Domain Names
The selection of domain names is a major consideration when doing business online, and it is often one of the first issues to be addressed. While a good domain name won't guarantee success, it can have a positive (or negative) impact on almost every aspect of online business.A "good" domain is one that is easy to remember and minimizes confusion. If you are acquiring a name that has the potential to cause confusion, it is generally recommended that you obtain the most logical variations This often includes non-hyphenated and hyphenated variations, along with words that are phonetically similar and common misspellings.
New types of domains are being released all the time, including .biz and .info.
The very first use of domain names, and still one of the best, is for email. Without domain names sending email is almost impossible.
A good alternative are International Keywords , which work in a similar way.
