A website is a collection of webpages that are under one domain. One website will have several webpages like Home, About Us, Contact Us, Services, Products, etc. All of these pages together make up a website. In other words, a webpage is an independent page of a website.
If you simply mention a whole website it is not necessary to create a reference list entry. Name the website in the text of your paper and provide the URL in parentheses.
