Money-back guarantee badge below add to cart: +30.33% desktop sales
Test run byBlend CommerceCRO agency
Commentary byLiftArchiveOur analysis, not theirsAdding 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.
- 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.
The change
A money-back guarantee badge added directly under the add-to-cart button.
Simplified mockup drawn by LiftArchive from the shared screenshots.
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 of the result, not the practitioner's claim.
- 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 on your store
- 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
- Guardrails
- Refund and return rate
- Mobile conversion rate
- 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.
Questions
Where should a money-back guarantee go on a product page?
Right next to the buy button is a common choice, because that is where doubt peaks.
In this test, placing it below add to cart lifted desktop conversion by 30.33%.
Why would a guarantee badge work on desktop but not on mobile?
Space is tight on mobile, so an extra badge can push key content further down or add clutter.
Always read results by device before shipping a change everywhere.
Does showing a guarantee increase refunds?
It can, so track refund rate alongside conversion.
The source for this test did not report refund data.
