Microsoft UET Tag Guide: Conversion Tracking & Variable Revenue (2026)

UET = Universal Event Tracking. It is the Microsoft equivalent of the Facebook Pixel + Google Tag. If you import goals from Google Analytics (GA4), they work... mostly. But Native UET is better. It tracks view-through conversions and allows for richer audience building.

In this "Mega-Authority" guide, we cover:

1. Creating the Tag.
2. GTM Installation.
3. Variable Revenue: Tracking dynamic Purchase values.
4. UET Tag Helper: Debugging.

Part 1: Creating the Tag

1. Tools -> UET Tag.
2. Create UET Tag. Name it "Main Website".
3. Copy the Tag ID (e.g., 12345678).

• Note: You only need 1 tag for the whole website.

Part 2: GTM Installation (Base Code)

1. Open Google Tag Manager.
2. New Tag -> Microsoft Advertising Universal Event Tracking.
3. Paste UET Tag ID.
4. Trigger: All Pages.

Part 3: Dynamic Revenue (Purchase Event)

Unlike Google, Microsoft uses "Goals" based on UET events.

1. GTM Tag: New Tag -> Microsoft UET.
2. Track Type: Custom Conversion.
3. Goal Value: Equals to -> {{transactionTotal}} (Your GTM Variable).
4. Goal Currency: USD.
5. Trigger: Purchase Event.

Crucial: In Microsoft UI, go to Conversion Goals -> Create Goal -> Website -> Event using UET Tag. Match the parameters you sent from GTM.

Part 4: The Shared Library

Because you installed UET, you can now create Remarketing Lists.

• "All Visitors": Built automatically.
• "Cart Abandoners": Create list where "URL contains /cart" AND "URL does not contain /thank-you".
• Strategy: Bid +50% on "Cart Abandoners" in your Search Campaigns.

Part 5: Summary & Checklist

Your Action Plan:

1. Create UET Tag.
2. Install via GTM template.
3. Install "UET Tag Helper" (Chrome Extension).
4. Verify the tag is firing on all pages.
5. Test a purchase to ensure Revenue Value is passed correctly.

Measure everything.
