What metrics should I monitor to measure discount campaign success?

Question

As an e-commerce business owner, I'm struggling to understand which metrics truly matter when evaluating the performance of my discount campaigns. I want to move beyond simple revenue numbers and gain deeper insights into how discounts impact my overall business strategy. I need a comprehensive approach to tracking campaign effectiveness that goes beyond surface-level metrics and helps me make data-driven decisions about future promotional efforts.

Key Metrics to Monitor for Discount Campaign Success
A discount campaign that drives sales but destroys margins is not a success. Measuring the right metrics - not just top-line redemptions - separates profitable promotions from expensive mistakes.

Core Performance Metrics

MetricWhat It Tells YouHealthy Signal

Redemption Rate% of exposed visitors who used the code5-15% for targeted campaigns
Revenue Per RedeemerAOV of orders using the discountShould exceed non-discount AOV after offer cost
Margin Per OrderGross profit after discount appliedMust remain positive - never sell below cost
New vs. Returning SplitWho is redeeming - new or existing customers?Acquisition campaigns: 70%+ new customers
Incremental RevenueSales above your no-discount baselinePositive - discount caused additional purchases
Offer Leakage RateRedemptions from unintended audiencesUnder 10% for targeted campaigns

The Cannibalization Problem
The most dangerous blind spot in discount analytics is giving credit for sales that would have happened anyway. If 40% of your discount redeemers were dedicated buyers who planned to purchase at full price, you paid for nothing. Always compare redeemer behavior against a control group or your baseline conversion rate to calculate true incrementality.

LTV Impact (30-90 Day View)
A discount might be profitable in isolation but damaging long-term if it trains customers to only buy on sale. Track repeat purchase rate and average time-to-second-purchase for discount vs. full-price first-time buyers. If discount-acquired customers repurchase at lower rates, adjust your targeting strategy accordingly.

Growth Suite Analytics
Growth Suite's Funnel Report and Cart Insights break down exactly which visitor segments redeemed offers, what they ordered, and how that compares to non-offer behavior - giving you the incremental view automatically rather than requiring manual baseline comparisons.
