One thing that's worth mentioning is Udemy is a completely different type of company based on you being a watcher of courses vs being an instructor on Udemy.
I was an instructor there for 5+ years (with ~30k enrollments) and in my entire professional career I've never met a worse company in terms of how corrupt they are and how little they actually care about instructors unless you happen to be one of the few instructors they reach out to privately and sign a contract with in which case they do extra things for you like promote and rank your course more so than related courses in your category. Their entire platform is based on manipulating both instructors and watchers of courses.
I would seriously suggest anyone thinking about creating courses to avoid using any type of course marketplaces (ACG is especially bad too). It's worth it to build your own audience because on Udemy and other platforms you're actually not building your own business, you're building their business because you won't receive any information about anyone who signs up which means your students are 100% locked into that platform. If you leave you're essentially starting at ground zero in which case you might as well start at ground zero on your own terms.
