Key Difference Between Subsite and Site Collection in SharePoint

When it comes to SharePoint, the key difference between a subsite and a site collection lies in their scope and scale.

Focus Keyword: SharePoint Site Collection vs Subsite

Subsite: A subsite is a smaller entity within a SharePoint site. It is typically created under a parent site and inherits permissions, settings, and navigation from the parent site. Subsites are ideal for organizing and managing specific projects or departments within a larger site structure.

Site Collection: In contrast, a site collection is a standalone entity with its own set of permissions, settings, and navigation. It has its own top-level site and can encompass multiple subsites. Site collections are more robust and independent, suitable for distinct teams, divisions, or business units that require separate customization and security boundaries.

Therefore, the key difference can be summarized as the scope and autonomy of a subsite within a parent site versus the self-contained nature of a site collection encompassing multiple subsites.
