Subdomain Definition & Meaning

What Is A Subdomain?

A subdomain is a separate section of a website that uses a prefix added to the domain name. Subdomains act as a completely separate website but are hosted on the main domain.

Subdomains can be used to create multiple website versions in different languages, separate a blog from the rest of the website, or set up multiple stores on an eCommerce website. As a result, subdomains do not contribute to the root domain’s authority; it acts as a completely separate website.

There are no restrictions regarding the number of subdomains website owners can create on the same domain. However, each new subdomain requires separate SSL certificates because it functions as an independent website.
