Why Create Online Courses?
Online courses are one of the best ways to monetize knowledge. Unlike 1:1 consulting or live workshops, courses are scalable - once created, they can be sold to unlimited students with no additional work.
What Makes Courses Different
- • Sell to 1,000 students with the same effort as selling to 1
- • A $50 course with 200 students/year = $10,000 passive income
- • Record once, earn for years
- • Startup cost: $0-50 (free recording software + optional mic upgrade)
- • Introverts welcome - screen recordings beat live presentations
Platform Comparison
| Platform | Revenue Share | Best For |
|---|---|---|
| Udemy | 37-97% | Beginners - has built-in audience |
| Skillshare | Watch time based | Creative topics |
| Teachable | 95%+ (you pay platform fee) | If you have your own audience |
| Gumroad | 90%+ | Direct sales, simple setup |
Recommendation: Start with Udemy. It has millions of students actively searching for courses. Once you build an audience, consider self-hosting on Teachable for higher margins.
Choosing a Profitable Topic
High-Demand Categories
- • Tech & Programming - Python, web development, data science
- • AI & ChatGPT - Hottest category in 2026
- • Business Skills - Excel, marketing, project management
- • Design - Photoshop, Figma, video editing
- • Personal Development - Productivity, communication, career
How to Pick Your Topic
- • Search Udemy: If 10+ courses exist with 1,000+ reviews, there's demand
- • Read 1-star reviews of competitors - what are students complaining about?
- • Your "boring" day job skill might be gold (Excel, SQL, project management)
- • Avoid pure trend topics - "AI Prompt Engineering" will last; "How to Use GPT-3" won't
