Compare a coupon ad with a full-price ad
Evaluate the effect of a discount on acquisition and contribution.
Use settled order economics
A full-price ad generates 40 orders with $35 contribution each before media. A coupon ad produces 60 orders with $23 each. At the same spend, pre-ad contribution is $1,400 versus $1,380.
Check what the coupon displaced
Some buyers would have purchased at full price. A comparable holdout helps estimate that effect. Review new and repeat buyers separately, and check whether the discount pulled orders forward from the following week.
Include guardrails in the test
Track returns, capacity, and the number of shoppers who cannot redeem the advertised offer. Keep coupon eligibility visible before checkout.
