This is a brand new rich result for websites that offer online or offline educational courses. Only educational content that fits the following definition of a course is eligible for the Course info rich result: a series or unit of curriculum that contains lectures, lessons, or modules in a particular subject or topic.
You can help people find your course content by telling Google about your course using course info structured data. When you provide more detailed information about a course, such as reviewer ratings, pricing, and course details, Google can better understand your course and present a rich experience to people with the course info rich result.
