GDPR Analytics Compliance
Meeting GDPR requirements for web analytics: lawful basis for processing, data minimization, purpose limitation, and — if using cookies — valid consent collection before tracking.
What does GDPR require from web analytics?
The General Data Protection Regulation (GDPR) applies to any processing of personal data of EU residents. For web analytics, the key requirements are:
- —Lawful basis — typically consent (Article 6(1)(a)) for cookie-based tracking, or legitimate interest for non-personal data collection
- —Data minimization — collect only what is necessary for the stated purpose
- —Purpose limitation — use the data only for the declared analytics purpose
- —Storage limitation — define and enforce data retention periods
- —Data subject rights — facilitate access, rectification, erasure requests
What does the ePrivacy Directive add?
Beyond GDPR, the ePrivacy Directive (Article 5(3)) requires consent before accessing or storing information on a user’s device — which includes setting cookies. This is why consent management platforms are required for cookie-based analytics.
How does cookieless analytics achieve compliance by architecture?
Cookieless analytics approaches compliance differently. By storing nothing on the visitor’s device, keeping no data that identifies anyone and reporting only in aggregate, it can rely on the audience-measurement exemption from ePrivacy consent, and GDPR obligations are minimal. This follows CNIL (France) and other EU authorities’ guidance on audience-measurement exemptions; in Germany the DSK does not extend the exemption to audience measurement.

- Consent Management Platform (CMP)Software that displays cookie consent banners and manages user preferences. Required under GDPR for websites using cookies or collecting personal data. What consent costs analytics varies by site: in our experience with clients, between 40% and 60% of traffic doesn't accept cookies.
- Analytics Data ResidencyThe geographic location where analytics data is processed and stored. Under GDPR, data residency determines which legal frameworks apply and whether cross-border data transfer mechanisms (like SCCs) are required.
- Cookieless AnalyticsWeb analytics that captures visitor data without using browser cookies, enabling traffic measurement that doesn't depend on consent status or cookie restrictions.
- First-Party Data CollectionCollecting analytics data through your own domain infrastructure rather than third-party servers. First-party requests are far less likely to be blocked by ad blockers and are not subject to third-party cookie restrictions.
