Microsoft Ads (UET) and cookie consent on Shopify
Microsoft Ads (UET) (Microsoft) is one of the most common trackers on Shopify. Here’s what it does, the data it collects, and how to check whether it fires before your visitors consent.
What is Microsoft Ads (UET)?
Microsoft Ads’ UET (Universal Event Tracking) tag measures conversions from Bing/Microsoft campaigns and enables retargeting.
What data does Microsoft Ads (UET) collect?
Browsing and purchase events, with identifiers (`_uetsid`, `_uetvid`).
Why it needs consent
Microsoft Ads (UET) is a marketing/advertising tracker. In Europe, a non-essential tracker like this must only fire AFTER the visitor consents. If it loads or sets its cookie before, the very purpose of cookie banners isn’t being respected.
How it shows up
We detect Microsoft Ads (UET) via these network/cookie signals:
Does Microsoft Ads (UET) fire on YOUR store?
Our free scanner loads your storefront in a clean browser, without touching the cookie banner, and tells you in ~30 seconds which trackers fire before consent — and which app loads them.

The fix is to actually block the tracker until the visitor consents (via your tag manager, theme, or a properly configured banner). We’re building the Shopify compliance assistant that pinpoints the responsible app and blocks trackers before consent — automatically.
