Advance Consent Mode (GCM) V2 :
User visits websites
Google tags will load
Consent banner will collect the consent status of the user and
Consent Mode will communicate it
...
User rejects
Google tags adjust
With an advanced implementation of consent mode, tags will adjust their behaviour to respect the status received from each parameter.
Consent Mode detects user <– choice and communicate –> that choice to Google tags
...
User consents
Google tags behave as normal (firing)
Basic Consent Mode (GCM)
User visits websites
Google tags are blocked until consent is communicated via consent banner
Consent banner appears
...
User rejects
Google tags stay blocked
With a basic implementation of consent mode, tags do not fire and no data is shared with Google.
<– Consent Mode –>
User consents
...
Consent Mode detects that user has consented and communicates it to Google tags

How Google Tag Manager (GTM) handles consent
Feature | Basic consent mode | Advanced consent mode |
|---|---|---|
Tag loading | Blocked until user interaction with a consent banner. | Loads with defaults set to denied, unless configured otherwise. |
Data transmission | No data is sent before a user consents - not even the default consent status. | When consent is denied, consent state and cookieless pings are sent. |
Consent states | Set after user interaction. | Defaults set to denied, unless configured otherwise; updates based on user choice. |
Tag behavior after user interaction | Loads and executes consent mode APIs only when a user grants consent. | Adjusts tag behavior based on user consent choice. |
Conversion modeling | General model (less detailed modeling). | Advertiser-specific model (more detailed modeling). |
Advanced vs Basic Google Consent Mode (GCM) - Overview
The following overview graphic will help you get a quick overview of the differences between Advanced and Basic GCM.
...
In the sections below, you’ll find more details on setting them up with the Usercentrics CMP.
Basic Google Consent Mode
Google tags are initially blocked until consent is granted.
Using the Usercentrics CMP, tags within the Google Tag Manager (GTM) will need to be triggered only when consent for the correlating Data Processing Service (DPS) is given.
How we recommend setting up variables & triggers for this purpose in the GTM is documented.
Alternatively to using our recommended variable & trigger setup that can fire specific tags based on the consent status of specific Data Processing Services (DPS) in the Usercentrics CMP Configuration / SettingID, there are also other options of handling the triggering of tags, f.ex.
Triggering tags based on the consent state(s) of Google Consent Mode storage types (i.e. ad_storage) is possible for individual tags. The following video outlines this method for setting up Basic Google Consent Mode in more detail:
...
Third party templates may be used to “translate” the consent_status event of the Usercentrics CMP into signals for the Google Consent Mode storage types inside the GTM.
While these alternative approaches are possible to set up in connection with the Usercentrics CMP, they are not part of the generally recommended setup. They often require the assistance of a GTM expert.
Advanced Google Consent Mode
Google tags of relevant Google services are loaded before consent is collected.
They will not be adjusted like we recommend for other non-essential tags. Instead they will trigger “normally”, i.e. like so in the GTM:
The Google tags have built-in consent checks for one or more of the following Google Consent Mode storage types:
ad_storagead_user_dataad_personalizationanalytics_storage
Example:
The tags will adjust their behavior accordingly.- Important: Tags corresponding to non-essential, non-Google Data Processing Services (DPS) should continue to be adjusted as generally documented. The Advanced Google Consent Mode implementation described above is specifically for Google tags of relevant Google services.
