I'm in charge of a website that puts people in touch with financial experts according to your need.
You explain what kind of questions you have, specify some criteria and the algorithm proposes you 3 experts. At this point, you can either choose one directly and you're taken to the next step, where you choose a time for him to call you. Or you can first read the profile of one of the experts and go to the next step from there, where again you choose a time for him to call you.
So I created a different goal for each possible path. The destination is the same but the funnel is different, depending on whether the user checks the expert's profile before he says when he'd like to be contacted by him or not.
The problem is that Google Analytics seems to be double counting conversions: every time a user reaches the destination page (or perhaps only when he takes a certain path, I'm not sure), the counter for both goals is increased by one, even though presumably only one of the path was followed.
