Are the cookies "_ga" and "_GA_XXXXXXXX" stored by Webflow for GTM tracking purposes or do they track user behavior, potentially breaching GDPR regulations?
TL;DR
_gaandGAXXXXXXXXcookies are set by Google Analytics (via Webflow's GA integration or GTM) to track user behavior.- Under GDPR, they require explicit, logged user consent before activation, which must be implemented by the site owner using a compliant cookie management system and configured consent triggers in GTM or GA.
The cookies _ga and GAXXXXXXXX are not set by Webflow itself but by Google Analytics, typically loaded via Google Tag Manager (GTM), and can have GDPR implications based on how they're used.
1. Who Sets These Cookies
_gaandGAXXXXXXXXare standard cookies used by Google Analytics (GA4).- These cookies are not natively set by Webflow; they appear only if you’ve enabled Google Analytics, either:
- Directly in Webflow Site Settings, or,
- Indirectly via Google Tag Manager code you've installed.
2. Purpose of These Cookies
_ga: Used to distinguish unique users by assigning a randomly generated client ID. This helps track user behavior across sessions.GAXXXXXXXX: Session-specific data used by GA4 to store session state and other persistent user data.- Both are set for user behavior tracking.
3. GDPR Compliance Implications
- Under GDPR, cookies for user tracking (like those from GA) are considered non-essential.
- Therefore, explicit user consent is required before these cookies are set. Consent must be:
- Opt-in (not pre-enabled),
- Granular (user chooses cookie categories),
- Logged (with timestamp and IP anonymization if needed).
4. Webflow's Role and Responsibility
- Webflow does not automatically set these cookies.
- If you use Webflow’s built-in Google Analytics integration, GA cookies are set unless you manage consent externally.
- If you're adding GTM snippets in Webflow, it’s your responsibility to configure consent (e.g., via a cookie banner like Cookiebot or Fathom).
5. How to Make It GDPR-Compliant
- Use a compliant cookie management system, such as:
- Cookiebot, OneTrust, or Complianz (integrated via GTM or embedded manually).
- Modify GTM or GA trigger settings so tracking only runs after consent.
- Avoid auto-adding tracking tags until users provide approval.
Summary
The _ga and GAXXXXXXXX cookies are set by Google Analytics, not Webflow. They do track user behavior, meaning they require explicit consent under GDPR. If you're using GTM or direct GA integration on Webflow, you must ensure a compliant consent mechanism is in place.
