How to remove an entire subdomain from the Google index with URL removal tool?

[nicole.healthline]

Does anyone have clear instructions for how to do this? Do we need to set up a separate GWT account for each subdomain? I've tried using the URL removal tool, but it will only allow me to remove URLs indexed under my domain (i.e. domain.com not subdomain.domain.com)

Any help would be much appreciated!!!

Entering the subdomain into the box without any slashes will indicate that you are trying to remove the site - and after submitting it, it will indicate the request as a "Site Removal"

Example:

Enter the URL that you'd like to remove (case-sensitive)

Enter:

testing.website.com

Hi Michelle,

You need to verify the subdomain itself as its own site in Google webmaster Tools, then you can request removal of that entire site (subdomain).
