I doubt I'm the only one that wishes Zendesk had two user segments for the unauthenticated end-user that we could apply to individual articles.

One for Everyone including Search Engines
New one for Everyone excluding Search Engines.

There are times we wish to have articles accessible without logging in, but not showing up in Zendesk sitemap and search index crawlers via "noindex" meta tags against individual article IDs. Being able to exclude articles from the sitemap would be a HUGE WIN!

Example would be a direct link URL of an announcement that wouldn't be hidden behind Log in, but also not showing up in search results across all/most search engines without having to manually remove the URL from Google's webmaster tools, since there are more search engines than just Google out there.
