- +$0.62 revenue per session.
- +$36,240 per month in revenue.
- +$434,880 per year, which is a forecast, not measured revenue.
- Add-to-cart rate after the change, sample size and test length were not shared.
The change
Size boxes become clear radio buttons, with thumbnails, a reviews link and a bolder button.
Simplified mockup drawn by LiftArchive from the shared screenshots.
Control
Sizes appeared as a grid of plain outlined boxes under a size chart link. A single review card and a short icon list (free shipping, machine washable, made in the UK) sat below.
Variant
A thumbnail strip was added under the main image and a See All Reviews link was placed beside the stars. Sizes became radio-style buttons with the chosen one filled dark, and the review card gained a verified badge.
Why it likely won
Our reading of the result, not the practitioner's claim.
- a filled, clearly selected size removes doubt about what goes in the cart.
- fewer payment logos and a stronger button cut visual noise around the main action.
- thumbnails and a reviews link let shoppers check details without hunting.
Caveats: No sample size, duration or significance was shared, and the yearly figure is a forecast. The payment and button changes are described in the post but not visible in the screenshot.

How to run this test on your store
- Hypothesis
- If we make the size picker show a clear selected state, tighten the benefit copy and remove low-use payment options, then revenue per visitor will rise because shoppers hesitate less before adding to cart.
- Primary metric
- Revenue per visitor
- Guardrails
- Add-to-cart rate
- Size-related return rate
- Checkout completion by payment method
- Who should test it
- Stores selling products with many sizes, like home textiles or apparel, where add-to-cart rates are low. Check payment usage data first so you don't remove a method a key segment relies on.
Questions
How should a size selector look on a product page?
In this test, sizes switched from plain outlined boxes to radio-style buttons with the chosen size filled dark. It was part of a bundle that added $0.62 revenue per session.
Should you remove payment options from the product page?
Oliver Kenyon removed low-performing payment options as one of four changes. The post doesn't say which ones, so check your own payment data before cutting any.
What is a typical add-to-cart rate?
This store had about 10% of users adding to cart before the redesign. The post does not share the rate afterwards.
