Hello, @EstebanBalv903 . Those are great questions. My course, "Up and Running with Concurrency in Go", has only been up a month, but it's doing pretty well. Happy to share what I did / have learned:
1) My course was never free, but I set the original price fairly low, then I've been raising it occasionally.
2) Udemy has 2 options for FREE coupons: 3-days unlimited, and 31-day, limited to 10 redemptions. I used the 3-day unlimited on social media and got a good number of enrollments and ratings.
3) I thought about paid Facebook ads, but I got a large number by simply posting to relevant Facebook groups. Just be respectful of anti-SPAM rules on some groups.
4) Search Udemy discussions for piracy - there's a lot of good tips on this subject. This is one example that discusses what to do if you find your course on a pirate site: https://support.udemy.com/hc/en-us/articles/229604108-What-Should-I-do-if-I-Find-a-Course-on-a-Pirat...
5) Exercises are a good idea, whether or not they are a piracy deterrent. The biggest thing I learned from my early feedback is that my students wanted more exercises, so I updated the course and added lots of them.
Hope this helps and GOOD LUCK!
