The first type of free domain name is known as a third level domain name. This is a domain name that is commonly distributed by free web hosting companies or affiliate programs. Yet, there is a downside to this type of domain name. This downside involves the first level domain name, (usually the company's name), having to be a part of the third level domain name. For example, consider a website created with Geocities. If a webmaster chooses 'web hosting' as their third level domain name, the following would be the syntax: Geocities.com/webhosting. Such a domain name is not very convenient for potential visitors, so webmasters may want to consider redirecting these types of URLs to other versions of free domain names. The second type of free domain name is a first level domain name that contains an extension that is not as popular in the Internet world. Examples are the types of free domain names offered by Dot.tk or Free Domain.co. The extensions offered from these companies are .tk and .co.nr, respectively. These are far from a .com or a .net, but they are not as cumbersome to use as a third level domain name. The main key is going to be making sure the initial domain name is short and easy to remember, so potential visitors won't be as offset by the unusual extension. Finally, there are free domain names with extensions that are more commonly used such as .com or .org. To find these a person has to do some sleuthing. Sometimes individuals will offer them for free, since they were about to expire anyway. A person can try to find these situations through message boards dedicated to webmasters. Other times companies will offer these types of free domain names because they are getting free ad space. What happens is every time the free domain name is used, a pop-up ad will show up on the person's website. This is how the free domain name company gets their revenue. In conclusion, free domain names can be an excellent alternative for someone needing domains for several websites. The best ones are those in which a person can get a first level domain, though a third level domain name is better than nothing. To sign up for a free domain name, one can search for free domain name companies on the Internet.
