I'd like to start creating courses on Udemy but my area of expertise is extremely competitive and there are already a number of excellent courses with thousands of enrollments.
I have no following on any platform. Would it be better to start creating content for Youtube to learn how to create good content, learn what people want, and hopefully build a following before investing significant time in creating a Udemy course that might not sell?
If your course is not selling well the. You can run facebook ads or youtube ads so you can boost your sales on udemy.but if you are planning of starting a youtube channel with out having any following on any of the social media then it is harder in youtube too.
If your niche has more competition then better option is to find an another niche that can make you happy.
