A byline is a piece of information providing the author's name, publication date, and sometimes, editors or their biographical information. It usually sits between the headline and the body text or below the story. You can often encounter bylines in newspapers and magazines.

A byline can be easily confused with the term "metadata" which refers to information about a document. It could contain the author's name, the creation date, as well as file size and keywords used to describe the document. In contrast to bylines, this information is invisible, embedded into the HTML page, and helps search engines understand the content and context of your website.^[1]

The byline is considered secondary text and should be smaller than the body text. Make sure to distinguish the byline from the content by using bold or italics judiciously.
