Location of an entity on the Internet.
There are different levels of domains.
Examples of the various levels are as follows:
Top-level (TLD) – .com, .net, .org, .edu, .gov
2nd-level – business, shopping, search
(2nd-level may contain letters, numbers, and hyphens)
3rd-level – www1, www2, keyword (optional)
(NOTE – make sure your site resolves with or without www)
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.
