Best way to ask a question about how users got to the webpage?

This would be in the form on a short online survey where users will see it pop up some time after they land on the page.

I want to know the exact traffic source from which a user lands on a specific webpage, so that I can see where traffic comes from.

Some ideas I had were:

"How did you arrive on this website?" (i.e. clicking on a advertisement, clicking on an email, searching for it specifically etc...)

"Through which source did you find this website?" (i.e. same as above...)

EDIT: Thanks y'all for the Google Analytics suggestions. Unfortunately what we're trying to do won't allow us to link Analytics to account data :( otherwise I definitely would just look at those data!

Thanks!
