Replacing a single-slide sleep-position carousel with a side-by-side guide on the BLACKROLL recovery pillow page lifted revenue per user by 5.4%. DRIP Agency ran this test for BLACKROLL, a German recovery and wellness brand, and published it in its own case study. The variant also cut the number of bullets and made each position's callout more direct.

## Result

**+5.4% RPU**

- Revenue per user: +5.4% against the carousel version.
- Extra revenue during the test: about EUR 15.3K. This is revenue earned while the test ran, not a yearly projection.
- Significance, sample size and test length were not shared.

## Control

The pillow product page explained sleep positions in a carousel that showed one position per slide. Shoppers had to swipe to compare side, back and stomach sleeping.

## Variant

All sleep positions sat next to each other in one view. Each had fewer bullets and a clearer callout saying how the pillow suits that position.

## Why it likely won (our reading)

- DRIP's research found fit by sleep position was a major worry for pillow buyers. Seeing every position at once answers "will this fit me?" faster.
- A carousel hides most of its content. Many shoppers never swipe past the first slide.
- Fewer bullets cut reading effort on mobile, where DRIP says about 80% of BLACKROLL traffic came from.

## Caveats

Vendor-reported result from the agency that ran the test. Revenue is for the test runtime only, and significance, sample size and duration were not stated.

## How to run this test

- Hypothesis: If we show all sleep positions side by side with short, direct callouts instead of a swipe carousel, then revenue per user will rise because shoppers can confirm the product fits them without extra effort.
- Primary metric: Revenue per user
- Guardrail: Return rate for the product
- Guardrail: Add-to-cart rate
- Guardrail: Page scroll depth on mobile
- Who should test it: Stores selling products where fit depends on the buyer's body or habits, like pillows, mattresses, shoes or braces. It matters less for products with no fit question.
