Cost Per Action (CPA): In the context of online advertising and marketing, CPA refers to a pricing model where advertisers pay a fee based on a specific action taken by the audience. This action could be a click, form submission, sale, or another predefined conversion event. Advertisers pay only when the desired action occurs, making it a performance-based advertising model.
