About the project
Longevity Box is a UK-based wellness brand on a mission to help everyone stay younger, for longer. Built on knowledge, safety, and value, the brand provides science-backed supplements that are effective and affordable, challenging the high-price norm of longevity products.
The brand turned to Turum-burum with a request to improve the KPIs of their Shopify online store and optimize the customer journey across all funnel stages.
CRO: two UX sprints for continuous growth
2024: First collaboration under a 3-week CRO package. We conducted a comprehensive UX audit, identified 20 hypotheses across the funnel, and delivered detailed prototypes to improve the site's usability, navigation, and conversion rate.
2025: Longevity Box returned for a second UX sprint to continue optimizing the website based on updated analytics and changed user behavior patterns. This phase included 21 new hypotheses aimed at refining previous UX/UI changes, further boosting performance, and improving usability for gaining competitive advantage.
Engaging homepage that converts
2024: We added and placed product sections earlier on the homepage to boost engagement, and introduced starter guidance to help new users navigate product choices with ease.
2025: We recommended emphasizing “Bundle and Save” deals to increase AOV, adding more clickable banners for broader appeal, and linking reviews to specific products to build trust and aid discovery.
2024: We recommended fixing the mobile header to make navigation easier and separating product categories from informational sections for better clarity.
2025: We recommended improving desktop navigation by aligning dropdowns, adding a visible cart counter, and reorganizing menus by user goals.
Clear & user-friendly product pages
2024: We organized product details into distinct sections and fixed the “Buy” button for consistent visibility.
2025: We recommended including clear pack duration information to support buying decisions and encourage multi-pack purchases.
Simplified & streamlined cart
2024: We cleaned up the cart layout, adjusted hierarchy for better guidance, and made mobile interactions smoother by reducing obstructions.
2025: We unified the cart experience into a single popup, simplified the color palette for better focus, and redesigned subscription selection as a dropdown.
2024: We renamed the “Quick Add” button as the “Add to Cart” for clarity, redesigned product cards for better readability, and added filtering options to help users find the right product faster.
2025: We improved mobile browsing with wider product cards in a two-column layout, redesigned filters as a pop-up, and added a product selection tool based on user health goals.
Results that matter
After the first UX sprint, Longevity Box saw a clear increase in engagement, conversions, and overall site performance, including a 39% boost in conversion rate and longer average session durations. Mobile users, in particular, spent more time on the site and generated 58% more conversions. That success led to a second collaboration in 2025. We re-evaluated user behavior, checked and refined previous improvements, and introduced new features to keep the brand competitive.
We continue our partnership, fine-tuning the interface to meet evolving user needs. So, to be continued…
