Hi @zoyaali0904 Welcome to the community! In your instructor dashboard, you'll find a tool called "Insights" here. This tool uses a few different factors to gauge the opportunity on each topic, it considers how many students are searching for courses on the topic, the number and the quality of available courses, and the conversion rate for the topic, so it can help you understand how your course’s trends fit into the bigger picture. Also, you can check a few courses to see how they have been created.
I hope this helps!
