What is a sub-domain name

A subdomain is a domain that is part of a larger domain, known as the root domain. It is used to organize and structure the content of a website by creating separate sections or areas with unique web addresses. Subdomains are created by adding a prefix to the root domain, creating a different URL.

For example, in the URL "blog.example.com" "blog" is a subdomain of the root domain "example.com". Similarly, "store" is a subdomain in "store.example.com".

Key features of sub-domains include:

• Organization and structure: Sub-domains allow website owners to organize different sections or types of content under a specific sub-domain. For example, a website can have sub-domains for a blog, e-commerce store, support portal, or any other specific section.
• 
  
• Autonomy: Sub-domains can function independently to some extent, with the potential for unique content, design, and functionality. This autonomy is useful for managing different elements of a website separately.
• 
  
• URL hierarchy: Subdomains are part of the larger URL hierarchy and appear before the root domain. They are separated by dots in the URL structure.
• 
  
• Technical implementation: Subdomains are created through Domain Name System (DNS) records. Each sub-domain can be associated with a specific IP address or directory on a web server, allowing the hosting of different content.
• 
  
• SEO impact: Sub-domains can have an impact on search engine optimization (SEO). Search engines may treat subdomains as separate entities, which can affect the way they index and rank content. This may be beneficial for websites with diverse content or specific functionality.

Examples of sub-domains include:

• blog.example.com
• shop.example.com
• support.example.com

Unlike sub-domains, subdirectories are another way of organizing content within a website. Instead of creating separate subdomains, subdirectories involve placing content in folders under the root domain (for example, "example.com/blog" or "example.com/store"). The choice between subdomains and subdirectories depends on factors such as website structure, content organization, and SEO goals.
