This page in a nutshell: Add template messages to inform readers and editors of specific problems with articles or sections. Do not use them as a badge of shame.
The following template messages may be added to articles needing a cleanup. Their purposes are to foster improvement of the encyclopedia and to notify readers about possible problems.
Unless otherwise noted, the cleanup messages, or tags, should be placed at the top—before other templates, images, or infoboxes, but after a possible hatnote (see WP:Hatnote#Placement). Certain tags can be placed at the top of an individual section, and others can be placed within the text itself (inline). Where the problem is not obvious, add an explanatory remark via the reason parameter as shown below or via the talk page.
Don’t insert tags that are similar or redundant. For example, all articles that read like essays have an inappropriate tone, and in fact they end up being automatically grouped in the same category, so it is unnecessary to tag with both {{Inappropriate tone}} and {{Essay-like}}. Similarly, if an article has many problems, tag only the most important, a lengthy list often being less helpful than a shorter one. A tag is not intended as a badge of shame. (See also: tag bombing.)
A date parameter is added by a bot, or you can provide a date yourself.
Does the article meet inclusion requirements?
Before placing templates on a page it is worthwhile to cast a critical eye over the page to determine whether it should, in fact, be included in Wikipedia. Some articles can be tagged for speedy deletion or marked as an article for deletion.
Best practices in obscure or unpopular articles
On pages that have received little attention from editors or readers, cleanup templates can be used as a way to call attention to problems that need to be addressed by editors. Editors who want to help address these problems should look through the various cleanup categories such as maintenance and articles with content issues and try to address the problems so that the templates can be removed. Editors who do a lot of tagging of articles should also address the backlogs.
Best practices in heavily monitored articles
On pages that are being edited by a number of users, cleanup templates are used to inform readers and editors of ongoing discussions and attempts to fix the problems on the page. Such templates can be used to attract uninvolved users to discussions and cleanup efforts, and they can also serve as a warning to casual readers that the article may have problems and be subject to dramatic changes. In general, an editor who places a template message to indicate a problem like this should explain their rationale fully on the talkpage of the article. If the consensus of the other editors is that there is a problem or an editorial dispute that deserves such a clean-up template, then the editors should work to fix the problem as quickly and cleanly as possible so the template message can be removed. If the consensus is that there is no problem, then the message can be removed immediately. For heavily monitored articles, please do not add or remove template messages of this sort without using the talk page.
Use in sections
Many of these cleanup tags require you to place |article as the first parameter when you use the tag at the top of an article. When you want the template to refer to just one section, however, you replace |article with |section (where the | is a pipe key found on most keyboards as a shift-backslash (\). See the specific template below to determine if such "section use" is supported and appropriate.
Tag consolidation
If too many tags are put at the top of an article, the article can become eclipsed by the tags, especially with short or stub articles. Consider consolidating the tags into the {{Multiple issues}} template.

For use when a nonfiction article has become overcrowded with too many references to fiction or other pop culture. (Ex.: Article on horses having a long section of TV shows, movies, video games, etc. that have "horse" in the name or feature horses in some way.)
For use in fiction-specific articles that have way too many trivial examples. (Ex.: For an article specifically about famous fictional horses that mentions the fact that Sesame Street once told kids how to spell "horse", or that one of the animals you can kill in an online game is a horse.)
To identify a list on Wikipedia that has content whose truth, factual nature, and/or relevance to the topic is in dispute. There is also an inline version, {{List fact}}.
