Definition
Cost per acquisition — a one-off payment per referred player who registers and deposits.
Under a CPA deal the affiliate is paid a fixed amount for each qualifying player and nothing afterwards, regardless of how much that player goes on to spend. The operator takes the long-term risk and the upside; the affiliate takes a known sum now.
How it works
Qualification is where the detail sits. A CPA rarely triggers on registration alone — the usual condition is a first deposit above a minimum, sometimes a volume of play, often completion of identity checks, and almost always survival of a short fraud window.
Rates vary by market, product and player value, and are commonly tiered by volume. Both sides are pricing the same unknown from opposite directions: the operator estimates what a player is worth over their lifetime, the affiliate estimates how many will qualify.
Negative carryover does not apply here, which is CPA’s main attraction. Once a player qualifies, the payment is made and is not set against their later wins.
Why it matters in iGaming
CPA makes revenue predictable, which matters in a sector where a market can close or an operator can exit without notice. It also pays quickly, which funds the content and link work that has to happen before any of it earns.
The trade is the ceiling. A player who stays for years is worth a multiple of the one-off fee, and that difference belongs entirely to the operator — so CPA suits sites with high volume and short-lived traffic, while a site with a durable audience is usually leaving money behind.
Example
An affiliate is offered a fixed sum per qualifying player, or a share of net revenue. For a market where players churn within weeks, the fixed sum is worth more than the share will ever be. For a market with long retention, the same choice costs the affiliate several times the fee over two years.
Common mistakes
- Reading the rate without the conditions. A high headline figure attached to a strict qualification threshold can pay less in practice than a lower one that triggers easily.
- Ignoring the fraud window. Payments reversed weeks later are a real cost, and a programme’s reversal rate is worth asking about before signing.
- Taking CPA everywhere by default. The choice should follow retention in the specific market, and retention differs enough between markets to flip the answer.
