How to add another domain to your hosting area.
Log into your cPanel using the User Name and Password allocated
Select Addon Domains, enter your domain name and password.
Video Tutorial
An addon domain allows you to reach a sub-domain when entering the name of the addon domain into a browser.
This means that you can host additional domains from your account, if allowed by your hosting provider.
Addon Domains Subdomains are relative to your account's home directory.
Note: Your add on domain must be active to your hosting space before you can add it.
(ie the DNS should point to your SmallPond Hosting space.)
UPLOADING A NEW WEBSITE
You can FTP or use the cPanel File Manager to upload content to your Addon Domain website.
Use the FTP login for your main account - details in you account activation email.
Open the Addon Domain folder and upload your website files.
Note that the home page should be called either index.htm, index.html. or index.php

Google indexing of the add-on domain is not as effective as having a website working off one domain.
