There are three common types of CPA offers: cost per sale (CPS), cost per lead (CPL), and cost per install (CPI).
CPS, as its name suggests, refers to offers where visitors make a purchase, which will entitle the affiliate to a commission. Advertisers only pay affiliates for every purchase made using the affiliate’s referral link.
CPL offers pay affiliates for every qualified lead that converts, such as when a visitor signs up for a paid subscription or submits their email for a mailing list.
Cost per install offers refer to conversions where a visitor downloads an app or an extension and installs it.
