CPA: Cost Per Action/Acquisition – CPA is a pricing model where advertisers pay for a specific action or conversion that a user takes. This action could be making a purchase, filling out a form, subscribing to a service, or any other predetermined action. Advertisers are charged only when the desired action is completed.
CPL: Cost Per Lead – CPL is a pricing model where advertisers pay for each lead generated. A lead refers to a potential customer who has expressed interest in a product or service by providing their contact information, such as email address or phone number. Advertisers are charged for each qualified lead they receive.
CPS: Cost Per Sale – CPS is a pricing model where advertisers pay a commission for each sale generated through their marketing efforts. Advertisers typically establish an affiliate program and pay a predetermined percentage or fixed amount for every successful sale referred by the affiliates.
SOI: Single Opt-In – SOI refers to an opt-in process where users provide their information with a single action, such as submitting a form or email address. In the context of lead generation, SOI typically indicates that a user has shown initial interest by providing their details but hasn’t completed any further actions to confirm their interest.
DOI: Double Opt-In – DOI refers to an opt-in process that requires users to take two actions to confirm their interest. After initially providing their information, such as email address, users receive a confirmation email containing a link or verification code. They need to click the link or enter the code to complete the opt-in process. DOI is considered a more secure method for ensuring user consent and reducing the likelihood of fake or incorrect email addresses.
These terms are often used in online advertising and affiliate marketing to define the pricing models and actions associated with different marketing campaigns.
