Mobile App Promotion Strategies​: CPI vs. CPA vs. CPC Advertising Models

Choosing the right mobile app promotion strategies helps you save your budget and increase real installs. Therefore, it is important to understand the key differences between CPI vs. CPA vs. CPC advertising models. Let us begin by understanding what each advertising model means.

To start with, Cost Per Install CPI  or CPI simply means you pay only when someone installs your app on their phone. For example, if 100 people click your ads but only 10 installs, you pay for those 10.

On the other hand, Cost Per Action or CPA is used when you want users to do more, such as sign up or buy something. In the end, CPC or Cost Per Click charges you when someone clicks your ads, even if they do not install. So this is the main difference among mobile advertising models.

What Are Some Major Pros and Cons of CPI vs. CPA vs. CPC Adv. Models?

Every strategy works well, but only if used the right way. For example, CPI is good for boosting downloads fast at a low cost. But it may not bring users who stay long. CPA gives better results because you pay for real actions like signups or purchases. But, it takes time and costs more. In the end, CPC sends quick traffic and gives a wide reach. But you often pay for clicks that do not convert properly. Below are some detailed pros and cons of each stated mobile advertising strategy:
