Google Tag Manager
Udio has Google Tag Manager.
You can go to Settings - Customer Account Settings.
At the bottom of this page you cn enter 'Google Tag Manager ID' and 'Online bookings analystics Snippet'.
Those will allow you or your online marketing people to track customers going from your website to customer accounts and to the final step of online enrolment.
Google Tag Manager ID will be used on all pages, and allows companies that enter it to track the whole funnel and see where customers fall off.
Online Bookings Snippet is used on the very last step of the booking process, so it can track that people actually booked in.
For further information you need to contact your Website developers, however, we know that those two pieces are enough to track all the campaigns across all websites.
