Microsoft Ads UET tag setup and consent

Universal Event Tracking (UET) is how Microsoft Advertising measures conversions and builds remarketing audiences. A missing or misfiring UET tag means smart bidding in Microsoft Ads optimizes on partial data, even when Google Ads looks healthy.

Consent matters here too. Microsoft Advertising expects consent signals for visitors from regions with consent requirements, such as the EEA, the UK and Switzerland. Markitech reviews the UET tag, its triggers and its consent settings in your Tag Manager container together, and proposes fixes you approve.

How to do it

1. Create or find the UET tag in Microsoft Advertising.
2. Add it to Google Tag Manager on all pages, with consent handling for regions that require it.
3. Create conversion goals for the events that matter, using event or destination URL goals.
4. Pass revenue and currency on purchase goals.
5. Publish the Tag Manager change after review and check goal status in Microsoft Advertising.

Common mistakes

• Copying Google Ads conversions into Microsoft Ads without a working UET tag behind them.
• Firing UET before consent where consent is required.
• Using destination URL goals on pages users can reach without converting.
• Leaving revenue off purchase goals, which blocks ROAS-based bidding.
