Home / Tracking setup / Google Tag Manager setup
Google Tag Manager keeps your tracking code in one place. You can add, test and remove tags without editing your website each time. For healthcare, it is also the best place to control what loads and where.
Tag Manager in four words
The partsWhat it does
Google describes Tag Manager as a tag management system that lets you set up and manage tags on your site without changing your website’s code. Once two code snippets are on your pages, you make most changes in the Tag Manager web interface. Tags are the pieces of code, triggers decide when they run, and variables are reusable values.
In short
What I set up
One container for your site, with two snippets added to your pages once.
Google Analytics, Google Ads, Meta Pixel and TikTok Pixel tags, each with the right trigger.
Phone taps, form sends and booking confirmations, with page rules so tags do not load on private pages.
Tags respect cookie choices using consent mode where it applies.
Preview mode shows which tags fire on each action, before anything is published.
Clear tag names, version notes and access in your name.
What gets counted
Fires when someone taps a phone link.
Fires when a form is submitted successfully.
Fires on the thank-you step, with no patient details.
Keep tags off logged-in and patient pages.
Hold tags until consent where it is needed.
Every change is named and dated.
How setup works
I find tags already on your site and remove duplicates that would count twice.
We list the tags, triggers and the pages each may load on.
I set up the container, tags, triggers and consent settings.
I test in Preview mode, publish, and write version notes.
Health privacy first
Care point 1
Tag Manager lets you stop tags on pages that show patient information. Google says not to place Analytics tags on logged-in pages, and TikTok says not to use its pixel where you may share personal health information.
Care point 2
Consent mode tells Google tags what cookie permissions a visitor gave. It does not provide a consent banner, so you still need your own. Google tags can run in a basic or an advanced mode.
Care point 3
Anyone who can publish a container can add code to your website. Keep access to named people, and remove it when work ends.
Checked in November 2026. This is a plain-English summary, not legal advice. Platform rules and court cases change, so check them with your adviser.

Testing
Preview mode lets us see every tag before it goes live. Google has a guide to previewing and debugging containers.

Common questions
It is a tag management system that lets you set up and manage tags on your site without changing your website’s code each time.
No, but it makes tracking easier to manage, test and change. Without it, each change means editing your website code.
No. It is a tool for managing tags. What you send and where tags load still decide your privacy risk.
Yes. I can review it, remove what you do not need and tidy it up.
It runs some tags on a server instead of in the browser. It can give more control but needs more setup. Ask me if it could fit your practice.
