How to set a bid according to you CPA goal

CPA goal represent the amount you are willing to pay for 1 conversion/install.

For each campaign you can expect a certain CR% (conversion rate) based on the targeting, type of offer, country etc. When setting the CPA goal, you need to take in consideration the bid you have set and the expected CR%. 

Here is a simple way to estimate the CPA goal:

Bid / Expected CR%= CPA


Bid is $0.02, expected CR 1%, CPA goal should be $2.

 Keep in mind that the bid should be competitive, and if you increase the bid, you should increase the CPA Goal respectively.


Bid is increased to 0.05, expected CR is 1%, the new CPA goal should be $5.
