Hello sir,
Here, I am ready for add advertisement in your application.
In ad mob 2-3 types of ad
Banner, Interstitial, Rewarded Video etc..
In banner, we can show ad in small area and our screen works as it is.
In Interstitial ads, that cover the interface of an app until closed by the user
Rewarded Video, full-screen video ads that users have the option of watching in their entirety in exchange for in-app rewards
So, which type of ad you want to add in application ?
And which type of application you have so we discuss that where and when we have to show ad ?
