A subdomain is an additional part of a website’s main domain that helps organise content. It appears before the main domain in the URL, like ‘blog.example.com,’ where ‘blog’ is the subdomain. Subdomains are used to separate different sections of a website, like a blog, store, or help centre, while still being part of the main site. They allow businesses to manage content separately but under the same overall brand.
