Use Baskets to Decide What to Promote, Not Guess
Analyse product affinities to grow AOV and margin with smarter cross-sell and bundles.
The Problem
Most product and promotion decisions still rely on intuition:
Cross-sell rules are generic (“related products”) and not grounded in purchase patterns.
Promotions are set at category level, with little view of attach rates or halo effects.
Planograms and recommendation slots ignore real co-purchase behaviour.
Finance cannot clearly see which bundles build margin vs. destroy it.
Result: wasted promotion spend, flat basket size, and limited improvement in contribution per order.
Business Outcomes
Increase basket size and AOV by promoting products that are actually bought together.
Improve margin by designing bundles and promos that lift profitable combinations, not just volume.
Strengthen category roles by clarifying traffic drivers, margin builders, and attachment SKUs.
Inform pricing and layout with data on substitutes vs. complements at SKU level.
