WP engine tutorial: If you use WP Engine as your web hosting then this video will guide you on creating a Subdomain to your domain. With Subdomain, you can create a completely new website and/or new pages which can be used to track any marketing campaigns you are carrying on. Or you can also duplicate your whole site and play around with the site.

While creating a subdomain is very easy on the WP engine, but, depending on your packages you might have some restrictions on accessing the site. We created a subdomain demo on our parent site, but after installing WordPress it had some password restrictions and we had to upgrade it to use it. If the subdomain purpose is only for learning or experimenting then it would not be an issue.
