This is the new strategy now, all of the students with low review scores are enrolled in a bunch of classes they have never ever started taking. I emailed Udemy and actually have proof that they are sending trolls on purpose. Udemy has partnered with companies specifically to do this. So you log in and see that maybe a student has watched your course in 5 minutes!!! Lol, timestamps are correct and if you noticed they have never even taken the course THEY ARE ALLOWED TO PUT A BAD RATING WITH NO COMMENT. That's the game Udemy does. They encourage spam, 0% courses taken and speed though fake students. They want and need this, they believe their research proves that DRAMA makes a good marketplace for them. We are in a sort of teenage Facebook here. Other Instructors will try to attack me here so be prepared for the bullies to come and respond and start insulting me and referring me to their "Top Instructors". They will be ignored and I am leaving this up for everyone to see. I've been fighting this high school strategy on Udemy for quite a while now. Trust me IT'S REAL.

The number of students a course or instructor has is a completely unreliable measure of how they are actually doing in terms of making money (which is why most of us are here). The number of reviews tells you how many "real" students are going through the course and that equates to the amount of money being made because those who review are almost always real students. I have checked this with a number of successful instructors. Generally, real students will review a course at the rate of 1/3 to 1/4. In other words, if a course has 1000 reviews you can assume that the number of real students who have paid for the course or are actually going through the course (UFB) is somewhere between 3000-4000. If it shows that they have 10,000 students you can assume that the instructor has given away between 6-7000 free courses or coupons. You can also assume that the instructor has made $11 X the number of reviews, approximately (NOT the number of students). This varies by topic. When an instructors promotes him/herself by claiming they have a huge number of students, check the number of reviews, multiply by 3 and subtract that number from the claimed number of students and you will have the official BS factor for that instructor. High BS factors also correlate with LOWER ratings. Instructors with cleaner number have higher ratings. For example, I do not give away any free courses and only a very few 10-20 coupons when I launch a new course. Checking this morning I have 182,312 students, 62,361 reviews, and I have earned a total of a little over 700k. You can do the multiplying and dividing. I understand the desire of new instructors to offer free courses to establish "social proof", but it is only social proof to those who don't understand the numbers and I seriously doubt it has much impact on sales. There are better ways to create sales, but they take more effort than just offering courses for free.
