Understanding GA4 and Why It Matters in 2025

1. What Is GA4?

Google Analytics 4, or GA4, is Google’s latest platform for tracking how people use your website or app. The old version, Universal Analytics, stopped working in 2023. GA4 is now the only version supported worldwide.

GA4 measures everything with events, not sessions. This makes data more flexible, more accurate, and easier to understand. It also works across devices, which is important because people switch between phones, laptops, and apps all day.

This GA4 Setup Guide will help you learn what GA4 does, how it collects data, and how you can set it up the right way.

2. Why Google Created GA4

There are four major reasons why GA4 replaced Universal Analytics:

1. Privacy laws changed.

Countries now require strict privacy controls. GA4 follows these laws.

2. People use many devices.

One user may switch between a laptop and a phone. GA4 tracks the full journey.

3. Machine learning helps fill gaps.

With data loss increasing, GA4 uses predictive modelling to give cleaner insights.

4. Marketers need deeper insights.

GA4 tracks content, clicks, scrolls, conversions, and funnels, without extra code.

This GA4 Setup Guide makes these features easy to understand, even if you’re new to analytics.

3. Main Features of GA4 (Explained Simply)

A beginner should know these features before setup:

Event-Based Tracking

Everything is an event: page views, scrolls, clicks.

Enhanced Measurement

GA4 auto-tracks:
• scrolls
• outbound clicks
• file downloads
• video engagement
• site search

Realtime Reports

See live users on your site.

Engagement Metrics

GA4 replaces bounce rate with engagement rate.

Cross-Device Tracking

One user → one journey → clearer reports.

Conversion Flexibility

You choose what counts as a conversion.

Predictive Metrics

Such as purchase probability and churn risk.

These features are the base of this GA4 Setup Guide. Once you understand them, setup becomes easy.

4. Who Should Use GA4?

Anyone with a website or app should use GA4:

• bloggers
• business owners
• marketers
• developers
• eCommerce stores
• agencies
• students learning digital marketing

GA4 is free, powerful, and beginner-friendly—especially when guided with a simple GA4 Setup Guide like this one.

Step-by-Step GA4 Setup Guide (Beginner Friendly)

STEP 1 — Create Your GA4 Account

Follow these simple steps:

  1. Go to analytics.google.com
  2. Click Start Measuring
  3. Create a new account
  4. Name your property
  5. Select your reporting time zone
  6. Choose your currency
  7. Click Next

Now your GA4 property is created.

STEP 2 — Add a Data Stream

A data stream is the source of your website or app data.

For a website:

  1. Choose Web
  2. Enter your website URL
  3. Enter a stream name
  4. Enable Enhanced Measurement
  5. Click Create Stream

Your stream will generate a Measurement ID (G-XXXXXXX).
You will use this ID in the next step of this GA4 Setup Guide.

STEP 3 — Install GA4 on Your Website

You can install GA4 in 3 ways:

1. Google Tag Manager (Recommended for beginners)

Steps:

  1. Open GTM
  2. Click Tags → New
  3. Choose GA4 Configuration
  4. Paste your Measurement ID
  5. Trigger: All Pages
  6. Save and publish

This method is clean, safe, and future-proof.

2. Manual Install (For Developers)

Paste the GA4 tracking script in the <head> section of your website.
This method is direct but harder to maintain.

3. Plugin Install (WordPress users)

Install a plugin like:

• Site Kit
• MonsterInsights
• GA Google Analytics

Paste your Measurement ID and connect.

STEP 4 — Check Realtime Data

To confirm your setup:

  1. Open GA4
  2. Go to Reports → Realtime
  3. Visit your website in another tab

If you see yourself appear, your GA4 Setup Guide steps worked perfectly.

STEP 5 — Turn on Enhanced Measurement

Enhanced Measurement auto-tracks:

• scrolls
• outbound clicks
• file downloads
• video views
• site search
• form interactions

Go to Admin → Data Streams → Web Stream → Enhanced Measurement.

Turn everything ON.
This makes GA4 more powerful without extra tags.

STEP 6 — Set Up Key Events

Events help track behavior.
To create custom events:

  1. Go to Admin → Events
  2. Click Create Event
  3. Add conditions (example: button click)
  4. Save

Events make your GA4 Setup Guide complete and data-rich.

STEP 7 — Mark Conversions

Anything can be a conversion:

• lead form submission
• add to cart
• purchase
• signup
• phone click

To mark a conversion:

  1. Go to Events
  2. Turn on the toggle next to your event

In Universal Analytics, conversions were called “goals.”
In GA4, they are simply events marked as conversions.

STEP 8 — Link Google Products

Link once for better data:

• Google Ads
• Google Search Console
• BigQuery
• Merchant Center

This makes GA4 smarter and more accurate.

Using GA4 After Setup (Reports + Insights)

1. See Where Traffic Comes From

Go to:

Reports → Acquisition → Traffic Acquisition

This shows:
