Difference Between Domain and Subdomain | Domain vs Subdomain

In the internet world, the terms domain and subdomain are often confusing to many people. Although both are closely related, the difference between domain and subdomain is significant to understand, especially in managing and optimizing websites. 

In general, a domain is the main address of a website, while a subdomain is an additional part of the domain that functions to create a separate part of the same site.

Through this article, you will get an in-depth explanation of the differences between domains and subdomains, including definitions, functions, and the roles of both in professional website management. Check out the further discussion below.

What is a Domain?

Domain is a unique address used to identify a website on the internet. Functioning as a digital identity, domains make it easy for internet users to access a particular website by typing the address in a browser. Examples of popular domains include google.com and facebook.com, which clearly show the name and identity of the company.

The main function of a domain is to make it easier for users to remember and access websites without having to memorize complicated IP addresses. Domains also function as brand identities that are very important for the trust and credibility of online businesses. For example, a domain like example.com reflects the professionalism of a company or organization.

Domain types vary based on the extension or top-level domain (TLD). Some of the main types are:

• Generic Top-Level Domains (gTLDs) such as .com, .net, and .org.
• Country Code Top-Level Domain (ccTLD) such as .in for India, and .us for the United States.
• New gTLDs like .blog, .app, and .shop.

What is a Subdomain?

A subdomain is a special section of the main domain that serves to organize and divide the content of a website. Providing further structure, subdomains are often used to create separate areas of a site that can be accessed through a unique name that begins with the subdomain. For example, docs.google.com is a subdomain of google.com that focuses on documentation.

The main benefit of subdomains is that they make content management easier and improve user navigation. Subdomains allow you to manage different parts of your site separately without having to buy a new domain. For example, blog.example.com can be used for a blog, while shop.example.com can be used for an online store.

The types of subdomains are based on the specific needs of the user or website. Some common subdomains include:

• blog.example.com: for blog content.
• shop.example.com: for online stores.
• support.example.com: for customer support services.

Difference between Domain and Subdomain

The difference between domains and subdomains can be seen from various aspects. A domain is the main address that is fully owned by the site owner, while a subdomain is just a part of the domain. Subdomains provide more structured and frequently used content management at no additional cost, unlike domains that require registration and purchase.

1. How to Get a subdomain

Domains need to be registered through a domain service provider, requiring a verification and purchase process. A lot of domain providers like Godaddy, Bluehost, hosting, etc. provide a variety of TLD options at varying prices, and the purchase process is quite simple. Subdomains, on the other hand, can be created directly through the domain settings panel on the hosting without additional costs or special verification processes.

2. Price of a subdomain: difference between domains and subdomains

The price difference between domains and subdomains is very clear. Domains require annual purchases and renewals, depending on the TLD chosen. For example, .com or .id usually have a certain price that must be paid annually. Subdomains do not incur additional costs other than hosting and the main domain, making it more economical to divide content in a structured way.

3. Function

Domains serve as the primary identity and address of a website. They play a role in branding and make it easier for users to remember the site address. Subdomains serve to divide content and organize different parts of the site. For example, subdomains can be used for blog areas, online stores, or customer support, optimizing user navigation.

4. Impact on SEO

The difference between domains and subdomains in terms of SEO is quite significant. Domains have stronger SEO potential because all content is optimized in one main address. Subdomains, although they help with content management, are often considered separate entities by search engines, so they require a special SEO strategy to keep subdomains relevant in search results.
