DRIP Agency ran this test for the recovery and wellness brand and published it as a case study.
The agency reports €60.5K of extra revenue during the test.
- Revenue per user: +5.5% on the targeted product pages.
- Extra revenue: about €60.5K during the test runtime. This is not a monthly or yearly figure.
- Sample size, duration and confidence level were not shared.
The change
Scattered trust cues grouped into one promise section with trial, warranty and free returns
Simplified mockup drawn by LiftArchive from the shared screenshots.
Control
Trust cues like the trial, warranty and free returns were scattered across the page. Shoppers had to find them one by one.
Variant
A clear section titled 'Unser Versprechen' (Our promise) grouped the 90-day risk-free trial, the warranty and free shipping and returns in one place.
Why it likely won
Our reading of the result, not the practitioner's claim.
- Premium recovery products feel like a risk to buy. One clear block of guarantees lowers that risk.
- Grouping the promises makes them easier to notice than scattered small icons.
- DRIP's research found that the 90-day trial helped buyers justify the premium price.
Caveats: Ran on selected product pages 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 on your store
- Hypothesis
- If we gather our trial, warranty and free returns into one visible promise section, then revenue per user will rise because buyers feel the purchase is low risk.
- Primary metric
- Revenue per user on product pages
- Guardrails
- Conversion rate
- Return rate
- Add-to-cart rate
- Who should test it
- Stores selling premium or considered products that already offer strong guarantees but show them in small or scattered spots. It won't help much if your policies are weak or standard for the category.
Questions
Does showing a guarantee increase sales?
It often helps for premium products. In this test a grouped promise section lifted revenue per user by 5.5%.
Will a risk-free trial increase returns?
It can, so watch your return rate during the test.
The goal is more net revenue after returns, not just more orders.
Where should a guarantee section go on a product page?
Close to the buying decision, near the price and button, so it is seen before shoppers decide.
