Add subdomains in Sitejet

This article will show you how to create subdomains if your domain is registered with Sitejet. If your domain is registered with a third party, there is an additional step: you will also need to set an A record for any subdomains you create. Our article on connecting third-party domains will show you how to set the necessary DNS settings for a subdomain. Otherwise, the instructions below still apply.

Basic knowledge

URLs are made up of three parts: the subdomain, the domain, and the top-level domain (TLD).

The domain is the part of the URL that contains the website name. For example, in the case of "", the domain is "your-website". 

The "Top Level Domain" (TLD) was originally meant to indicate the region in which the website is located. For example, for Germany this is ".de", for Italy ".it", for Spain ".es", and so on. Now, there are more TLDs that have nothing to do with the region, such as ".com" (commercial purposes). Generally, when people are discussing a particular domain, the TLD is included anyway even if it isn't technically part of the domain.

Subdomains are the part that comes before the actual domain. Nowadays, websites are often accessed without the "www.", but strictly speaking the "www." is a subdomain. There are many other common subdomains that you will be familiar with. For example, if the domain of your company is "", you could create the following different subdomains:

  • "services." -> ""
  • "contact." -> ""
  • "info." -> ""
  • "my." -> ""
  • "partner." -> ""

Each subdomain is assigned to a specific subpage of your website that is pulled up when you navigate to it.

Sitejet uses the "my." and "partner." subdomains for white labeling. Therefore, we recommend that you do not assign your own subpages to these, or other subdomains used by Sitejet, which include "api.", "cms.", "preview.", and "preset.".

In addition to the settings in Sitejet described below, an A record is required in the DNS settings of your domain, which points to our server as it does for "www". The DNS record for the subdomain "services" might look like this:

Name                         Typ TTL Host/Value
services CNAME

Subdomains in Sitejet

If you want to create a subdomain in Sitejet, you can do so in just a few steps.

Click on "Pages" in the top navigation. On the right side, you will see the view described in the article about adding navigation.

Subdomains in Sitejet

From this view, you can either create a new page or make an existing page accessible via subdomain.

To create a subdomain, proceed as follows:

  • Click on the cog icon and the downward arrow for the relevant page to show further settings. 
  • The default value "www" is already entered in the "Subdomain" field. If you now set this to the desired value, e.g. "blog", then that page will become accessible by navigating to

Special case: Set up only the subdomain at Sitejet

There are several reasons why you might want to leave your domain for your website with another hoster and just set up a subdomain with us. This is of course also possible. The following steps are necessary. 

Please note: Of course "subdomain" is only a variable for your desired page. 

  1. First, you set up the domain in the Domain Manager. Please follow the guide "Activate a redirect". Sitejet will then recognize the domain and assign it to the corresponding website. You can now set up the appropriate subdomain. Please do not change the DNS settings for the domain at your third-party provider. 
  2. Now set up your subdomain exactly as you want it, as described above. Please create a subpage for it and make sure that the "Home" page remains with "/". Your home page can even exist completely without content. After the setup only the subdomain is accessible. 
  3. Once this is done, switch to your domain hoster. Here, you set the appropriate CNAME for your subdomain. 
Name                         Typ TTL Wert/Host/Value
subdomain CNAME 3600
This is how the settings should be shown in the CMS:

Your domain now continues to point to your main site, which is with another provider. The subdomain, however, points to the website with us.
A practical example: 
  • is your main domain. It is hosted by another provider. 
  • "" should be set up at Sitejet. 
  • Connect in the Domain Manager
  • Set the appropriate subdomain for "sitejetsubdomain" in the CMS 
  • Create a CNAME for "sitejetsubdomain" at the domain hoster which is located on your site at Sitejet
  • Enjoy your subdomain at Sitejet
 In certain cases, the SSL certificate will take a little longer here as well. If everything is set up correctly, the certificate will be issued within a few hours. If you need help with this setup, please contact the support with your website ID, a screenshot of your settings and your DNS settings. We will be happy to help you! 

When you set up your subdomain in Sitejet, there must always be the "home" page with the URL: / . As your DNS-settings are pointed to the subdomain rather than the /home site and the site is set to "no index" this page will not be available for website visitors, unless they know how to reach it directly.
