CPI (Cost Per Install) is a metric that shows the acquisition cost of users that installed your app. The advertiser is charged a fixed or bid rate, but only when the app is downloaded, installed and opened.

AppBooster offers the one stop mobile solution for media buyers and allows to buy rewarded and premium traffic directly from multiple display advertising marketplaces all around the world.

Rewarded CPI Campaign
Rewarded CPI campaign is good for app soft-launching, enlarging user bases and testing Click-to-Install conversion rates. In general, buying volumes of cheap installs may lead to higher rankings and visibility of your app on the app store, and as a result it helps generate more organic traffic and increase app’s page views. AppBooster allows you to buy large numbers of rewarded installs and helps you hit all these goals.

Premium CPI campaign combines a risk free CPI (Cost per Install) model and powerful mobile display advertising connected to 100+ trusted publishers, networks and SSPs. Our in-house smart bidding technology enables you to buy display ads in real-time marketplaces. No incentivization is used across premium publishers, you acquire real users who are likely to show higher loyalty and engagement in your app, comparing to Rewarded CPI.

It depends on what type of CPI campaign you choose on the AppBooster to advertise your app.

In case you choose Rewarded CPI campaign, you do not need to use creatives since this type of campaign will use incentivized sources, meaning that users will be rewarded for downloading and installing your app.

Premium CPI campaign requires you to upload creatives (banners in JPG or PNG) that will be used across premium sources (platforms, direct publishers, networks) to buy media, with absolutely no incentivization. Depending on sources, your creatives will be placed on web sites and mobile apps. Creatives shall be designed and formatted according to IAB Display Advertising Guidelines.

Running campaigns

When all the settings are ready, you can either start the campaign immediately or schedule it for a certain day and time.

The CR or conversion rate is the proportion of users who install an app to users who have tapped on app advertisement. An install is considered a conversion: (Conversion / Clicks) x 100 = CR % AppBooster cares about the advertiser's productivity and quality of campaigns promoted on the platform. All of the campaigns are required to have at least a 20% CR. In case of a continuously low CR, all the advertiser’s campaigns will be permanently stopped.
