Your unique domain name gives you several advantages:
1) It increases your name recognition and allows your friends, family or customers to remember more easily how to find you and your site.
2) It gives you a more serious and professional “appearance” on the Net.
3) It helps brand your image and adds a level of trust and integrity to your site.
4) It helps people find you through search engines.
5) Nobody else will get the name that you need.
6) It gives you a permanent “anchor” for your Internet identity.
7) E-mail addresses hosted in association with your domain name will not change, even if you switch ISPs.
