Hello,
We would like to block ad serving from a certain country in one of our apps. So far we have tried several workarounds to minimize ad serving - but none work 100% of the time:
1) Create a mediation group for that country and ad units and set eCPM to the max value - 1000$: still some impressions and clics are being registered.
2) Set the minimum eCPM of these ad units to 1000$ for that country:
still some impressions and clics are being registered.
3) Block ads by not requesting them if Android TelephonyManager returns that user is in that particular country: still some impressions and clics.
So how can we 100% block an ad unit to answer ad requests just a certain country or group of countries?
It would be truly helpful to do this from our Admob Control Panel.
