Google Consent Mode v2, configured and tested on your store
I implement Consent Mode v2 so Google tags adjust their behaviour to each visitor's choice and GA4 and Google Ads receive the right consent signals.
In short
Google Consent Mode v2 is the mechanism that tells Google tags the visitor's consent state through four parameters: ad_storage, analytics_storage, ad_user_data and ad_personalization. I decide whether your store should run basic or advanced mode, set up the default state and the update from your CMP, and validate everything in GA4 and Google Ads. It is for WooCommerce stores that advertise with Google and sell into the European Economic Area.
Common Consent Mode problems
-
Only half the signals in place
The store sends ad_storage and analytics_storage but is missing ad_user_data and ad_personalization, the two parameters added in version 2.
-
Default state set too late
The default command runs after tags have loaded, so the first requests go out with no consent state at all.
-
A mode nobody chose
No one consciously decided between basic and advanced mode, so the store either loses modelling or sends pings it never meant to send.
How I implement Consent Mode v2
The first step is deciding with you between basic mode, where tags load only after consent, and advanced mode, where they send cookieless signals while consent is denied. That choice depends on your appetite for risk and should be checked with whoever advises you on legal matters.
- Default state set before any Google tag fires
- Consent updates passed from the CMP without delay
- Region-specific defaults when you sell into several markets
- Signals validated in Tag Assistant, GA4 and Google Ads

What is the difference between basic and advanced mode?
In basic mode, Google tags do not load until the visitor consents. In advanced mode, they load with consent denied by default and send cookieless signals that Google can use to model conversions. The choice has privacy implications and should be made with your eyes open.
Is Consent Mode v2 diretrizry?
Google requires valid consent signals for users in the European Economic Area to keep certain measurement and advertising features available. That is a Google requirement rather than a legal obligation in itself. The legal duty to collect consent comes from the European privacy framework.
Does it also cover the Meta pixel and other platforms?
Consent Mode is a Google mechanism and only directly controls Google tags. For Meta, TikTok or Klaviyo, firing has to be conditioned in GTM or handled through each platform's own consent options. I cover that in the consent-based event conditioning service.
