Google Consent Mode v2

If your site uses Google Analytics 4, Google Ads or GTM, you should enable Consent Mode v2 — since March 2024 Google requires it for ads personalization and audience features in the EEA.

Enable it under Cookie Consent → Settings → Google Consent Mode. It is off by default, because without a Google tag setup it would only emit unused consent calls.

What the package does

When enabled, the middleware injects a consent default snippet before any Google tags load:

gtag('consent', 'default', {
  'ad_storage': 'denied',
  'ad_user_data': 'denied',
  'ad_personalization': 'denied',
  'analytics_storage': 'denied',
  'functionality_storage': 'denied',
  'personalization_storage': 'denied',
  'security_storage': 'granted',
  'wait_for_update': 500
});
gtag('set', 'ads_data_redaction', true);
gtag('set', 'url_passthrough', true);

When the visitor makes a choice, the package sends a gtag('consent', 'update', …) with the granted signals.

Category mapping

Consent categories map to Consent Mode signals as follows:

Banner category	Consent Mode signals
Analytics	`analytics_storage`
Marketing	`ad_storage`, `ad_user_data`, `ad_personalization`
Preferences	`functionality_storage`, `personalization_storage`
Necessary	`security_storage` (always granted)

Note the mapping is not 1:1 — marketing consent drives three signals, which is exactly what Google’s v2 requirements expect.

Basic vs Advanced mode

Both are supported; the difference is how you load your Google tags:

Basic: add your Google tags as managed scripts in a consent category. Tags load only after consent — no data reaches Google before that, not even cookieless pings.
Advanced: load Google tags unconditionally (e.g. GTM in your template). Before consent, tags send cookieless pings; after consent, full measurement. Gives Google modelling data but sends some data pre-consent — make a deliberate choice here and document it in your privacy policy.

For most Danish/EU sites Basic mode is the safer default; choose Advanced only if you rely on Google’s conversion modelling.
