We are planning a migration from http to https and I want to understand what happens, if anything, to UTM parameters on the original http link. If someone clicks on a non-secure version of our URL with our tracking UTMs in place… will the redirect to our HTTPS version of the URL cause the UTM parameters on the original HTTP link to “fall off”.
Your UTM parameters wont break if someone tries to access http as opposed to https. Our marketo pages are secure (https) and I just tried to load a UTM link pointing to http. Page was just re-directed to https and the UTM parameters were maintained.
Hope this helps!
