A flat commission rate across every partner type is the most expensive structure a program can run. It pays the same for revenue you were always going to earn as it does for revenue a partner genuinely created — and because last-click attribution favours whoever sits closest to the checkout, the flat rate quietly redirects budget away from the partners building demand.
A flat rate across every partner type is the easiest structure to launch and the most expensive one to keep.
Where does the leakage start?
Last-click attribution rewards whoever sits closest to the checkout. Left unmanaged, budget drifts toward coupon and loyalty placements that intercept existing demand, while the editorial and creator partners who actually create it get paid the same or less.
The leak is invisible in a revenue chart, because the revenue is real. What changes is its cost. A customer who searched your brand name, hit a coupon extension on the checkout page and completed a purchase they had already decided on has just cost you a commission you did not need to pay.
Which structures erode margin fastest?
Four patterns account for most of it:
- One flat rate for every partner. The default setting on most platforms, and the one that treats a first-touch review and a checkout coupon as equal contributions.
- Unmanaged coupon and loyalty placements. Valuable in moderation, corrosive when they are allowed to claim brand-name and retargeting traffic.
- Commission on discounted and clearance product. Paying a full rate on already-thin margin, often on the exact SKUs you were trying to move quickly.
- Rates that never get revisited. A structure set at launch and left for three years is priced for a business that no longer exists.
What should you do instead?
Segment commission by partner type and by role in the funnel. Pay a premium for first-touch content that introduces the brand, and hold closing placements to a rate that reflects what they contribute rather than where they sit.
The practical version of that is a tiered structure:
- Editorial and creator content: premium rate, because it creates demand that did not exist.
- Comparison, review and deal content in-category: standard rate, because it shapes a decision already underway.
- Coupon, loyalty and cashback: reduced rate, with brand-name and post-checkout activity excluded.
- Discounted and clearance product: reduced rate or excluded entirely.
Then police it. A tier structure with no rules about brand bidding, coupon sourcing or attribution windows will drift back to a flat rate within two quarters.
Does restructuring cost you partners?
It costs you some, and the ones it costs are usually the ones you were overpaying. The relationships worth keeping are with partners producing content that survives past the click — and they respond well to being paid more than the placement that intercepted their reader at checkout.
When Worldwide Golf shifted its mix toward editorial and creator partnerships, those relationships came to drive 48% of all affiliate revenue, traffic grew 35% year over year, and conversion nearly doubled from 0.68% to 1.24%. At Jenson USA, rebuilding the commission structure around partner type and product margin moved return on ad spend from 8× to 13×.
How do you know if yours is leaking?
Three checks, none of which need a new tool:
- What share of affiliate revenue comes from partners whose content a customer could have read before deciding to buy?
- What share of conversions involve a brand-name search in the path?
- When did you last change a commission rate for a reason other than a partner asking?
