Configure Custom GA4 Events via GTM

The Problem

Out-of-the-box GA4 tracks pageviews, but the actions that actually matter to your business — a form submitted, a button clicked, a key page scrolled through — need to be configured deliberately.

About this problem

GA4 records page views and a few automatic events, but actions such as form submissions, button clicks or scroll depth need to be defined. In Tag Manager this means building a trigger that detects the action (a click, a form submit, a dataLayer push) and a GA4 event tag that sends it with the right name and parameters. Triggers that rely on page structure can break silently when the site changes.

People come looking for this when GA4 shows traffic but nothing about what visitors actually do, or when they need conversion data for reporting. Choosing reliable triggers and verifying each event in GA4 is what separates working tracking from a tag that never fires.

What's Included

• Defining the specific events that matter for your goals
• Setting up triggers and tags in GTM to fire them correctly
• Verifying each event fires and appears correctly in GA4
• Documentation of what was set up and why

What's NOT Included

• Deciding what to track — that's a conversation we'll have, but ongoing strategy is separate
• Server-side conversion tracking for ad platforms (can be scoped separately)
• Historical backfilling of events — they only start from setup

How It Works

1. I agree with you the short list of events that matter and what to name them.
2. I inspect the relevant page elements and, where needed, the form or button behaviour to choose reliable triggers.
3. I create the triggers in GTM, such as click, form submission, element visibility or scroll depth.
4. I create the GA4 event tags with consistent event names and useful parameters.
5. I test each event in GTM preview and in GA4 DebugView to confirm it fires once and arrives correctly.
6. I publish the container and write short documentation of each event and what it measures.

In practice: you buy the service, send over whatever access or details the job needs, I investigate and do the work, and you confirm it's resolved before we call it done.

Frequently Asked Questions

How do I track button clicks in GA4?

With a click trigger in Google Tag Manager and a GA4 event tag that fires on it. I set up and test both.

Can I track form submissions?

Usually yes, using a form trigger or a dataLayer event. The method depends on how the form is built.

Will this show data from before the setup?

No. Events only record from the moment they are published.

Do you decide what I should track?

We agree the list together, but wider tracking strategy is not part of this service.

Does this send conversions to Google Ads or Meta?

Server-side conversion tracking for ad platforms is not included but can be scoped separately.

Do I need GTM already installed?

Yes, a working container is needed. If you do not have one, the GTM installation service applies.
