Designing Mobile Stores: Elements That Determine Conversion
Over 25 million Poles use smartphones. According to the latest data, smartphones already account for 64.05% share of the Polish e-commerce market in 2024, and their share will continue to grow. These statistics clearly show that Mobile-First is no longer a trend today, but the foundation for designing the User Experience (UX) of online stores.
Mobile-First is no longer a trend today, but the foundation for designing the User Experience (UX) of online stores.
In this article, we will discuss three key aspects of mobile store design that directly affect the conversion rate, and show how the implementation of PWA and native payment solutions eliminates the most common obstacles on the customer path.

What Really Scares Mobile Customers Away and How to Combat It
Success in mobile e-commerce depends on eliminating difficulties in the purchasing process. Consumer studies clearly indicate that the factors most effectively reducing conversion are no longer just a matter of aesthetics, but of fundamental performance and convenience.
1. Performance: The Fight Against Slow Loading (PWA and Core Web Vitals)
Slow-loading pages are the main reason for abandoning purchases today. Every second of delay drastically reduces conversion because the potential customer values convenience the most, and convenience means an almost instantaneously operating application or website. Traditional architectures often fail to meet Google's Core Web Vitals requirements.
The solution? PWA (Progressive Web Apps), which separate the front-end layer from the back-end, are a standout trend. Thanks to this, they provide unprecedented page loading speed (often below 1 second) and a full-screen experience, eliminating customer frustration and increasing engagement rates.
3. Navigation and Content: UX Modeled on Native Applications
Mismatching content to small screens and an overwhelming flood of information make the user feel lost. The classic "hamburger" menu and miniature links are mobile UX traps.
The solution? Designing mobile store views should be based on patterns known from native applications – minimalism, intuitive bottom bar navigation (Tab Bar), and emphasizing elements related to the purchase path (the "add to cart" button must be immediately visible and clickable). The goal: simplicity and full focus on conversion.
Summary: Mobile-First is Architecture, Not Just UX
As you can see, the era of "adapting" the desktop view to small screens is irrevocably over. A high cart abandonment rate and low conversion on mobile devices are direct consequences of ignoring fundamental problems: loading speed, a cumbersome checkout process, and outdated payment methods.
All the above objections can be easily overcome by using Headless Commerce technology and good Mobile UX practices. Headless Commerce, by separating the front-end from the back-end, enables the implementation of PWA (Progressive Web Apps), which solve the problem of speed and Core Web Vitals performance. This provides the flexibility necessary to implement native payments and apply intuitive, native navigation schemes that do not overwhelm the user. Investing in mobile-first UX and modern architecture is today the only way to increase conversion rates and lower operating costs.
