So, here's a GIF on how to create a CNAME record on GoDaddy:
Step 1: You can log in to your GoDaddy Domain Control Center.
Step 2: Select your domain to access the Domain Settings page.
Step 3: Under Additional Settings, select Manage DNS.
Step 4: Select Add under the records table.
Step 5: Under Type, select CNAME.
Step 6: Enter the details for your CNAME record:
Host: The hostname, or prefix, the CNAME record will be set to.
You can include a period (.) but not as the first or last character. Consecutive periods (...) are not allowed, and the host cannot exceed 25 characters or be the @ symbol.
You can't use a host already assigned to an existing A, TXT, or MX record.
Points to: The URL you are setting as the destination for the host. Type @ to point directly to your root domain name.
TTL: Determine how long the server should cache information.
The most common CNAME host is www, with the @ symbol entered for the Points to field. This will make www.coolexample.com load to the same webpage as the root domain, coolexample.com.
Step 7: Select Save to save your new CNAME.
Please allow up to 48 hours for your changes to propagate globally.
