There are different billing methods in performance marketing. Here are some examples: Cost per Click (CPC): The advertiser only pays when someone clicks on the ad. Cost per Action (CPA): The advertiser only pays when a specific action is performed, such as a sale or registration. Cost per Lead (CPL): The advertiser only pays when a prospect leaves their contact details (e.g. email address). Cost per View (CPV): The advertiser only pays if the video has been viewed in full. The choice of billing method depends on the type of product or service being advertised, as well as the advertiser's goals and strategy.
