Author's description:
In the analysis, you can have general views of Udemy courses and how they generate revenue and subscriptions. It is an effective analysis for products, sales, and subscriptions. It answers questions:
- How do revenue and subscriptions change yearly?
- Current period vs. the same period of last year?
- Which are the most welcome or less welcome courses? And what is the relationship between price, course duration, review, and subjects?
- For each category, what are the courses about, shown with main keywords?
- How is the performance of free/paid course? etc.
It is user-friendly with a clear user guide and apps like interface.
