What Is Google Analytics?
Google Analytics (GA) is the world's most widely used web analytics platform, provided free of charge by Google. With the current version Google Analytics 4 (GA4), Google has fundamentally redesigned the entire tracking model: instead of page-based tracking, an event-based data model now takes center stage.
Google Analytics 4: The New Data Model
GA4 is built on events rather than sessions and pageviews. Every user interaction – whether page view, click, scroll, or form submission – is captured as an event. This model enables more flexible and detailed analysis of user behavior across different platforms, including websites and apps.
Key GA4 concepts:
- Events: The building blocks of tracking – automatically collected (page_view, scroll), recommended (file_download, video_start), or custom
- Conversions: Marked events representing business-critical actions
- Audiences: User segments based on behavior, demographics, or technology
- Explorations: Flexible analysis reports for deeper investigation
- Engagement Metrics: Engaged sessions, engagement rate, and average engagement time as new core metrics
GDPR-Compliant Setup
Privacy-compliant implementation of Google Analytics requires several measures:
- Cookie Consent: Tracking may only start after explicit user consent
- IP Anonymization: Enabled by default in GA4 with correct configuration
- Data Retention: Limit the period to the minimum (2 or 14 months)
- Google Signals: Disable if needed to avoid collecting extended demographic data without consent
- Data Processing Agreement: Signing a DPA with Google is mandatory
Google Analytics and Google Tag Manager
For professional implementation, Google Analytics is typically integrated via the Google Tag Manager (GTM). GTM allows centralized management of tracking codes without needing to modify website code for every change. Through GTM, Enhanced E-Commerce Tracking, custom events, and third-party tags can also be coordinated.
Typical Analysis Scenarios
In daily marketing work, Google Analytics answers questions such as:
- Which acquisition channels bring the most valuable users?
- Where do users drop off in the conversion funnel?
- Which content formats generate the highest engagement rate?
- How does user behavior differ on mobile devices versus desktop?
- Which campaigns achieve the best return on ad spend?
