What is Wikipedia's notability guidelines?
Each sources is evaluated based on three key factors: reliability, significant coverage, and independence from the subject.
Each source must satisfy all three factors for it to be used as a reference.
However, in certain cases, a source with a brief or trivial mention may be used for verification purposes, but it doesn't count towards the general notability of the subject of the article."
General Notability Guidelines of Wikipedia
A topic is presumed to be suitable for a stand-alone article or list when it has received significant coverage in reliable sources that are independent of the subject.
Reliability
Sources need editorial integrity to allow verifiable evaluation of notability, per the guidelines. Sources may encompass published works in all forms and media, and in any language. Availability of secondary sources covering the subject is used to test notability.
Coverage
The source addresses the subject directly and in detail, so that no original research is needed to extract the content. Significant coverage is more than a trivial mention, but it does not need to be the main topic of the source material.
Independent
It excludes works produced by the article's subject or someone affiliated with it. For example, advertising, press releases, autobiographies, blogs, most interviews, and the subject's website are not considered independent.
Trivial Mention
A single or insignificant mention of the subject in an article that may or may not be related to the subject.
Secondary Source
They provide an author's own thinking based on primary sources, generally at least one step removed from the event. It contains an author's analysis, evaluation, interpretation, or synthesis of the facts, evidence, concepts, and ideas taken from primary sources. Secondary sources are not necessarily independent sources.
