Google Analytics 4 (GA4) is now the default analytics platform from Google — replacing Universal Analytics forever. Whether you run a business, manage an SEO campaign, or analyze user behaviour, GA4 is the most powerful tool to measure performance across websites and apps.
This guide covers everything about GA4, including setup, features, reports, conversions, events, funnels, audiences, monetization tracking, and advanced insights.
Let’s dive in.
What is Google Analytics 4 (GA4)?
Google Analytics 4 is Google’s latest analytics platform designed to help businesses measure user interactions across websites, apps, and multiple devices. Unlike Universal Analytics (UA), GA4 is built on an event-based tracking model, giving more flexibility and deeper insights into user behaviour.
