I analyzed a bunch of top selling Udemy courses and found something interesting
A lot of highly rated programming courses on Udemy haven’t actually being updated frequently despite major ecosystem/framework changes over the years.
The old ratings still keep those courses at the top, which makes it hard to know what’s actually up to date. Also, course creation dates aren’t directly shown on the website, so it’s easy for beginners to miss how old some courses really are.
In order to solve this problem for myself, I built a small Chrome extension that displays the course freshness based on the course creation as well as the updation date.
The freshness score is shown directly in the search results, so users don’t have to open and check every course individually. This has been helpful for me for filtering out outdated courses.
If anyone’s interested, I’d be happy to share it, just leave a comment.
