GDPR & Consent

Consent Mode Implementation

Google Consent Mode v2 setup with CMP integration, correct default and update states, and behavioural modelling activation. Works with any CMP.

Implementation GDPR Compliance

Google Consent Mode v2 configured in your tag manager, with CMP integration and verification that behavioural modelling is actually active.

Best for

Any business using Google tags in the EEA that has not yet implemented Consent Mode v2, or has Basic mode in place where Advanced would recover more data.

  • 6-8 hours, works with any CMP
  • All four consent parameters configured
  • Regional defaults set for EEA and non-EEA
  • Advanced mode enables behavioural modelling in GA4

Overview

How to know if you need Consent Mode Implementation

  • You use Google Ads or GA4 in the EEA and have not implemented Consent Mode v2.
  • You have Consent Mode technically in place but have not confirmed whether it is Basic or Advanced mode, or whether behavioural modelling is active.
  • Your CMP fires its consent callback but you have not verified it fires before Google tags initialise rather than after.
  • You are using Basic mode and want to switch to Advanced mode to recover conversion data through behavioural modelling.
  • You are not confident your regional defaults are correctly configured for EEA versus non-EEA audiences.

What Consent Mode Implementation covers

  • All four consent parameters configured: ad_storage, analytics_storage, ad_user_data, and ad_personalization.
  • Default and update commands placed in the correct firing order in your tag manager.
  • CMP callback wired so user choices propagate to Google tags before they initialise, not on the next page load.
  • EEA and non-EEA regional defaults configured to match your data collection strategy.
  • Advanced mode enabled where appropriate, with behavioural modelling activation verified in GA4.

Consent Mode Implementation outcomes

  • Google tags that respond correctly to user consent choices, confirmed via four-state network testing.
  • Behavioural modelling active in GA4 and Google Ads, recovering attribution from non-consenting users.
  • Test results per consent state and configuration documentation delivered at handover.

Consent Mode Implementation scope and hours

  • 6-8 hours.
  • Works with Cookiebot, OneTrust, CookieYes, Complianz, Didomi, Usercentrics, or any CMP that exposes a consent callback.
  • GTM container access is required for implementation.
  • Scope confirmed after reviewing your current CMP and tag manager setup.

What makes our Consent Mode Implementation different

  • We verify behavioural modelling is actually active in your GA4 account after implementation, not just that the configuration looks correct.
  • Consent signal timing is tested via network interception, not assumed based on the GTM setup.
  • The distinction between Basic and Advanced mode matters and we configure Advanced where it applies, not just the minimum required.
  • Works with any CMP. We do not require you to switch platform to work with us.

Our approach

How we deliver Consent Mode Implementation.

A structured process built around your stack, your team, and your data.

01

CMP and tag audit

We review your existing CMP configuration and identify every Google tag that requires consent signals before firing.

02

Consent mode architecture

Default and update commands are configured in the correct order within your tag manager, with Advanced mode enabled where appropriate.

03

CMP integration

Your CMP's consent callback is wired to the tag manager so user choices propagate to Google tags immediately, not on the next page load.

04

Regional defaults

EEA and non-EEA defaults are set to match your data collection strategy, with no overcollection in restricted regions.

05

Four-state testing and modelling verification

Tag behaviour is verified across all consent states via network interception, and behavioural modelling activation is confirmed in your GA4 account.

Frequently Asked Questions

What is the difference between Basic and Advanced Consent Mode?
Basic mode prevents Google tags from firing until consent is given. Advanced mode allows Google tags to observe cookieless behaviour even when consent is denied, which activates behavioural modelling and recovers some attribution data.
Which CMPs do you support?
Any CMP that exposes a consent callback: Cookiebot, OneTrust, CookieYes, Complianz, Didomi, Usercentrics, and others. If your CMP exposes consent events, we can wire them to Consent Mode.
What are regional defaults?
Regional defaults define how Google tags behave before a user interacts with the consent banner, per region. EEA defaults should typically deny consent until explicit user action. Non-EEA defaults can be set more permissively depending on your data strategy.
Does Consent Mode replace a cookie banner?
No. Consent Mode is the technical layer that communicates consent decisions to Google tags. You still need a compliant cookie banner to collect those decisions from users.
What is behavioural modelling?
When Advanced mode is active, GA4 and Google Ads use statistical modelling to estimate conversions and behaviour from users who declined cookies, based on patterns from users who consented. This partially recovers the data loss from consent-denied users.

Pairs well with

01

GDPR Tracking Compliance Audit

Technical audit of how your tracking stack responds to user consent choices. We intercept network requests across all consent states and document exactly which tags fire before they should, which consent signals are missing or misconfigured, and whether Consent Mode v2 is correctly integrated with your CMP.

02

Improve Cookie Consent Acceptance Rate

Track and improve your cookie consent acceptance rate. We instrument banner interactions to establish a baseline, then help you design and run tests around copy, positioning, and design to improve the rate without compromising compliance.

03

Usercentrics Banner Implementation

Full Usercentrics deployment: banner configuration, GTM or direct integration, Consent Mode v2 wiring, and four-state validation. Covers both the UI layer and the underlying consent signal flow.
