Digital marketing course (GA4, GTM)

Follow the steps in the exact order below.
Each step builds on the previous one and skipping steps may result in no data being collected.

Step 1: Admin settings

• In GA4, go to Admin → Data streams

• Click Add stream

• Select the platform:

  • Website

  • Android app

  • iOS app

👉 For this course, always select Website.

Step 2 – Setting Up a Web Data Stream

• Enter your Website URL

• Enter a clear Stream name (e.g. E-shop – test site)

• Click Create and continue

Step 2a – Enable Enhanced Measurement (Very Important)

• Make sure Enhanced measurement is switched ON

• Click the ⚙️ icon to review individual events

Enhanced measurement automatically tracks:

• Page views

• Scrolls

• Outbound clicks

• Site search

• Form interactions

• Video engagement

• File downloads

Step 3 – Your Unique Measurement ID (Key Concept)

On the Web stream details screen, you will find:

• Measurement ID (format: G-XXXXXXXXXX)

• Stream URL

• Stream name

What the Measurement ID Is

The Measurement ID is:

• a unique identifier for your GA4 data stream

• the “address” where your website sends data

Step 3a – Understanding the GA4 Script Code

GA4 provides a gtag.js tracking script, for example:

What This Code Does

• Loads Google Analytics tracking library

• Creates a data layer

• Sends page view and event data to GA4

• Connects data using your Measurement ID
  
  

Step 4 – Implementing GA4 on Different Platforms

GA4 can be implemented in different ways depending on the platform.

WordPress - Google Tag Manager plugin or GA4-specific plugin (e.g. Site Kit by Google)

Shopify - Use Shopify Google channel or insert GA4 via Google Tag Manager

Shoptet - GA4 Measurement ID can be added in Shoptet administration

Wix - GA4 can be connected via Marketing Integrations

Before considering this activity complete, you must verify that GA4 is actively collecting data. Open your website in a new browser tab and perform at least one action such as loading a page, clicking a link, or scrolling, then return to Google Analytics 4 and navigate to Reports → Real-time. If you see at least one active user and events appearing in real time, your implementation is working correctly; if not, check that the Measurement ID is correct, the tracking code is properly installed, analytics consent is enabled, and allow a few minutes for data to appear. Once real-time data is visible, your GA4 setup is successfully completed and the job is done—you are now ready to begin analyzing real user behavior.
