Promo-Code Attribution: The Fastest Way to Pilot Influencer Marketing

Brands often delay creator marketing because they think it requires infrastructure: an app, a pixel, an integration project someone has to own. The fastest path needs none of that. It needs a discount code.

Why codes are underrated

A per-creator promo code does three jobs simultaneously:

• Attribution: the code lands on the order, tying the sale to one creator with zero ambiguity. It works on literally any cart that supports discounts, which is all of them.
• The offer: the discount gives the creator's audience a reason to act now, and gives the creator something concrete to present.
• Measurement of the discount itself: because the code is the tracking, every dollar of discount is tied to a measured sale. No more "did that 15%-off promo do anything?"

Running a two-week pilot

1. Pick one product line with healthy margin: commission plus discount should leave you clearly positive on contribution.
2. Set one commission rate. Around 15% of net revenue is a common starting point; high-margin products can go higher to attract stronger creators.
3. Issue one code per creator. Never share codes between creators, the whole point is that one code means one creator.
4. Count only net revenue. Decide up front that refunded orders reverse their commission, and hold payouts through your return window.
5. Judge on orders, not impressions. The pilot question is "which creators produce buyers," not "which posts got reach."

What codes can't do, and what comes next

Codes miss the buyer who watched the video but checked out without typing anything. That's real, and it means code-only numbers understate creator impact, a conservative bias, which is the right direction for a pilot. When you're ready to capture the rest, add tracked links that carry attribution through checkout at the cart level, and landing pages that capture the visitors who don't buy today as leads.

Start with the code. Scale with the funnel.
