we experience some session breaks during payment process user journey. In Adobe Analytics we register a lot of site entries on payment referrer, something we didn't expect, because payment process should not last that long to end the session.
I try to debug the payment process and try to understand what params tell Adobe the session number? In the tracking call sent to Adobe, how can I tell at what point the session is a new one?
If you have visits that start with your payment processor, that has nothing to do with the quality of your implementation (generally speaking, at least).
Adobe Analytics determines a session break by 30+ minutes between image requests. This means someone could be sitting on the checkout page, about to confirm a purchase, get distracted or forget about it for an hour, then make the purchase. The site could very well be open the entire time, but since Adobe Analytics determines sessions based on the timestamp of image requests, you'll always get new visits that are really the continuation of an long-stalled session.
I agree this can happen, but should always be the minority. The majority is expected to have a straight journey, otherwise something is poor.
But I tested it myself and found that the session doesn't break or end, it is rather wrongly attributed. Entries of direct traffic are strangely attributed to the first encounterd referrer.
So if I come directly to website and conduct a payment, in the reports my entry is marked as coming from this referrer instead of typed/bookmarked. Still have to find out why, though. I believe it has something to do that we always send the referrer variable, even if it is empty, then we just send an emtpy string "". Maybe this conflicts...
