Question: Can we use the same profile merge rule to target in Non-Auth website too? Assume, we need to target the new user directly coming to non-auth website(www.example2.com). I believe, we can target the content in non-Auth website using same profile merge rule if the same user previously visited/loggedin in Auth-based website(www.example2.com).
Last Authenticated Profile:
Tells Audience Manager to read data from the authenticated profile of the user who last logged in on the device.
When selected, Audience Manager will not write new trait data to the authenticated profile if the user is anonymous. Upon authentication, new trait data gets written to the user's authenticated profile.
So effectively this is using the data profile of the last authentication and an anonymous user can be targeted based on that profile, even though navigating in non-authenticated mode.
