问题
I have developed this game and published this in Play store. Drifter.IO
I have set up AdMob mediation for my earning purpose and integrated other 3 ad network apart from AdMob. Following image explain this clearly:
As per you see in the above image, I am getting really low Fill Rate in all ad networks so I am losing many customers request without any advertisements display.
So my question is, what is the solution for this purpose? How can I increase my ad network Fill Rate?
Provide your side suggestion or experience to me so I can apply and test.
