Short-term (< 3 months)
Last year, I was brought in to fix a Shopify store that was hemorrhaging money on mobile. The client was pulling their hair out – they had great traffic, people were adding items to cart, but 80% of mobile users were abandoning at checkout. Sound familiar?
Here's what shocked me: everyone was telling them to "optimize the checkout form" and "reduce friction." The standard advice was working... for desktop users. But mobile? It was a disaster.
After digging into their data, I discovered something that goes against everything you'll read in checkout optimization guides. The problem wasn't their form length or payment options. It was something much more fundamental – and much easier to fix.
In this playbook, you'll learn:
Why standard checkout optimization advice fails on mobile
The two mobile-specific friction points everyone ignores
My step-by-step approach that increased mobile completion by 25%
The unexpected "friction" that actually improved conversions
Real data from a 3,000+ product store transformation

Industry Knowledge
What every ecommerce owner has been told
Walk into any conversion optimization discussion and you'll hear the same mantras repeated like gospel. The industry has created a one-size-fits-all approach to checkout optimization that sounds logical but breaks down the moment real thumbs meet real screens.
The Standard Checkout Commandments:
Minimize form fields – "Each field reduces conversion by 11%"
Single-page checkout – "Multi-step is friction"
Guest checkout – "Never force account creation"
Progress indicators – "Show users where they are"
Security badges – "Build trust with SSL certificates"
This advice exists because it works... on desktop. Desktop users have large screens, precise mouse control, and usually shop in focused environments. They can see the entire form at once, click exactly where they want, and aren't constantly interrupted.
But here's where the industry gets it wrong: mobile users aren't just desktop users with smaller screens. They're fundamentally different creatures.
Mobile shoppers are often multitasking, using thumbs instead of precise cursors, dealing with auto-rotating screens, and shopping in distracting environments. Yet most "mobile optimization" is just desktop forms made smaller.
The biggest myth? That reducing friction always improves mobile conversion. Sometimes the opposite is true – strategic friction can actually guide mobile users toward completion.
Time for a different approach based on how mobile users actually behave, not how we think they should behave.
Consider me as your business complice.
7 years of freelance experience working with SaaS and Ecommerce brands.
The client who brought me this challenge was drowning in mobile cart abandonment. They sold over 3,000 products on Shopify – everything from electronics to home goods. Great catalog, solid traffic, but their mobile checkout was a conversion killer.
When I dug into their analytics, the story was clear: desktop users completed checkout at 4.2%, but mobile users? A devastating 1.8%. With 65% of their traffic coming from mobile, this wasn't just leaving money on the table – it was setting the table on fire.
My first instinct was to follow the playbook. I reduced form fields, streamlined the layout, made buttons bigger. Classic mobile optimization 101. After two weeks of testing, we saw... virtually no improvement. Mobile completion crawled from 1.8% to 1.9%.
That's when I realized I was treating the symptoms, not the disease. So I did something most consultants won't do – I spent an entire afternoon shopping on their site using only my phone, in real-world conditions. On the subway, while walking, with notifications pinging constantly.
The "aha" moment hit me during my third attempt to complete a purchase. I kept losing my place, getting confused about shipping costs, and worst of all – my thumb kept hitting the wrong elements. The checkout wasn't just hard to use; it was designed for a completely different type of human interaction.
Two specific moments made everything click. First: I tried to edit my shipping address and accidentally hit "Place Order" instead. Second: I wanted to see my full cart contents but couldn't without scrolling back up, losing my progress.
These weren't form field problems. They were fundamental mobile user experience problems that no amount of "optimization" could fix.
Here's my playbook
What I ended up doing and the results.
Once I understood the real problem, I built a completely different approach. Instead of optimizing their existing checkout, I redesigned it specifically for thumb navigation and mobile attention patterns.
The Shipping Calculator Revolution
First breakthrough: I built a custom shipping cost estimator that lived directly on product pages. Instead of users discovering shipping costs at checkout (leading to that dreaded "shipping shock"), they could see real costs upfront. The twist? If their cart was empty, it used the current product price as the baseline.
This transparency eliminated the nasty surprise factor that killed so many mobile sessions. Users knew the total investment before ever entering checkout.
Strategic Payment Flexibility
Next, I integrated Klarna's pay-in-3 option prominently throughout the mobile experience. Here's what surprised everyone: conversion increased even among customers who paid in full. The mere presence of payment flexibility reduced purchase anxiety, especially for mobile users making quick decisions.
The SEO Hack That Changed Everything
While optimizing for conversions, I discovered an unexpected opportunity. I modified the H1 structure across all 3,000+ product pages, adding the store's main keywords before each product name. This single change – deployed across the entire catalog – became one of our biggest SEO wins.
Mobile-First Information Architecture
But the real game-changer was rethinking information flow for mobile. Instead of cramming everything into a single view, I created a mobile-optimized checkout flow that revealed information progressively:
Cart Summary – Clear view of items with easy editing
Shipping Details – With real-time cost calculation
Payment Options – Including flexible payment clearly displayed
Final Review – Everything visible before confirming
Each step was designed for thumb interaction, with touch targets sized for real human fingers, not mouse cursors.
Shipping Transparency
Show real shipping costs on product pages, not at checkout. Calculate based on location and current cart value.
Payment Psychology
Flexible payment options reduce anxiety even when customers don't use them. Display prominently on mobile.
SEO Integration
Mobile optimization work can create SEO opportunities. Small technical changes can have massive organic impact.
Progressive Disclosure
Mobile users need information in digestible chunks. Design flows that reveal complexity gradually, not all at once.
The transformation was immediate and measurable. Within two weeks of implementing the new mobile checkout flow, we saw significant improvements across all key metrics.
Conversion Rate Impact: Mobile checkout completion jumped from 1.8% to 3.2% – nearly doubling the rate. More importantly, this brought mobile performance much closer to desktop (which sat at 4.2%).
Revenue Growth: With 65% of traffic coming from mobile, this conversion improvement translated to a 35% increase in overall revenue within the first month.
Unexpected SEO Win: The H1 optimization across 3,000+ product pages started showing results within 6 weeks. Organic traffic increased by 28%, with many product pages ranking for competitive terms they'd never touched before.
User Behavior Changes: Cart abandonment emails saw higher re-engagement rates because users who reached checkout were more qualified and committed. The shipping calculator meant fewer "surprise" abandonments.
What surprised everyone was how the Klarna integration performed. Even customers who chose not to use the payment plan showed higher conversion rates when the option was visible. The psychology of choice and flexibility mattered more than the actual usage.
What I've learned and the mistakes I've made.
Sharing so you don't make them.
This project taught me that mobile optimization isn't about shrinking desktop experiences – it's about understanding fundamentally different user behaviors and designing accordingly.
Top Lessons Learned:
Test beyond best practices – Standard optimization advice can be starting points, but real solutions come from understanding your specific user behavior
Address friction where it happens – Don't wait until checkout to reveal critical information like shipping costs
Psychology matters more than features – Sometimes the option to pay differently matters more than actually using it
Small changes compound – One H1 modification across thousands of pages can transform SEO performance
Mobile users aren't desktop users with smaller screens – They need completely different interaction patterns and information architecture
Transparency beats surprise – Users prefer knowing costs upfront, even if those costs are higher than expected
Progressive disclosure works – Mobile users can handle complexity if it's revealed step-by-step rather than all at once
The biggest revelation? Sometimes adding the "right" friction (like payment flexibility or shipping calculators) actually improves conversion by building confidence and reducing uncertainty.
