What is a Sub Domain?
Well, in short a sub domain is a branch of a larger domain. You see subdomains all the time while you are online even if you do not know what they are called. URLs indicate a sub domain by a / and then the sub domain or by a word, then a period, and then the name of the main site. Good subdomains have names that are easy to understand and will make intuitive sense to the visitor. Sub domains are a great way to divide a larger site so that visitors can navigate it more easily. Some very large sites even use a sub domain ranking system in which they show the top visited sites on the main page so that people can visit those top subdomains quickly.
Free Sub Domains
Getting a free sub domain is one of the easiest ways to start a website. You can get free sub domain hosting by searching for sites that allow visitors to set up their own pages on the site. Free blogging sites work in this way, for example. One simply signs up and then creates blogs using free sub domains. You will be able to post, correspond with readers, and even make money by using free sub domain web hosting. This set-up is one of the ways in which you can begin a web business for no money. Using web sub domains, you can have affiliate links, contextual ads, and other forms of revenue generation on your site. You have no cost for domain name registration or hosting because your sub domain web site hosting handles everything for you.
Picking Sub Domain Names
The most important point to remember when working with web sub domains is that some sub domain names work better because they are easier for people to remember. Catchy phrases and clever spellings may seem cute on advertising, but they do not work well when you are creating a site that exists because someone is creating sub domain web folders on a much larger site. Others need to be able to remember the name of your site and the larger site, so picking a shorter name is one way to go. Instead of having people remember 50 or 60 characters, try to shoot for around 30. Also stick with words that are common because some subdomains are rarely visited because people do not know the meanings of the words in the sub domain.
