trying to learn to develop a hybrid app. I want to learn how to implement specific ads on the application using adMob.
As I've found out, adMob only promotes other people's apps. Is there a way to promote a specific ad (kinda like promoting/sponsoring), like a product or company?
I recommend you to use a plugin like https://github.com/appfeel/admob-google-cordova.
Then in your admob account just setup a banner with no mediation and publish the ads you want with your own internal campaigns. There is no cost on this.
