Analytics & Tag Management
321,354 of the 1,000,000 top sites in our Tranco top-1M census run Google Tag Manager (32.1%). Google's tag-management container — usually the delivery mechanism for other trackers, not a tracker itself. Detection is homepage-level HTML/header fingerprinting, so a site can run Google Tag Manager on other pages without it showing here.
