Split Commission Program

What This Recipe Does

This recipe creates a single affiliate program with performance-weighted commission splitting. When multiple affiliates contribute to a sale, the total 20% commission is divided proportionally based on each affiliate’s engagement score. Collaborators who drove more engagement earn a bigger piece of the payout.

This is different from equal-split attribution. In an equal split, three affiliates each get one-third regardless of contribution. In a performance-weighted split, the affiliate who drove five site visits earns a larger share than the one who contributed a single coupon code. The math rewards effort.

Who It’s For

• Partnership marketers running coordinated campaigns where bloggers drive awareness and deal sites close sales
• Affiliate managers who find equal splits unfair but still want every contributor rewarded
• Multi-channel brands where affiliates interact with customers across referral links, coupon codes, and other touchpoints

How It Works

When you apply this recipe, Siren creates a program that tracks two engagement types: referred site visits and bound coupon usage. Each event type carries a point value (100 points by default). As customers move through your store, Siren records every affiliate interaction along the way.

When a customer completes a purchase, Siren calculates each contributing affiliate’s total engagement score and divides the 20% commission proportionally. If Affiliate A accumulated 300 points (three site visits) and Affiliate B accumulated 100 points (one coupon use), Affiliate A receives 75% of the commission and Affiliate B receives 25%.

This proportional approach solves a common frustration with multi-touch programs. Equal splits can feel unfair when one affiliate did most of the work. Winner-take-all models discourage collaboration entirely. Performance-weighted splitting finds the middle ground: everyone who contributed gets paid, and the payout reflects how much they contributed.

You can fine-tune the weighting after installation by adjusting the point values on each engagement type. Setting coupon usage higher than site visits, for example, would reward affiliates who close over those who only drive traffic.

Commissions are calculated on line items only, so shipping, taxes, and fees are excluded.
