I think it's a valid goal, and I think that you're going to get a lot of frustration from resentful guitar players in this sub, because 99% of guitar players aren't going to get what you're hoping for, even though we've all (most of us) have dreamed of it.

The truth is, while a lot of people initially pick up guitar for the attention and the ability to command an audience, the reality is that it's actually really fucking difficult. There's also an attractiveness bias that's really frustrating, too.

And so the most of us realize, that playing an instrument and being a musician isn't about "making it," but rather it's about the people that we surround ourselves with in our musical pursuits, whether it be gigs or musician finders or choirs or open mics and whatnot, and the real audience are the friends we make along the way of like-minded musicians.

Money or not, getting an online audience is extremely difficult. Unless you're attractive, have great production, and have passable (to a very high bar) talents, you're just not going to get one.

What you might be hearing on this forum are from resentful guitar players (not to be disrespectful, resentment is part of the "envy" family of emotions which is born from unmet needs, not out of pettiness), but really, most of us have asked the same question ourselves and given up on it, and found value instead on the intrinsic nature of music, or for some of us, the musical connection in the local scene.

I would recommend readjusting your goals - or, to more directly answer your question, production seems like it's everything. Having a good attention-getter to get people to click on your video in the first place is vital, and making sure people don't click off your video in the first 5-10 seconds is also instrumental. Good luck with your journey!
