How do you typically determine if user is navigating from within your website?

I understand Gatsby is essentially using reach/router for routing etc. With this in mind, it makes sense that you might go about determining if a user is navigating from within your website by doing something like the following: use location.state that you set with the state property on the Link component to set, say, a fromWithin state to true on every time you navigate to home page from within your website, and then read the location prop in your home page - if fromWithin is true, then you've navigated from within website, if not, you haven't.

The one problem with this is that whenever you refresh your home page, from some reason reach/router's location is retained as long as you haven't physically navigated to a different website (reach might just be using the window's location? either way). Should I bother figuring out how to clear reach/the window's location.state on page refresh to get around this problem, or is there a more suitable way of accomplishing the problem asked in the subject header?
