I am a bit concerned about making a “unicorn” setting here cause of all of the chrome everywhere needed to surface it.
But I do like the idea a lot of using tags for this…
-
Add a site setting (or maybe longer term “tag setting”) for
excluded_from_web_indexing_tags -
Then if you want to keep this totally hidden, create a tag group and only make this tag visible to relevant groups.
This it will always be clear to the powers that be that you are looking at a topic that will not be indexed by Google/Bing/Etc.
