Some background info:
I've set up a page rule in CloudFlare at a certain URL (on the same domain), let's say /track-referral
This page rule instantly redirects visitors to our website's homepage. What I'd like to be able to do is track exactly what number (and preferably proportion) of visitors land on the homepage having visited the redirect URL first.
I can think of ways to manually do this by reading the HTTP referer header (I'm assuming it's managed by CloudFlare) but I'm already using both Google Analytics and Hotjar. I'd imagine GA is going to be the way forward but nothing's intuitive there, I've looked around a bit and not managed to find anything matching my objective that works.
