The variant turns the money-back guarantee into a more prominent block.

Simplified mockup drawn by LiftArchive from the shared screenshots.

Control

The page showed the brand's existing money-back guarantee in its usual, less prominent form.

Variant

The guarantee became a more prominent block, meant to reduce the feeling of risk before buying.

Why it likely lost

Our reading of the result, not the practitioner's claim.

  • A large guarantee block can make shoppers think about failure. It may suggest the product often doesn't work, which raises doubt instead of lowering it.
  • The product page was already long, so another big block may have added clutter and pushed key content down.
  • DRIP's next step was shorter trust cues, which suggests the size of the block, not the guarantee itself, was the issue. That is our reading.

Caveats: Significance and sample size were not shared, and the page type was not stated. The loss was enough for the team to stop the test.

How to run this test on your store

Hypothesis
If we make the money-back guarantee more prominent, then purchases will rise because shoppers feel less risk. Test it against a short trust line too, since a big block can backfire.
Primary metric
Purchases (conversion rate)
Guardrails
  • Revenue per visitor
  • Return or refund rate
  • Add-to-cart rate
Who should test it
Brands selling products where results are uncertain, such as beauty, health or devices. Try a short guarantee line near the buy button before a big block. Be careful if the guarantee already shows clearly, since this test shows more emphasis can hurt.

Questions

Can a money-back guarantee hurt conversions?

Yes. In this test a more prominent guarantee cut purchases 9.2%.

Too much focus on refunds can make shoppers think about the product failing.

Where should a guarantee go on a product page?

A short line near the buy button is a common start.

Test any bigger block against it rather than assuming more emphasis helps.

Why do some trust signals lower sales?

They can raise a worry the shopper didn't have, or add clutter.

Trust cues work best when they are short and answer a real concern.
