Test run byBlend CommerceCRO agency
Commentary byLiftArchiveOur analysis, not theirsPlacing a positive, product-specific customer review near the top of the product page lifted revenue per visitor by 4% for Azuna.
Blend Commerce ran this A/B test. The gains were small but showed up across conversion, add to cart and order value.
- Revenue per visitor: +4%.
- Conversion rate: +1.34%, and add-to-cart rate: +2%.
- Average order value: +2.5%.
- Subscription revenue per visitor: +1.32%. All lifts are small.
The change
A single positive review moves up next to the buy button.
Simplified mockup drawn by LiftArchive from the shared screenshots.
Control
Reviews appeared only at the bottom of the product page. Heatmaps showed few shoppers scrolled that far.
Variant
One positive review about the product's results was placed near the top of the page, close to the buy button.
Why it likely won
Our reading of the result, not the practitioner's claim.
- Most shoppers never reached the reviews, so moving one up put proof in front of far more people.
- An odour eliminator has to work, so a review about results answers the main doubt right at the buy button.
- Seeing proof earlier may make shoppers more willing to buy a larger size or more units.
Caveats: The lifts were small and no significance level, sample size or duration was shared, so the result may be within normal noise.

How to run this test on your store
- Hypothesis
- If we place a positive, product-specific review near the buy button, then revenue per visitor will rise because shoppers see proof before they decide.
- Primary metric
- Revenue per visitor
- Guardrails
- Conversion rate
- Add-to-cart rate
- Review section engagement
- Who should test it
- Stores selling products whose main doubt is whether they work, with reviews buried low on the page. If reviews already show near the top, expect little gain.
