Affiliate marketing is the performance marketing motion where a partner promotes a vendor's product to their own audience through tracked links or codes, the tracking system attributes the resulting clicks, leads, or sales automatically, and the vendor pays the partner per tracked outcome. The motion has a partner type attached to it: the affiliate is the partner running the motion, affiliate marketing is the motion itself. The vendor owns the customer, the contract, and the invoice from the first touch; the affiliate usually never knows who the individual buyer is.
How the Motion Works
Three mechanics define the motion. First, tracked promotion: the affiliate embeds a unique link or discount code in their content (a review site, newsletter, video, or course), and every visitor who follows it carries the affiliate's identifier. Second, automatic attribution: an attribution window (commonly 30 to 90 days) decides how long after the click a conversion still counts for the affiliate. No human registers anything; the tracking system decides who gets paid. Third, performance payouts, in one of three models: CPC (paid per click), CPL (paid per qualified lead), or CPS (paid per sale, typically a percentage of the transaction). CPS dominates because it ties payout to revenue rather than traffic.
Affiliate Marketing vs Referral
The difference is not who invoices the customer. Neither affiliates nor referral partners ever invoice; the vendor holds the customer relationship in both motions. The real axis is how the prospect is handed off and how the partner is paid. An affiliate broadcasts to an audience, attribution happens automatically through the link, compensation is per click, lead, or sale at volume, and the affiliate rarely knows any individual buyer. A referral partner introduces specific prospects they personally know, the referral is usually registered manually, and they are paid on closed business. Affiliate marketing scales on traffic; referral runs on low volume and high trust.
Where It Fits in a Partner Program
Affiliate marketing sits in the Marketing category of a partner program, alongside other marketing partners. Its job is awareness and customer acquisition at scale: thousands of small, tracked transactions rather than a handful of relationship-driven deals. Because payouts are formulaic (see commission-based pricing), the program lives or dies on tracking integrity, attribution rules affiliates trust, and reliable payment, not on joint selling.
