Install & Configure Google Tag Manager (GTM)

The Problem

Without GTM, every new tracking pixel or analytics tag means editing site code directly — with GTM installed properly, you (or I) can add and change tags safely through one dashboard.

About this problem

Google Tag Manager is a container loaded once on every page, which then loads and controls other tags (analytics, pixels, conversion scripts) from a web interface. This avoids editing site code for every change. If the container snippet is missing from some templates, or old tracking scripts are left in place alongside it, tags fire twice or not at all.

People look for this when marketing tools start piling up as hardcoded scripts, or when an agency asks for a GTM container to be installed. A correct base installation, tested in preview mode, is the foundation everything else builds on.

What's Included

• Creating the GTM container and installing it correctly across every page
• Verifying the container fires using GTM's own preview/debug mode
• Migrating any existing hardcoded tracking scripts into GTM where sensible
• A quick walkthrough of how to use it going forward

What's NOT Included

• Setting up every individual tag you might ever want (quoted per tag/event as needed)
• Server-side GTM setup, unless specifically requested
• Ongoing tag management

How It Works

1. I create the GTM container for your domain, or use the one you already have.
2. I add the two container snippets to the site so that they load on every page and template.
3. I use GTM's preview and debug mode to confirm the container loads and fires on real pages.
4. I identify existing hardcoded tracking scripts and move them into GTM where this is sensible.
5. I check for duplicated tags to prevent double-counted data.
6. I publish the container and show you how to use it for future changes.

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

What is Google Tag Manager used for?

It lets you add and manage tracking tags, such as analytics and ad pixels, from one dashboard without editing site code each time.

How do I know GTM is installed correctly?

Its preview mode shows whether the container loads and which tags fire on each page. I verify this on the site.

Will you move my existing tracking into GTM?

Where it makes sense, yes, for scripts that are already on your site. I avoid moving anything that would risk breaking tracking.

Do you set up all the tags I will need?

No. Each individual tag or event is scoped separately.

Do you do server-side GTM?

Not unless specifically requested, as it is a larger piece of work.

Does this slow my site down?

GTM itself is light, but the tags loaded through it can add weight. I only load what is needed.
