How to track unidentified users in web and Mobile analytics

Question

We are using the web and mobile analytics for tracking data from the website into marketing cloud via IGO and PI data extension. We are able to track identified users that means when they logged into our website we can track them using below code

function sendUserInfo() {
_etmc.push(["setOrgId", "*******"]);
_etmc.push(["setUserInfo", { "email": uname }]);

}

But the challenging we are facing here is how to track the unregistered users who visited our site.

what we have tried till now:

We created a custom field in IGO_profiles called Cookie ID and we included this field in the setUserinfo function, but it is not tracking any info of cookieID(support confirmed that for now analytics DE's doesn't support custom fields)

can anyone shed some light on this how to capture unregistered or unidentified users

Note: I have gone through the documentation but it's of no use

Answer 1

Unidentified (anonymous) visitors are automatically assigned a cookie with an ID by IGO Collect scripts, on the domain: igodigital.com - this is the domain where the tracking scripts are served from.

You should look for the cookie named: igodigitaltc2, which contains the uuid assigned to your browser:

When you look in e.g. IGO_VIEWS of PI_CONTENTVIEWS Data Extensions, you will see same value show in the user_id column:

Hence linking the behaviour to a specific user across page views and sessions. Once you execute _etmc.push(["setUserInfo", { "email": uname }]); call, this user_id gets linked to your own identifier, passed in the place of uname in your example above. Only these users who are identified will be found in IGO_PROFILES Data Extension, allowing you link them to your own contact data (user_id is the cookie ID above, and email is your identifier sent to setUserInfo call):
