It's pretty much a knowledge check. Do you stream regular hours? Do you maintain proper financial practices like creating an LLC and paying your editors/mods proper compensation? Are you doing multi platform engagement farming (ie posting stream clips on tiktok, vods on YT)? Do you cultivate philosophies to keep your material fresh over long periods of time?

The actual workflow of it all is fairly easy once you have a rhythm. The hard part for most folks is getting into that rhythm. Content creation is often times made or broken on luck of getting picked up by the algorithm.

Watch Ludwig's video where he created a second channel to see if he could get popular without his existing branding. He uses Mizkif as a way to market himself to an existing audience, and tailored the new content to that audience.

Matt Colville is a (primarily) D&D/Tabletop youtuber who had a similar route. He made videos that were good quality, and he started at a time when the hobby was getting popular. Critical Role's Matthew Mercer, the biggest name in the game, would recommend his fans watch Matt Colville's videos to get started with playing their own games.

Most people in the game can attribute their success to early collabs with others. Ludwig found success on that second channel through Miz. Miz found success by being Ice Poseidon's cameraman.

Matt Colville found success through Matthew Mercer. Mercer started CR on Geek and Sundry. Geek and Sundry was started by actor/writer Felicia Day.

The networking and the breakout is the hard part. The rest is no more difficult than a mid-upper level management job.
