Affiliate Tiers on Lite by Stacking Programs

How to pay some affiliates a higher rate than others on Siren Lite without ever paying two commissions on one order: a base program every affiliate is in, plus a top-up program only the higher tier is in.

You want some affiliates to earn 10% and the rest to earn 5%. The obvious build is two programs, one at 5% and one at 10%, with each affiliate in one of them. On Siren Lite that build can pay both affiliates on the same order. This page explains why, and shows the build that cannot.

Every program attributes on its own

Each program decides credit by itself. When an order completes, Siren evaluates every program that could match it, and each matching program pays its own winner. Programs stack. A customer who clicked a regular affiliate’s link on Monday and a top affiliate’s link on Thursday has engaged with both, so a 5% program and a separate 10% program both fire, and that one order pays 15% across two people.

On Essentials and above, a program group fixes this by letting only one program in the group fire per conversion. On Lite there are no program groups, so the fix is in how you build the programs.

The build that never double pays

Make the tiers add up instead of competing.

  1. Create a base program at the lowest rate, 5% in this example, and enroll every affiliate in it, the top tier included.
  2. Create a top-up program at the difference, another 5% here, and enroll only the affiliates who should earn 10%.

Now walk the same order through it. The base program has every affiliate in it, so whichever engagement wins under its attribution rule, first touch or last touch, it pays 5% once. The top-up program only has the higher tier in it, so it fires only when one of them was part of the journey, and pays 5% more to that person. A top-tier affiliate who brought the sale earns 10%. A regular affiliate earns 5%. And the order never pays more than 10% in total, whoever clicked what, because the base program picks one winner and the top-up cannot fire for anyone outside it.

The rates in the top-up are the difference, not the tier’s full rate. For three tiers at 5%, 10%, and 15%, that is a base program at 5% with everyone in it, a second 5% program with the middle and top tiers in it, and a third 5% program with the top tier alone.

When to use a program group instead

On Essentials, Plus, or Pro, a program group with one program per rate is simpler to read in the dashboard and gives you the group’s own tie-break rules. The stacked build above still works on every plan, and it is the only safe build on Lite.
