Moving a one-click cross-sell from low on the page into the buy box, above the Add to Cart button, raised revenue per user by 3.0% 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 €29.8K of extra revenue during the test.

## Result

**+3.0% revenue per user**

- Revenue per user: +3.0%.
- Extra revenue: about €29.8K during the test runtime. This is not a monthly or yearly figure.
- The case study does not say how often the add-on was picked or how conversion rate moved.
- Sample size, duration and confidence level were not shared.

## Control

A complementary product appeared low in the page content, below the fold. Many shoppers likely never scrolled to it.

## Variant

A compact one-click cross-sell for the same kind of add-on was moved into the buy box, just above Add to Cart.

## Why it likely won (our reading)

- The add-on shows up at the exact moment the shopper decides what to buy, not after.
- One click to add keeps effort low, so it doesn't slow the main purchase.
- A relevant add-on can feel helpful when products are made to work together.

## Caveats

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

## How to run this test

- Hypothesis: If we move a relevant one-click add-on into the buy box above Add to Cart, then revenue per user will rise because shoppers see it while deciding what goes in the order.
- Primary metric: Revenue per user
- Guardrail: Conversion rate
- Guardrail: Add-to-cart rate for the main product
- Guardrail: Return rate
- Who should test it: Stores with a clear companion product that suits most buyers, like a cover for a pillow or a case for a device. It can backfire if the add-on is not relevant or crowds the buy box and distracts from the main product.
