Test run byBlend CommerceCRO agency
Commentary byLiftArchiveOur analysis, not theirsAdding three trust-building lines under the Add to Cart button raised conversion rate by 13.5% for casket retailer Titan Casket.
Blend Commerce ran this two-week A/B test on the product page.
Add-to-cart rate rose 34.5% and revenue per visitor rose 39.8%.
- Conversion rate: +13.5% overall.
- Add-to-cart rate: +34.5%, so more shoppers moved from browsing to buying.
- Revenue per visitor: +39.8%, the biggest overall gain.
- Mobile led the way: +32.7% conversion, +47.7% add-to-cart rate and +105.2% revenue per visitor. Desktop conversion rose a smaller 5.8%.
The change
Three trust lines added directly below the Add to Cart button.
Simplified mockup drawn by LiftArchive from the shared screenshots.
Control
The product page had no value propositions near the Add to Cart button.
Variant
Three lines sat below the button: "Chosen by over 20,000 families & 500+ funeral directors", "Hundreds of deliveries per week to all 50 states" and "Rated 4.93/5 by thousands of families".
Why it likely won
Our reading of the result, not the practitioner's claim.
- Buying a casket online is a high-stakes, unfamiliar purchase. Proof that thousands of families and funeral directors chose the brand eases that worry.
- The delivery line answers a practical fear: will it arrive in time, wherever the family lives?
- Placing the proof right at the button puts it where the buying decision happens, not further down the page.
- On mobile, trust content lower on the page is easy to miss, which may explain the bigger mobile lift. This is our reading, not the source's.
Caveats: The test ran for two weeks. 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 add short trust lines (customer count, delivery reach, rating) below the Add to Cart button, then more shoppers will buy because their doubts are answered at the moment of decision.
- Primary metric
- Conversion rate
- Guardrails
- Revenue per visitor
- Add-to-cart rate
- Return or cancellation rate
- Who should test it
- Stores selling high-value or unfamiliar products where trust is a barrier, especially with lots of mobile traffic. It will likely do less for well-known brands, or if the claims are vague or can't be backed up.
Questions
What should go below the Add to Cart button?
Short, specific proof points work well: how many customers you've served, where you deliver and your average rating.
In this test, three such lines lifted conversion by 13.5%.
Do trust badges work better on mobile?
Here they did. Mobile conversion rose 32.7% against 5.8% on desktop, though the source did not share sample sizes for each device.
How many value propositions should I show?
This test used three. Keep each one short and concrete so shoppers can scan them without slowing down.
