I have a issue with trying to devise a funnel in Google Analytics.
I am not looking to create a goal funnel, as I am looking to do it retroactively on my data so I need to either do the crunching manually or devise a strategy for it.
I wish to see sessions who have navigated from these pages, for example:
/ -> Category page A -> Cart -> Conversion / -> Category page B -> Cart -> Conversion / -> Category page C -> Cart -> Conversion
How would I go about creating a funnel like this in Google Analytics and extract this data retroactively (emphasis so I do not get recommendations for setting up goal funnels since I want to do this on already processed data)?
I imagine I could use the segmentation sequence, but how reliable is that? I am getting sampled data very quickly and I want to be able to do this for a couple of months back, but I get sampled even after choosing a week. Any ideas?
