How to Add Subdomains and Multiple Websites on Hostinger

As projects grow, so does the need for separation. Blogs branch off. Landing pages spin up. Client sites multiply. Hostinger is built to accommodate this growth without forcing premature upgrades or convoluted configurations.

This guide explains how to add subdomains and manage multiple websites on Hostinger cleanly and safely.

Understanding Subdomains vs Multiple Websites

Before configuring anything, clarify intent.

A subdomain:

  • Exists under a primary domain (e.g., blog.example.com)
  • Shares brand authority
  • Is useful for content separation

A separate website:

  • May use a different domain
  • Has its own files and configuration
  • Is operationally independent

Hostinger supports both scenarios well.

Adding a Subdomain on Hostinger

From hPanel:

  1. Navigate to Domains
  2. Select Subdomains
  3. Enter the desired subdomain name
  4. Assign it to a directory

Hostinger automatically handles DNS configuration for internal domains.

When to Use Subdomains Strategically

Subdomains work best for:

  • Blogs
  • Knowledge bases
  • Region-specific content
  • Campaign microsites

They are less ideal for unrelated projects.

Adding Multiple Websites to One Hosting Plan

Depending on your plan, Hostinger allows multiple websites under one account.

To add a new website:

  • Assign a new domain
  • Create a separate directory
  • Install the desired platform (Builder or WordPress)

Each site remains isolated at the file level.

Managing Resources Across Sites

Multiple sites share hosting resources.

Best practices:

  • Monitor resource usage
  • Avoid unnecessary plugins across sites
  • Upgrade plans proactively when needed

Growth should feel smooth, not constrained.

SSL and Security for Subdomains and Additional Sites

Each subdomain and website requires its own SSL certificate.

Hostinger provides free SSL, but:

  • Enable it for each site
  • Verify HTTPS individually

Security does not automatically inherit.

Common Configuration Mistakes

Avoid:

  • Mixing files across sites
  • Forgetting SSL on subdomains
  • Treating subdomains as disposable

Structure early prevents cleanup later.

Final Editorial Take

Hostinger’s multi-site capabilities scale quietly. You are not forced into complexity until you need it.

When you treat each site or subdomain as a deliberate asset rather than an afterthought, Hostinger’s structure supports growth instead of resisting it.
