Understanding Subdomains: The Basics
Subdomains are essential components of a domain hierarchy. They allow website owners to create distinct sections or branches within their main domain. For example, if a company owns the domain “example.com,” they can create subdomains like “blog.example.com” or “store.example.com” to organize and manage different parts of their online presence.
What Are Subdomains?
Subdomains are prefixes that precede the main domain and are separated by a period (dot). They are used to categorize and structure a website’s content.
Why Are Subdomains Important?
- Organization: Subdomains help in categorizing and organizing website content, making it easier for both website owners and visitors to navigate.
- Control: They allow for separate configurations and permissions, enhancing security and management.
- SEO: Properly structured subdomains can positively impact search engine optimization (SEO) efforts.
