What is a Subdomain

Did you know you can use a single domain to create different websites? With a subdomain, users can set up multiple websites running simultaneously on the same domain.

Another way to do this is by using subdirectories. However, subdomains are the recommended choice because of their Search Engine Optimization impact.

What is a Subdomain?

A subdomain is an added part of the domain name, and it helps businesses navigate and categorize their website into multiple sections. Users can create different subdomains on their main domain with ease.

Subdomains come before the domain extension and the primary domain name, and it allows users to set up different websites using one domain. Also, users can use subdomains to launch a forum, support page, or career site, and they can use it to create localized content.

Businesses can use subdomains to set up blogs with different themes, and it allows them to create backlinks to their primary domain to increase authority. Search engines view subdomains as individual sites, thus increasing the chances of users getting more traffic.

How does a Subdomain work?

Everything from mobile phones to websites that connect to the internet has an IP address. The Domain Name System (DNS) is responsible for connecting users to websites using that IP address. It translates a domain name into its accompanying IP address used to locate and load up a website.

Subdomains, just like domains, are website addresses that the DNS translates into IP addresses. A domain consists of two main parts- the top-level domain(TLD) and the second-level domain (SLD), while the subdomain has a second name before the SLD.

Uses of a Subdomain

How can use a subdomain? It’s not just for building websites on an existing domain. So let’s find out.

To create an ecommerce store

Users use subdomains to run an ecommerce store that complements their primary website. Because ecommerce sites require a complicated setup, most companies prefer to have a separate subdomain for them. Besides, users use subdomains to expand their businesses without spending money purchasing additional domains.

For Search Engine Optimization (SEO)

With a subdomain, users can organize their website content to simplify the navigation for end-users. The better the customer experience on their website, the higher it will appear on the search engine page. Plus, subdomains enable users to set up backlinks to their main domain to increase their search engine optimization.

To set up a testing version of a website

Developers often use subdomains to test new updates and plugins before putting them live on the internet. Website designs and layouts evolve as time goes by, and subdomains enable users to test their new content structure before publishing on their leading site.

To target a variety of audiences

Businesses use subdomains to target different audiences — this way, they can get their products or services to the right people. For example, a furniture business can use different subdomain URLs to focus on different types of customers.

To develop a mobile version of their website

Most businesses use subdomains to create mobile-compatible versions of their website. This mobile site version enables companies to please their mobile audiences and increase their reach.

To create a blog or publish alternate content

Subdomains enable users to create any blog while associating it with their main domain. They also help users who want to publish ideas separate from what their website represents.

How to Create a Subdomain

A domain is needed to set up any subdomain, and once users purchase a domain, they have the rights for the subdomain. With the Scala Hosting platform, users can create a subdomain with ease.

Using Control Panel is one of the most popular hosting panels used to create subdomains. The steps to create a subdomain are highlighted below:

Give the subdomain a name

Users need to think and choose a name for their subdomain before they create it. Some popular subdomains include support, help, blog, shop, events, and store. Additionally, users need to choose a name that describes that part of their site and using one word is usually best.

Access the Control Panel

Users need to log into their Scala Hosting account to access their Control Panel known as SPanel, and then choose the primary domain.

Navigate to subdomains to create one

Users need to find the subdomains option and click it. From there, they can choose a name for their subdomain and select the domain they want to add it to.

Set up a new DNS record

After creating the subdomain, users need to create a new domain name system record. They have to navigate to DNS, click on Add, and select the subdomain they want to connect with.

Set up a site to the subdomain

Once they have resolved the subdomain, users can add it to their site. Subdomains can work as a new website even if it shares the domain with other sites.

Subdomain Vs. Subdirectory

Subdomains and subdirectories both achieve the same end-goal — setting up multiple websites within a single domain. However, search engines view both of them differently– they view a subdomain as a different website and view subdirectories as files under the main domain.

Small businesses with limited resources can opt for subdirectories. On the other hand, companies with resources can use subdomains for multiple uses.  Scala Hosting offers users free DNS management, Email forwarding, and Domain forwarding when they register their domain names.
