Frequently Asked Questions

A Google feature that adjusts GA4 (and Google Ads) tag behaviour based on user consent, and uses modelling to fill in data gaps for non-consenting users.
The updated version (launched 2024) requiring two new parameters (ad_user_data and ad_personalization) in addition to the original analytics_storage and ad_storage.
For businesses running Google Ads targeting EEA users, Consent Mode v2 was required from March 2024 to maintain Smart Bidding and remarketing performance.
Basic mode blocks GA4 tags entirely until consent is given. Advanced mode fires tags before consent but in a cookieless state, allowing modelling for non-consenting users.
GA4 uses machine learning to estimate behaviour and conversions for users who declined consent, filling gaps so your reports aren't heavily underreported.
No — you still need a Consent Management Platform (CMP) to collect and manage user consent. Consent Mode translates those signals for Google's tags.
Google-certified CMPs include Cookiebot, OneTrust, Usercentrics, TrustArc, and others. We integrate with whichever CMP you use.
Using GTM Preview to check consent state parameters in the dataLayer before and after consent, and checking GA4's Consent Overview report.
Without Consent Mode, users who decline cookies are completely missing from your data. With Advanced Consent Mode v2, modelling fills those gaps, typically recovering a significant portion of reported conversions.
We can implement Consent Mode v2 manually via GTM with a custom consent signal setup.
