Google Analytics 4 (GA4) Guide

Google Analytics 4 (GA4) Guide: Setup, Events, Key Events, SEO, Google Ads, Attribution & Reporting

Understanding website traffic is important, but knowing what visitors do after they arrive is even more valuable. Google Analytics 4 (GA4) helps Canadian businesses measure website activity, user journeys, leads, purchases and marketing performance.

At Intop Digital, we use analytics to help businesses make smarter decisions based on data not assumptions.

What Is Google Analytics 4?

Google Analytics 4 is Google's analytics platform for websites and apps. GA4 uses an event-based data model, meaning user interactions are measured as events.

Common events include:

• Page views

• Scrolls

• Button clicks

• Phone clicks

• Form submissions

• File downloads

• Signups

• Product views

• Add-to-cart actions

• Purchases

Events can include parameters that provide additional information, such as product names, revenue, page URLs, transaction IDs and campaign details.

For Canadian businesses, this makes GA4 useful for measuring everything from local lead generation to ecommerce sales.

How to Set Up GA4

A proper GA4 setup generally includes:

1. Create a Google Analytics account and GA4 property.

2. Create a Web data stream.

3. Add your GA4 Measurement ID to the website.

4. Install GA4 directly or through Google Tag Manager (GTM).

5. Configure important events.

6. Identify important business actions as Key Events.

7. Test tracking using DebugView.

8. Connect relevant marketing platforms such as Google Ads and Search Console.

Google Tag Manager is especially useful when a website needs multiple tracking configurations because tags can be managed without repeatedly editing website code.

Always Test Your Tracking

Installing GA4 doesn't guarantee accurate data.

Use DebugView and real-time reporting to confirm that important events are firing correctly.

Check for:

• Missing events

• Incorrect event names

• Duplicate events

• Incorrect parameters

• Events firing on the wrong pages

Fixing tracking problems early can prevent weeks or months of inaccurate reporting.

Understanding GA4 Key Events

One important GA4 terminology change happened in 2024.

Google changed the term "Conversions" to "Key Events" inside GA4.

A Key Event represents an important business action.

Examples include:

• Lead form submission

• Appointment request

• Quote request

• Phone click

• Newsletter signup

• Purchase

• Booking

Not every website interaction should be marked as a Key Event. Focus on actions that directly support business goals.

GA4 Key Events vs Google Ads Conversions

GA4 uses Key Events, while Google Ads continues to use Conversions.

GA4 Key Events can be imported into Google Ads, but numbers between the two platforms may not match exactly. Differences can occur because of attribution models, counting methods, conversion windows and platform reporting methodologies.

Understanding this difference is essential when preparing marketing reports.

GA4 Reports Marketers Should Use

GA4 contains many reports, but most businesses can focus on four important areas.

1. Acquisition

Acquisition reports show where users and sessions come from.

Common channels include:

• Organic Search

• Paid Search

• Direct

• Referral

• Organic Social

• Email

User Acquisition focuses on how users first arrived, while Traffic Acquisition focuses on the source of sessions.

2. Engagement

Engagement reports show what visitors do on your website.

Important metrics include:

• Views

• Engagement rate

• Average engagement time

• Landing pages

• Key Events

GA4 generally considers a session engaged when it lasts more than 10 seconds, contains a Key Event, or includes at least two page or screen views.

3. Monetization

Ecommerce businesses can use Monetization reports to measure:

• Product performance

• Add-to-cart activity

• Checkout activity

• Purchases

• Revenue

Ecommerce data requires proper implementation of events such as view_item, add_to_cart, begin_checkout and purchase.

4. Explorations

Explorations provide deeper analysis beyond standard reports.

Useful options include:

• Funnel Exploration

• Path Exploration

• Audience analysis

• Segment comparisons

These reports can help identify where users drop off and how they move through a website.

GA4 for SEO

GA4 can help SEO professionals understand what happens after organic visitors reach a website.

You can analyze:

• Organic traffic

• Landing pages

• Engagement

• Key Events

• Leads

• Revenue

For example, a page may generate significant organic traffic but very few enquiries. That could indicate an opportunity to improve the content, internal linking, calls to action or conversion experience.

For stronger SEO analysis, connect GA4 with Google Search Console to better understand organic search performance and landing-page behavior.

GA4 for Google Ads

If your Canadian business runs Google Ads, connecting GA4 can provide valuable post-click information.

Instead of measuring only:

• Impressions

• Clicks

• CPC

you can also analyze:

• Engagement

• Leads

• Purchases

• Revenue

• Landing-page performance

• User journeys

This helps businesses evaluate advertising based on business outcomes rather than traffic alone.

UTM Tracking

UTM parameters help GA4 identify marketing campaigns more accurately.

Common parameters include:

• utm_source

• utm_medium

• utm_campaign

• utm_content

• utm_term

Use consistent naming for campaigns across email, social media, paid campaigns and other marketing channels.

Poor UTM practices can make campaign reporting confusing and unreliable.

GA4 for Local Canadian Businesses

Local businesses can track valuable website interactions such as:

• Click-to-call

• Contact forms

• Appointment requests

• Booking clicks

• Service-page visits

• Location-page visits

• Messaging clicks

For a local business, traffic quality matters more than traffic volume.

A website receiving 300 highly relevant visitors can generate more business than one receiving thousands of visitors who never contact the company.

Privacy & Data Considerations

Canadian businesses should review their analytics implementation, consent practices, privacy policy and data-retention settings according to applicable privacy requirements.

Analytics should collect information necessary for legitimate measurement while avoiding unnecessary collection of sensitive personal information.

Businesses operating across multiple regions should also review the requirements that apply to their specific audiences and operations.

BigQuery & Advanced Analytics

Businesses with more advanced reporting requirements can export GA4 data to Google BigQuery.

This can enable deeper analysis by combining analytics data with information such as:

• CRM data

• Advertising costs

• Sales data

• Customer information

• Product data

This is particularly useful when standard GA4 reports aren't enough to answer complex business questions.

Common GA4 Mistakes

Avoid these common problems:

• Installing GA4 without testing it

• Marking every event as a Key Event

• Creating duplicate events

• Incorrect ecommerce tracking

• Inconsistent UTM parameters

• Ignoring attribution settings

• Comparing GA4 and Google Ads numbers without understanding differences

• Measuring traffic without measuring leads or revenue

• Ignoring mobile users

• Not connecting Google Search Console

• Not reviewing privacy and consent requirements
