Google Analytics

Web analytics · 6の代替ツール

Site analytics for operators. Google Analytics (GA4) connects visitor behavior to Google’s ad ecosystem.

なぜ Google Analytics から離れる?

EU regulators have challenged GA use in several countries (e.g. Austria, France). It drives cookie banners and imposes privacy cost on visitors.

Googleの限界・リスク

  • Visitor data sent to Google servers (mainly U.S.)—third-country transfer risk
  • Cookies and fingerprinting complicate GDPR consent
  • GA4 is complex and often overkill for small sites
  • You depend on Google policy changes and shutdown risk (Universal Analytics precedent)
