Every organisation has differing types of content.
SharePoint manages this by using Content types. A content type consists of a metadata profile, information policies (such as retention), and a template.
Carefully planning and content types can dramatically improve your SharePoint implementation. the search engine will pick up metadata properties, and give users the option to refine the search results based on these same values.
Content can also be easily standardised – by defining document templates for each content type. Each document can then take the same look e.g. the header, first page, footer, index, can be defined in the document template stored against the content type.
Content Types are hierarchical and inherit elements of configuration. A carefully planned hierarchy will dramatically reduce the administrative overhead.
