www.googletagmanager.com in a checkout page script inventory
www.googletagmanager.com appeared on 94 of the 187 United States store cart pages we read on 30 August 2026, which is 50% of them, and on 14 it was loaded by a script or iframe tag, meaning it executed in the page.
What it is
Google Tag Manager container host. Loads whatever tags the container is configured to load, which can change without a site deploy.
We fetched googletagmanager.com on 30 August 2026 and it returned no page description. That is common for hosts that only ever serve assets, and it is also the situation the inventory requirement exists for: the host is on the page and nobody can say whose it is.
What to write in the justification column
List every tag the container publishes, not just the container. The container is the reason the inventory drifts.
This is a starting sentence, not an assessment. Requirement 6.4.3 wants your reason, written by someone at your company who can defend it.
