One way to grow your app is to buy mobile advertising in a way sure to support your strategy and objectives. Up until now, the focus has been on performance and buying on a cost per install or a cost per action. But there is a better and smarter way. Our host Peggy Anne Salz from MobileGroove catches up with Sergey Grytsuk– Lead UA Manager at Playrix,a leading mobile game development company, and Mobile Hero recognized for his app marketing expertise–to discuss why marketers should switch to buying on CPM. You get what you pay for, and Sergey tells us why buying on CPM is the best (and cheapest) way to get quality traffic at low risk. Since marketers are paying for impressions, not actions, he says, it also rules out much of mobile ad fraud from the get-go.
