I have launched a subdomain website for admin purposes. Simply for staff and clients to login and view private pages. I've ticked to discourage search engines to index it as I don't want it to be found.

However, I am concerned that discouraging search engines on the subdomain may impact the way they crawl the main public domain. Therefore, should I set it up on a completely different domain or is it fine to leave things as they are?

  • What makes you think that a subdomain being private will affect the primary domain?

  • I just want to make sure that it won't impact it negatively? Basically just worried in case it does.

  • When you say "ticked to discourage search engines" does that mean that it is powered by WordPress? The "Discourage Search Engine" option in WordPress creates a robots.txt file that disallows all crawling. Or are you using some other platform or using some other mechanism like password protecting the whole thing? Aug 13, 2021 at 10:06
  • Yes its a basic wordpress website on the subdomain and I have ticked to discourage search engines. The pages on it are all password protected - just with the basic password option for viewing wordpress pages.

Google treats subdomains as separate domains. Your admin subdomain will not affect the organic visibility of your main site.

Unless the content is sensitive/confidential, don't worry!

If it is confidential, I would recommend something like Cloudflare - when we “discourage” (disallow in robots.txt, no follow) Google respects this.

Other bots, especially malicious ones, have no obligation to honor this request. They will not respect it.
