Vertical six-product recommendations on product pages: +2.6% AOV
Test run byVisuallyTesting and CRO tool
Commentary byLiftArchiveOur analysis, not theirsThe Oodie replaced a horizontal recommendation slider on product pages with a vertical mini-collection of six products, and average order value went up 2.6%.
Visually ran this test for the loungewear brand and published it as a case study. Sample size and significance were not shared.
- Average order value: +2.6% for the vertical six-product layout.
- No conversion rate or revenue per visitor figures were shared, so the effect on total revenue is unknown.
- Sample size and statistical confidence were not reported.
The change
A two-product slider becomes a vertical list of six recommendations.
Simplified mockup drawn by LiftArchive from the shared screenshots.
Control
Product pages showed recommended products in a horizontal slider, two products at a time. Shoppers had to swipe or click to see more.
Variant
The slider was replaced with a vertical mini-collection that showed six products at once, with no swiping needed.
Why it likely won
Our reading of the result, not the practitioner's claim.
- Six products in view means shoppers see three times as many options without any effort.
- Sliders hide most of their content. Many shoppers never swipe past the first cards.
- A vertical list reads like a small collection page, which may invite browsing and adding a second item.
Caveats: Vendor-reported result from a Visually case study. Sample size, test length and significance were not shared.

How to run this test on your store
- Hypothesis
- If we show recommendations as a vertical list of six products instead of a two-at-a-time slider, then average order value will rise because shoppers will see more add-on options without swiping.
- Primary metric
- Average order value
- Guardrails
- Conversion rate
- Add-to-cart rate on the main product
- Page load time on mobile
- Who should test it
- Stores with a wide catalog where shoppers often buy more than one item, such as apparel and home goods. It is less likely to help stores with a small catalog or a single hero product.
Questions
Are carousels bad for product recommendations?
Not always, but most shoppers only see the first few cards in a carousel.
Showing more products at once often gets more of them seen.
How many recommended products should a product page show?
There is no fixed number. This test found six in a vertical list beat two in a slider on order value, but you should test what fits your page length and catalog.
Should I measure recommendation tests on AOV or conversion rate?
Track both. A layout can lift order value while hurting conversion, so revenue per visitor is the safest overall check.
