Is it possible to install advertising from google, yandexa on a 2 level domain?

Question

contextual advertising

Good day. What is the maximum number of subdomains that can be created on one site? For example:
https://test.ru
https://blog.test.ru/
https://info.test.ru/
Is it possible to advertise on https://blog.test.ru/ and https://info .test.ru/ from different google accounts? Can anyone tell me approximately how much you can earn for impressions or advertising from google with a traffic of 1 million people?

Answer 1

As much as you want.
It is possible, but there is no need. Banally uncomfortable. It does not affect earnings. But it's hard to manage.
From 200 thousand to 1 million rubles approximately.
But before you reach this million, there are so many fakups waiting for you along the way .... In particular, supporting such attendance is not at all hosting for 120 rubles a month.
