A taller mobile product image area with minimal arrows, dots and swipe support lifted conversion rate 4.7% and orders 4.6% across 69,560 mobile visitors. Clean Commit ran this test for an anonymized Shopify store and published it in its A/B test library. We count it as inconclusive: none of the moves were significant, and add-to-cart rate, the metric the test targeted, was flat.

## Result

**+4.7% CR, ATC flat**

- Add-to-cart rate (the target): -0.5%, with a 45.1% probability of beating the original. Flat.
- Conversion rate: +4.7%, and orders +4.6%. A positive signal, but not significant.
- Revenue per visitor: +3.2%, smaller than the conversion lift because average order value dipped 1.4%.

## Control

The store's original product image carousel on mobile.

## Variant

The image area was made taller, the controls were swapped for minimal arrows and dot indicators, and swiping between images was added.

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

- Bigger images and swipe are what mobile shoppers expect, so the change may have removed small annoyances rather than changed decisions.
- Shoppers added to cart at the same rate, so the images probably didn't change whether people wanted the product.
- The gain in orders without a gain in add-to-cart may be noise, since neither was significant.

## Caveats

Not statistically significant on any metric, and the target metric was flat. Mobile only; duration was not shared.

## How to run this test

- Hypothesis: If we make mobile product images taller and add swipe with simple controls, then add-to-cart rate will rise because shoppers can judge the product more easily.
- Primary metric: Mobile add-to-cart rate
- Guardrail: Mobile conversion rate
- Guardrail: Average order value
- Guardrail: Page load time
- Who should test it: Stores whose mobile gallery is small, hard to swipe or uses clunky controls. If your carousel already works like a standard app gallery, expect little change.
