- Outcome: Flat / inconclusive
- Page type: Cart (Ecommerce)

Redesigning the main button in the mobile mini-cart lifted conversion rate 4.7%, but with only 1,215 visitors the result is not statistically significant. Clean Commit ran this test for an anonymized Shopify store and published it in its A/B test library. The agency calls it a positive signal; we count it as inconclusive.

## Result

**+4.7% conversion, not significant**

- Conversion rate: +4.7%, with a 76.9% probability of beating the original. Inconclusive: not statistically significant.
- Orders: +5.9%.
- Revenue per visitor: +4.6%.
- Average order value: -0.1%, essentially flat, so any gain came from more orders rather than bigger ones.

## Control

The mobile mini-cart showed the store's original main call-to-action button.

## Variant

The main button in the mobile mini-cart got a new design. The test ran on mobile visitors only.

## Why it likely came out this way (our reading)

- A clearer, more prominent button may make the next step to checkout easier to spot on a small screen.
- The mini-cart is a short step from purchase, so a small button change can only move things so much.
- With 1,215 visitors, a lift of this size is well within what chance alone can produce.

## Caveats

Very small sample: 1,215 mobile visitors, with a 76.9% probability to win. The result is directional only, and the source does not describe the exact design change.

## How to run this test

- Hypothesis: If we make the main mini-cart button on mobile clearer and more prominent, then more shoppers will go on to buy because the path to checkout is easier to see.
- Primary metric: Mobile conversion rate
- Guardrail: Average order value
- Guardrail: Cart abandonment rate
- Who should test it: Stores that use a slide-out mini-cart on mobile and see many shoppers open it without checking out. You need far more than 1,215 visitors to confirm a lift of about 5%, so plan for a longer run.
