When you share your mini-course with a link on your socials (Facebook, LinkedIn, etc.) a social preview will be seen. This preview is formed by the title and description of your mini-course.
You can see this preview under Settings > SEO.
To change the social preview of your mini-course, you can edit the title and description under SEO settings. The description is only visible in the social preview of a mini-course and in the collection landing page of the mini-course. Additionally, it affects the SEO score of your mini-course. Find out more in SEO Settings.
To change the image shown when you share your course on social media, update the course thumbnail. Click the three-dot icon on the course card, then select Change thumbnail.
