Cost per click or CPC is a pricing model used in all forms of digital marketing, including app user acquisition campaigns. In this model, app advertisers pay publishers each time their ad receives a click.
By using a CPC model, app marketers are able to focus on acquiring an engaged audience while controlling advertising costs. However, clicks don’t guarantee conversions, so it’s vital to regularly monitor and refine CPC campaigns to achieve the desired results.
Cost per Click is calculated by dividing the total advertising spend by the number of recorded ad clicks.

For example, if an app advertiser spends $1500 on an ad campaign and receives 6000 clicks, the campaign’s CPC is $0.25.
