One product per row on mobile: +63.1% RPV, inconclusive
Test run byClean CommitCRO agency
Commentary byLiftArchiveOur analysis, not theirsShowing 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.
- 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.
The change
The variant shows one large product card per row on mobile.
Simplified mockup drawn by LiftArchive from the shared screenshots.
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 of the result, not the practitioner's claim.
- 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 on your store
- 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
- Guardrails
- Orders
- Product views per session
- 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.
Questions
Should mobile collection pages show one or two products per row?
It depends on your products. One per row gives more detail per product, while two per row helps shoppers compare and browse faster.
Why treat a +63.1% revenue lift as inconclusive?
No sample size or probability was shared, and orders fell.
Big swings in order value often come from a few unusual orders.
What should I watch when testing grid layouts?
Watch orders and product views as well as revenue, so you can tell if shoppers are browsing less.
