On the Internet, your domain name is your unique identity. Having your own domain name, website and email addresses will give you and your business a more professional look. Another reason for a business to register a domain name is to protect copyrights and trademarks, build creditability, increase brand awareness, and search engine positioning.
A domain name can be any combination of letters and numbers, and it can be used in combination of the various domain name extensions, such as .com, .net and more. The domain name must be registered before you can use it. Every domain name is unique. No two websites can have the same domain name. If someone types in www.yourdomain.com, it will go to your website and no one else's.
