How to Set Up GA4 Events That Track What Matters

GA4 is built around events, which is a fancy word for actions visitors take on your site. Out of the box it tracks some automatically, but the ones that matter most to your business usually need setting up.

Get this right and your analytics stop being a vanity exercise. Instead of just counting visitors, you see who clicked your phone number, submitted an enquiry, or started a booking, which is the data you can actually act on.

What an event actually is

An event is any interaction worth measuring: a page view, a button click, a form submission, a video play, a file download. GA4 records these so you can understand behaviour rather than just traffic.

Some events are tracked automatically, like page views and scrolling. The valuable ones, the actions tied to your goals, are the ones you decide to capture deliberately.

Which events to set up first

Start with the actions that lead to business: form submissions, clicks on your phone number or email, booking starts, and purchases if you sell online. These are the moments a visitor becomes a potential customer.

Add a few supporting events that show engagement, such as clicks on a key call-to-action button or downloads of a brochure. Resist tracking everything, as a flood of meaningless events just adds noise.

Setting them up reliably

Many events can be configured within GA4 itself or through a tag manager, without touching your site’s code directly. The right method depends on your setup, and a tag manager is usually the cleanest route.

Whatever you use, test each event before relying on it. Trigger the action yourself and confirm it shows up. An event that is set up wrong gives you confident, useless data, which is worse than none.
