If Google correctly recognizing consent status of your visitors is failing, this can lead to incorrect data in Google Ads and Analytics. The correct transmission of consent signals is crucial for data quality. Furthermore, faulty recognition negatively affects conversion modeling. As a result, you lose valuable optimization opportunities.

Why Google Is Not Recognizing Your Visitors’ Consent Status

The problem often lies in a missing or faulty connection between CMP and GTM. When the consent signal is not sent in the correct format, Google does not recognize the consent status of visitors. Consequently, all users are treated as ‘not consented’. Additionally, a missing consent update after the user’s decision can be the cause. More details in our FAQ on Google Ads warning.

How to Ensure Correct Consent Recognition

First, you need to check whether the default consent is correctly set. Then you should verify in the Tag Assistant that the consent update is triggered after the user’s decision. Furthermore, the wait_for_update parameter is important so the GTM waits for the CMP signal. As a result, Google correctly recognizes the consent status. The Google Consent Mode documentation explains the details.

Our Recommendation

We recommend using Google Tag Assistant to verify consent signals in real time. First, check whether the default consent is correctly set to ‘denied’. Then, ensure that a consent update is sent after every user decision. Additionally, it is important to correctly configure all four v2 parameters.

Conclusion

In summary, correct consent recognition is the foundation for reliable tracking. Without it, neither modeling nor remarketing works properly. Contact us for a Consent Mode analysis.
