Time for an update:
Earnings have been around $20-30 in advertising per day. On the App Store I got some more in-app purchases. In total it was around $60 for app-purchases for November.
Since Google Admob removed the ad limit (took 2-3 weeks) from one of my accounts, I updated one app from Appodeal to Admob (it was running with Unity and Facebook) and what can I say? The eCpm jumped from around $3-4 to $7-8.
Usually Facebook Audience Network is fine, but the fill rate has been 70% for me for most of the time. This already means: 30% less income plus: eCpm is a bit lower than for Admob. Especially for iOS. The eCPM for the iOS apps have been around $1.50 which is really low.
I never implemented Unity ads in one app alone, always used it with mediaten/appodeal, therefore I can't really judge it. But from what I see the eCPM is fine and the fill rate has been 100% (I didn't send to many requests tho).
Appodeal: Thats something weird. I have the feeling I am earning much less with Appodeal, than what I would earn from Google Admob alone. Mostly it shows me a 50-60% fill rate even tho I added 3-4 ad networks. However, in the ad networks themselves they show me a 100% fill rate.
So, you guys know I don't really like Google Admob, because they are limit accounts and do whatever they wanna do, but honestly: The eCPM is the best. The fill rate is the best. Absolutely no doubt.
About the Apps:
No app or account has been removed since my last update. I will upload another Android app later today. Also, I will make another iOS app. I will monetize both with Google Admob only (for now). I should scale it up and upload more and more apps.
Also:
I am thinking about upload my Android apps to different stores: Huawei App Gallery, Amazon App Store, Samsung Store for example. Just giving it a try.
