In this video, you’ll learn how to create and use the Constant variable in Tag Manager. We’ll explain how it stores a fixed value, such as an ID, key, or static text, that stays the same across all tags and triggers. You’ll see how to create this variable, name it, and add it to tag setups to save time and keep configurations consistent. The video also shows how it behaves in debug mode, holding the same value across events. By the end, you’ll know how to use Constant variables to simplify your setup and reduce repetitive work.
