GTM
Google Tag Manager (GTM)
The tag management system: a single interface to add, edit and fire tracking scripts (GA4, pixels, conversions) without touching the site code each time. The logic of “what fires, when, and with what data” lives in a container, not scattered across pages.
“GTM” is part of Glossary · Tracking & data — part of the Atlas, Websem's reference of AI search, marketing and data terms.
