Adding a rotating customer review carousel to product pages lifted conversion rate by 4.21% for an apparel brand. Blend Commerce ran this two-week A/B test, and revenue per visitor rose 8.77%. Significance reached only 82%, so treat the result as promising rather than proven.

## Result

**+4.21% conversion rate**

- Conversion rate: +4.21%.
- Revenue per visitor: +8.77%, so shoppers spent more as well as buying more often.
- Average products per visitor: +7.41%, a sign of larger baskets.
- The agency also reported more add-to-cart clicks and checkout visits, and a slight drop in bounce rate. Exact figures were not shared.

## Control

The original product page, with no review carousel.

## Variant

A rotating carousel of customer reviews, built with the Judge.me app, was added to the product pages.

## Why it likely won (our reading)

- Real customer reviews near the buying decision may have eased doubts about fit and quality.
- A carousel shows several reviews in a small space, so shoppers see a wider range of experiences without scrolling.
- The agency had already seen gains from showing reviews higher on the page, and this test built on that.

## Caveats

Statistical significance was 82%, below the usual 95% threshold, and the test ran for two weeks. Sample size was not shared.

## How to run this test

- Hypothesis: If we add a rotating review carousel to product pages, then conversion will rise because shoppers see social proof before they decide.
- Primary metric: Conversion rate
- Guardrail: Revenue per visitor
- Guardrail: Page load time
- Guardrail: Bounce rate
- Who should test it: Stores with plenty of good, detailed reviews, especially in categories like apparel where fit and quality worries are common. With only a handful of reviews, a carousel may look thin and help less.
