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 pagesโ (empty) | 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 pagesโ (22 C) | 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 callsโ (empty) | 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 callsโ (1 P) | expensive-parserfunction-category | The page uses too many expensive parser functions (like #ifexist). See Manual:$wgExpensiveParserFunctionLimit. | 
| Pages containing omitted template argumentsโ (empty) | 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 exceededโ (empty) | post-expand-template-inclusion-category | The page size is bigger than $wgMaxArticleSize after expanding all the templates, so some templates were not expanded. | 
| Hidden categoriesโ (538 C) | 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. |
