Which promotions actually make money
The situation
- Promotions ran every week, and sales moved, but nobody could say which events earned their discount
- Reviews compared sales during the promo to sales before it, ignoring cannibalization and stock-up buying
What the diagnostic does
- Measures true uplift per event, after cannibalization and forward-buying
- Scores every promo on ROI and flags the ones that only give margin away
- Rebuilds the calendar around the events that work
