What is the cost per in-app ad impression on the AdMob and iAd networks?

Question

Android

Since there are many advertising networks, I ask you to limit yourself to AdMob and iAd in view of their popularity.
The following indicators are interesting:
The cost of one ad impression in ios
The cost of one ad impression in Android
Does the cost differ depending on the country?
What is the average duration of 1 show?

Answer 1

1. Cost refers to clicks, not impressions. And the number of clicks depends on many things - what kind of application you have, the location of the advertisement, its size.
If you have the Camera app, it's clear as day that users logged into it, took a picture and left, no one will click on ads.
2. Yes, very dependent on the country. Sometimes the cost of a click differs tenfold.
3. You choose the duration yourself.
