CPA marketing stands for cost per action or cost per acquisition marketing. It is a type of affiliate marketing where businesses partner with publishers, influencers, or bloggers to promote their products or services to their audience. The affiliate earns a commission when a reader takes a specific action, such as filling out a form, clicking through to a specific webpage, or making a purchase. CPA marketing is considered cost-effective because businesses only pay when someone interacts with their ad or link. CPA marketing can be used to promote a brand, a new product, an event, or a discounted service. CPA marketing is different from other forms of performance-based advertising, such as CPC (cost per click) and CPM (cost per mille) pricing models. CPA marketing is a low-risk strategy for businesses because they only pay for the ads that lead to a specific action.
