APA Citation Style: Internet resources

According to apastyle.apa.org:

• Provide as specific a date as is available on the webpage. This might be a year only; a year and month; or a year, month, and day.
• Italicize the title of a webpage.When the author of the webpage and the publisher of the website are the same, omit the publisher name to avoid repetition (as in the World Health Organization example).
• When contents of a page are meant to be updated over time but are not archived, include a retrieval date in the reference.
• Use the webpage on a website format for articles from news websites such as CNN and HuffPost (these sites do not have associated daily or weekly newspapers). Use the newspaper article category for articles from newspaper websites such as The New York Times or The Washington Post.
• Create a reference to an open educational resources (OER) page only when the materials are available for download directly (i.e., the materials are on the page and/or can be downloaded as PDFs or other files). If you are directed to another website, create a reference to the specific webpage on that website where the materials can be retrieved. Use this format for material in any OER repository, such as OER Commons, OASIS, or MERLOT.
• Do not create a reference or in-text citation for a whole website. To mention a website in general, and not any particular information on that site, provide the name of the website in the text and include the URL in parentheses. For example, you might mention that you used a website to create a survey.

Basic format:

:Author, A. (date). Title of Webpage or document [format description]. Retrieved from http://URL
That format description in brackets is used only when the format is something out of the ordinary, such as a blog post, twitt, or lecture notes; otherwise, it's not necessary.

For archival or recoverable documents, use the following format (from Publication Manual of the American Psychological Association --7.10) :

According to the American Psychology Association website https://www.apastyle.org

• Use the name of the account that uploaded the video as the author.

Author, A. A. (year, month day). Title of video  [Video]. YouTube. Retrieved from http://xxxxxxxxx

• If the account did not actually create the work, explain this in the text if it is important for readers to know. However, if that would mean citing a source that appears unauthoritative, you might also look for the author’s YouTube channel, official website, or other social media to see whether the same video is available elsewhere. -- apastyle.apa.org
