What are Wikipedia’s reliable source standards?

Wikipedia’s reliable source standards are unusually specific and they are the standard most COI Wikipedia work fails against. A reliable source is independent of the subject, meaning the author and publisher have no affiliation with what is being covered. It is secondary, meaning it analyzes or describes rather than restating primary information. It is published, meaning it has gone through an editorial or publication process. It is professionally edited, meaning it carries the editorial standards of an established outlet. And it has a reputation for fact-checking, meaning the outlet is known to verify claims before publishing them. Press releases, sponsored content, native advertising, the company’s own website, social media posts, and wire-service syndications of company announcements are not reliable sources for notability or for substantive article content.
