CPI

Affiliate programs and networks that work with the CPI (Cost Per Install, a subset of CPA) payout model pay per each download and installation of a game, an app, or software. Such networks are a great choice for monetizing mobile traffic and in-app traffic, for example, within the dating, casino, or sweepstakes verticals. The CPI vertical is one of the oldest in affiliate marketing and it allows to monetize virtually any traffic source.
