Help with PPC tracking, using UTM parameters

Hi all,

We are having quite the issue tracking PPC traffic. Marketo Support has explained that apparently UTM parameters are not tracking past the original landing page, and that custom code would be required if we want to track conversions on deeper pages.

I find it extremely hard to believe that there aren't customers who are tracking PPC with UTM parameters successfully, without custom code.

Has anyone had this same problem, or have any thoughts on how we might remedy it?

Note: we use hidden fields to capture the source, medium, and campaign parameters.

Thanks so much in advance!
