Adding a compact, collapsible benefits accordion to the mobile buy box raised revenue per user by 4.2% on BLACKROLL's Recovery Pillow product page. DRIP Agency ran this test for the recovery and wellness brand and published it as a case study. The agency reports €21.5K of extra revenue during the test.

## Result

**+4.2% revenue per user**

- Revenue per user: +4.2% on mobile.
- Extra revenue: about €21.5K during the test runtime. This is not a monthly or yearly figure.
- Sample size, duration and confidence level were not shared.

## Control

The mobile product page used the standard buy box. Key benefits were not grouped near the price and button.

## Variant

A compact accordion of the strongest benefits was placed inside the buy box, near the price and Add to Cart. Shoppers could expand it without leaving the decision area.

## Why it likely won (our reading)

- Buyers of a premium pillow want to know it will ease pain and help sleep. Showing those benefits next to the price supports the decision at the right moment.
- Collapsing the list keeps the mobile buy box short, so the button stays easy to reach.
- Grouping benefits into small chunks makes them easier to scan on a phone.

## Caveats

Mobile only. The revenue figure covers the test runtime, which was not stated, and significance and sample size were not shared.

## How to run this test

- Hypothesis: If we add a collapsible list of key benefits inside the mobile buy box, then revenue per user will rise because shoppers see why the product is worth it right before they decide.
- Primary metric: Revenue per user on mobile
- Guardrail: Add-to-cart rate
- Guardrail: Conversion rate
- Guardrail: Accordion open rate
- Who should test it: Stores selling premium products where shoppers need reassurance before paying more, especially with mostly mobile traffic. It matters less for cheap, familiar items where people buy without reading.
