Client stories
Specific engagements — what was measured, what constrained the work, and what the briefing changed.
“The lift study on our PDP add-ons took longer than we hoped because category tags were inconsistent — WillowCore flagged that early instead of burying it. Once cleaned, the attach-rate chart for home textiles was the one slide our buyers kept.”Priya N., digital merchandising lead, homeware retailer
“We already knew the campaign ‘worked’ in a vague sense. The visualisation briefing forced us to separate gift-with-purchase noise from true cross-sell attach. Mild gripe: they will not inflate a weak lift — which was exactly what we needed before scaling the placement.”Owen R., CRM manager, multi-brand catalogue
“Quarterly readouts keep our fashion accessories recommendations honest. When attach dipped after a navigation change, the chart pack showed it before the next catalogue print.”Hannah L., catalogue planning
Extended story: Spring window, kitchenware pairs
A mid-size GB kitchenware retailer commissioned a cross-sell recommendation lift study ahead of a spring catalogue drop. The question: did “frequently bought with” tiles on cookware PDPs raise utensil attach without cannibalising higher-margin sets?
Constraints: two brands shared a storefront but used different category trees; one week of the window overlapped a free-shipping promotion. WillowCore Desktop split the analysis by brand, excluded free-shipping days from the primary lift cut, and noted the promotion as a sensitivity check.
Outcome: Brand A showed a clear attach-rate lift on utensils under £25; Brand B was flat. The briefing recommended keeping the tiles on Brand A and pausing Brand B until pair quality improved — a catalogue review followed for Brand B’s recommendation list.
Extended story: Membership upgrade attach
A membership organisation asked for a visualisation briefing after an in-house test of upgrade prompts at checkout. Numbers existed in a spreadsheet; the board pack did not. Six plates reframed the lift by tenure band and channel. The board approved a limited rollout to web checkout only, deferring app prompts until a cleaner control was available.
