Definition: Subdomain

« Back to Glossary Index

A subdomain is a separate part of a website that operates under a different URL, but is still part of the main domain. Subdomains allow website owners to create different sections of a website, each with its own unique content and structure.

For example, consider the domain “example.com”. A subdomain for this domain could be “store.example.com”, “blog.example.com”, or “help.example.com”. Each of these subdomains would have its own separate content and URL, but would still be part of the main domain “example.com”.

Subdomains are often used to separate different types of content or functionality within a website. For example, a subdomain could be used to host a blog, an online store, or a help center. Subdomains can also be used to provide a separate, more branded URL for specific content or functionality, such as a company’s career site.

It is important to note that subdomains are treated as separate entities by search engines, which can affect the search engine optimization (SEO) of a website. Therefore, website owners should carefully consider how they use subdomains and whether they are the best solution for their specific needs.
