How can I promote my YouTube channel without spamming or annoying people?

[David Zajac]

I've had a YouTube channel for awhile, and want to get my channel more noticed by a larger group of people. I am willing to do a lot of work on my channel, because I know good quality is the key to success, but I need a way for people to discover my channel without advertising in comment sections, spamming inbox's, etc. I don't want to do that because it is annoying and is taking advantage of people, which I do not want to do. I would rather have 10 subscribers that actually watch my content, than 50 subscribers who watch the first minute of my videos or are not involved at all. Any advice?
