- Point multiple domains/sub-domains at a single WordPress installation and maintain link integrity (i.e. if you're on http://foo.com, links will be http://foo.com/bar, and if you're http://baz.com links will be http://baz.com/bar)
- Overwrite site title, description, or theme per domain
- Customize content per domain using the [MultiDomain_if] and [MultiDomain_else] shortcodes
If you need more customization between domains, WordPress MU is a better option.
