What is a Sub-Domain?

A sub domain, just as the term suggests, is a part of a larger domain and is dependent on the larger domain.  The rules that apply to sub-domains are rather different to those of larger domains.  For instance, for the case of the sub domains, there is a lesser likelihood of infringement. Basically, if you have your website out there on the internet and you have registered a legitimate and original domain, you can set up whatever kind of sub-domain you feel like since it would be a part of the long name.

The sub domain is linked to the primary domain and as such you do not need to have a new domain.  In other terms, a sub domain is much similar to a sub-directory, but rather that it appears after your domain name, it appears before the domain name.  Just like the case is for website directories, your domain name will be stored in the root folder of your primary website.

In most instances, sub domain names are usually free and again, you can come up with as many as you want to.  The good thing is that you don’t have to register them with your domain name registrar nor do you even have to renew them every other year.  Once you renew your domain name, they are automatically renewed in the process.

In order to set up a sub domain for your new website, you just have to log on to the control panel and make the necessary adjustments.  You can also use the account where you initially bought your domain when you want to make these adjustments.  It takes a couple of minutes and the good thing is that you won’t require to wait for any approvals from a third party.

Why make use of a sub domain?

The main aim of using a sub domain is to ensure that your files are well separated and neatly organized.  This might not always be essential if you are solely managing your website because you can still make good use of sub-directories which also work.  However, for larger corporations the use of sub domains normally comes in handy. This is because it helps them to ensure that every department is separate from the others.  It includes the various emails which are associated with either of the sub domains.

It is also important to appreciate the fact that sub domains are essential if a domain has got multiple users.  If in any case, each of the users would like to have their own profile, and be able to do their thing separately, the need for a sub domain would be eminent in such a case.

Many blogging platforms and website hosting service providers offer free sub domains once you sign up or set up an account with them.   This simply gives you your own blog or website but still your sub domain is linked back to the primary domain name of the blog service provider.

If you are a website owner, you can also make use of sub domains in order to direct users to affiliate sales pages.  This is much easier and shorter to remember, especially in the case where you want to create interest in beginners.
