Choose a memorable Domain name. If you're launching a new site, choose a name people will remember easily.

You may not wish to go to such extreme lengths, but at least ask yourself:"Will people remember my domain name?"At my four main sites, a large percentage of the visitors are people who have remembered the domain name and typed it directly into their browser.

Try to choose a name which won't be confused with similar names. You don't want people typing your competitor's domain name when they’re trying to find your site.

NameBoy.com has a handy tool to help you choose domain names. Also,you can find a surprising number of good deleted and expired domain names
at Whois.net.
