Identify visitors

Visits and visitors

The tag gives each browser an anonymous device id and each visit a session id, stored in first-party cookies. A visit ends after 30 minutes without activity.

A visitor is one browser or device. The same person on two devices counts as two visitors, and Safari limits the cookie to seven days, so a Safari visitor who returns after a week counts again.

Identify a signed-in user

When someone signs in, tell the tag who they are:

window.pageTracker.identify({ user: 'user-42', org: 'acme' });

Before the tag has loaded, queue it instead:

window.pageTrackerQueue = window.pageTrackerQueue || [];
window.pageTrackerQueue.push(['identify', { user: 'user-42', org: 'acme' }]);

• user and org can each be up to 254 letters, digits and _ . @ + -. An email address is allowed.
• Call window.pageTracker.identify({}) when they sign out.
• The ids are never written to a cookie.

Other ways a user is recognised

• When a visitor signs in through a login form, the email address or username they typed is recorded as the user.
• When your site tells another analytics tool who the user is, and Kontala reads that tool, the user is recorded as well.

Where to see it

The Visits explore shows each visit's sign-in state: Signed in, Signed out, Signs in later or Anonymous. The Audience dashboard's Identified and Organisations tabs show identified visitors and their company domains.
