Unlisted courses
Hide a course from every listing page while keeping its direct link purchasable.
On a course's Visibility & search tab, turn on "Unlisted" to remove it from your school's homepage, course catalog, sitemap, and instructor page — anyone who has the direct link can still view and buy it, but it won't be discoverable by browsing your site or through search engines (the sales page is marked noindex).
This is different from a hidden pricing tier (see "Early-bird, presale, and hidden pricing") — a hidden tier hides one price option on a course that's otherwise publicly listed, while unlisting hides the entire course from discovery. Use unlisting for things like a private cohort, a course you only share with a specific list, or content you're not ready to publicize yet but still want to sell via a direct link.
