Reworking 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.

## Result

**orders doubled (+100%)**

- 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.

## 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)

- 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

- 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
- Guardrail: Checkout error rate
- Guardrail: Average order value
- Guardrail: 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.
