Cross-sell recommendation lift study
A fixed-scope comparison of control and exposed baskets that quantifies attach-rate lift for named recommendation placements.
Who it is for
Retail and catalogue teams that place cross-sell recommendations on product detail pages, baskets, or post-purchase journeys and need a clear answer: did the placement raise attach rates, by how much, and under which constraints?
Result you receive
A written lift summary for one agreed trading window, a pack of annotated visualisations (attach rate, contribution by category, and placement comparison), and a 60-minute briefing for buyers or CRM stakeholders. The pack is designed to travel into a merch meeting without a second interpretation layer.
Scope included
- Agreement on recommendation surfaces, control logic, and exclusion rules
- Data quality checks on order lines, recommendation impressions, and category tags
- Lift calculation for the primary attach-rate metric you nominate
- Up to eight chart plates with callouts in trading language
- One revision cycle on the written summary
- One live briefing (video or Bristol office)
Out of scope
Building or hosting a recommendation engine, continuous model monitoring, or redesign of the storefront. We analyse lift on placements you already run.
Provider and process
Analysts at WillowCore Desktop Ltd lead the study from our Bristol office. Typical stages: discovery call → data access checklist → interim readout → final pack → briefing.
Preparation
You provide order and recommendation logs for the window (or a secure extract), a dictionary of placement IDs, and a named contact who can confirm category mappings within two working days of questions.
Constraints
Minimum window length is usually two full trading weeks. Multi-brand groups may need separate slices if assortments do not share category trees.
Next step
Request a lift briefing with your catalogue context and preferred window. We reply within one working day with fit notes and a draft fee band.
