A struggling affiliate program usually isn’t unlucky. It’s making the same avoidable mistakes that look fine on a GMV chart while margin quietly leaks out the back. Here are the five to kill first.

1. Flat commissions across every product. Paying the same rate on a 70%-margin hero and a 15%-margin filler means you either underpay your winners or overpay on products that can’t carry it. Tier by margin.
2. Picking creators by follower count. Reach without engagement is vanity. A smaller, engaged, on-niche creator converts better and costs less.
3. Sending samples into a black hole. Free product with no tracking and no follow-up is just shrinkage. Log every sample and tie it to output.
4. Ignoring inventory and fulfillment. A video going viral while you’re out of stock or shipping slowly burns the exact momentum you paid to create.
5. Chasing GMV while contribution margin falls. “Sales are up” means nothing if commissions, discounts, and returns mean you lose money on each order. Track the number that actually matters.

Fix these and the same program that was leaking starts compounding. Want a margin-safe affiliate engine built properly? That’s what we do. Let’s talk.
