SitePoint.com has an excellent article on choosing the right domain name that’s worth your time to read. There is also another other factor to consider as well. Make sure that your site’s keywords, the two or three words that best describe the purpose of your site, are contained in the name if possible. This will make it easier for you to easily tell other people what your website name is and it makes your site show up better in search engines like Google. For example, if you sell plumbing supplies, the obvious name would be bobsplumbingsupplies.com. If you can’t get all your keywords in your name, consider using simple words in connection with one or two of your keywords. Although it won’t rank as high as a pure keyword domain name, it’s still easier to tell people what your domain name is. Nameboy.com is an excellent service that helps you find the right domain based on their keywords that you should help you find the right name for your business or organization.
