Google Analytics

Google Analytics 4 (GA4) is the current generation of Google's analytics platform, which fully replaced Universal Analytics in July 2024. It serves as the industry-standard web and app analytics solution, deployed on over 28 million active websites and representing roughly 85% market share among analytics tools.

GA4 fundamentally restructured how data is collected and processed compared to its predecessor. Instead of session-based tracking, GA4 uses an event-based data model where every user interaction—page views, clicks, scrolls, purchases—is captured as an individual event with customizable parameters. This shift enables more flexible analysis and better cross-platform tracking between websites and mobile apps within a single property.

Core capabilities include real-time reporting dashboards, audience segmentation based on demographics and behavior, conversion tracking with customizable goals, funnel analysis showing where users drop off, and path exploration reports that visualize user journeys. The Explorations workspace provides advanced analysis techniques including free-form reports, cohort analysis, and segment overlap analysis.

One of GA4's most significant additions is its integration of Google's machine learning models. Predictive metrics such as purchase probability, churn probability, and predicted revenue allow marketers to build audiences of users likely to convert or leave within the next seven days. Anomaly detection automatically flags unusual changes in metrics, and GA4 surfaces automated insights that highlight trends and opportunities without manual analysis.

GA4 is designed with a privacy-centric approach, using data modeling and machine learning to fill gaps when cookies or identifiers are unavailable. It supports consent mode, which adjusts data collection behavior based on user consent status, and offers data retention controls that let administrators set retention periods between 2 and 14 months for user-level data. Server-side tagging through Google Tag Manager provides additional control over what data leaves the browser.

The platform integrates natively with Google Ads, Google Search Console, BigQuery, Looker Studio, and Google Merchant Center. BigQuery export—available for free to all GA4 users—enables raw event-level data analysis using SQL, a feature previously restricted to the paid GA360 tier. Third-party integrations are supported through the GA4 Measurement Protocol API and Data API.

GA4 360, the enterprise tier available through the Google Marketing Platform, extends the free version with higher data limits (up to 125 million events per month versus 10 million for free), 50 custom dimensions instead of 25, sub-property and roll-up property support, data-driven attribution modeling, and a guaranteed SLA with dedicated support. GA4 360 pricing is negotiated per contract and typically starts around $50,000 per year, scaling with data volume.

As of early 2026, GA4 continues to receive significant updates, including enhanced integration with Google's AI tools, improved e-commerce tracking templates, expanded consent mode v2 support for EU compliance, and refined cross-device measurement using Google Signals.
