With ARPDAU fitting more widely authorised as the actual metric publishers might be looking at, in app bidding contributed to massive ad income raises for publishers who applied this model. According to Jayme Farrell Ranker from MoPub, they’ve seen ARPDAU increases both across areas and across verticals – some publishers saw raises of 50% or more. Nimrod Zuta from ironSource highlighted the fact that even if publishers won’t see huge ARPDAU raises instantly away, the sheer discount in operational overhead will more than make up for the transition from waterfalls to in app bidding.
