Siren Affiliate Manager is an exceptionally well-designed and thoughtfully built WordPress plugin. If you're running an affiliate program with multiple affiliates, different transaction types, or custom engagement triggers that need to generate commissions, this tool gives you serious power and flexibility. What really sets it apart, though, is the developer. Alex has been incredibly helpful and willing to customize the plugin for my specific use case. More importantly, he was focused on creating real value for my business - not just billing hours. That kind of mindset is rare. The plugin is robust, flexible, and clearly built by someone who understands real-world affiliate program complexity. I can't recommend Siren highly enough.

What This Recipe Does

This recipe creates a single lead generation program with last-touch attribution. Affiliates earn a flat $15 bounty for every qualifying form submission they refer. When multiple affiliates interact with the same prospect, the affiliate whose engagement was most recent before the conversion earns the bounty.

This structure is built for campaigns with short conversion windows where the final affiliate interaction is the strongest signal of who drove the lead.

Who It’s For

Campaign managers running time-boxed lead generation pushes where speed to conversion is the priority
Businesses with short sales cycles where leads convert within days, not weeks
Teams that prefer last-touch attribution because the affiliate closest to the conversion moment deserves credit

How It Works

When you apply this recipe, Siren creates a program that listens for collaborator form submissions. This event fires when a visitor referred by an affiliate submits a tracked form through a compatible plugin like Gravity Forms.

Attribution uses last-touch logic. If multiple affiliates interacted with the same prospect over time, the affiliate whose engagement was most recent before the form submission gets credit. This “newest binding wins” approach rewards the affiliate who was actively driving the prospect at the conversion moment, not necessarily the one who found them first.

This makes the program well-suited for short campaigns, seasonal promotions, and situations where your affiliates are actively competing to convert the same audience during a compressed timeframe. The affiliate doing the work right before the lead submits the form is the one who gets paid.

Each qualifying form submission triggers a flat $15 commission. The payout is fixed and does not depend on any transaction amount, giving you a predictable cost per lead.

How the Cost-Per-Lead Campaign Works in Siren

1

Start with a ready-made program

This recipe treats a form submission, not a sale, as the conversion. It creates a program that pays affiliates a flat $15 bounty per qualifying lead, with last-touch attribution already set.
2

Define partners and eligibility

Add the affiliates competing for your campaign as collaborators. Because credit follows the most recent touch, every partner has a reason to stay active right up to the conversion.
3

Set tracking rules

Gravity Forms is the tracking engine. Siren listens for the collaboratorFormSubmitted event on the forms you choose, and no purchase needs to happen for an affiliate to earn the bounty.
4

Customize rewards

The $15 per lead is a default, not a rule. Set the bounty to whatever your campaign economics support when you apply the recipe, then change it later without rebuilding the program.
5

Manage approvals and payouts

Review each lead before its bounty pays out, approving the real ones and rejecting the junk. Since every payout is the same flat amount, budgeting the campaign is simple multiplication.

Why Use Siren for a Cost-Per-Lead Campaign?

Traditional lead tracking software tools	Siren
Built for one program type	Built for multiple incentive programs
Often limited to one reward model	Supports commissions, bounties, royalties, revenue share, and bonuses
Rewards usually tied to one action	Rewards can be tied to different measurable actions
Harder to manage overlapping programs	Program groups and rules control how programs interact
May require multiple tools as you grow	Supports different partner programs from one system

Dedicated lead tracking software counts leads but rarely pays the people who produced them. With Siren the payout is the point, and when the campaign wraps, the same install can move on to the sales, referral, or tiered programs that usually follow a lead push.

Similar Programs, and When to Use Each

Recipes that share machinery with this one, the rule that actually separates them, and the situation where the other recipe is the better pick.

Program	How it differs	Use it instead when
Pay-Per-Lead Affiliate Program	The Pay-Per-Lead Affiliate Program runs on first-touch attribution, meaning whoever brought a prospect in first keeps the credit no matter who engages that person later, whereas the Cost-Per-Lead Campaign awards the newest touch. The Pay-Per-Lead default bounty is also higher: $25 per lead against the Cost-Per-Lead Campaign's $15.	Pick the Pay-Per-Lead Affiliate Program when deals close weeks after the form fill and you want the introducer to hold credit through the whole cycle.

Siren works as the incentive layer behind the systems where partner-driven actions happen: your website, checkout, ecommerce store, forms, LMS platform, subscription flow, or custom workflow.

Frequently Asked Questions

What is a cost per lead campaign?

A cost per lead campaign pays partners a fixed amount for every qualified lead they generate, usually a form submission, rather than a cut of an eventual sale. You know your acquisition cost before the campaign starts because every lead costs the same flat fee. That predictability makes it a common structure for agencies and short promotional pushes.

How does a cost per lead campaign work?

An affiliate sends a prospect to your site, the prospect submits a tracked form, and the affiliate earns a flat bounty for that lead. In this recipe the tracked event comes from Gravity Forms, and last-touch attribution decides who gets paid when several affiliates touched the same prospect. The bounty defaults to $15, and you can change it when you apply the recipe.

How is this different from the Pay-Per-Lead recipe?

Attribution. The Pay-Per-Lead recipe uses first-touch attribution, crediting the affiliate who originally introduced the lead. This recipe uses last-touch attribution, crediting the affiliate whose interaction was most recent before the form submission.

When should I use last-touch instead of first-touch attribution?

Last-touch works best for short sales cycles, time-sensitive campaigns, and situations where the final push matters more than initial discovery. If your leads typically convert within a few days, last-touch rewards the affiliate who was actively driving engagement at the moment of conversion.

Can I run this alongside a sales-based affiliate program?

Yes. This program tracks form submissions independently. If a lead later makes a purchase tracked by a separate sales-based program, both programs fire on their respective events without conflict.

What form plugins are supported?

Siren integrates with Gravity Forms for the collaboratorFormSubmitted engagement event. You configure which forms are tracked in your Siren settings.
