Every application contains at least one site. For example, the Discover reference application contains the Discover Electronics web site. Experience Manager supports applications that can contain multiple web sites using a single index. Each web site in the application can have its own unique set of pages and data. These sites are sometimes known as storefronts or webshops.

Your development team creates sites in the application. These sites are collections of content and features that an end user experiences through a unique base URL. This URL might contain a unique domain or a unique path within a domain. Site filters can be used to limit the display of data to subset of the index for a particular site. You can create and manage specific pages for a site with Experience Manager while also sharing elements of the experience.
