As part of our ongoing CRO retainer with Spelt, we keep a close eye on the user journey and where improvements can be made. One area stood out: the transition from cart to checkout. The existing cart page was doing its job, but we saw clear potential to make it even better… especially for mobile users.

Instead of going for multiple smaller A/B tests like we often do, we decided to take a bigger swing this time. We designed and tested a full redesign of the cart page to explore how much impact we could make with better UX, clearer communication, and a sharper mobile experience.

We focused on changes that would make the cart page more persuasive, more mobile-friendly, and more conversion-driven without losing the familiar feel for returning users. Key improvements included:

• Restructured the page layout to be more logical and streamlined, making it easier for users to process what’s next

• Placed USPs above the order summary, reinforcing value and trust early in the flow

• De-emphasized the discount code field, to reduce unnecessary coupon hunting and hesitation

• Show product image on mobile for visual verification

• Added a sticky CTA on mobile, so users could always proceed to checkout with one tap

The new version was built and A/B tested against the original to validate impact.
