How to add ads in andoid unity app?

Question

Unity

I’m trying to make an advertisement in the application, I’m watching video lessons, unfortunately the lessons are already outdated because a lot of things have been updated, changed, I looked for something newer, but they don’t really tell anything like in the old ones, so far I’ve encountered a difference
using UnityEngine.Advertisements;
using UnityEngine.Monetization;
They are connected for advertising, but what's the difference?
In general, is there a ready-made mini example where they tell what is how it is arranged or works, otherwise my brain is already boiling to understand what and how?

Answer 1

Do not do this! Games without ads are better. If you don’t even have the mind for this, then the game definitely sucks and you don’t need ads in it. The output will still be zero.
