Hi @Jim Gilliam ,
In case all that happens inside the Confluence instance is working as an internal knowledge base, with everything being logged in, Google Search Engine will never even try to crawl and index it.
It only works in case you have the “Anonymous Access” option turned on.
In that case, your pages may be crawled and indexed by search engines, but with this configuration option, you control whether they follow external links on those pages.
So in your case:
Your content is already protected by authentication
Your content is not indexed by search engines at all
This option will not make a difference
You may ignore it unless you are planning to expose any of your pages
