What the Google Consent Mode check looks for
- Default consent state is set before any Google tag fires.
- The CMP updates Consent Mode when the visitor makes a choice.
- Both analytics_storage and ad_storage signals are handled, not just one.
- Consent Mode v2 parameters (ad_user_data, ad_personalization) are present.
About Google Consent Mode
Google Consent Mode adjusts how Google tags (GA4, Google Ads) behave based on the visitor’s consent choices. When consent is denied it sends cookieless “pings” that let Google model conversions without storing identifiers.

Google Consent Mode setup FAQ
Consent Mode is the single most commonly mis-wired part of a GTM setup — the default state or the CMP hand-off is often missing, so consent signals never reach Google. TagStack checks the wiring in one scan.
