How to monetize downloads?

Question

contextual advertising

There is a site in the bourgeoisie. Files on site. The files are poorly downloaded. There was an idea to create something like a file sharing service. Those. do not let the file download until the user looks at the advertisement ~60 sec. Profit!
The trouble is that adsense doesn't allow it as much as 2 times.

Publishers are prohibited from posting ads on support pages (login, logout, error messages, thank you, etc.). These are the sections of the site that visitors see when they are about to leave the site or when they take certain actions, such as a purchase or a download.

Publishers are prohibited from updating a page or page element without a user request. This includes, but is not limited to, displaying ads on pages or other placements with automatic redirects or automatic updates. Publishers also cannot set a timeout before showing content such as videos, games, or downloads and broadcast ads during that time .

What to put there?
PS Let me emphasize once again that the audience is English-speaking!

just read the reviews carefully and don’t put everything in a row - they will put encoders

Answer 2

Don't put adsense there. The story of any other banner network. Better than video ads. It would be just logical that before downloading a person should watch an advertising video.
Or monetize the files themselves by installing additional software. Affiliates like www.somotoinc.com
