Don't make your Udemy courses free!!!
If you release a course as free you may lose track of how many time you've gone between free and paid and lose your Udemy promotional announcements. That's a disasster!!!
Instead, always release your courses as paid and distribute free coupons to get students. Don't make your course free!!!
Well, you see... one thing just leads to another!!!
Personally, I price all of my courses at $199.99 so that they will be the greatest marketed down course when the course sells for about $9.99 (I make about $5.00 on average on all course sales).
There's lots more I could say (and will say, if you ask ;-).
But I think that's enough for now.
