Container
01 Definition
Container meaning: The unit in a tag management tool that holds all tags, triggers, and variables for a site.
In Google Tag Manager, a container groups the tags, triggers, and variables for one website or app. You install its snippet once, then manage everything inside through versions you publish. Each container has its own ID, and mixing containers across properties can create confusing or duplicated tracking.

Why it matters
How Container fits the work
The container gives you one controlled place to manage tracking, with versioning and publishing that make changes easier to review and roll back if something breaks.
In context
The team publishes a new container version that adds a scroll-tracking trigger, then rolls back to the previous version after spotting duplicate events.
Practical note
Keep container scope clear, usually one per web property. Running two containers on the same page, or reusing one across unrelated sites, often leads to double counting or missed events.
