Every once in a while I'm playing with Udemy data and something interesting jumps out:
It's a tough world out there. At least it's tougher than it used to be. Not only is it harder to get reviews, but the reviews are often quite critical. Either this is just me or I'm not alone. Either way, best of luck with your own Udemy course efforts and I hope this information helps explain some things in your own Udemy world.
I’m wondering if any of the following has an effect
Those are just from from the top of my head.
I think Greg is right.
More content, higher quality is expected.
New review system will lower them across the board a little.
Older courses, if in spaces that have frequent updates, will rate lower.
P.S. All these guesses are enlightening and I'm seriously considering them all. But what I was originally looking for is if anyone else has done any data analysis in these areas to either support or refute my observation that Udemy ratings are dropping over all. Any Udemy employees want to comment? Thanks everyone for your thoughts and observations.
