Trust signals on the cart page: +11.0% conversion, lower revenue
Test run byClean CommitCRO agency
Commentary byLiftArchiveOur analysis, not theirsAdding review stars, a lifetime warranty message and a local ownership badge to the cart page showed an 11.0% lift in conversion rate.
Clean Commit ran this test for an anonymized Shopify store.
Revenue per visitor fell 23.7% at the same time, and no sample or probability was shared, so we count it as inconclusive.
- Conversion rate rose 11.0%, and orders rose 13.6%.
- Average order value fell 31.3%, a sharp drop.
- Revenue per visitor fell 23.7%. This is a negative result: more orders, but less money per visitor.
- Overall: inconclusive. The source labels it a positive signal, but shares no sample size or significance.
The change
The variant adds reviews, a warranty message and a local badge around the checkout button.
Simplified mockup drawn by LiftArchive from the shared screenshots.
Control
The cart page had no trust cues near the checkout button.
Variant
The cart showed review stars and a review snippet near the checkout button, a "Lifetime Warranty" message and a "Colorado Owned" badge.
Why it likely came out this way
Our reading of the result, not the practitioner's claim.
- Reviews and a warranty near the checkout button can calm last-second doubts, which may explain more orders.
- A local ownership badge may build credibility with shoppers who value buying from nearby brands.
- The drop in order value is unlikely to come from trust cues alone. It may reflect noise or a shift in which products were bought.
Caveats: No sample size, duration or probability was shared. Revenue per visitor and order value fell sharply even as orders rose.

How to run this test on your store
- Hypothesis
- If we show reviews, warranty info and a local badge near the cart's checkout button, then more shoppers will check out because the cues reduce last-minute doubt.
- Primary metric
- Revenue per visitor
- Guardrails
- Average order value
- Conversion rate
- Cart-to-checkout rate
- Who should test it
- Stores with strong reviews and a real warranty or local story to tell. Judge it on revenue per visitor, not just orders, and run it to a proper sample size.
Questions
Do trust signals on the cart page help?
They can lift orders, as this test suggests.
But here revenue per visitor fell 23.7%, so measure revenue as well as conversion.
Which trust signals work best in the cart?
Common choices are review stars, warranty or returns messages, and badges about where the brand is based.
Test them near the checkout button, where doubt peaks.
