What is CPA?
CPA means “Cost Per Acquisition”. It is a metric calculation used to measure the actual cost per install/conversion compared to your investment goals.
The calculation formula is: Campaign Spend/Conversion = CPA
Why is it useful?
The CPA goal enables us to optimize your campaign towards it.
It is also used to analyze your ROI in our reports.
How to use CPA goal feature?
Define your ROI goal
Insert the CPA goal under the bid and budget section in the campaign settings.
For example, in the screenshot below, the CPA goal is $2.
Once you insert the CPA goal value, optimization will be enabled by default.
How to set a bid according to your CPA goal
CPA goal represents the amount you are willing to pay for one 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 consider the bid you set and the expected CR%.
Here is a simple way to estimate CPA goal:
Bid/Expected CR% = CPA
The bid is $0.02/the 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.
The bid is increased to 0.05, the expected CR is 1% = the new CPA goal should be $5.
Enable StartApp optimization towards the CPA goal
By enabling this option, we will optimize the campaign to meet the CPA goal.
You are required to implement StartApp postback for enabling CPA goal optimization. Learn more about how to implement our postback here.
If you do not enable this option, you will still be able to see and analyze the CPA goal in the reports. However, we will not take it into consideration in the optimization process.
