What are Subdomains?

A Comprehensive Guide;

There is a need to understand what a subdomain is? Subdomains are the part of the URL structure that lies before the first dot. Their primary function is to organize a directory of the different content sections on your website. They are primarily used for creating other separate stores, shops, blogs and forums, for example, World.economy.com. IN these URLs, the world is a subdomain, the economy is the second URL, and “com is the top-level domain.

For better understanding, I will try to describe every detail precisely.

Difference between a subdomain and a domain.

Both domains and subdomains are part of the website URLs. The main difference between them is which one is used at which time and for what purpose. An environment also acts as a root domain when there is a matter of website creation. It plays a magic role in converting your IP address into an easily memorable one. In another way, we can say a domain is what people usually write in the browser’s address bar for the searching website. Additionally, a subdomain is also a part of the central domain functioning for organizing data files in précised way.

Here we are explaining structure-wise of both and try to highlight what differences are between them;

As we already know, WWW is a subdomain and is commonly used. It has a specialty and cannot be used as an ordinary one. There are also found fully qualified domain names (FQDN), consisting of hostname and domain name.

What is the usage of subdomains?

As being used mainly for site organization, there is also numerous usage of subdomains. You can create a subdomain for performing several other tasks as well.

  • Testation of the new site: The facility of building and editing a site without putting the primary domain on maintenance mode will add value by not disturbing the central area.
  • Launching of different language versions; You own the facility of launching different websites in different regions of the world, irrespective of the fact they have other languages. for exe, pak.yourdomain.com, for Pakistan.

    Uk.yourdomain.com is used for the United Kingdom.

  • Better organization of site; Having a subdomain can help you manage and support your audience in different ways, such as customer support, FAQ, documentation and community.

Creation of sub domain;

You have generously obliged to create as many subdomains as you need that may exceed a hundred. The word press hosting shared plan gives you the choice of creating in bulk. There are primarily two ways of creating a subdomain that is in use; via a control panel or the DNS on your hosting account. Remember one thing you must already take the domain name for creating a subdomain.

Creating subdomain via h Panel:

Creating a subdomain via h Panel must point your domain to Hostinger. in case your domain is registered to another registrar, you must follow the following instructions to indicate it on Hostinger.

Go to your CPanel dashboard, scrolling down to the domains section. Click on subdomains. Here you must enter your intended subdomain and click on create. You can also tick on the custom folder subdomains box to complete the specific custom directory. Once it is done, a pop-up right on the corner will appear saying “subdomain created successfully” there, you will also get a list of available subdomains if needed; any select otherwise delete it. Furthermore, you have to install the platform you want for subdomain usage. For this purpose, you may need WordPress.

Go to the website tab on the left menu bar and start by clicking on Auto installer. Select word press as your platform for your subdomain.

Here you need to fill in the form to install word press on your subdomains;

  • Select the subdomain of your choice.
  • Put in your login credentials.
  • I am adding website title.
  • Language selection.

After filling out the form, you click on install. It must take a few minutes, and your subdomain will be listed there.

Remember that creating a subdomain needs an entry on your DNS zone and takes 24 hours for activation.

  1. creating a subdomain DNS zone;

Hostinger offers two options for creating a subdomain. I have mentioned the first method briefly and the second one via DNS zone editor. Scroll down to your CPanel dashboard and select DNS zone editor. Fill in all the required criteria for a new DNS record.

  • Type; Selecting A from the menu as a subdomain using A record to point out an IP address.
  • Naming;  Change it as you intended to change, for example, filling in “gallery” for creating gallery.yourdomain.com.
  • Pointing to;  Filling into the IP address of your hosting account.
  • TTL;  (time to live)this setting tells you how long DNS will resolve cache information before requesting a new one.the default setting is 14,400.seconds

When all this is done, you may now hit Add card, and then you may see the manage DNS record below under your new domain. You will also find a name (canonical name) recorded for the subdomain “WWW”, unlike A document pointing to the subdomain. For example, if someone is typing the URL https://itupdown.com/, it will direct to itupdown.com instead of showing a page error. After completing the process, it will take approximately 24 hours for activation.

Subdomain creation via subdirectory;

It is a pretty similar process to a subdomain. The subdirectory is used for organizing your content better way, First, clearly know what difference lies between them.

  • Subdomain: blog yourdomain.com
  • Subdirectory: yourdomain.com/blog 

Keep in mind a subdomain’s purpose is creating another website for data files you ultimately accessed and redesigning the interface without affecting the leading site and domain name. The subdirectory is part of the website and is a subfolder of the site’s file. The best example of a subdomain is support.zyro.com and learns fiverr.com.

Subdomain vs subdirectory for SEO;

It has become widespread debate whether subdomains and subdirectories perform effectively for SEO. This is because search engines, especially Google, treat subdomains as a separate territory from the original site, so its ranking will be done differently. These subdirectories help with crawling and search engine consideration in finding as this section is also a part of the leading site. 

Using the best setup that may not create a problem is desirable and running perfectly for a long time.


It is clear that subdomains are part of the main domain and are used explicitly for inter-sectioning the site content. You may also create a subdomain for the test site to offer unique and exclusive content. It can also help publish content in multiple languages for a better user experience. A domain can be created through the DNS zone and via cPanel by following easy steps .you own the choice of creating various parts on the leading site under the main domain, which entirely depends on hosting provider capacity. Keep in mind subdomains are slightly different from subdirectories. The difference between them must be clear, and choose them accordingly.
