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.
Any best practice advice on this? In the offical guidelines they hint that filing a removal request is the way to go if the content no longer exists.
Thanks in advance!
