I was stupid enough to develop a new project on a subdomain of another domain while figuring out the domain name for the new project. Now, a few weeks into the new project on it's own domain I realise that the old domain's subdomain (my staging / dev. server if you will) is indexed in google.
I deleted the content of that subdomain a while ago, but this evening decided to re-create it (it's empty) in order to verify it in search console, because I expected it to be removable from there, but it doesn't seem to be the case; only the temporary removal tool. Should I just wait it out or should I use the temporary removal tool?
When reading ou on it there seems to be so many different approaches, all pointing in different directions.
Thanks in advance!
