I Love YTtalk
It sounds like he has traffic from other sources (not YT) that he wants to drive to Youtube and make it profitable. That traffic, apparently, is 20-30 yo men. He can have a separate channel with content that is focused on that traffic, I don't see a problem with that.Forget the demographic
Girls. Girls will be the most common interest among most of that traffic. Figure out something with some kind of sex appeal but that will still allow monetization (not really easy but possible). Unless you have a different way of monetizing the videos, in which case you can make the content a little less family safe.I have traffic for YT videos from men over 20-30 years old and older (all the world).
