What is a Subdomain?

A subdomain is an internal branch of a website that operates under a main domain. It helps organize and separate different sections of a site without needing a completely new domain name. Businesses and website owners use subdomains to create distinct areas for blogs, support pages, or different versions of their sites while keeping everything under one brand.

Subdomains make it easier to manage content and to improve user experience. Additionally, subdomains help with the search engine optimization (SEO) of the entire website. Subdomains are especially useful for large websites that need separate sections for different functions, such as an online store or a customer access portal.
