Showing star ratings and review counts on their own line, in larger text, on every collection page card added about $31,287 a month in revenue. Convertibles ran this A/B/n test for an 8-figure adult wellness brand and published it as a Convertibles case study. A stars-only version and smaller, inline formats also ran and did not win.

## Result

**+$31,287/month**

- Monthly revenue: about +$31,287 for the winning prominent format, as reported by the agency.
- Stars with counts shown inline, at moderate size, did not win.
- Stars without review counts, in normal and smaller formats, did not win either.
- Conversion rate, order value, sample size and confidence were not shared.

## Control

Collection page product cards showed a bestseller badge, image, name, category label, description, colour swatches and an add-to-cart button with the price. There were no star ratings or review counts.

## Variant

Each card added the star rating and the review count, for example "4.8 (729 REVIEWS)", on a separate line in larger text. The same information also ran inline at normal size, and two other versions showed stars without the count.

## Why it likely won (our reading)

- A rating backed by hundreds of reviews is more convincing than a score alone, so the count likely did real work.
- Bigger text on its own line is hard to miss while scanning a grid, so more shoppers saw the proof.
- In an intimate category, seeing that many people bought and reviewed a product may make the purchase feel more normal.
- Products lower in the grid could stand out on their review numbers, not just their position.

## Caveats

The revenue gain is reported by the agency that ran the test. Sample size, duration and statistical confidence were not shared.

## How to run this test

- Hypothesis: If we show star ratings with review counts prominently on collection page cards, then revenue will rise because shoppers see proof of quality before clicking into a product.
- Primary metric: Revenue per visitor
- Guardrail: Click-through from collection to product pages
- Guardrail: Conversion rate
- Guardrail: Average order value
- Who should test it: Stores with healthy review volumes on most products, especially in trust-sensitive or considered-purchase categories. It is less useful if many products have only a handful of reviews, since a low count can hurt trust.
