Everything about a site is content.  It is data and metadata.  All items are to be considered content.  Links, images, documents, text, HTML, XML and blogs are all examples of content.  It is helpful to consider every object as a type of content.  Content will all be defined by types.  Content types will also include complex collections of types such as a contact item which often includes name, address, phone, email and more.
