Adding a money-back guarantee badge below the add-to-cart button raised desktop conversion rate by 30.33% for a health brand. Blend Commerce ran this two-week A/B test. The badge underperformed on mobile, so it was only made permanent on desktop.

## Result

**+30.33% desktop sales**

- Desktop conversion rate: +30.33%.
- Desktop revenue: +20.03%.
- Desktop add-to-cart rate: +2%, a small change compared with the conversion lift.
- Mobile: the badge underperformed. The source gives no mobile numbers, and the variant was shipped on desktop only.

## Control

The product page did not mention the brand's money-back guarantee, even though the brand offered one.

## Variant

A badge reading 'No Reaction Money Back Guarantee' was placed directly below the add-to-cart button.

## Why it likely won (our reading)

- A guarantee next to the buy button answers a key worry for health products: what if it doesn't agree with me?
- The guarantee already existed but was hidden, so the test only made an existing promise visible.
- On mobile, the badge may have pushed other content down or added clutter. The agency checked whether people mistook it for a button, but clicks on it were low.

## Caveats

The test ran for two weeks and the gain applies to desktop only; mobile results were worse. Sample size and confidence level were not shared, and results are reported by the agency.

## How to run this test

- Hypothesis: If we show our money-back guarantee directly below the add-to-cart button, then more visitors will buy because the risk of a bad experience feels lower.
- Primary metric: Conversion rate, split by device
- Guardrail: Refund and return rate
- Guardrail: Mobile conversion rate
- Guardrail: Add-to-cart rate
- Who should test it: Brands that already offer a guarantee but don't show it on product pages, especially for products people worry about, like supplements or skincare. Check mobile results separately, as this test lost there.
