Understanding your event marketing with Google Analytics 4

Google Analytics 4 (GA4) helps you understand how people discover your event, how they interact with your website, and what convinces them to complete an entry.

Written by Angus Williams

Think of GA4 as answering three simple questions:

  1. Where did my visitors come from?

  2. What did they do?

  3. Did they complete an entry?

Once you know these answers, you can spend more time promoting what works and less time on activities that don't.


Before You Begin

It's important to remember that more visitors doesn't always mean more entries.

Imagine:

  • 500 people visit from Facebook and 5 enter.

  • 100 people visit from an email newsletter and 20 enter.

Facebook sent more traffic, but email produced far more participants.

GA4 helps you spot these differences.


The Reports You'll Use Most

1. Reports Snapshot

This is your dashboard.

It gives you a quick overview of:

  • Website visitors

  • New users

  • Entries (Purchases)

  • Revenue

  • Where visitors came from

Use it for:

A quick health check after launching marketing.

Ask yourself:

  • Are visits increasing?

  • Are bookings increasing too?

  • If visits are rising but bookings aren't, something may need improving.


2. Acquisition Reports

(Where people came from)

This is one of the most valuable reports for event organisers.

You'll see visitors arriving from channels such as:

  • Google Search

  • Facebook

  • Instagram

  • Email campaigns

  • Direct visits

  • Other websites

For each channel you'll see things like:

  • Users

  • Sessions

  • Purchases

  • Revenue

What conclusions can you draw?

If Google Search creates lots of bookings:

→ Invest more in SEO.

If email produces the highest conversion rate:

→ Send more newsletters.

If paid advertising brings visitors but very few entries:

→ Review your adverts or landing page.


3. Engagement Reports

(What visitors actually did)

These reports show how people interacted with your pages.

You'll see information including:

  • Which pages people visited

  • Average engagement time

  • Number of page views

  • Events completed

This helps answer questions like:

  • Are people reading about the event?

  • Are they leaving immediately?

  • Which pages are most popular?


4. Ecommerce Reports

(Bookings and revenue)

This is where you'll find completed entries.

You'll see:

  • Number of bookings

  • Revenue

  • Average booking value

  • Items purchased

For most organisers, this becomes the most important report because it tells you whether your marketing is actually generating entries.


What Eventrac Tracks For You

We've already configured Google Analytics so your booking journey can be tracked across your website and Eventrac pages using cross-domain tracking. This means a visitor remains the same person throughout the booking process, rather than appearing as two separate visits.

The following information is automatically tracked.

Page Views

Every stage of the booking process records a page view.

This lets you see:

  • How many people started booking

  • Which booking pages were viewed

  • Where visitors dropped out


Completed Bookings (Purchases)

When someone successfully enters your event, GA4 records a Purchase event.

This is your primary conversion.

You can see:

  • Total bookings

  • Revenue generated

  • Number of transactions


Booking Value

Every booking includes its total value.

This allows you to understand:

  • Revenue generated by different marketing channels

  • Average booking value

  • Return on advertising spend


Ticket Types

GA4 also records the products (tickets) purchased.

For example:

  • Marathon Entry

  • Half Marathon Entry

  • Junior Race

This helps you understand which ticket types are most popular.


Transaction ID

Every booking receives a unique transaction ID.

This allows Google Analytics to accurately count completed entries without duplication.


Marketing Attribution

Because cross-domain tracking is enabled, Google Analytics can correctly attribute bookings to the marketing source that brought the participant to your event.

For example:

Someone clicks:

Instagram → Event Website → Booking Form → Checkout

The completed booking is still credited to Instagram rather than appearing as a direct visit.


Social Media & Campaign Tracking

If you create separate tracking links for different campaigns (for example Facebook, Instagram, newsletters or partner organisations), you'll be able to compare exactly which campaigns generated the most entries. Eventrac's tracking links also work alongside UTM parameters for deeper GA4 reporting.

Instead of asking:

"Did Facebook work?"

You can answer:

  • Facebook generated 48 bookings.

  • Instagram generated 21 bookings.

  • Email generated 63 bookings.

  • Google Search generated 39 bookings.

This makes it much easier to decide where to focus your marketing budget and effort.


Questions You Can Answer Using GA4

Once your tracking is set up, you'll be able to answer questions like:

  • Which marketing channel brings the most bookings?

  • Which channel generates the most revenue?

  • Which pages are most popular?

  • Which ticket types sell best?

  • Are more people booking this month than last month?

  • Are visitors reaching the booking page but not completing an entry?

  • Which campaigns are worth repeating next year?


A Simple Monthly Check

You don't need to look at GA4 every day. A monthly review is often enough.

Take 10 minutes to answer these questions:

Question

Where to look

How many people visited my event?

Reports Snapshot

How many completed an entry?

Ecommerce Reports

Which marketing channel generated the most bookings?

Acquisition Reports

Which pages were most popular?

Engagement Reports

Ecommerce Reports


Remember

Google Analytics doesn't tell you what to do—it gives you the information to make better decisions.

The goal isn't to collect lots of data. It's to answer simple questions like:

  • Which marketing is working?

  • Where should I spend my time?

  • What's helping more people enter my event?

Once you can answer those questions, you'll be making marketing decisions based on evidence rather than guesswork.
