Sites published with Scroll Viewport use human-readable and SEO-friendly URLs that can be customized to a degree. The URL is constructed as follows:
Site URL: This URL segment is a unique string of URL-safe characters. It is chosen upon site creation and can be changed in the site settings.
Viewport URL: All Scroll Viewport sites carry this segment in their URL.
Content source path: This segment is a string of URL-safe characters and must be unique per site. Upon site creation it is set to a default value (space key) and can be edited from your site’s content source table.
Page title: This part is the URL-safe version of the page title with Confluence page ID appended.
Only the page ID is used to direct a request to a certain page, meaning already shared links to newly renamed pages will remain accurate.
