The first step is to add the domain name you want to use a Secondary domain on your account. For more information, see Add domains.

Here's where our support department sees the most issues. To avoid these issues, remember that each website uses its own folder — the one specified when you added the secondary domain name.

Take a look at the following screenshot for more explanation:

The screenshot uses a Web Hosting account. If you use cPanel or Plesk, your file structure will look slightly different. For example, cPanel's Secondary domain names each have their own directory in the public_html. Plesk's secondary domain names each have their own directory in the hosting account's root.

To Upload to Your Secondary Domain

1. Connect to your hosting account, or use the FTP File Manager. For more information, see FTP: How to upload files.
2. Browse to the folder you selected in the Add the Domain Name Section. In this example, that folder is anothercoolexample.
3. Upload the files to that folder.

The files you upload to that directory should have an index file, which is what makes your website display. Usually, this file is called index.htm or index.html, but there are other valid options. For more information, see What file displays when someone browses to my domain name?

That's it. Remember, if you just added the Secondary domain name to your hosting account, it can take 24-48 hours before you can see your changes on the Internet.

If the domain name you added and hosting are in the same customer account, we automatically update the domain name's nameservers, so the website starts resolving in 24-48 hours.

However, if the domain name is in another customer account or if its registered elsewhere, you must manually update the domain name's nameservers (more info) or IP address (more info).
