Google Analytics

Google Analytics is the analytics tool that virtually every agency uses, whether for their own website or for client reporting. The transition to GA4 brought a more flexible event-based data model that better captures user journeys across devices and platforms. For agencies, the ability to set up custom events, track conversions, and attribute revenue to specific campaigns makes GA4 indispensable for demonstrating marketing ROI to clients.

Agencies particularly benefit from GA4's integration with the broader Google ecosystem. Campaign data flows in from Google Ads, organic search performance connects via Search Console, and audiences can be shared with ad platforms for remarketing. This tight integration means agencies running Google Ads campaigns can track the full funnel from click to conversion without leaving the Google ecosystem. The Explorations feature also lets agencies build custom analysis reports that go far beyond the standard templates.

Compared to privacy-focused alternatives like Plausible or Fathom, Google Analytics offers vastly more analytical depth but comes with significant privacy considerations. European agencies in particular need to carefully configure GA4 for GDPR compliance, including consent management and data retention settings. For agencies that want simple, cookie-free analytics, Plausible is increasingly popular. But for the full picture of user behavior, campaign performance, and conversion attribution, Google Analytics remains the tool that clients expect to see in their monthly reports.
