How to Set Up GTM Consent Mode in Magento 2

In this article, we will walk through each step of setting up Google Consent Mode in Tag Manager while configuring the Magento 2 Cookie Consent extension.

GTM Consent mode is a new feature presented by Google that helps manage how tags behave based on the consent status of your users in a more flexible way. This feature is replacing the deprecated “Associated Cookie Category” mode, allowing you to control each individual tag firing in GTM, instead of enabling/disabling the entire GTM when a visitor allows/denies the corresponding (associated) cookie category.

Please take the following steps to properly configure the GTM Consent Mode.

1. Set Up Your GTM Account

Create a GTM Account and Container

Important Information:

If your GTM account and the container are already created, skip this step and start adding new tags to the container.

Step-by-step guide:

  1. Go to and sign in to Google Analytics using your existing Google account associated with your business. Please note that you may be automatically authenticated if you are logged in to the Google account in your browser. In this case, click the Account icon and check whether you are using the correct account.
  2. Click Create Account to start creating a GTM account.

Important Information:

Consent mode was updated in November 2023 and now contains two additional consent types: ad_user_data and ad_personalization. If you already use consent mode, upgrade your Magento to Consent Mode v2 by March 2024 to comply with the latest privacy regulations and ensure that data about new EEA users will be captured.
To ensure compliance with Consent Mode V2, please make sure that your Cookie Consent extension is version 1.11.2 or later. The newly introduced consent types are automatically assigned to cookie categories. However, if you have any customizations in place, please verify that the assigned cookie categories are accurate.

Step-by-step guide:

  1. In the Magento admin panel, go to Plumrocket -> Cookie Consent extension -> Configuration.
  2. Scroll down to the Google Tag Manager Settings tab -> Consent Types section.
  3. Set Cookie Categories for the Consent types that you added in the Tag Configuration section. In our example, we set the Marketing Cookies and Statistics Cookies categories for the ad_storage and analytics_storage content types accordingly.
  4. Click Save Config.
