What is Subdomain

A subdomain is a part of a larger domain name and is used to organize and navigate to different sections of a website. It appears before the main domain name and is separated by a dot. For example, in the URL blog.example.com, “blog” is the subdomain, “example” is the main domain, and “.com” is the top-level domain (TLD).

Key Points about Subdomains:

1. Structure: A subdomain is structured as subdomain.domain.tld. You can have multiple levels of subdomains, like sub1.sub2.domain.tld.
2. Purpose: Subdomains are often used to create distinct sections of a website, such as:
   • shop.example.com for an online store.
   • blog.example.com for a blog.
   • support.example.com for a customer support section.
3. Independence: Subdomains can be treated as separate websites with their own content, settings, and even different hosting environments if needed.
4. SEO: Subdomains can affect SEO differently from subdirectories (like example.com/blog). Search engines may treat subdomains as separate entities, which can impact how authority and rankings are distributed.
5. DNS Configuration: To create a subdomain, you need to configure the DNS settings of the main domain, adding a new DNS record those points to the appropriate server.

Advantages of Using Subdomains:

• Organization: Helps in organizing content and services more logically.
• Targeting: Allows targeting different audiences with specific subdomains.
• Performance: Can improve website performance by spreading load across different servers.

Examples of Usage:

• Geographic targeting: us.example.com, eu.example.com
• Different services: mail.example.com, ftp.example.com
• Staging environments: staging.example.com, dev.example.com

Using subdomains effectively can help in managing large and complex websites more efficiently.
