A subdomain is a section under your main domain (kompaniyam.uz). Example: blog.kompaniyam.uz for a blog, shop.kompaniyam.uz for an online store, admin.kompaniyam.uz for an admin panel. Subdomains can be used as separate sites, each with its own theme, design, and content.
Subdomain vs addon domain
Subdomain β a section of a single domain: blog.kompaniyam.uz. Addon domain β a separate, independent domain: blog.uz. Subdomains are free (you only need hosting); addon domains require buying a new domain.
SEO-wise: Google treats a subdomain as a separate site β domain authority is built independently. This is bad for a blog (the main domain's authority doesn't grow), but good for a separate product or e-commerce store (cleanly separated from the main business).
Creating a subdomain in cPanel
1. cPanel β "Domains" β "Create A New Domain" or "Subdomains" (older cPanel). 2. Subdomain name (e.g., "blog"). 3. Domain (pick the main domain). 4. Document Root β auto-filled: public_html/blog/. 5. After clicking "Create" the subdomain is ready.
Add a new site β upload your files into the public_html/blog/ folder or install WordPress there via Softaculous.
DNS is auto-configured
When you create a subdomain via cPanel, the DNS A record is added automatically (blog.kompaniyam.uz pointing to the IP). No extra configuration needed. The subdomain works immediately.
If you use an external DNS provider (Cloudflare, Route53), you need to add the A record for the subdomain manually.
SSL for subdomains
Let's Encrypt covers subdomains automatically (cPanel AutoSSL). After creating a new subdomain run "Run AutoSSL" or wait (it runs automatically every 24 hours).
Subdomain usage scenarios
For blogs β blog.kompaniyam.uz (but for SEO a /blog/ subdirectory is usually better). For e-commerce β shop.kompaniyam.uz (but if it's the main business, /shop/ is better). For admin or staging β admin.kompaniyam.uz, staging.kompaniyam.uz. Multi-language sites β uz.kompaniyam.uz, ru.kompaniyam.uz, en.kompaniyam.uz. For APIs β api.kompaniyam.uz. For email β mail.kompaniyam.uz.
Subdomain SEO tips
If you want to build your blog under your main business's authority, use a subdirectory (/blog/) rather than a subdomain. On a subdomain blog authority builds separately and doesn't help the main domain.
A subdomain is good for positioning as an independent site β for example, for a separate product launch.
