Subdomains let you create separate sections of your website using the same domain name. For example, you can have:
Subdomains are useful when you want to organize different parts of your site without buying new domains.
This guide explains what subdomains are, how they work, and how to set them up step by step.
What Is a Subdomain?
A subdomain is a domain that is part of a larger parent domain. It acts as a separate address but shares the main domain.
Example:
yourdomain.com blog.yourdomain.com → subdomain
You can use subdomains for blogs, stores, forums, support centers, or any distinct section of your website.
Why Use Subdomains?
Here are some benefits of using subdomains:
✔ Organize content into separate areas
✔ Run different applications on the same domain
✔ Test new site versions without affecting the main website
✔ Improve user navigation and structure
Subdomains are flexible and easy to manage from your hosting control panel.
Before You Start
Before setting up a subdomain, make sure:
✔ The domain is already added to your hosting account
✔ DNS is correctly configured (propagated)
✔ Your hosting plan supports subdomains
How to Set Up a Subdomain (Step by Step)
Follow these steps to create a subdomain:
Step 1 — Log In to Your Control Panel
Sign in to your hosting control panel using your credentials.
Step 2 — Go to the Subdomains Section
Find and open the Subdomains tool under the Domains section of your control panel.
Step 3 — Enter the Subdomain Name
In the subdomain form:
Subdomain: Enter the name (e.g.,
blog,shop, etc.)Domain: Choose your main domain from the dropdown
Document Root: The folder where your subdomain will store its files
By default, the control panel fills the document root for you. You can change it if needed.
Step 4 — Click “Create” or “Add Subdomain”
After entering the details, click the button to create the subdomain.
Your new subdomain will be set up and ready for use.
Upload Files to Your Subdomain
To publish content on your subdomain:
Go to File Manager or connect using FTP
Navigate to the subdomain’s folder
Upload your website files there
Once the files are in place, your subdomain will display your content.
Install Applications on a Subdomain
You can install apps like WordPress on a subdomain using your one-click installer:
Choose the subdomain from the installation dropdown
Continue with setup steps as usual
Each subdomain works like an independent site.

✔ Blog: blog.yourdomain.com
