I read through Google Mobile Ads SDK document online . There, it provides the guidance of how to use AdMob , Ad Exchange & DoubleClick for Publisher(DFP).
But, after read those guidance, I am really get confused about the differences among them. I feel they are almost the same for my mobile Android app. Could someone please make me clear about the most primary differences among these three?
As long as I know, there is one SDK, and 3 different ways to get ads.
AdMob manages investors for you and you get paid for views and clicks. DFP gives you a container for ads, but you have to find companies that pay for them. Ad Exchange (I'm not sure) lets you trade your ads for others'.
