What are Wikipedia’s notability guidelines?

Notability is the threshold a subject has to clear before Wikipedia will host an article about it. The technical definition is significant coverage in multiple reliable, independent secondary sources, and each of those words carries weight in practice. Significant means substantive treatment of the subject, not a passing mention or a quote inside an unrelated piece. Reliable means established outlets with editorial standards, not blog posts, press releases, or wire-service syndications of company announcements. Independent means written by people who are not affiliated with the subject, which rules out interviews where the subject is the only source. Secondary means analytical or descriptive coverage rather than primary documents like SEC filings. People need similar coverage of their professional or public activities. Without that record, an article either gets declined at submission or gets nominated for deletion later.
