What are the pros and cons of a subdomain?

A subdomain is a component of a domain that is subordinate to the domain name, it is also called a second-level domain. Consequently, a subdomain can also be referred to as a third-level domain. It precedes the domain name and is separated by a period. The following graphic shows the subdomain’s placement in the example.org URL.

Using a subdomain has several advantages. Firstly, you can create as many new subdomains as you want without incurring any extra cost or paying for a new web address. You can also market several products or offers on the same root domain, strengthening your brand.

It is worth noting that every subdomain is marked as its own website in the Google Search Console. It usually also requires much more effort when it comes to linkbuilding. Subdomains also generally don’t offer any advantage over a standard domain when it comes to Search Engine Optimization.

Note

Relying on WordPress on subdomains, along with subdirectories, is one of the URL structures you can choose when setting up WordPress multisite.

The exact procedure for creating and installing a subdomain on WordPress and others depends on which provider you host your project with. Many providers allow such configurations via the web-based tool cPanel. IONOS customers can create any subdomains as follows:

How to install WordPress on a subdomain, step by step

Installing WordPress on a subdomain is basically the same process as creating a new WordPress site. 1-click installation allows you to save a huge amount of time and effort. You can also choose a manual installation option if you want.

In the following steps, we outline each step with examples of both variations for IONOS customers.

Manually installing WordPress on a subdomain

Manually installing WordPress on a subdomain gives you control over which version you have on your online storage. It’s generally advised that you choose the most up-to-date version, but you can also opt for an older version this way.

Step 1: Download WordPress

Firstly, you download your chosen version of WordPress. Go to the official WordPress download page and click on the “Download WordPress x.x.x” button to get the latest version. You will find older versions under the “Releases” page.

Extract the downloaded ZIP file and save it to your local drive. In later steps, you will then need to transfer these program files into the WordPress subdomain online storage.

Step 2: Create a subdomain and add a DNS entry

If you have not already done so, create the desired subdomain as described above. However, once you have created a subaddress, you still need to create a new DNS entry for it. You can do this in the IONOS Cloud Panel using the following steps:

  1. Log in using the IONOS Login page.
  2. Click on the “Domains & SSL” button.
  3. Choose the domain for which you have created a subdomain on WordPress.
  4. Click on the “DNS” tab.
  5. Click on “Add a DNS record” and choose type “A”.
  6. Add the relevant information. Type in the address of your new subdomain under “Host Name”.
  7. Then save your work.
Tip

Should your subdomain contain an alias? Simply create the appropriate CNAME record directly in the panel.

Step 3: Create a database

You need a new database to install WordPress on a subdomain. IONOS users can also easily create these in the Cloud Panel. After logging into the customer area, take the following steps:

  1. Switch to the “WP Business” section.
  2. Click the “Manage” button in the “Databases” entry.
  3. Click on “Create database”.
  4. Choose your desired database type (Standard: MySQL).
  5. Insert a description and password.
  6. Click “Save”.
Note

Please note down the following data: database name, hostname, username and password. They will be required to include the created database into the WordPress installation on the subdomain.

Step 4: Upload WordPress files onto online storage

The next step is to install your chosen FTP client and connect it to the online storage your subdomain is being hosted on.

Tipp

You can read how to download the popular FileZilla FTP client and how to connect it to your chosen online storage in the FileZilla tutorial.

Look for the ./public.html/subdomain directory and upload the unzipped WordPress program files to this folder.

If you can’t find the directory, it is possible that the subdomain isn’t connected to the online storage. If so, take the following steps on IONOS Cloud Panel:

  1. Go to the “Domains & SSL” section.
  2. Choose the domain your subdomain runs under.
  3. Click the “Subdomains” tab and then click on the “use domain” button.
  4. Choose the “Connect to webspace” option and confirm this change by clicking “Save”.

Step 5: Edit wp-config.php

You will find a file named wp-config-sample.php in your uploaded files. Rename the file wp-config.php and open it in any text editor. Finally, add the data from the third step into the corresponding spots:

  • DB_NAME: Database name
  • DB_USER: Username
  • DB_PASSWORD: Password
  • DB_HOST: Hostname

Step 6: Install WordPress on a subdomain

Once you have added the database information to the configuration files and saved them, you can finally begin to install WordPress on the subdomain. Paste the following URL into your browser:

subdomain.domain.tld/wp-admin/install.php

Replace the preexisting subdomain.domain.tld with the address of your subdomain. As soon as you load the URL, the WordPress installation wizard will automatically start.
