Mapping user journey in a single device across multiple browsers

I want to know how to map a user who uses multiple browsers in a single device. The person has never logged in. what to do in such a case.

 

do i need Customer journey analytics to map users (who are not logged in) but browse website using multiple browsers in the same device or without Customer journey analytics, I can map these users.

 

The problem statement is: how to identify and figure out the journey of a user who has visited my website using meta's in-app browser, then later on visited my website using google chrome. In this case, 2 ECIDs are generated. In both cases, user did not log-in. So how do i track this person's behavior. In both cases, the device used was same.

If a user uses different browsers and doesn’t log in, you can’t track them as the same person. Each browser creates a new ID. Even with Customer Journey Analytics, you need a common ID (like login or email) to link their journey.

Ok. So any reason why we cant use a device ID (GAID, IDFA) to map ECIDs?

 

So let's say a person, who does not log in (in both cases), using Device A from chrome browser & secondly use firefox browser (again device A, the same), why can't I map this user using Device ID & ECID?

 

Since the common identifier is device ID in both browsers in a single device.

Hi

 

again circling back to same question. For stiching without PII (email or phone), do I need CJA (customer journey analytics) or not?

 

Any reason if I dont want to stich user journey without using PII (email or phone), why do i still need Customer journey analytics (CJA)?


Hi @josh__stephens,

Would you be able to support @ankitsi6 further on this, or should we escalate it to our internal SMEs? Let me know what do you think.

Thanks!
