Fixing a “Clunky” Checkout: A Mobile UI/UX & CRO Strategy
Client: An e-commerce fashion store on Shopify.
Challenges We Faced
The client’s Shopify site was responsive, but had a terrible mobile user experience (UX) that was killing sales:
High Mobile Cart Abandonment
GA4 data showed 85% of mobile users abandoned their cart.
Touch-Friendly Navigation Failure
A UI/UX Analysis with Microsoft Clarity showed users “rage clicking” on tiny, “non-thumb-friendly” checkout buttons.
Poor Font & Image Scaling
Product descriptions were in a tiny font, and images were not scaling correctly.
Low Mobile Conversion Rate
Their mobile conversion rate was 0.6%, a fraction of their desktop rate.
Confusing Checkout Flow
Mobile users were lost in multiple steps, making it hard to complete purchases and reducing sales.
Fix Your Mobile Checkout
“Is your mobile site frustrating users? Our mobile responsiveness optimization focuses on ‘thumb-friendly’ UX to stop cart abandonment.”
Our Approach – How We Solved These Challenges
UI/UX Analysis (Mobile-First)
We used Microsoft Clarity heatmaps and session recordings to watch users fail to check out. We identified that the “Apply Coupon” and “Next Step” buttons were too small.
Fluid Grid & Media Query Implementation
Our mobile website design optimization company edited the theme’s CSS (.liquid files) to create larger, “thumb-friendly” buttons (50px+) and increase the default font size.
Image & Media Optimization
We ensured all product images were responsive and scaled correctly within their containers, preventing layout shifts.
Mobile-First Indexing
We ensured all content (product details, reviews) was visible on the mobile version, not hidden, to satisfy Google’s Mobile-First Indexing guidelines.

Advice for Marketers & Brand Owners
- “Responsive” is not the same as “optimized.” Your site can look OK on mobile but be unusable.
- Touch-Friendly Navigation is critical. Buttons must be large (at least 48px) and have space around them.
- Watch your users. Tools like Microsoft Clarity are essential for mobile responsiveness services. They show you why users are bouncing.
- A good mobile web page design focuses on the checkout and cart just as much as the homepage.
Extra Factors That Made It Work
- The Clarity session recordings were the #1 insight. Seeing users “rage click” a tiny button was the proof we needed.
- Fixing the Font & Image Scaling made the site feel more professional and trustworthy.
- This was a Conversion Rate Optimization (CRO)-focused project that had a massive, direct impact on revenue.
