# Google Consent Mode v2 Advanced Setup – Secure Privacy & GTM > Set up Google Consent Mode v2 Advanced Mode with Secure Privacy and Google Tag Manager. Step-by-step guide covering GCM v2 consent types, default states, and GDPR best practices. - Canonical: https://support.secureprivacy.ai/article/implementing-google-consent-mode-with-secure-privacy - Product: Consent Management - Category: Integrations - Published: 2025-10-05T13:00:00+00:00 - Updated: 2026-03-24T18:09:44.561+00:00 - Reading time: 4 minutes --- Google Consent Mode (GCM) is an API that adjusts how Google tags behave based on a user's consent choices. When integrated with Secure Privacy, it ensures your Google Analytics, Google Ads, and other Google tags automatically respect consent preferences — without manually blocking and unblocking each tag. As of March 2024, Google requires Google Consent Mode v2 for all websites using Google advertising products in the EEA. This guide covers the **Advanced Mode** implementation of Google Consent Mode v2 using the Secure Privacy CMP community template in Google Tag Manager (GTM). ## Basic vs. Advanced Mode: Which Should You Use?

Google Consent Mode: Basic vs. Advanced

Feature

Basic Mode

Advanced Mode

Tag behavior before consent

Tags do not fire

Tags fire with limited, cookieless data

Analytics data

Only from consenting users

Aggregate modeling for all users

Implementation complexity

Lower

Moderate

Data completeness

Partial

More complete (with modeling)

**Advanced Mode is recommended for most websites** because it provides better data coverage while still respecting user privacy. When a user declines analytics cookies, Google only collects aggregate, cookieless pings — no personal data is stored or transmitted. ## Who Is This Guide For? - Website administrators managing Google tags and consent flows - Developers and technical marketers implementing GCM v2 - Compliance professionals ensuring GDPR, ePrivacy, and EU User Consent Policy alignment ## How to Implement Google Consent Mode v2 (Advanced) with Secure Privacy ### Step 1: Prepare Google Tag Manager If you are an **existing Secure Privacy user** who previously added the consent script directly to your site's `` tag, remove it before proceeding. The GTM template handles script injection automatically. **New users** do not need to add any script to the site header — the GTM template manages it entirely. ### Step 2: Add the Secure Privacy CMP Template in GTM 1. In Google Tag Manager, go to **Tags** > click **New** 2. Click **Tag Configuration** 3. Select **Discover more tag types in the Community Template Gallery** 4. Search for **Secure Privacy** 5. Select the **Secure Privacy CMP** template 6. Click **Add to Workspace**, then confirm by clicking **Add** ### Step 3: Configure the Secure Privacy Tag 1. Enter your **Secure Privacy Domain ID** (found in your Secure Privacy dashboard under the **Installation** tab) 2. Configure any additional settings as needed for your consent banner ### Step 4: Set Default Consent States Default consent states in Google Consent Mode v2 determine tag behavior _before_ a user interacts with the consent banner. 1. Click **Add Setting** in the tag configuration 2. For each consent category, choose **Granted** or **Denied** from the dropdown 3. Set the **Region** using ISO 3166-2 codes (e.g., `DE` for Germany, `FR` for France). Use `all` to apply globally without geo-targeting 4. Click **Add** to save the setting > **GDPR best practice:** For EEA visitors, set all non-essential consent categories to **Denied** by default. For other regions, consult your legal team about appropriate default consent states. ### Step 5: Set the Consent Initialization Trigger Select **Consent Initialization - All Pages** as the trigger for the Secure Privacy tag. This ensures GCM v2 consent signals are sent before any other tags fire. ### Step 6: Save, Test, and Publish 1. Click **Save** 2. Use GTM's **Preview** mode to test the integration 3. Verify consent signals are being sent correctly using the GTM debug panel 4. Once confirmed, click **Submit** and **Publish** ## Google Consent Mode v2 Consent Types Explained GCM v2 supports five consent types plus two new parameters introduced to meet EU User Consent Policy requirements:

Secure Privacy automatically maps its consent categories to all seven Google Consent Mode v2 types, ensuring full compliance without manual mapping. ## Troubleshooting Google Consent Mode v2 in GTM ### Tag Not Firing as Expected Double-check that the trigger is set to **Consent Initialization - All Pages** and that no other consent management platform (CMP) scripts are installed on the page, as conflicts can prevent GCM signals from sending. ### Consent Changes Not Reflected in Google Tags Verify your **Secure Privacy Domain ID** is correct. Clear all caches and test again in an incognito window to rule out cached consent states. ### Advanced Mode Data Not Appearing in Google Analytics Consent Mode modeling requires a minimum traffic threshold. Google needs approximately **1,000 daily events** with consent granted for at least **7 consecutive days** before behavioral modeling activates in GA4. ## Frequently Asked Questions **Is Google Consent Mode v2 required for GDPR compliance?** GCM v2 itself is not a GDPR requirement, but it is required by Google to use audience features and remarketing with Google Ads in the EEA. A proper CMP like Secure Privacy remains necessary for actual GDPR consent collection. **What is the difference between Basic and Advanced Google Consent Mode?** In Basic Mode, Google tags do not fire until consent is granted. In Advanced Mode, tags fire immediately with cookieless, aggregate pings, then update when the user makes a consent choice. Advanced Mode provides more complete data through Google's modeling. **Does Secure Privacy support GCM v2 automatically?** Yes. The Secure Privacy CMP GTM template maps all consent categories to the seven GCM v2 consent types, including the two new parameters (`ad_user_data` and `ad_personalization`), automatically. **Can I use this setup without Google Tag Manager?** This guide covers GTM-based implementation. If you are not using GTM, refer to the direct script installation guide in the Secure Privacy documentation. ## Related Articles - [How to Install Secure Privacy with Google Tag Manager](#) - [Blocking Cookies with Google Tag Manager](#) - [Google's EU User Consent Policy Requirements](#)
