Three Scenarios, One Right Answer
Without knowing your exact Lift & Confidence, any discount is a guess. See how the data shifts the outcome:
Hidden Synergy
Products with strong synergy (Lift 3.0×) but low organic overlap — customers want both but rarely discover the pairing on their own.
Projected Uplift
+$733/mo
Optimal discount: 8% Off
The Margin Trap
Products that seem popular together (Conf. 25%) but have only average synergy (Lift 1.6×). The discount eats more margin than it creates.
Fragile Profit
L:1.6× / C:25%
+$0/mo
⚠️ If Lift drops to 1.3, profit turns negative. Do you know your exact number?
Substitutes
Products that compete with each other (e.g. Vanilla vs Chocolate). Bundling forces a hard choice.
Outcome
Conversion drops because customers feel forced into a compromise.
✕ Do not bundle these products.
Mastering the Mechanics
Profitability comes down to understanding two hidden numbers in your data: Lift and Confidence.
Lift (The "Synergy" Score)
Measures how much more likely two products are bought together compared to random chance.
- > 1.0: Positive synergy (They sell each other)
- < 1.0: Competition (They kill each other)
Confidence (The "Habit" Score)
The percentage of buyers who purchased Product A that also purchased Product B.
- High (>30%): Strong organic habit. Don't discount.
- Low (<10%): Weak connection. Needs a nudge.
The 3 Golden Rules
Hidden Synergy
Customers love these together but rarely find them. This is your "Gold Mine."
Organic Habit
They are already buying both. A discount here is just a donation to the customer.
False Friends
These products compete (e.g. Vanilla vs Chocolate).
Forcing a choice kills conversion.
