The content itself has been the subject of multiple non-trivial published works whose source is independent of the site itself.
This criterion includes reliable published works in all forms, such as newspaper and magazine articles, books, television documentaries, websites, and published reports by consumer watchdog organizations.
The website or content has won a well-known and independent award from either a publication or organization. The content is distributed via a medium which is both respected and independent of the creators, either through an online newspaper or magazine, an online publisher, or an online broadcaster.

Sites that violate the copyrights of others per contributors' rights and obligations should not be linked. Linking to websites that display copyrighted works is acceptable as long as the website has licensed the work. Knowingly directing others to a site that violates copyright may be considered contributory infringement. If you know that an external Web site is carrying a work in violation of the creator's copyright, do not link to that copy of the work. Linking to a page that illegally distributes someone else's work sheds a bad light on Wikipedia and its editors.

For albums, movies, books, and other creative works, links to professional reviews.
