Test run byBlend CommerceCRO agency
Commentary byLiftArchiveOur analysis, not theirsPlacing one featured customer review near the main buying area of the product page lifted revenue per visitor by 39% for a Shopify brand.
Blend Commerce ran this test. Average order value rose 29% and conversion rate 7%, with most of the gain on desktop.
- Revenue per visitor: +39%, the primary metric.
- Average order value: +29%, the main driver of the revenue gain.
- Conversion rate: +7% overall.
- Add-to-cart rate fell slightly, and mobile conversion and add-to-cart both declined, though mobile revenue per visitor still rose.
The change
One featured customer review is added near the buying area.
Simplified mockup drawn by LiftArchive from the shared screenshots.
Control
The original product page kept customer reviews further down, away from the buying area.
Variant
One customer review was featured prominently near the price and add-to-cart area.
Why it likely won
Our reading of the result, not the practitioner's claim.
- A review at the point of decision answers doubts while the shopper is choosing.
- Social proof may have made shoppers more confident in higher-value options, lifting order value.
- Fewer add-to-carts but more revenue suggests the review filtered out low-intent shoppers.
Caveats: Gains came mainly from desktop; mobile results were mixed and add-to-cart fell slightly. The source does not share sample size, duration or confidence.

How to run this test on your store
- Hypothesis
- If we feature one strong customer review next to the buy box, then revenue per visitor will rise, because shoppers see proof at the moment they decide.
- Primary metric
- Revenue per visitor
- Guardrails
- Add-to-cart rate
- Mobile conversion rate
- Average order value
- Who should test it
- Stores selling considered or higher-priced products where trust matters, and that have reviews that speak to common doubts. It may do little for cheap impulse items, and check mobile on its own.
Questions
Where should reviews go on a product page?
Testing one review near the buy box is a good start.
In this test it raised revenue per visitor by 39%, mostly on desktop.
Can a featured review lower add-to-cart rate?
It did slightly here. Revenue still rose, which suggests the shoppers who added to cart were more likely to buy and spent more.
