What Are Subdomains & How to Use Them


What is a Subdomain?

The subdomain is part of the additional information added at the beginning of the website domain name. Allows websites to classify and organize content for a specific activity – such as a blog or online store – from across your website.

A subdomain allows you to split sections of your site-wide enough to authorize their dedicated section without having to deal with the hassle of setting up a new domain with a new domain or confusing visitors with a completely different domain.

With a subdomain, you create a unique website where you can use a different website theme in terms of its appearance, menus, and functionality. Because a domain and a subdomain function as two separate websites, they are also tracked separately. This allows the business to provide unique user information and more accurately track user data and statistics, which can be used to improve and enhance both the primary URL and subdomain.

For example – store.yourwebsite.com

In this example, ‘store’ is the subdomain, ‘your website’ is the main domain and ‘.com’ is the main domain (TLD). You can use any text as your subdomain, but you want to make sure, It is easy to write and remember.

Now, As you understand, What are subdomains in web hosting? Now, Let’s know about Wildcard Subdomains in short. 

What is Wildcard Subdomain?  

The Wildcard subdomain allows you to identify all sub-domains that are not in a specific folder in your account. It means that if you add different subdomains (not created in your cPanel) to your browser, they will all display the same content you uploaded to a folder set in the wildcard domain.

Use Cases of Subdomain

The most widely used domain setting is to create a test version or platform for a website. Developers will usually check for new WordPress plugins and updates on the subdomain site before publishing them live online.  

Another common use of a subdomain is to create an online eCommerce website. Usually, companies are looking for a different subdomain that will handle transactions because eCommerce sites often require a more complex setup. 

We have also seen companies use subtitles for their mobile websites (m.yoursite.com), site-specific sites (uk.yoursite.com), and create website sections.

Other uses of the following domains are:

  • Create different language versions of the website (en.yoursite.com).
  • Create a mobile version of the website (m.yoursite.com).
  • Set up a network of unrelated sites. For example, how to sign up for a WordPress.com account and create your blog in a subdomain (yourblog.wordpress.com).

These are a few reasons why you use a subdomain for your website.

What is a subdirectory?

The subdirectory is a type of sub-domain domain that uses folders to organize content on a website. The subdirectory is like a small folder and the words can be used interchangeably.

In the URL, the subdirectory comes after the root directory or domain name. For example, the root directory of a company is company.com. So, the URL below the list may be company.com/products. Or it may be as complex as company.com/products/pricing.

When it comes to subdirectories, think of a structure resembling a breeding doll. Each folder can be built into the other almost permanently. That means you can have a subfolder inside the subfolder until you have a pile, which is probably hundreds, of deeper layers.

Too many layers of subfolders can be a nightmare for SEO. The URL series gets long and confusing, user information is compromised with every click you take to get to the next piece of content, and search engine searchers will find it almost impossible to crawl your site to find new content and other  SEO winnings you can do.

On the other hand, sub-folders can be good for SEO as they retain any backlinks obtained, domain authority, and page authority tied around the root domain. And if the site is easy to navigate, URLs are shorter and simpler, like company.com/careers, which means you can market specific web pages or predict pages with their URLs without confusing your audience.

Difference Between Subdomain and Subdirectory

A subdomain separates your website so you can create certain types of content that are different from your root domain. On the other hand, the sub-directory is the way within your site. Subdirectories are the internal level of a domain.

Technically, a website can use both a subdomain and a subtitle structure. Sub-domains will usually have at least a few subfolders within them to organize the content, but not as many as the subdirectory. That is because there is a small variety of content covered in the sub-domain of the root domain with subfolders.

Therefore, it is important to understand what the main structure of your website will be. To determine this, let’s take a look at how sub-domains and sub-domains affect SEO.
