When citing a webpage or online article, the APA in-text citation consists of the author’s last name and year of publication. For example: (Worland & Williams, 2015). Note that the author can also be an organization. For example: (American Psychological Association, 2019).
If you’re quoting you should also include a locator. Since web pages don’t have page numbers, you can use one of the following options:
Paragraph number: (Smith, 2018, para. 15).
Heading or section name: (CDC, 2020, Flu Season section)
Abbreviated heading: (CDC, 2020, “Key Facts” section)
