I've been thinking about how to monetize the game I'm building and AdMob seemed like the obvious candidate. I checked a bunch of sources including Youtube videos, blog articles and reddit posts, and stumbled across a whole bunch of apps that got their ad serving limited because of "suspected click fraud". Most of those apps have in common that they are relatively new and had massive download spikes thanks to ad campaigns. Obviously that was a massive red flag for me, but the search for alternatives gave me a good impression on how massive Google actually is. Many developers don't even seem to consider any alternatives for AdMob/AdSense. So far the best alternative I was able to find seems to be MoPub and to use their mediation capabilities. I really don't want to go all in on Google, but especially when working on mobile, it often seems like there are not too many choices.
