Which domain name should I register?Written by Tom
If you are looking for a domain name for a website, or if you want to invest in domain names, it can be difficult to figure out what to register. There are so many domain name extensions. What is a domain name extension? A domain extension, or tld (top level domain), is final part of a domain name, part that comes after dot on right. Examples of common domain name extensions are .com, .net, .org, .info, and .biz. These are also called gtlds (generic top level domains). So, for example, with domain name somename.com, somename is name and .com is domain extension (tld).
There are also country code top level domain extensions (cctlds). Some examples of these are .us (USA), .cn (China), .in (India), .de (Germany), and .co.uk (UK). .TV (Tuvala) is also a country code extension but it is often sold as a general tld.
The most common and well known tld is .com. .Com was first extension to be used extensively by businesses online. It is considered by many to be king of all tlds because of how recognizable it is, clout it's use offers and because it is extension most likely to be typed-in (people will actually type .com domain name in their browsers to go directly to site even if they are not familiar with an actual site that may be there - this is free traffic in a sense). This can occur because people may assume all sites end in .com or that .com somehow is part of any name or it can occur due to "bleed" from other tlds - people see a name with some extension and when they go to look for it or type it in, they put .com instead. For many, .com truly is internet.
.Net has generally seen less use than .com, but many still consider it to be second most valuable extension. Many isps do use it. .Org is used by many non profits, various organizations and government related sites. Considered by some to be second or third most valuable tld, in terms of recognition and resale price level. .Com, .net and .org are original general use internet tlds. They are sometimes collectively referred to as CNO. They have been with us since mid/late 80's.
Proffiting from domain investmentWritten by Dorry Mitchell
If you have a domain name that you are not using, or a site that you have to take down for some reason, then traffic that goes to that site is doing you no good at all. Instead of leaving domain blank, or letting your hosting company (Like GoDaddy) get free publicity on your page, you can make money off your pages by letting a domain parking company place ads on your page that will be displayed to any visitors. You still own website and domain, you just let them put ads on pages for however long you want.
