Conversion

A conversion is whatever the program says it is, which is why the word means different things in different programs. Retail programs almost always mean a completed purchase. Lead-generation programs mean a submitted form that passes a quality check. Subscription programs frequently mean a paid signup that survives a minimum period, so a trial that cancels in week one never becomes a conversion at all.

Technically it is a single event fired at the moment of the action, carrying an order identifier, a value, and whatever referral evidence exists — a click identifier from a first-party cookie, a promo code, or both. The order identifier is what makes the event idempotent: fire it twice and a correctly built program records one conversion, not two.

The definition decides how much of your traffic can possibly pay. Sending highly qualified readers to a program that only counts an annual plan, when your audience buys monthly, produces clicks that convert in the ordinary sense and never convert in the program's sense.

It is worth reading the definition before the rate. A 30 percent commission on a conversion defined as a paid plan retained past day 30 can pay less in practice than a 15 percent commission on any completed checkout.

Defining the conversion is where a brand controls quality. Paying on a trial signup buys volume and invites low-intent traffic; paying on a retained subscription buys quality and slows partner cash flow, which shrinks the pool of partners willing to work the program.

Whatever the definition, the event has to fire reliably from a place the partner cannot influence — server side, on the confirmed order — and it has to be deduplicated. Client-side conversion pixels are blocked often enough that a program relying on them alone systematically underpays and quietly loses its partners.
