What is a Subdomain?

While searching for Domains for your website, you should know that a complete Domain name (unique website address) consists of protocol, subdomain, Domain name, Top-level Domain (TLD), subdirectory and path and page or file. 

However, within the Domain Hosting and structure, every component plays an important part, the same as the subdomain. So in this article, we will dive more into the subdomain, the different types of subdomains, and their benefits.

What Is The Subdomain?

A prefix to a root Domain is a subdomain. It functions as a subset of the primary Domain, enabling website owners to organise better and manage their content. 

Subdomains are mostly used to divide up and organise various website parts. This organisational structure offers several advantages and the capacity to manage various content categories more successfully. 

While still being connected to the main Domain, each subdomain is allowed to have its distinct content, design, and functionality.

Suppose you have a website with an Australian Domain like  “abcd.com” and the subdomain of this Domain could be “blog.abcd.com” or “shop.abcd.com.” In these instances, “blog” and “shop” are the subdomains, while “abcd.com” is the root Domain.
