Google Consent Mode
& Privacy-Compliant Tracking

Privacy regulations are not slowing down. GDPR, CCPA and a growing list of state and regional laws mean how you collect data matters as much as what you collect. But Google Consent Mode done wrong is not only legal exposure. It breaks conversion tracking, corrupts your Google Analytics 4 data, and quietly hands Google a modelled guess in place of the campaigns that actually produced revenue. Done properly it costs far less data than most setups give away, and what remains is something you can scale on.

Overview

What this includes

Consent management platform setup

We configure your CMP to communicate consent signals correctly to GTM and your ad platforms. Whether you're using Cookiebot, OneTrust, Complianz, or another solution, we make sure the integration is doing what it's supposed to and that consent categories are mapped to the right tag firing conditions.

Consent Mode v2 implementation

Google's Consent Mode v2 is now required for advertisers who want to use audience features and conversion modeling in Google Ads. We implement the full v2 signal set including ad_storage, analytics_storage, ad_user_data, and ad_personalization so your campaigns stay eligible for modeling and your data gaps are filled where consent is denied.

Conversion modeling and data recovery

When users decline consent, Google's modeling uses behavioral patterns to estimate what conversions would have occurred. We make sure your setup is correctly configured to take advantage of modeling so your reported conversion numbers reflect a complete picture rather than only the users who accepted all cookies.

Validation across consent states

We test tag behavior in both the granted and denied states, confirm signals fire in the correct sequence, and document the whole setup so you can show exactly how your tracking responds to a user's choice.

Our process

How we implement consent mode

Talk it through
  1. 01

    Discover your needs

    We start by understanding your current consent setup, which privacy regulations apply to your audience, and how your existing tags are behaving relative to user consent. We look at your CMP, your GTM container, and whether your consent signals are actually reaching your ad platforms and analytics.

  2. 02

    Audit your tag firing against consent

    We review every tag in your GTM container to confirm tags are only firing when the appropriate consent has been granted. Tags firing before consent or ignoring consent signals entirely create both a compliance gap and a data quality problem.

  3. 03

    Configure your consent management platform

    We set up or fix your CMP integration so consent signals are communicating correctly to GTM and your ad platforms. Whether you are using Cookiebot, OneTrust, Complianz, or another solution, we make sure consent categories are mapped to the right tag firing conditions.

  4. 04

    Implement Consent Mode v2

    We implement the full v2 signal set including ad_storage, analytics_storage, ad_user_data, and ad_personalization so your campaigns stay eligible for conversion modeling and your data gaps are filled where consent is denied.

  5. 05

    Validate and hand off

    We confirm consent signals are firing in the correct sequence, test tag behavior across both consent granted and consent denied states, and document the full setup so your team understands what is in place and why.

Common questions

Why is my conversion tracking dropping off after I added a cookie banner?

Because your consent mode is not implemented correctly. When a cookie banner appears without proper consent mode configuration, tags that depend on user consent stop firing entirely for users who decline. This means you lose conversion signals, your GA4 data drops, and your ad platforms stop receiving the information they need to optimize. Consent mode done right fills those gaps through modeling so you stay compliant without gutting your data quality.

How do I know if my consent mode setup is actually working?

If your GA4 session counts dropped significantly after you added a cookie banner, if your conversion numbers are lower than expected for users in GDPR or CCPA regions, or if your Google Ads account is showing warnings about consent mode, your setup has problems. A working consent mode implementation should maintain data continuity through modeling even when users decline cookies.

What does consent mode and privacy-compliant tracking setup include?

A complete setup covers auditing your current tag firing behavior against your consent signals, configuring your CMP to communicate correctly with GTM and your ad platforms, implementing the full Consent Mode v2 signal set, validating tag behavior across both consent granted and consent denied states, and confirming your campaigns are eligible for conversion modeling in Google Ads.

Can Vizionality set up consent mode if I already have a cookie banner installed?

Yes. Most businesses have a cookie banner without proper consent mode integration behind it. We audit what is in place, fix the CMP to GTM connection, implement the correct v2 signals, and validate the full setup. Having a banner and having a correctly integrated consent mode are two different things and most setups we review only have the first one.

How is consent mode implementation different from a standard GTM audit?

A GTM audit reviews your container for firing errors, duplicate tags, and structural problems. Consent mode implementation specifically addresses how your tags respond to user consent signals and whether your setup keeps you compliant while preserving as much data quality as possible through modeling. Many clients discover consent mode gaps during a GTM audit, which is why we often handle both together.
