Free sub domains.
Having
free sub domains is like having free additional websites. For example, if you
had www.yoursite.com you could also have www.sub1.yoursite.com - www.sub2.yoursite.com
etc etc.
A sub domain is just like having a separate website and you control them via
our easy to use control panel. Another great thing about sub domains is that
search engines consider them to be a separate website. For example, if you had
www.yoursite.com you could also submit www.sub1.yoursite.com - www.sub3.yoursite.com
to the search engines as well, resulting in even more hits to your site.
