I have recently started buying google ad for some promotion.
Ultimately I want to drive signup by these ads.
In acquisition, I can find this set of figures of my campaign.
There is this 'Goal 1: create an account'.
My questions are
1) I don't know how I can register a successful user signup as 'Goal 1' in google analytics.
2) There are 12 session for this campaign. But when I switched to AUDIENCE-> User Explorer with the same campaign as criteria, there is only one user. How does these 12 sessions mapped to the one user?
