SiteTraceKit Glossary
What is Google Tag Manager?
Google Tag Manager is a tag-management system that can load analytics, marketing and other scripts through a container.
Short definition
A GTM container is a public script reference, often visible as googletagmanager.com/gtm.js with a container ID.
Simple example
A page might include https://www.googletagmanager.com/gtm.js?id=GTM-XXXXXXX.
Why it matters for website checks
A visible GTM signal tells teams that marketing or measurement logic may be managed outside the main website codebase.
Limits
A GTM marker does not reveal the full container configuration and does not prove which tags fire for every user or region.
What does this mean for website owners?
Use the signal as a starting point for manual review. The website’s purpose, technical environment and actual configuration provide the necessary context.

FAQ
Does a GTM signal mean analytics is active?
Not necessarily. It means the container marker is visible. The container setup needs separate review.
Can SiteTraceKit inspect the GTM container?
No. SiteTraceKit reads public page signals and does not execute the container.
Why is GTM relevant for website owners?
It often centralizes marketing scripts, so owners should know who controls the container and what it loads.
