I am trying to track the next action from an entry page with a query string.
Scenario: prospect visits page with a query string and value ?utm_campaign=sample. If they click from here to a next page and fills out a form, I am trying to capture that they came from that previous page.
I set up a Fills out Form trigger, form name is any, referrer contains "sample". But it is not working.
My guess is that Referrer does not consider query string text. Is there a way around this without writing code into the cookie?
