A subdomain is a child address that lives under your main domain, such as blog.example.com or shop.example.com.
Key Points
- Subdomains help you separate sections of a website without buying a brand-new domain.
- They are often used for blogs, client portals, support centers, regional sites or development environments.
- A subdomain can point to different folders, servers or applications depending on how your hosting account is configured.
- Search engines can treat subdomains as distinct sections, so structure and internal linking still matter.
- Use subdomains when you need clean separation and use subfolders when you want one tightly unified website structure.
Frequently Asked Questions
Is a subdomain free?
Most hosting control panels let you create subdomains without buying another domain, provided you already own the parent domain.
Can a subdomain have its own website?
Yes. A subdomain can run a totally different site, app or service from the main website.
Does a subdomain need DNS?
Yes. The subdomain usually needs a DNS record so that browsers know where to send visitors.
