We have our main site, www.tutoringprof.com, and we are creating a new site and we would like it to be www.becomeapharmacist.tutoringprof.com (so a subdomain). (we own both domains) Our question is, how do we connect that domain to the new site, in a way that it doesn't overwrite our main site. The reason we are doing this is that we are trying to segment our messaging and avoid hitting the 400 page limit cap on the main site. What are the steps to do this? The end goal is that when a user types in becomeapharmacist.tutoringprof.com, that it takes them to that URL and retains that URL slug. Currently its returning back to becomeapharmacist.squarespace.com.
