Root Domain

Categories: R, SEO Glossary

The Root Domain represents the uppermost level in the hierarchy of a website’s domain structure. It is the core domain name that precedes the top-level domain (TLD) — such as .com, .org, or .net — and is followed by a period. This foundational domain encompasses all associated subdomains and subdirectories. For instance, in ‘’, ‘example’ is the root domain and ‘.com’ is the TLD. Subdomains, like ‘’, and folders within the site, such as ‘’, all fall under the root domain’s umbrella.
