How to use 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 a CNAME 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 "www.your-website.com", 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" for example (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 "your-website.com", you could create the following different subdomains:

  • "services." -> "services.your-website.com"
  • "contact." -> "contact.your-website.com"
  • "info." -> "info.your-website.com"
  • "blog." -> "blog.your-website.com"

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, a CNAME 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 "blog" might look like this:

Name                         Typ TTL Host/Value
blog CNAME
3600 website.sitehub.io

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 blog.your-website.com.

Please make sure, that under URL you only have the sign "/" (slash) in the field. You have now set up the subdomain blog.your-website.com.

Note: An SSL certificate is automatically created for each subdomain. If the certificate is not active after 48 hours, please contact us via help@sitejet.io and tell us your website ID and the corresponding subdomain. Please check the DNS settings if you are using a third-party domain, otherwise we will not be able to assist with the certificate.


Multilanguage with Subdomains

When you decide to create a multilangual website, this will, of course, also affect your subdomains. The concept of the multilanguage will stay the same. Sitejet automatically changes the URL for all available languages of the currently accessed page e.g. www.sitejet.io/en/templates, as follows:

www.sitejet.io/de/templates
www.sitejet.io/en/templates

For subdomains e.g. blog.your-domain.com this will also apply as follows:

blog.your-domain.com/de/
blog.your-domain.com/en/

Subpages with Subdomains

When you set up a subdomain and like to create a subpage for that specific subdomain, Sitejet will make it possible to use one more domain level. For your website blog.your-domain.com the following structure will be possible: 

<blog.your-domain.com/subpage> 

The same applies to a multilingual website: 

<blog.your-domain.com/de/subpage> 
<blog.your-domain.com/en/subpage>

Set up only a subdomain at Sitejet

With Sitejet, it is possible to use your domain with another hoster and only use the subdomain with us. This way www.your-domain.com is pointing to your website somewhere else, but your subdomain like "blog." is pointing to Sitejet via blog.your-domain.com. 
  1. First, you need to set up the domain in the Domain Manager in Sitejet. If you do not yet know, how to do this, please follow the guide "Activate forwarding". (Please do not change the DNS settings for the domain at your third-party provider unless you want your website to point to Sitejet.)
  2. When the domain is connected in the Domain Manager, Sitejet is able to recognize the domain assigned to the website.
  3. Now set up your subdomain exactly as you want it in the website builder. Then, save the website.

  4. Afterwards, remove the "/" (Home site) with the www-subdomain from the pages section. 

  5. Once this is done, switch to your domain hoster. Here, you set the appropriate CNAME for your subdomain. Your domain now continues to point to your main site, which is with another provider. The subdomain, however, points to the website with us.
Name                         Typ TTL Wert/Host/Value
blog CNAME 3600 website.sitehub.io
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 help@sitejet.io with your website ID, a screenshot of your settings and your DNS settings. We will be happy to help you! 

Important Notice: When you only set up your subdomain in Sitejet, there should not be the "home" page with the URL: / anymore. You will only be able to remove that page after the subdomain is set up correctly.  If you do not remove it, the SSL-certification might not work.
