Tracking categories

This page lists tracking categories which are automatically populated by the MediaWiki software. Their names can be changed by altering the relevant system messages in the MediaWiki namespace.

Tracking category	Message name	Category inclusion criteria
Indexed pages	index-category	The page has a `__INDEX__` on it (and is in a namespace where that flag is allowed), and hence is indexed by robots where it normally wouldn't be.
Noindexed pages	noindex-category	The page is not indexed by robots because it has the magic word `__NOINDEX__` on it and is in a namespace where that flag is allowed.
Pages with too many expensive parser function calls	expensive-parserfunction-category	Too many expensive parser functions (like `#ifexist`) included on a page. See Manual:$wgExpensiveParserFunctionLimit.
Pages containing omitted template arguments	post-expand-template-argument-category	After expanding a template argument (something in triple braces, like `{{{Foo}}}`), the page is bigger than `$wgMaxArticleSize`.
Pages where template include size is exceeded	post-expand-template-inclusion-category	After expanding all the templates, the page size is bigger than `$wgMaxArticleSize`, so some templates weren't expanded.
Hidden categories	hidden-category-category	This is a category with `__HIDDENCAT__` on it, which prevents it from showing up in the category links box on pages, by default.
Pages with broken file links	broken-file-category	Category added if the page contains a broken file link (a link to embed a file when the file does not exist).
