Showing one product card per row on mobile collection pages, instead of several, lifted revenue per visitor 63.1%, driven by a 58.3% rise in average order value. Clean Commit ran this test for an anonymized Shopify store and published it in its A/B test library. We count it as inconclusive: no sample or probability was given, and orders fell.

## Result

**+63.1% RPV, inconclusive**

- Revenue per visitor: +63.1%, the target metric. No significance was reported.
- Average order value: +58.3%, which drove most of the revenue gain.
- Conversion rate: +3.0%, a small move.
- Orders and visitors fell, a negative signal. The size of the drop was not shared.

## Control

A mobile collection grid showing several product cards per row.

## Variant

A single-column mobile grid with one larger product card per row.

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

- Larger cards show products in more detail, which may help shoppers judge them.
- A jump in order value this big from a layout change is unusual, so a few large orders may have skewed the result.
- One card per row means more scrolling, so shoppers see fewer products, which may explain fewer orders.

## Caveats

No sample size, duration or probability was shared, and orders fell. A large AOV swing like this can come from a few big orders.

## How to run this test

- Hypothesis: If we show one product card per row on mobile collection pages, then revenue per visitor will rise because shoppers can see each product more clearly.
- Primary metric: Revenue per visitor
- Guardrail: Orders
- Guardrail: Product views per session
- Guardrail: Collection page scroll depth
- Who should test it: Stores with visual products where detail sells, such as apparel or home goods. Stores with big catalogs where shoppers browse many items may lose out from the extra scrolling.
