Microsoft UET
September 24, 2025
Microsoft UET (Universal Event Tracking) is Microsoft's conversion tracking tag for Microsoft Advertising. It tracks user actions, measures campaign effectiveness, and enables remarketing campaigns. By default, c15t loads this script based on marketing consent.
Info
UET can also load Microsoft Clarity (if enabled in your UET tag settings). Since Clarity is an analytics tool, we recommend loading it separately with measurement consent instead.
