What is Google Analytics?

Google Analytics (GA4 is the current version) provides a comprehensive view of your website's performance by tracking user interactions — page views, sessions, scroll depth, button clicks, form submissions, purchases — and attributing them to traffic sources. At its core, it answers the fundamental questions every website owner needs to understand: how many people are visiting, from where, and what are they doing?

Beyond basic traffic reporting, Google Analytics enables goal tracking (measuring how many users complete specific conversions), audience analysis (demographics, interests, devices, and geography of your visitors), acquisition analysis (which channels — organic search, paid, social, direct, email — are driving the most valuable traffic), and behavior flow analysis (the paths users take through your site, including where they drop off).

GA4 (the current generation, launched in 2020 to replace Universal Analytics) introduced an event-based data model that tracks any user interaction as an "event" rather than the session-based pageview model of its predecessor. GA4 also integrates more natively with Google Ads for conversion tracking and audience creation. Setting up GA4 correctly — with proper goal tracking and filtered views — is the prerequisite for any meaningful marketing analytics work.
