As stated earlier, stats like number of users enrolled, completion rate of course, recent renewals/purchases let you analyze what works best for the website and what doesn’t, and capitalize on the information.
LifterLMS does course reports really well. Apart from number of courses and general figures on the dashboard, course stats can also be viewed under analytics. Here you can see reports for individual courses, with respect to parameters like all students, current students, completion rate etc. Other plugins for short in terms of inbuilt capabilities for reporting. Courses in WP Courseware have a gradebook each, which contains basic stats like number of users and progress for each user.
While the base plugin for LearnDash has no reports for per course, it does have an extension called the LearnDash ProPanel which brings per course reporting right to your back end, complete with graphs and pie charts.
