Within Wikipedia, notability determines whether a topic merits its own article. Article topics are required to be notable, or "worthy of notice." Determining notability does not necessarily depend on things like fame, importance, or the popularity of a topic—although those may enhance the acceptability of a subject that meets the guidelines explained below.

A topic is presumed to be notable enough to merit an article if it meets the general notability guidelines below. A topic can also be considered notable if it meets the criteria outlined in one of the more subject specific guidelines listed on the right.

These notability guidelines only outline how suitable a topic is for its own article. They do not directly limit the content of articles. For Wikipedia's policies regarding content, see Neutral point of view, Verifiability, No original research, What Wikipedia is not, and Biographies of living persons.

General notability guideline

If a topic has received significant coverage in reliable sources that are independent of the subject, it is presumed to satisfy the inclusion criteria for a stand-alone article.

• "Significant coverage" means that sources address the subject directly in detail, and no original research is needed to extract the content. Significant coverage is more than a trivial mention but it need not be the main topic of the source material.
• "Reliable" means sources need editorial integrity to allow verifiable evaluation of notability, per the reliable source guideline. Sources may encompass published works in all forms and media. Availability of secondary sources covering the subject is a good test for notability.
• "Sources," for notability purposes, should be secondary sources, as those provide the most objective evidence of notability. The number and nature of reliable sources needed varies depending on the depth of coverage and quality of the sources. Multiple sources are generally expected.
• "Independent of the subject" excludes works produced by those affiliated with the subject including (but not limited to): self-publicity, advertising, self-published material by the subject, autobiographies, press releases, etc.
• "Presumed" means that significant coverage in reliable sources establishes a presumption, not a guarantee, that a subject is suitable for inclusion. Editors may reach a consensus that although a topic meets this criterion, it is not appropriate for a standalone article. For example, such an article may violate what Wikipedia is not.

A topic for which this criterion is deemed to have been met by consensus, is usually worthy of notice, and satisfies one of the criteria for a stand-alone article in the encyclopedia. Verifiable facts and content not supported by multiple independent sources may be appropriate for inclusion within another article.

Notability requires verifiable evidence

The common theme in the notability guidelines is that there must be verifiable objective evidence that the subject has received significant attention by the world at large, to support a claim of notability.

The evidence must show the topic has gained significant independent coverage or recognition, and that this was not a mere "flash in the pan", nor a result of promotional activity or indiscriminate publicity, nor is the topic unsuitable for any other reason. Sources of evidence include recognized peer reviewed publications, credible and authoritative books, reputable media sources, and other reliable sources generally.

Self promotion and indiscriminate publicity

Publication in a reliable source is not always good evidence of notability:

Wikipedia is not a promotional medium. Self-promotion, paid material, autobiography, and product placement are not valid routes to an encyclopedia article. The barometer of notability is whether people independent of the topic itself (or of its manufacturer, creator, author, inventor, or vendor) have actually considered the topic notable enough that they have written and published non-trivial works of their own that focus upon it – without incentive, promotion, or other influence by people connected to the topic matter.

Neutral sources are also needed to guarantee a neutral article can be written — self-published sources cannot be assumed neutral; see Wikipedia:Autobiography and Wikipedia:Conflict of interest for discussion of neutrality concerns of such sources. Even non-promotional self-published sources, like technical manuals that accompany a product, are still not evidence of notability as they do not measure the attention a subject has received by the world at large.

Notability is not temporary

Notability is not temporary: a topic needs to have had sufficient coverage in reliable sources to meet the general notability guideline, but it does not need to have ongoing coverage. However, Wikipedia is not a news source: it takes more than just a short burst of news reports about a single event or topic to constitute sufficient evidence of notability – particularly for living individuals known for one event (WP:BLP1E). For example, routine news coverage such as announcements, sports coverage, and tabloid journalism is not a sufficient basis for a topic to have its own standalone article. The Wikimedia project Wikinews covers topics of present news coverage. For guidelines on whether an event is notable, see Wikipedia: Notability (events).

Notability is also not predictable. A topic that does not meet the general notability guideline at one time may do so later. However, articles should not be written based on speculation that the topic may meet the criteria in the future.

Similarly an existing topic might be deleted if a later review of evidence suggests that the topic did not actually achieve notability. This can sometimes happen when notability was not discussed earlier in its history or was discussed but there was no clear consensus; when there was a flurry of media reports but it has since become clear the topic was not notable; after a significant cleanup (eg to remove improper or promotional material) when it is easier to judge notability; and in certain disputes where time allows a more dispassionate appraisal of enduring noteworthiness.

Notability guidelines do not directly limit article content

The notability guidelines determine whether a topic is notable enough to be a separate article in Wikipedia. They do not give guidance on the content of articles except in the case of stand-alone lists. Instead, various content policies govern article content, with the amount of coverage given to topics within articles decided by its appropriate weight.

Articles not satisfying the notability guidelines

Although articles should demonstrate the notability of their topics, and articles on topics that do not meet this criterion are generally deleted, it is important to consider not only whether notability is established by the article, but whether it readily could be. Remember that all Wikipedia articles are not a final draft, and an article can be notable if such sources exist even if they have not been added at present. Merely asserting that such sources exist is seldom persuasive, especially as time passes and actual proof does not surface. If it is likely that significant coverage in independent sources can be found for a topic, deletion due to lack of notability is inappropriate unless active effort has been made to find these sources. For articles of unclear notability, deletion should be a last resort.

If an article fails to cite sufficient sources to demonstrate the notability of its subject, look for sources yourself, or:

• Ask the article's creator or an expert on the subject for advice on where to look for sources.
• Put the {{notability}} tag on the article to alert other editors.
• If the article is about a specialized field, use the {{expert-subject}} tag with a specific WikiProject to attract editors knowledgeable about that field, who may have access to reliable sources not available online.

If appropriate sources cannot be found after a good-faith search for them, consider merging the article's content into a broader article providing context. Otherwise, if deleting:

• If the article meets our criteria for speedy deletion, one can use a criterion-specific deletion tag listed on that page.
• Use the {{prod}} tag, for articles which do not meet the criteria for speedy deletion, but are uncontroversial deletion candidates. This allows the article to be deleted after seven days if nobody objects. For more information, see Wikipedia:Proposed deletion.
• For cases where you are unsure about deletion or believe others might object, nominate the article for the articles for deletion process, where the merits will be debated and deliberated for seven days.
