Following the introduction of Google Consent Mode v2, Microsoft is now tightening the rules of the game. As of May 5, 2025, use of the Microsoft Advertising service requires implementation of the Microsoft UET Consent Mode, in line with new Microsoft guidelines. These rules apply to advertisers operating in the European Economic Area (EEA), the UK and Switzerland.

Microsoft UET Consent Mode is a mechanism introduced by Microsoft to enable its Universal Event Tracking (UET) advertising tags to respect users’ consent choices regarding cookies and tracking.

In concrete terms, it allows UET tags to:

  • Enable or disable data collection based on user consent
  • Maintain advertising performance within a framework that meets privacy expectations

This system follows the same logic as Google Consent Mode v2, ensuring that advertising platforms act in a transparent and compliant manner with regard to personal data.

Simplified integration thanks to biskoui

At biskoui, we know that ease of implementation is essential, especially for SMEs, agencies and web developers. That’s why we’ve integrated native support for Microsoft UET Consent Mode into our interface.

Microsoft UET Consent Mode can be activated in 2 clicks with biskoui — from our interface, add your Microsoft Advertising, activate the consent mode and that’s it. Your site is easily compliant.

1. Install Microsoft Advertising

  • Log in to the biskoui dashboard at admin.biskoui.ch
  • Go to the Services menu
  • Add Microsoft Advertising with the integration mode of your choice
  • Log in to the biskoui dashboard
  • Go to the Services menu

Activating Microsoft UET Consent Mode in the biskoui.ch platform

Note that Google Consent Mode v2 can also be activated from the Consent Modes tab.

Once Microsoft UET Consent Mode has been activated in biskoui, it’s essential to check that your UET tags react correctly to users’ consent choices. Microsoft has released an official Chrome extension: UET Tag Helper. This tool allows you to:

  • Detect the UET tags present on your site
  • Check in real time whether they are loaded correctly
  • Ensure that they comply with the consent transmitted by biskoui

Verification steps:

  1. Install the UET Tag Helper extension from the Chrome Web Store
  2. Activate it on your website
  3. Simulate different consent scenarios using the biskoui banner
  4. Check that the behavior of UET tags adjusts accordingly (delayed or limited loading in the absence of consent)

In a nutshell

With the introduction of Microsoft UET Consent Mode, Microsoft reinforces the importance of rigorous and transparent consent management in the advertising ecosystem. Thanks to biskoui, you can meet these new requirements in just a few clicks, without technical complexity, while guaranteeing optimum compliance in the EEA, the UK and Switzerland.
