Google Consent Mode V2 (GCM V2) - Automatic integration
What Is Google Consent Mode V2 and how to set it?
Google Consent Mode (GCM) helps websites adjust how Google tags behave based on a visitor’s cookie consent choices—supporting compliance with regulations like GDPR.
It works by sending consent signals to Google without requiring cookies, allowing for continued measurement even when users don’t give full consent.
Advanced vs. Basic Consent Mode
🚀 Advanced Mode (recommended)
- Google tags load immediately when the page loads.
- Tags assume consent is denied by default and send cookieless pings.
- When consent is later granted, full tracking is activated.
- Provides advertiser-specific conversion modeling for more accurate insights.
✅ Basic Mode
- Google tags are blocked until the user interacts with the consent banner.
- If consent is granted, tags fire and send consent state to Google.
- If denied, no tags or data are sent at all.
- Google uses a generalized model for conversions if data is missing.
What Are Cookieless Pings?
Even if a user denies consent, advanced mode allows for limited data to be sent to Google via cookieless pings, such as:
- Page visits, referrer, and user agent
- Consent state info (granted or denied)
- Ad click info (if available)
- Randomized session data
This helps maintain partial measurement while respecting user privacy.
Consent States & Tag Behavior
- Consent state is set dynamically based on the user’s banner interaction.
- Tags adjust automatically based on whether ad_storage or analytics_storage are allowed.
- With full consent, all Google tags behave normally.
