A simpler, mobile-first cart with bigger buttons and one main call to action lifted SMITH's mobile visits to checkout by 8%. Returning mobile visitors moved to checkout 10% more often. Surefoot ran this A/B test for SMITH and published it as a case study; it also appeared as a Convert.com case study.

## Result

**+8% visits to checkout**

- Visits to checkout on mobile: up 8%, at 95% statistical significance.
- Returning mobile visitors: 10% more reached checkout.
- Transactions: up 3.4%, and revenue per visitor up $1.39, according to the Convert.com version of the case study.
- Both full-price shoppers and pro-deal subscribers saw a lift, with the largest revenue gain from full-price buyers.

## Control

A busy mobile cart with unclear calls to action and small tap targets. It also had display bugs on common phones.

## Variant

A mobile-first cart with larger buttons and tap targets, a simpler layout, login at the top and easier cart editing. One primary call to action sat at the bottom.

## Why it likely won (our reading)

- Bigger tap targets and one clear next step make the cart easier to use on a small screen.
- Moving login to the top helped returning shoppers, who could sign in without scrolling past the whole cart. That fits their bigger lift.
- Fixing the display bugs means some visitors could use the cart properly for the first time.

## Caveats

Several cart changes shipped together, including bug fixes, so the lift can't be credited to one element. Sample size and duration were not shared, and the transaction and revenue figures come from the Convert.com version.

## How to run this test

- Hypothesis: If we simplify our mobile cart with larger tap targets, login at the top and one primary checkout button, then more mobile shoppers will reach checkout because the next step is clear and easy to tap.
- Primary metric: Mobile visits to checkout
- Guardrail: Mobile transactions
- Guardrail: Revenue per visitor
- Guardrail: Cart edits and removals
- Who should test it: Stores with mostly mobile traffic and a cart built for desktop first, or one with many competing buttons. Stores that already have a clean mobile cart will probably see smaller gains.
