Hi, i thought about uploading my game and i really dont know nothing about ads.
How can i know how much i earn for every ad? How much i get for an ad that fully watched and ad that skipped after 5 seconds?
Ads that keep beeing watched by the same player will profit less money?
Is it ok to play my game through my phone and watch my ads?
Where can i get all those answers?
Thanks

During development you should use test mode, after release if you are playing as any other “normal player” you can watch real ads. As any other ad network we have mechanisms in place for detecting fraud, but as long as you are acting as “human” there should be no problems.
Hope it answered your questions.
