⚙️ How Google Analytics Works (Step-by-Step)

1. Data Collection

Tracking Code: When you set up Google Analytics, you install a small piece of JavaScript code (the “tracking tag”) on every page of your website or in your mobile app. This code collects data about each visitor’s interactions.
Cookies and Device Data: The code uses cookies and device information to identify users, track sessions, and gather details about their behavior, such as pages viewed, time spent, and actions taken.
Event-Based Tracking (GA4): In Google Analytics 4, all user interactions are tracked as “events”—including page views, clicks, downloads, video plays, purchases, and more.

2. Data Processing

Data Transmission: The tracking code sends the collected data to Google’s servers, where it is processed and organized into meaningful metrics and dimensions.
User & Session Identification: Google Analytics processes the data to distinguish between users (unique visitors) and sessions (individual visits), using cookies, device IDs, or user IDs for logged-in users.
Attribution & Segmentation: The platform attributes actions to specific traffic sources and segments users based on their behavior, demographics, and acquisition channels.

3. Data Configuration

Filters & Settings: Before data is finalized, Google Analytics applies any filters or configurations you’ve set up (such as excluding internal traffic, grouping pages, or defining goals).
Custom Events & Goals: You can define custom events and conversion goals to track specific actions that matter to your business (e.g., newsletter sign-ups, product purchases).

4. Reporting & Analysis

Dashboard & Reports: Processed data is presented in interactive dashboards and reports, accessible through the Google Analytics web interface or via reporting APIs.
Standard & Custom Reports: View standard reports (audience, acquisition, behavior, conversions) or build custom reports to focus on your unique KPIs.
Real-Time Insights: Monitor live user activity and campaign performance as it happens.
Data Export & Integration: Export data or integrate it with other tools for deeper analysis and visualization.

Increase Conversions: Track and optimize conversion funnels, from initial visit to final purchase or sign-up.
