Mobile checkout overhaul: orders doubled (+100%)
Test run byClean CommitCRO agency
Commentary byLiftArchiveOur analysis, not theirsReworking the mobile shopping and checkout flow doubled orders (+100%), even though the variant got 12.2% fewer visitors.
Clean Commit ran this test for an anonymized Shopify store and published it in its A/B test library.
Several changes shipped together, and the agency believes the original mobile checkout was close to broken, so read this as a fix rather than a typical uplift.
- Orders: +100%. Orders doubled in the variant.
- Visitors: -12.2%. The variant saw fewer visitors, which the agency thinks reflects a change in how traffic was split during the test.
- Conversion rate: the agency reports a lift too large to put a number on, which points to a control that was barely converting.
- No significance figure or sample size was shared.
The change
The variant trims the mobile form and simplifies payment, alongside speed and navigation fixes.
Simplified mockup drawn by LiftArchive from the shared screenshots.
Control
The store's original mobile browsing and checkout flow. The agency's data suggests it produced close to zero mobile conversions.
Variant
Faster mobile pages, better touch targets and product navigation, fewer checkout form fields, and a simpler payment step, all shipped as one bundle.
Why it likely won
Our reading of the result, not the practitioner's claim.
- If the original checkout was broken on mobile, almost any working flow would win by a wide margin.
- Fewer form fields and a simpler payment step cut the typing and tapping that mobile shoppers find hardest.
- Faster pages and better touch targets reduce drop-off before shoppers even reach checkout.
- Because everything changed at once, there is no way to tell which change did the most work.
Caveats: Bundled: speed, navigation, form and payment changes shipped together, so the lift can't be credited to any one of them. The control likely had near-zero mobile conversions, visitor counts were uneven, and no sample size or significance was shared.

How to run this test on your store
- Hypothesis
- If we cut mobile checkout to fewer fields and a simpler payment step, then more mobile visitors will finish their order because there is less typing and fewer chances to get stuck.
- Primary metric
- Mobile orders per visitor
- Guardrails
- Checkout error rate
- Average order value
- Page load time
- Who should test it
- Stores whose mobile conversion rate is far below desktop, especially if analytics show drop-off at a specific checkout step. If mobile already converts close to desktop, expect a much smaller gain than this one. Check the flow works on real phones before you test anything.
Questions
How much can a mobile checkout fix increase orders?
In this test orders doubled, but the original mobile flow was likely barely working.
A store with a working checkout should expect a much smaller lift.
What should I fix first in a mobile checkout?
Start with anything that blocks people outright, such as errors, broken buttons or slow pages.
Then cut form fields and offer a quicker payment option.
Why test a bundle instead of one change at a time?
When a flow is clearly broken, fixing everything at once gets the gain sooner.
The trade-off is that you won't know which change mattered most.
