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 |
|---|---|---|
| Pages with broken file links (31 P) | broken-file-category | The page contains a broken file link (a link to embed a file when the file does not exist). |
| Pages using duplicate arguments in template calls (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 where expansion depth is exceeded (empty) | expansion-depth-exceeded-category | The page exceeds the maximum expansion depth. |
| Pages with too many expensive parser function calls (empty) | expensive-parserfunction-category | The page uses too many expensive parser functions (like #ifexist). See Manual:$wgExpensiveParserFunctionLimit. |
| Hidden categories (empty) | 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. |
| Indexed pages (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. |
| Pages where node count is exceeded (empty) | node-count-exceeded-category | The page exceeds the maximum node count. |
| Noindexed pages (empty) | 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 non-numeric formatnum arguments (empty) | nonnumeric-formatnum | The page contains a non-numeric argument to the formatnum parser function. |
| Pages containing omitted template arguments (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 exceeded (empty) | post-expand-template-inclusion-category | The page size is bigger than $wgMaxArticleSize after expanding all the templates, so some templates were not expanded. |
| Pages with ignored display titles (2 P) | restricted-displaytitle-ignored | The page has an ignored {{DISPLAYTITLE}} because it is not equivalent to the page's actual title. |
| Pages which use = as a template (empty) | template-equals-category | The page contains {{=}} but on this wiki that does not expand to =. This usage is deprecated; a future MediaWiki version will implement {{=}} as a parser function. |
| Pages with template loops (empty) | template-loop-category | The page contains a template loop, ie. a template which calls itself recursively. |
| Pages with script errors (2 P) | scribunto-common-error-category | There was an error when processing the modules included on the page. |
| Scribunto modules with errors (empty) | scribunto-module-with-errors-category | The module has an error in it. |

| Files with no machine-readable description (empty) | commonsmetadata-trackingcategory-no-description | The file does not have a machine-readable information template, or its description field is not filled out. |
