What Is CPA?

Cost Per Action explained for affiliates & publishers

What Does CPA Mean?

CPA stands for Cost Per Action. In CPA advertising, advertisers pay publishers or affiliates only when a specific action is completed by a user.

Unlike CPM or CPC models, CPA focuses on real results such as signups, app installs, form submissions, or purchases.

How CPA Advertising Works

CPA advertising involves three main parties: the advertiser, the CPA network, and the publisher (affiliate).

  • The advertiser creates an offer
  • The CPA network tracks conversions
  • The publisher sends traffic to the offer
  • Payment is made only after an action is completed
Example:
If a CPA offer pays $5 per signup and you generate 20 signups:
Earnings = 20 × $5 = $100

Common Types of CPA Actions

  • Email or account signups
  • App installs
  • Lead form submissions
  • Free trials
  • Product purchases

Why CPA Is Popular

CPA is popular because advertisers only pay for real results, while publishers can earn significantly higher payouts per conversion.

  • High payouts per action
  • Performance-based earnings
  • Scalable with targeted traffic

Advantages of CPA Advertising

  • No earnings limit per conversion
  • Best for targeted and intent-based traffic
  • Higher ROI for advertisers
  • Works well with paid traffic sources

Disadvantages of CPA

  • Requires high-quality traffic
  • Lower conversion rates compared to CPM
  • Offer compliance and rules must be followed

CPA vs CPM vs CPC

  • CPA: Paid per completed action
  • CPC: Paid per click
  • CPM: Paid per 1,000 impressions

CPA is best for affiliates who understand traffic targeting, while CPM works better for large-volume publishers.
