Sub Domains

Subdomains can be a useful way for you to separate parts of your site if you need to.

Whether you want to create a site in a different language, target a specific audience, or create an eCommerce store, this can help you to do it.

What Is A Subdomain?

Subdomains are an extra addition to your main website name. You can create many subdomains for your main domain.

One example would be as the subdomain for

In the given example, 'website' is the primary domain and 'shop' is the subdomain. '.com' is, of course, the TLD (top-level domain).

You can select any word or text to be your subdomain, but make sure it's easy for your users to remember.

Why Use A Subdomain?

Subdomains are used to navigate to and organise the sections of your main domain.


The mobile version of many websites uses subdomains. This is useful for keeping the mobile site separate to the main one.

The mobile site will be different as it's been optimised for viewing on mobile, so many people prefer to keep this under a different domain name.


When you're in the process of creating a new website, you still want your old one up and running.

This way your customers can continue to access your site while you're building a new one. This is one of the most common reasons that people create subdomains. For example, they may create one that's called

This way you can create a new website and keep testing it until you're sure it's fully functional. Once you're happy with it and ready for it to go live, you can switch the domain name over to the primary domain name.


Another reason that many website owners create a different name for their website is for an eCommerce store that's attached to another website.

Many site owners prefer to create a subdomain for their online store because it's a more complex type of website.

Different Users

Many sites use subdomains to give their users separate site entry points. One example is on a blogging site such as Blogspot, where every blogger has a unique subdomain name. Eg ''.

Subdomains in SEO

Search indexes count subdomains as a different website to the main one. Each subdomain is crawled and indexed separately.

This means that any backlinks you've got on other sites only count for whichever domain or subdomain they link to.

You need to do SEO for any subdomain you have through keywords and backlinking just like you do for your main domain.

That's why most site owners only use subdomains if they are necessary. For example, if you're looking to target different groups or rank for different keywords.
