Swipeable images on collection cards: +€96,350 revenue lift
Test run byKasper DolkMaison Commerce
Commentary byLiftArchiveOur analysis, not theirsLetting shoppers swipe through several images on collection page product cards showed a +€96,350 revenue lift at 97% confidence. Kasper Dolk ran this test, alongside a second one adding a retail price comparison popup on the product page (+€30,554 at 94%). Both tests were still running when the results were shared.
- Swipeable collection images: +€96,350 revenue lift across 10,796 unique visitors, at 97% confidence. The testing tool marked it significant.
- Retail price comparison popup: +€30,554 revenue lift across 6,302 unique visitors, at 94% confidence. Also marked significant, though just under the common 95% bar.
- Conversion rate, revenue per visitor and order value were not shared for either test, so we can't say where the extra revenue came from.
- It is not clear whether the revenue lift figures are measured gains or the tool's monthly projections.
The change
The variant lets shoppers swipe through product images on each collection card.
Simplified mockup drawn by LiftArchive from the shared screenshots.
Control
Collection page product cards showing a single image each, so seeing more photos meant clicking into the product page.
Variant
Product cards that let shoppers swipe through multiple product images right on the collection page. The second test added a popup on the product page comparing the store's price with a retail price; its design was not shown.
Why it likely won
Our reading of the result, not the practitioner's claim.
- extra photos on the card let shoppers judge a product without a click, so more of them reach a product they actually want.
- a retail price comparison frames the store's price as a saving, which can make the purchase feel safer.
- both changes give shoppers information earlier in the journey, which tends to cut wasted clicks and doubt.
Caveats: Both tests were still running, having started about a week before the post, and only revenue lift, visitors and confidence were shown. Results come from a single client store.

How to run this test on your store
- Hypothesis
- If we let shoppers swipe through product images on collection cards, then more of them will buy because they can judge products without opening each one.
- Primary metric
- Revenue per visitor
- Guardrails
- Collection page load time
- Click-through rate to product pages
- Average order value
- Who should test it
- Visual categories like fashion, home goods and accessories, where several angles help shoppers decide, especially with mostly mobile traffic. It will matter less for stores with few products or items that look the same from every angle.
Questions
Should collection page product cards show multiple images?
In Kasper Dolk's test, swipeable card images showed a +€96,350 revenue lift at 97% confidence across 10,796 visitors. The test was still running, so treat it as a strong early signal.
Does showing a retail price comparison increase sales?
A product page popup comparing the store's price with retail showed a +€30,554 revenue lift at 94% confidence. That is just below the usual 95% threshold, and the test was still running.
Do swipeable images slow down collection pages?
The post doesn't say. Loading extra images per card can add weight, so keep page speed as a guardrail when you test it.
