Q. How do I reference the same website but a different page?

If you have different pages from the same website they will have different URLs as well as different titles.  If there is no personal author then the Website owner will become the Corporate Author.  There will be separate citations for each page. The reference list will then include the individual webpages listed separately. 

Here is an example:

• Australian College of Nurse Practitioners. (2019). About nurse practitioners. Retrieved                                            from https://www.acnp.org.au/aboutnursepractitioners
• Australian College of Nurse Practitioners. (2019). Conference program.  https://www.acnp.org.au/conference-program
• Australian College of Nurse Practitioners. (2019). FAQs. Retrieved from https://www.acnp.org.au/faq-s

This Library Guide explains the difference between web pages and web documents for APA.
