How to Track Cliniko Bookings in Google Ads

To track confirmed bookings properly, you need to connect your website, Cliniko, and Google Ads using Google Tag Manager (GTM) and Google Analytics 4 (GA4).

Step 1 – Add Google Tag Manager to Website and Cliniko

Install the same GTM container on:

• Your main website
• Your Cliniko booking pages

This ensures user tracking continues across both platforms.

Step 2 – Set Up GA4 via GTM

Create a GA4 configuration (Google Tag) using your Measurement ID.

Go to your GTM — New Tag – Tag Configuration: Google Analytics: GA4 Configuration (now called “Google Tag”) – Paste the Measurement ID

If Cliniko is embedded on your website using an iframe, you should also configure:

• Cross-domain tracking
• Cookie settings (samesite=none;secure)
• Linker support

or

These settings help track users across domains correctly.

* cookie_flags helps in tracking users across another domain.

* If Cliniko is not embedded then there is no need to use ‘cookie_flags’

Triggering – Page View – All Page Views

Now Save & Publish

Step 3 – Track Booking Confirmation Page

Create a GA4 event for booking confirmation.

Example setup:

• Event name: purchase
• Trigger: Page path contains bookings/confirmation

This ensures only confirmed bookings are tracked as conversions.

To do this:

• GTM – New Tag – Tag Configuration – Google Analytics GA4 Event: –

Name – GA4 Cliniko Purchase

Paste the GA4 Measurement ID

Event Name: purchase

Triggering: Page View – Some Page View:

Page Path            Contains                              bookings/confirmation

                                Name of Trigger – GA4_Cliniko_Booking_Confirmation (or give it any name)

                Save

Step 4 – Track Embedded Cliniko Bookings (Advanced)

If Cliniko is embedded (iframe), you will need to use a listener script.

This script detects when a booking is completed and pushes a custom event into the dataLayer.

Example event:

clinikoBookingCompleted

You can then use this event in GTM to fire a GA4 event.

To do this,

• GTM – New Tag — Name: Listener/ GA4 Listener

Custom HTML — Add the javascript code from cliniko (don’t forget to add script tag at both ends) — Trigger: All page (or just select the iframe page) – Save

===================

<script type=”text/javascript”>

window.addEventListener(“message”, receiveMessage);

function receiveMessage(e) {

if (typeof e.data !== ‘string’) return;

if (e.data.search(‘cliniko-bookings-page:confirmed’) > -1) {

var dataLayer = window.dataLayer || (window.dataLayer = []);

dataLayer.push({

‘event’: ‘clinikoBookingCompleted’

});

}

}

</script>

<script src=”script.js”></script>

===================

Step 5 – Mark Events as Conversions in GA4

In GA4, mark the following events as conversions:

• purchase
• cliniko booking

This allows GA4 to treat them as key actions.

Step 6 – Import Conversions into Google Ads

Once GA4 is tracking bookings:

• Import these conversions into Google Ads
• Optimise campaigns for confirmed bookings

Step 7 – Fix Attribution Issues

To ensure accurate data:

• Remove Cliniko as a referral source
• Configure cross-domain tracking between your site and Cliniko

Otherwise, conversions may incorrectly appear as “Direct” traffic.
