This is a maintenance category, used for maintenance of the Wikipedia project. It is not part of the encyclopedia and contains non-article pages, or groups articles by status rather than subject. Do not include this category in content categories.
This category tracks pages that have had the __NOINDEX__ behaviour switch added to them, so that they do not show up in web search engines such as Google. This category is added automatically by the MediaWiki software. The category name is defined in MediaWiki:Noindex-category (see Commons:MediaWiki:Noindex-category for a switch based on namespace).
