How do the GTM metrics work on Fibr?

gtm metrics makes it simple for you to use existing metrics to track personalization performance on fibr tag duplication and how gtm metric tracking works this step is required for fibr to track the exact same metrics that you are already tracking with your analytics tool we do it in a way such that no customer data is received by fibr, even if you have configured it in your original tag in tag duplication, fibr creates a custom html tag on gtm, which informs fibr's system once a metric is fired in order to achieve the firing at the same time as your original tag, we create a trigger, which is a combination of your original trigger and a fibr script load trigger this compound trigger ensures that every time your original tag is fired, the fibr tag also fires, thus maintaining data sanity across your analytics and fibr analytics this way of setting up gtm ensures that fibr does not miss any user activity you are already tracking and that the customer data remains intact within your systems
