Prominent star ratings and review counts on cards: +$31,287/month
Test run byConvertiblesCRO agency
Commentary byLiftArchiveOur analysis, not theirsShowing 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.
- 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.
The change
Each product card adds a large star rating and review count line.
Simplified mockup drawn by LiftArchive from the shared screenshots.
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 of the result, not the practitioner's claim.
- 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 on your store
- 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
- Guardrails
- Click-through from collection to product pages
- Conversion rate
- 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.
Questions
Should collection page cards show review counts or just stars?
In this test, stars alone did not win.
The version that paired the rating with the number of reviews, shown prominently, came out on top.
What if some products have very few reviews?
A strong rating from three reviews can look thin.
Consider showing ratings only above a minimum count, or using a different badge for newer products.
Can review stars make product cards look cluttered?
They can if they compete with the image or price.
Keep the rating visible but secondary to the product photo.
