Overview
Microsoft Advertising (formerly Bing Ads) is the advertising platform for search campaigns on Bing, Yahoo, and Microsoft's partner networks. It serves as Microsoft's primary advertising revenue platform.
What This Script Does
The Universal Event Tracking (UET) tag fires on advertiser websites to record conversion events—purchases, form submissions, sign-ups—and build remarketing audiences. It sets cookies to identify users who visited the advertiser's site and match them to their Bing search or Microsoft display ad exposure. The tag collects page URLs, referral data, conversion values, and browser metadata. This data flows into the Microsoft Advertising dashboard for campaign reporting, bid optimization, and audience targeting.

Does Bing Ads require cookie consent?
Yes. Bing Ads' Universal Event Tracking tag performs conversion tracking and remarketing audience building, placing it firmly in the marketing category. Under GDPR, explicit opt-in consent is required before the UET tag fires. Under CCPA, data sharing with Microsoft's ad platform requires opt-out rights.
What cookies does Bing Ads set on my website?
The UET tag sets _uetsid and _uetvid cookies on the bat.bing.com domain. _uetsid is a session cookie; _uetvid persists for 13 months. They record page visits, conversion events, and referral data to match site visitors against Bing search and Microsoft Display ad exposures.
How does ConsentStack manage Bing Ads consent?
ConsentStack detects the UET tag script and classifies it as marketing. The tag is blocked by default until a visitor grants marketing consent. On consent grant, the tag fires normally. On denial or before consent, the script is suppressed, preventing any cookies from being set or data from reaching Microsoft Advertising.
