CPI boost rules

Using our CPI boost rules, you can improve targeting of your promotion campaigns. The CPI boost rules let you increase or decrease your CPI bid for specific users. In this way you can bid more for users that matter to you, and bid less for users that are worth less than average.

How does the CPI boost rules work?

You can increase or decrease the CPI (cost per install) bid in your campaign settings for specific types of users. This increase or decrease applies to your original bid for each country in the selected campaign.

For instance: if you bid $1 for an install of your app, a CPI boost of 25% will result in a bid of $1.25 for the defined types of users. A CPI decrease of -50% would result in a CPI bid of $0.50.

There are four different types of users for which you can increase or decrease your CPI bid:

  1. Users of an app type: a rule of this type applies to users using either an app or game when he sees your promotion campaign.
  2. Users of apps within an app category: a rule of this type applies to users who are using an app in a particular Google Play category when they see your promotion campaign.
  3. Device age: this rule applies to users whose device has a certain age (<1, <3, <6 and >6 months), based on the earliest installed app on the device.
  4. Device type: this rule applies to users of a particular category of device (small screen phone, phone, tablet).

Different boosts may apply to the same user. For instance if you set a boost of +10% on games, and also a boost of -25% on small screen phones, and your CPI bid is $1.00 in the country of the user, the CPI for a user who is using a game and has a small screen phone will be $0.82 ($1.00 * 1.10 * 0.75 = $0.825).


The CPI bid can not be boosted higher than 2 times the original amount, and can not be boosted lower than the minimum CPI bid of the country. For example, if you have an original bid of $1 for the United States and there is a negative boost of 50% applied to a user, the new CPI bid for that user will not be $0.50, but $0.80, as this is the minimum CPI for the United States.

Go to your campaign setup and click the advanced panel to open it.


In the advanced panel, click on the “+CPI boost rule” button.
