A page load or a route change is considered as a View. A View is a single visit to your web site/app by your user. If the user refreshes/revisit your page again, then it is considered as separate View. When there is a route change event in a single page app, it is also considered as a View.

Lets say user refreshes/revisit your page 5 times, then it is equivalent to 5 views or when a user clicks and changes to a different route within your single page app, then it is considered a separate View.
