Client ID whithout login or even enter in a website
Hi, to all with advanced Google Analytics implementation knowledge. I would like to measure unique user ID and have all the path (since impressions and clicks from dcm campaign and navigation/conversion in a site) at unique user level. There is not log in, it is something always anonymous and even sometimes we use the banner offsite to send the user to a third not own domain sites where we have the dcm floodlights. There is a way to give an ID to an anonymous user and knows the path between campaigns (dcm) and navigation (Google Analytics Premium) or event third party sites where we have the DCM floodlight?
Thanks & Best regards
