CPA (cost per action) marketing is a performance model where an advertiser pays a publisher only when a user completes a specific action, such as a sign-up, a form submission, a free trial, an app event or a purchase. For advertisers it means paying for results; for publishers it means earning per completed action instead of per click.

Key takeaways

The "action" is defined by the advertiser and written in the offer terms.
CPA covers many actions: leads, trials, deposits, installs with events, sales.
Traffic quality matters; invalid actions are rejected.
Start with one offer, one traffic source and careful tracking.

How CPA marketing works

The advertiser lists a CPA offer with payout, target countries and allowed traffic.
A publisher gets a tracking link from a network or program.
The publisher sends traffic using content, email, ads or social.
The user completes the action.
The conversion is tracked (ideally via postback), validated and paid.

Common CPA offer types

Offer	Action
Lead generation	Form submission (CPL is a type of CPA)
Free trial	Trial sign-up
Finance	Account opening, card application, deposit
App	Install plus registration or first purchase
E-commerce	First order

Traffic sources for CPA

SEO content and comparison pages
Email newsletters
Paid search, social and native ads (follow offer rules)
Push and display where allowed
Communities and creators

Always check which traffic sources each offer allows.
