The operator of the links has to do this. Not the person sharing the link. It's the job of the companies to make sure their pages don't get publicly indexed. It's basic web dev stuff that has worked like that for decades now.

"The operator of the links"? Not the person sharing the link? The pages of the companies?

What do you think I just explained?

Yes, Google Docs (and Sheets and Drive and Photos) can share via Google users (secure, granular) or "Public Link". The reason that you don't see results for these services in Google Search is because Google de-indexes them automatically if they are found by their crawler!

Everyone else crawling the web and social media? They can also find Public Links shared by Google users, or MS 365 users, or Dropbox or whatever.

And it's a feature, not a bug. Public links are public. When Claude or Gemini or Grok provide you a public link, it's public. The URL is like a "password" in that its UUID will work for anyone who clicks on it. That's simply the nature of public links.

If you wanna share securely then you get an Enterprise-class service, or you tell your LLM to generate a Word doc file, you stash it in your secure cloud storage, and you grant access to other authenticated users, and you don't ever create a public link.
