How to stop indexing on Web Template Editor

Hi Guys, Sorry its my first post so please move if in the wrong location! I've noticed recently that some cPanel accounts on my VPS that are suspended or haven't added files comes up with the default template (which is okay). However I've noticed that these are getting indexed by Google or even giving me a backlink which I don't want happening. Is it possible to add something to the Web Template Editor files to stop this from happening? I've added the following: to the pages but is there anything else I can do? I also noticed this code If you are the owner of this website, please contact your hosting provider: [% data.name FILTER html %] Is it possible to make it not hyperlink to my domain name but instead keep my name as my clients will already know how to contact me. Thank you in advance, Conor
