Content types allow standardized metadata, templates, and workflows across libraries. They ensure that documents are tagged consistently, making search, reporting, and automation more efficient. Proper use of content types reduces errors, improves organization, and ensures compliance. Implementing content types systematically helps maintain structured content management, enhances collaboration, and makes it easier for teams to locate and use documents effectively. Content types work in both SharePoint Server and SharePoint Online, although some automation features may be limited in on-premises environments.
