Consent Mode V2: stay compliant without losing your conversion data

Privacy rules are tightening, and Google now requires Consent Mode V2 to use audiences and conversion data in many regions. Get it wrong and you can lose remarketing, lose conversion modeling, and in some cases lose the ability to run certain features at all.

Consent Mode is the bridge between your cookie banner and your tracking. When a visitor makes a choice, Consent Mode tells Google and Meta what they are allowed to do. If consent is granted, tracking runs fully. If it is denied, tags adjust their behavior instead of firing as normal.

Version 2 adds two new signals for ad personalization and ad user data, on top of the existing analytics and ad storage signals. Google uses these to stay compliant and to model the conversions it is no longer allowed to observe directly.

Here is the part most businesses miss. Consent Mode done right does not have to gut your data. With conversion modeling, Google estimates the conversions from users who declined cookies, so you keep a usable picture of performance while respecting their choice. The setup has to be correct for this to work.

We implement Consent Mode V2 through Google Tag Manager, wired to a proper consent banner, with the right default and update states. We test that consent signals flow correctly before, during, and after a visitor makes a choice.

Compliance and measurement are not opposites. With Consent Mode V2 set up properly, you respect user privacy and keep the data you need to run your ads. Book a free audit if you are not sure your consent setup is doing both.
