SealMetrics vs Google Analytics 4
A comparison based on data, not opinion. Both tools measure web traffic — but they capture fundamentally different amounts of it. Here is why GA4 shows only 13% of EU traffic, and what that means for your business decisions.
Average EU data capture rate. Depends on cookie consent, browser support, and absence of ad blockers. Every decision is based on a fraction of reality.
Full data capture regardless of consent status, browser, or ad blocker. No cookies, no dependencies. Decisions grounded in complete data.

When to use each
GA4 works well when
- —Your audience is primarily outside the EU
- —Consent rates are above 80%
- —You need deep Google Ads integration above all else
- —Approximate data is acceptable for your decisions
- —Budget is the primary constraint (GA4 is free)
SealMetrics is better when
- —You operate in the EU and consent rates are below 50%
- —Accurate attribution drives budget allocation decisions
- —You need GDPR compliance without ongoing configuration
- —Your data must stay in the EU — no exceptions
- —You want to see 100% of traffic, not a consent-dependent fraction
- —You need AI agent tracking alongside human analytics (Coming Soon)
The real comparison is with GA360.
GA4 is free — and for many businesses, “free” is the right price for approximate data. But if your marketing budget depends on accurate attribution, the real question is whether to invest in GA360 ($150,000+/yr), Adobe Analytics ($100,000+/yr), or SealMetrics (from €599/mo). Under GDPR Article 6, consent is required when personal data is processed — which is why consent banners destroy analytics data.
SealMetrics delivers enterprise-grade analytics — complete data capture, AI supervision, multi-touch attribution — at a fraction of enterprise pricing. With capabilities that GA360 and Adobe do not offer: cookieless collection, AI agent tracking (coming soon), and GDPR compliance by design.

Frequently asked questions
Does SealMetrics capture more data than GA4 in the EU?
Yes. GA4 captures approximately 13% of real EU traffic due to consent rejection (55%), ad blockers (40%), and browser restrictions. Even among the 45% who accept cookies, 65% accept on the second page view — after the landing page where the traffic source is captured. Only ~16% of visitors have correct attribution. SealMetrics captures 100% because it uses no cookies, no third-party requests, and requires no consent for basic analytics.
Is SealMetrics GDPR compliant without a consent banner?
Yes. SealMetrics collects zero personal data and uses no cookies or device storage. Under GDPR Article 6(1)(f) and the ePrivacy Directive, consent is not required when no personal data is processed and no device storage is accessed. The French CNIL and UK ICO have confirmed this approach for cookieless analytics.
Can I run SealMetrics alongside GA4?
Yes. Most customers run both tools in parallel during evaluation. SealMetrics operates independently — it does not conflict with GA4, Tag Manager, or consent mode. The side-by-side comparison typically shows SealMetrics reporting 3-8x more visitors than GA4 in EU markets.
Why is GA4 free while SealMetrics costs €599/month?
GA4 is free because Google monetizes the data through its advertising ecosystem. SealMetrics is an independent, EU-based analytics platform with no advertising business model. The €599/mo Growth plan includes core analytics, API, LENS AI, BigQuery, 5M events/month, and EU-only data residency. Annual billing starts at €499/mo.
Does SealMetrics work with ad blockers?
Yes. SealMetrics operates as first-party infrastructure on your own domain. Ad blockers target third-party analytics requests (like google-analytics.com). Because SealMetrics data flows through your domain, it is invisible to ad blockers.
