Use your JekyllLMS site as a landing page and funnel for your paid Udemy, Pluralsight, or Teachable course.
Set free: false and add an affiliate_url to your course front matter:
free: false
platform: udemy
price: "$19"
affiliate_url: "https://www.udemy.com/course/your-course/"
The course detail page automatically shows an “Also on Udemy” button that links out with your affiliate tag — turning free readers into paying students.
