The subdomain is very familiar to web managers. However, it might not be that popular with newcomers and people who are starting their online business. Today we will help you with this topic about what is a subdomain.

A subdomain is a separate domain that belongs to a larger domain name in the Domain Name System (DNS), like an additional part of your site’s domain name. It is made for people to simplify the process of creating a more impressive website domain name or specific content. The main domain can carry a lot of subdomains to navigate to different parts of the site.

For instance: m.facebook.com. As you can see, “Facebook” is the domain, “.com” is the domain extension, and “m.” is the subdomain. The subdomain’s usage is various; it’s based on the purposes of web managers and hosting companies.

Subdomain’s Use Incidents


Mostly, companies will use subdomains for web testing or open beta version of a site. They are used when web managers want to make a trial run on new plugins and functions. The site will be tested on the subdomain site before they deliver the updates to the users and visitors.

There are many cases that companies use them for their site’s mobile version such as m.facebook.com or location-related ones like foody.com.vn. This purpose is called building up sub-sections.

Users may use subdomains to make a place for a bunch of people on your web such as user.website.com. This is how many famous web platforms provide sites for users to access. Usually, the subdomains will serve different types of visitors.

Almost every e-commerce store is very hard to build up, so corps will choose subdomains as an alternative method for that. The method is that those companies will create a separate subdomain for handling deals and negotiations.

WordPress can be applied on the subdomain as an independent establishment from your main site. You may use subdomains to arrange your site more conveniently. Although it won’t affect the efficiency of SEO, you’d rather keep all the information on the same domain. Using subdomains for public websites is not suggested, either.

subdomain vs subdirectories

Subdomains and subdirectories are 2 different services, and so are their purposes. Let’s go through the importance of selection between those 2 services. The search engines look upon them differently, and that brings particular affections on SEO.

Subdirectories are located in your primary domain’s files. Once scanned through, the search engines don’t recognize subdirectories as separated files, so the SEO is divided between domain and subdirectories. It’s better for new online shops and bloggers as it helps them get their sites high-rank quicker than subdomains do.

Unlike subdirectories, subdomains are easily separated by the search engines. The subdomains are dug carefully and gone through each one. The SEO is not shared between subdomains and domains, so building up the rank for the subdomain’s keywords is very challenging.

The subdomains are advised to be only applied if you have a clear and fair enough reason. The difficulty of subdomains’ rank rising is as difficult as the process for an entire website.
