commission mechanics
Cost Per Lead (CPL)
A commission paid when a referred visitor submits their details — no purchase required.
What is Cost Per Lead (CPL)?
Cost per lead (CPL) is a commission structure in which an affiliate earns a fixed payment when a referred visitor completes a defined information-submission action — typically a name and email form, free trial signup, or quote request — without requiring that visitor to make a purchase.
Cost Per Lead (CPL) In Practice
CPL is a type of CPA (cost per action) where the qualifying action is lead submission rather than purchase. The advantages: higher conversion rates than purchase-based CPA (because asking for contact details has a lower commitment threshold than asking for a credit card), and payment is immediate rather than contingent on a downstream sale. The disadvantages: lower per-event payment rates than purchase-based CPA (because the merchant still needs to convert the lead internally), and higher reversal risk on poorly qualified leads. CPL rates vary significantly by vertical: insurance leads pay $15–$40 per qualified lead, financial services $20–$100, B2B software trials $20–$50 per verified registration. The qualification criteria determine what percentage of submitted forms actually trigger payment — a program paying $35 per lead but rejecting 40% of submissions has an effective rate of $21 per referred visitor who completes the form.
Example of Cost Per Lead (CPL)
An affiliate promotes a life insurance comparison program through a personal finance content site. The program pays $28 per qualified lead — defined as a completed quote request with a valid phone number and age within the program's eligible range. The affiliate drives 500 visitors to the quote form in a month. Of those, 62 complete the form (12.4% conversion — higher than a purchase CPA). Of those 62, 11 are rejected because they fall outside the age eligibility criteria. The 51 qualified leads earn $1,428. Without knowing the rejection criteria upfront, the affiliate projected 62 commissions at $1,736 — a $308 gap created by unqualified submissions.
