Add your own Google tags to Colib and measure the traffic on your booking page and your public page in your own Google account, including an event every time a client books an appointment.
Add your tag
Open your Analytics settings. Go to
https://www.colib.io/Settings?show=analytics, or click Settings in the main menu and open the Analytics tab, just under Public Page.Open the Google tags panel. You will find three fields, one per Google product. Fill in only the ones you use. You can leave the others empty.
Paste your identifier and save. Colib checks the format as you type. If an identifier is rejected, compare it with the examples below: a missing prefix is the usual cause.

Which field to fill in
Google Tag Manager – GTM-XXXXXXX
Your container ID, shown at the top of your workspace in Google Tag Manager, next to the container name. Use this field if you prefer to manage all your tags yourself. Colib loads your container, and you decide inside Tag Manager what runs on the page.
Google Analytics – G-XXXXXXXXXX
Your GA4 measurement ID, found in Google Analytics under
- Appointment changes send the same event. When a client edits an existing appointment, they go through the same confirmation screen, so
appointment_bookedis sent again. Keep it in mind when you read your conversion numbers. - The booking widget counts separately. If you embedded the booking widget on your own website, it runs in a frame, and your tags see that visit as separate from the rest of your site.
- Changes take effect immediately. Save the settings, then reload your public page and the tag is live.
What Colib never sends
No client information ever reaches your tags: no name, no email address, no phone number, no date of birth, and nothing from your forms.
That said, your tags remain yours. Analytics collects an approximate location and a visitor cookie on a page where people book healthcare appointments, and the appointment type can be revealing depending on the care you offer. You are the one responsible for those tags, so mention them in your privacy policy and ask for consent where your local rules require it.
Checking that it works
- In Tag Manager, open Preview and load your booking page. Your container appears, and
appointment_bookedshows up in the event list once you complete a test booking. - In Analytics, open Admin › DebugView, or watch the Realtime report while you browse your own page.
- Make a real test booking and cancel it afterwards. It is the only way to see the booking event fire end to end.
Still stuck? Write to us at support@colib.io with your clinic name and the identifier you pasted, and we will check the setup with you.
The form event
When a client submits one of your forms, Colib sends an event called form_submitted to your tags, with three details:
transaction_id – the unique reference of the submission, the same one you see in Forms › Results, so a form is never counted twice.
form_name – the name of the form that was submitted.
establishment_name – the name of your clinic.
