Test run byOliver KenyonConversionwise
Commentary byLiftArchiveOur analysis, not theirsMoving the star rating under the product name, along with a moved discount badge, a sticky add-to-cart button and clickable thumbnails, raised revenue per session by $0.539. Oliver Kenyon ran this test on a product page. Their team estimated $38,846 a month in extra revenue.
- Revenue per session: up $0.539 per session. The post does not give the baseline, so the percentage lift is unknown.
- Monthly revenue: about $38,846 extra, based on the team's forecast.
- Yearly revenue: about $466,152, also a forecast, not money already banked.
- Conversion rate and average order value were not shared.
The change
Rating moves under the title, the gallery gets thumbnails, and add to cart becomes sticky.
Simplified mockup drawn by LiftArchive from the shared screenshots.
Control
The rating (4.7 from 55,633 reviews) sat low on the page, below the guarantee. The gallery used dots, and the savings note sat in small text under the add-to-cart button.
Variant
The rating moved directly under the product name and a savings badge was made more visible. The gallery gained clickable thumbnails and arrows, and the add-to-cart button stayed on screen while scrolling.
Why it likely won
Our reading of the result, not the practitioner's claim.
- a high rating from a large number of reviews is strong proof, and it works harder near the top of the page.
- a sticky add-to-cart button removes the need to scroll back up once a shopper decides.
- thumbnails show there are more images, which dots hide. Kenyon says heatmaps guided this change.
Caveats: Four changes shipped together, so we can't tell which one did the work. Sample size, test length and the base revenue per session were not shared, and the yearly figure is a forecast.

How to run this test on your store
- Hypothesis
- If we place the star rating under the product name and keep add to cart visible while scrolling, then revenue per session will rise because shoppers see proof early and can buy at any point.
- Primary metric
- Revenue per session
- Guardrails
- Conversion rate
- Average order value
- Mobile bounce rate
- Who should test it
- Stores with a strong rating and lots of reviews that currently sit below the fold, especially with mostly mobile traffic. If you have few reviews or a weak score, moving them up may not help.
Questions
Where should star ratings go on a product page?
In this test the rating moved from below the guarantee to just under the product name. That change was part of a package that raised revenue per session by $0.539.
Does a sticky add to cart button help on mobile?
It was one of four changes in this winning test. Because they shipped together, the sticky button's own effect is not known.
Are thumbnails better than dots in a product gallery?
Kenyon's team switched to clickable thumbnails based on heatmap data. Thumbnails show what other images exist, while dots do not.
