This article provides an overview of how GTM compares with Tealium and describes the GTM-to-Tealium migration process.
In this article:
GTM has six components:
A GTM Workspace allows you to create multiple sets of changes (versions) for your container. This is approximately the same as Environments.
GTM Templates are similar to the Tealium Custom Container. You can build a custom tag that’s not natively supported by GTM or implement a distributed custom template via the gallery view.
Triggers are similar to load rules, the jQuery onHandler extension and view/link calls.
Variables are approximately the same as data layer variables.
The Folder concept is similar to Tealium Labels
A GTM user has just launched a new site and wants to add Google Analytics to all pages, and track an event when someone clicks the hero banner on the homepage.
