What Is Wikipedia Notability and How Is It Assessed?
Wikipedia notability is the threshold editors use to decide whether a subject warrants a stand-alone article. It is not a ranking of moral value, commercial success, fame, or social importance.
The central question is whether reliable independent published sources have covered the subject in significant depth.
This guide shows how to assess that evidence systematically and distinguish notability from mere verifiability.
Quick answer: A subject is generally presumed suitable for a stand-alone Wikipedia article when it has received significant coverage in reliable sources independent of the subject, or when it satisfies an applicable subject-specific guideline. This creates a presumption, not a guarantee. Popularity, awards, search results, and many brief mentions do not replace strong sourcing.
What Wikipedia notability means
Notability answers one practical question: should this subject have its own article? It does not decide whether the subject may be mentioned anywhere on Wikipedia.
A topic that does not support a stand-alone page may still belong in a broader article, list, section, merger, or redirect. The outcome is not limited to either keeping or deleting a page.
Notability is | Notability is not |
A test for a stand-alone article | A judgment of moral worth or real-world importance |
An assessment based mainly on independent published coverage | A reward for success, size, fame, age, or popularity |
A presumption that an encyclopedic article can be written | A guarantee of publication or permanent retention |
A characteristic demonstrated by sources about the subject | A characteristic of a company's website, press release, or draft |
Separate from article quality and content policy | A substitute for neutrality, verifiability, or no original research |
The general notability guideline
English Wikipedia presumes a topic suitable for a stand-alone article when it has received significant coverage in reliable sources that are independent of the subject.
Multiple sources are generally expected.
The word presumed matters.
Passing the general test creates a reasonable assumption, but editors can still conclude that a separate page is inappropriate under other policies or because the topic is better covered elsewhere.
Significant coverage
A source should address the subject directly and in enough detail to provide meaningful material for an article.
A passing mention, list entry, routine announcement, or single quotation is normally insufficient.
The subject does not have to occupy the entire publication. The relevant portion must still contain substantial coverage that can be summarized without original research.
Reliable sources
Reliable sources have editorial integrity, accountable publication practices, and an appropriate reputation for accuracy in the relevant field.
Reliability depends on the specific source and claim, not merely the publisher's brand.
Independence from the subject
Independent sources are not produced, commissioned, or controlled by the subject or its affiliates.
Advertising, press releases, autobiographies, official websites, and sponsored profiles do not establish independent notability.
Secondary and published sources
Secondary sources analyze, interpret, or contextualize information rather than simply record first-hand claims. They may be online, printed, audiovisual, paywalled, or written in any language.
Part of the test | Question to ask | Typical failure |
Depth | Does the source discuss the subject directly and substantially? | A brief mention, list, event calendar, or isolated quote. |
Reliability | Does the publisher exercise meaningful editorial responsibility? | Anonymous blogging, self-published profiles, or uncontrolled content. |
Independence | Was the work produced without the subject's control or payment? | Press releases, company websites, paid features, or affiliated authors. |
Secondary analysis | Does the source add independent analysis or context? | Primary records, databases, filings, or interviews without analysis. |
Why there is no magic number of sources
Wikipedia does not prescribe a fixed universal source count because sources differ in quality and depth. Two weak pieces do not become persuasive evidence simply because there are two of them.
Several articles may also derive from one press release, wire story, book, or interview.
Publications without original intellectual contribution are usually treated as one underlying source for notability purposes.
one exceptional in-depth source may be valuable but is often insufficient alone;
two strong independent sources are a useful starting point, not automatic approval;
complex or controversial subjects may require a broader record for due weight;
subject-specific guidelines may provide additional or alternative criteria;
other content and inclusion policies still apply.
How to assess one source
Do not label a source simply usable or unusable. Record what it can establish, whether it contributes to notability, and which claims it can support inside an article.
Source type | Notability value | What it may support |
Independent profile or substantial book chapter | High | History, impact, development, context, and multiple viewpoints. |
Analytical or investigative reporting | High | Major events, criticism, consequences, and broader significance. |
Professional review or scholarly discussion | Moderate to high | The significance of a work, product, performance, or idea. |
Interview with the subject | Limited | Attributed statements, opinions, and some first-hand facts. |
Official website or annual report | Low for notability | Routine facts, names, dates, and the subject's stated position. |
Press release or sponsored feature | None or minimal | The subject's messaging, not independent significance. |
Directory, registry, or database | None | Existence and basic recorded facts. |
A practical source test
The following scoring model is a CTRL M diagnostic tool, not an official Wikipedia rule. Assign zero to two points in each area.
Depth: zero for a mention, one for several substantive paragraphs, two for extensive direct coverage.
Independence: zero for owned or paid content, one for partial influence, two for complete editorial independence.
Reliability: zero for uncontrolled publishing, one for a usable specialist source, two for an established editorial source.
Secondary analysis: zero for a primary record, one for a mixed format, two for original analysis and context.
Result | Working interpretation | Next step |
7–8 points | Strong candidate for demonstrating notability | Treat it as a core source and map the exact claims it supports. |
4–6 points | Supporting or borderline source | Use cautiously and continue searching for stronger independent coverage. |
0–3 points | Unlikely to establish notability | It may verify a detail, but should not be counted as core evidence. |
A high score for one source does not replace the need for multiple independent sources or the community's overall judgment.

Notability varies by subject
The general notability guideline is the default, but many fields have subject-specific guidelines. These may identify achievements or forms of coverage that usually indicate notability.
Subject type | Core question | Common mistake |
Company or organization | Is the organization itself covered substantially and independently? | Assuming revenue, scale, or famous customers automatically qualify it. |
Person | Is the person covered, rather than only their employer or work? | Treating follower counts or professional titles as sufficient. |
Product or service | Has the product received sustained independent analysis? | Inheriting notability from its manufacturer. |
Event | Is there enduring coverage, wider impact, and historical context? | Treating a short news spike as permanent significance. |
Website or online service | Is there independent and historically meaningful coverage? | Relying on traffic figures or search ranking. |
Creative work or music | Are there independent reviews, analysis, or specific criteria? | Assuming publication or distribution alone creates notability. |
Notability is not verifiability
Verifiability asks whether a particular statement can be supported by an appropriate source. Notability asks whether the available coverage collectively justifies a stand-alone article.
A government registry may reliably verify a company's incorporation date while contributing nothing to corporate notability.
An official biography may verify a birth date without showing why the person warrants a separate article.
Notability is not inherited
A subject does not become notable merely through association with another notable subject.
A famous founder does not automatically qualify a company, and a notable company does not automatically qualify every executive, product, or subsidiary. During research, isolate the portion of each source that actually covers the proposed article subject.
A profile of an investor containing one sentence about a startup is mainly a source about the investor.
Fame, search results, and social media
Followers, website traffic, search volume, viral reach, and raw numbers of Google results are not stand-alone notability tests.
They cannot distinguish independent editorial work from repetition, promotion, or simple text matches.
Search engines help locate evidence; they do not vote on who deserves a page. Evaluate the quality of the results, not their quantity.
When a case is borderline
A borderline case has sources that satisfy only part of the test. They may be reliable but brief, detailed but sponsored, or independent yet derived from the same original report.
two sources devote only a few sentences to the subject;
most coverage appeared during one short-lived news event;
the most detailed item is an interview or paid profile;
the sources primarily discuss a founder, product, employer, or event;
several publications repeat the same underlying announcement;
strong sources exist but cannot support a balanced article.
The safer response is to continue researching, prepare a draft outside mainspace, and seek transparent community review rather than forcing a premature article.
How the community assesses notability
Wikipedia has no central approval board. Assessment happens through editing, review, maintenance tags, talk-page discussion, draft review, and sometimes a deletion discussion. The strongest arguments identify specific independent sources and explain their depth.
Personal beliefs about importance, customer numbers, and the existence of other weak articles usually carry little weight.
Czech and English Wikipedia
Czech Wikipedia expresses its general test as sufficient coverage in reliable independent sources and commonly uses the practical concept of multiple independent, non-trivial, reliable sources. English Wikipedia more explicitly discusses secondary sources, the presumption created by significant coverage, and numerous subject-specific guidelines.
A result on one language edition does not automatically transfer to another.
What to do before drafting
Define the exact subject of the proposed article.
Collect all plausible independent published sources, including print and paywalled material.
Remove duplicates, republished press releases, sponsored content, and derivative pieces.
Assess each source for depth, reliability, independence, and secondary analysis.
Check whether a subject-specific notability guideline applies.
Build an outline only from information supported by the strongest surviving sources.
If the evidence is insufficient, pause rather than converting promotional material into a draft.

Frequently asked questions
How many sources are required to establish notability?
There is no fixed universal number. Multiple strong independent sources are generally expected. Their quality, depth, independence, and relationship to one another matter more than raw citation count.
Is one article in a famous publication enough?
Not automatically. A major outlet may publish a brief mention, sponsored feature, contributed post, or republished press release. The specific item and how it was produced must be evaluated.
Is notability the same as fame?
No. Fame may generate independent coverage, but followers, search volume, customers, and general popularity do not by themselves establish Wikipedia notability.
Can an official website establish notability?
An official website may verify limited routine facts, but it is not independent of the subject. It normally cannot demonstrate that a stand-alone article is warranted.
Can a company inherit notability from its founder?
No. Each subject must qualify through its own sources or an applicable subject-specific guideline. The same principle applies to products, subsidiaries, relatives, and employees.
Can a notable subject's article still be deleted?
Yes. Passing a notability guideline creates a presumption, not an absolute guarantee. Other policies, article scope, promotional purpose, or a persuasive community discussion may still affect the outcome.
Can PR coverage create Wikipedia notability?
Paid or subject-controlled publications are not independent. Manufacturing sponsored coverage therefore does not normally solve a lack of genuine notability.
Does an English assessment apply to Czech Wikipedia?
Not automatically. Each language edition has its own community, local guidance, and procedures. The evidence and workflow must be assessed again.

Summary
Wikipedia notability is not an award or marketing advantage. It is an evidence-based test of whether independent published sources provide enough substantial material for a neutral stand-alone article.
