Just finished reading +Daniel Waisberg
's new book about Google Analytics Integrations. I was confident that I would pick up some tips and tricks and wasn't disappointed!
A couple of things in chapter 11 - Email Data Integration - were not quite clear to me.
First, there is a method about tracking email opens. In the example, the mailchimp uniqid
is used for the cid
. Do I understand correctly that you are just using this approach for the sake of getting a cid? In other words, you are not trying to actually identify the same visitor who may have signed up on your website and then opened an email from mailchimp. You "just" care about aggregate data for an email campaign.
The second confusing aspect for me is that in the same chapter 11 the mailchimp uniqid is then used for setting the GA userId
not the cid
. Should you really do that?
