Q. How do I cite a website where there is no author listed or date the article was written? APA style

For more details, see our APA Guide linked at the end of this answer.

Are you citing the entire website or a specific (set of) page(s)?

For entire websites, long story short, the APA website says:

• When citing an entire website, it is sufficient to give the address of the site in just the text.
  • Example: Kidspsych is a wonderful interactive website for children (http://www.kidspsych.org).

  • Do not include it on the References page

For specific pages, cite as the type of webpage it is - periodical or non-periodical

• Article From an Online Periodical
  • Online articles follow the same guidelines for printed articles. Include all information the online host makes available, including an issue number in parentheses.
  • Format: Author, A. A., & Author, B. B. (Date of publication). Title of article. Title of Online Periodical, volume number(issue number if available). Retrieved from http://www.someaddress.com/full/url/
