Mobile UX is still the most overlooked area in Shopify stores.

Despite the majority of traffic coming from mobile devices, many stores are still designed and evaluated primarily on desktop.

In audits, I consistently come across the same issues:

• No persistent (sticky) Add-to-Cart on product pages • Overly long, unstructured product content that’s difficult to scan • Key information placed too far down the page • CTA buttons positioned outside natural thumb reach

Mobile is not simply a scaled-down version of desktop. It reflects a different user behavior altogether faster browsing, shorter attention spans, and a much lower tolerance for friction.

Users on mobile:

Scroll quickly

Make decisions faster

Exit just as quickly if something feels off

A store that performs “well enough” on desktop can still underperform significantly on mobile.

One practical exercise I often recommend: Review your entire store experience exclusively on your phone navigation, product pages, and checkout flow.

The gaps become obvious very quickly.

When was the last time you evaluated your store purely from a mobile user’s perspective?
