So I have this software. It loads up to a website. It gets downloaded a few hundred times a day. But all my users are cumulative. The person who opens my software today, will say the same page he did yesterday. The software's grown to at least have 100k downloads. Out of which, I'd expect half of those users to be regularly using the software. That's about 50k cumulative monthly users. Can I make money from cost per impression? I can put some ads on my software?
