Coupon leakage

Coupon leakage (discount code leakage)

Affiliates

Coupon leakage is when a discount code meant for one audience spreads to coupon sites, extensions or other shoppers, giving away discounts you didn’t intend.

What is Coupon leakage?

A code made for one creator’s followers or one email list often ends up on coupon sites within days. Shoppers who were going to buy anyway find it at checkout, and the brand loses margin on orders it would have won at full price. The commission side: if your program credits sales by code alone, leaked codes also pay partners for those orders. Ways to limit it: single-use or per-customer codes, usage caps and end dates, smaller discounts on public codes, and crediting partners by tracked link click rather than by code alone.

Example

A brand gives one creator a 25% code. A month later, most of the code’s uses come from shoppers who arrived from coupon sites, not from the creator.

Why Coupon leakage Matters

Leakage quietly lowers margin on full-price orders and can make a partner look like a top seller when they aren’t.

How do I stop coupon leakage?
