What are some common CPA pricing models?

CPA (Cost Per Action) pricing models are used to determine how advertisers pay for desired actions or conversions generated by affiliates. These models specify the type of action advertisers are willing to pay for and the corresponding payment structure. Here are some common CPA pricing models:

1. **Cost Per Sale (CPS)**: In the Cost Per Sale model, advertisers pay affiliates a commission for each sale generated through their referral. The commission is typically calculated as a percentage of the sale amount or a fixed dollar amount per sale.

2. **Cost Per Lead (CPL)**: In the Cost Per Lead model, advertisers pay affiliates for each qualified lead they generate. A qualified lead is typically defined as a potential customer who has expressed interest in the advertiser's product or service by completing a specific action, such as filling out a form, signing up for a trial, or requesting more information.

3. **Cost Per Click (CPC)**: While CPC is more commonly associated with pay-per-click advertising, it can also be used as a CPA pricing model. Advertisers pay affiliates for each click generated through their referral, regardless of whether the click results in a conversion.

4. **Cost Per Install (CPI)**: In the Cost Per Install model, advertisers pay affiliates for each app install generated through their referral. This model is commonly used in mobile app marketing, where advertisers seek to acquire new users for their mobile applications.

5. **Cost Per Action (CPA)**: The Cost Per Action model is a general term that encompasses various types of actions for which advertisers are willing to pay. This could include sales, leads, clicks, installs, or other desired actions specified by the advertiser.

6. **Cost Per Acquisition (CPA)**: CPA is often used interchangeably with Cost Per Action, but it specifically refers to the cost advertisers incur to acquire a new customer or user. Advertisers pay affiliates a commission for each new customer or user they acquire through their referral.

7. **Cost Per Conversion (CPCv)**: In the Cost Per Conversion model, advertisers pay affiliates for each desired conversion, which could include sales, leads, sign-ups, registrations, or other specified actions.

8. **Cost Per Engagement (CPE)**: In the Cost Per Engagement model, advertisers pay affiliates for each user engagement or interaction generated through their referral. This could include actions such as likes, shares, comments, downloads, or other forms of user engagement.

These are some of the common CPA pricing models used in affiliate marketing and online advertising. The choice of pricing model depends on the advertiser's objectives, the type of action they want to incentivize, and the industry or vertical in which they operate.
