A subdomain allows you to create a completely separate website structure under your primary domain, like `blog.yourdomain.com` or `shop.yourdomain.com`.
How to Create a Subdomain
- Go to Websites & Domains.
- Click the Add Subdomain button at the top.
- Type the prefix you want to use (e.g., "blog") in the Subdomain name field.
- Select which parent domain it should be attached to.
- The Document Root will be automatically generated (usually `/httpdocs/blog` or similar). This is where you will place the files for the subdomain.
- Click OK.
Plesk will automatically configure the DNS records and create the necessary folder structure. Wait a few moments, and your new subdomain will be ready to host a new application or WordPress instance!
