subpages

Subpages are pages that reside beneath a parent page in a hierarchical website, wiki, or content management system. They form a hierarchy, where the URL or path of a subpage includes the parent page, creating a navigational and organizational structure.

In wikis such as MediaWiki, subpages are created by appending a slash and a name to the parent page's title, producing titles like "Parent/Subpage". In CMS platforms, subpages are often modeled as pages with a parent field, creating a tree-like structure; some static site generators use directory structures, where subpages live in folders.

Navigation and discovery: subpages are usually linked from the parent page, listed in menus, and visible in breadcrumbs and sitemaps. Proper internal linking helps users and search engines understand content relationships.

Advantages: clearer organization, scoped permissions, easier maintenance, and more meaningful URLs for local or topic areas.

Considerations: avoid excessive depth; plan slug conventions; ensure redirects if reorganizing; be aware of SEO implications and canonical URLs; ensure compatibility with site's navigation and search features; permissions can be inherited or configured separately.

Example: a site about a university might have a page "Programs" with subpages "Programs/Undergraduate" and "Programs/Graduate".
