professional website

A third party internet site published by a person or organization with professional knowledge of the data.

A professional website is an internet site where the content can be deemed reasonably trustworthy because it is provided by professionals with a working knowledge of the topic. The reliability of this source type falls between that of an official and a user-generated website, as professional sources may have a reputation to uphold but also may lack direct access to high-level data sources.

Examples of professional websites include the internet pages of governments, institutions, realtors, professional organizations, publishers, and news organizations.
