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 using duplicate arguments in template calls	duplicate-args-category	The page contains template calls that use duplicates of arguments, such as `{{foo\|bar=1\|bar=2}}` or `{{foo\|bar\|1=baz}}`.
Pages with too many expensive parser function calls	expensive-parserfunction-category	The page uses too many expensive parser functions (like `#ifexist`). See Manual:$wgExpensiveParserFunctionLimit.
Pages containing omitted template arguments	post-expand-template-argument-category	The page is bigger than `$wgMaxArticleSize` after expanding a template argument (something in triple braces, like `{{{Foo}}}`).
Pages where template include size is exceeded	post-expand-template-inclusion-category	The page size is bigger than `$wgMaxArticleSize` after expanding all the templates, so some templates were not expanded.
Hidden categories	hidden-category-category	The category contains `__HIDDENCAT__` in its page content, which prevents it from showing up in the category links box on pages by default.
Pages with broken file links	broken-file-category	The page contains a broken file link (a link to embed a file when the file does not exist).
Pages where node count is exceeded	node-count-exceeded-category	The page exceeds the maximum node count.
Pages where expansion depth is exceeded	expansion-depth-exceeded-category	The page exceeds the maximum expansion depth.
Pages with reference errors	cite-tracking-category-cite-error	Pages in this category have errors in the usage of references tags.
