Include external page in conversion funnel
I have a problem with including an external landing page (instapage) into our conversion funnel:
This is the funnel users e.g. from CPC go through: cpc campaign>external landing page>internal booking page>internal confirmation page
What happens currently is that the traffic is counted double, once coming from the cpc campaign and once coming from the landing page (either indicated via source/medium (UTM link) or if i don't have this UTM link it goes into direct/organic traffic). The conversions are only attributed to either the UTM link or direct/organic traffic.
I tried to exclude this landing page as referral, but then I miss the traffic that goes to the landing page which doesn't convert to the next (internal) page.
The external landing page is hosted on our server. We could also add custom tracking code there.
Does anyone have a solution for this?
