which left users feeling insecure about purchases.

Letgo chose to enhance their entire customer journey from browsing to checkout, by delivering a PWA for both mobile and desktop experiences. Their online community now benefits from a fast, reliable experience with multiple payment options (Venmo, PayPal, Apple Pay). Providing alternative payment options are important because this is one of the proven ways to design a mobile checkout flow that converts.


4. Bloomingdale’s - PWA

With a tagline of “Like No Other Store in the World,” Bloomingdale’s — an American luxury department store chain — wanted to create an online shopping experience that lives up to that of their brick and mortar locations. The Customer Loyalty OVP of Bloomingdale’s became passionate about providing customers with a relevant, engaging, and enjoyable shopping experience both online and in-store.

Bloomingdale’s PWA provides nearly-instant page loads for mobile users, as well as an intuitive path-to-purchase, helping to convert and build a loyal customer base.

5. Lilly Pulitzer - PWA

Lilly Pulitzer, the resort wear brand, has a traveling and on-the-go type of customer base. The Vice President of Digital Commerce explains mobile is a lifestyle for their clientele, so a seamless online experience is necessary for their growing base of mobile customers. As a result, Lilly Pulitzer invested in an eCommerce progressive web app and in one year, the PWA brought the company an 80% boost in mobile traffic and a 33% increase in conversions.

6. Uniqlo - SPA

Uniqlo, the leading Japenese apparel manufacturer and retailer has brought eCommerce to customers outside of its headquartered country, and is on track to be the world’s “No. 1 retailer”. Although Uniqlo has about 1,300 stores worldwide, only 50 are in the U.S., and this is by design. The eCommerce giant created a presence where there are limited physical stores to increase online traffic and conversions - a key objective for the retailer. Uniqlo US provides customers a single page application, catering to a younger, tech-savvy audience as they further their efforts to earn $10 billion in overall North American sales by 2020.


7. Wego - PWA + AMP

Wego, the travel search engine operating in 52 countries, has adopted AMP and PWA technology and has never looked back. From awareness to checkout, the entire customer journey experience has become optimized: Click-through-rates tripled; first page load time dropped to less than a second compared to a previous 12s load; bounce rates dropped 20%; and Wego nearly doubled their conversions. By building a mobile-first site (including an Add to Homescreen option and auto-fill forms), they provide their users a faster, reliable booking experience that has proven it’s worth.

8. Trivago - PWA

Trivago, one of the world’s leading hotel search engines, found that more users access their services through mobile than desktop. It became a priority for Trivago to perform on all platforms that mattered, “We’re a technology company, and we’re passionate about using the latest methods and tools to improve our services,” says Tom Dwyer, Project Lead for PWA and Front-End Developer at Trivago. In adopting a PWA site, the travel search engine has seen a 150% jump in customer engagement, and more than 500,000 people added the PWA app to their homescreens.

9. IHG Hotels - SPA

InterContinental Hotels Group, the multinational hospitality company connecting people with over 4,500 hotels, adopted an Angular SPA to improve their overall mobile performance. To create the most reliable service possible, they didn’t want their travelers struggling to find, change, or book a hotel reservation —a problem often faced when travelling in spotty network areas. Their SPA allows access to a mobile website quickly and easily, even in low bandwidth locations, so IHG reservations are never out of reach.

Bottom line

Progressive Web Apps are the future for eCommerce web experiences. In considering Amazon’s calculated $1.6 billion drop in yearly sales with a slower page-load of just one second, and Google losing 8 million searches per day from slowing its search results by just four tenths of a second — it’s certain that site speed matters.

PWAs are proven to deliver a better user experience with native-app like features. And with browsing speeds that are nearly instantaneous, users won’t leave your site frustrated and buy from your competitors.
