InMobi offers different pricing options based on the kind of targeting you choose.
Appographic Targeting and Publisher Targeting campaigns are priced on a Cost Per Click (CPC) basis. InMobi provides a recommended CPC bid to start with. This bid is based on the competition in different countries and on devices targeted by the ad group.
This recommended bid is also the minimum CPC bid. That means that even though you can enter a CPC bid of your choice, you cannot enter a bid lower than the recommended CPC.
Automatic targeting uses a CPI (Cost per Install) goal based pricing.
Based on the number of countries you target, there is a Minimum Daily Budget that you need to allocate in to see optimal results for your ad group.
