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
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 €199/mo).
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, and GDPR compliance by design.
