As you may know, each year Udemy hosts a massive 'BlackFriday' sale. Typically around the 2nd or 3rd week of november (still to be announced 2019) udemy invests a lot of money in advertising and marketing. So if you are considering creating a course this year, why not set you deadline in time for black friday.
One thing you need to keep in mind is that you will want to have your course finished and submitted and hopefully approved a week or two earlier than the actual sale. You will want to get some initial traction so that the clever computer bots will flag your course as having potential. You can do this by getting a bunch of students yourself within the first few days/weeks.
If you have been putting off creating your course this year. Now is the time to stop procrastinating. Lets make a stand and set a date!
Looking forwards to hearing your commitments below. I will be there along side you creating a few more courses myself. Good luck my friends.
