If you manage a website, tracking user behavior, conversions, and marketing performance is crucial. Manually adding tracking codes for tools like Google Analytics, Facebook Pixel, or heatmaps can be tedious. That’s where Google Tag Manager (GTM) comes in—it simplifies tag management without needing to edit your website’s code every time.
In this guide, we’ll walk you through how to set up GTM from scratch, add your first tags, and publish them correctly.
What is Google Tag Manager?
Google Tag Manager is a free tool that allows you to deploy and manage tracking codes (tags) on your website without modifying the source code. Instead of manually inserting JavaScript snippets, you can:
- Add, edit, or disable tags with a few clicks
- Set up triggers to control when tags fire
- Use variables to collect dynamic data
- Test changes before going live
This makes tracking easier, faster, and more efficient.
Step 1: Create a Google Tag Manager Account
- Go to Google Tag Manager.
- Click "Create Account".
Fill in the details:
- Account Name (e.g., your business name)
- Country
- Container Name (usually your website name)
- Target Platform (Select "Web" for websites)
- Click "Create".
Once done, you’ll see the GTM installation code.
Step 2: Install GTM on Your Website
GTM provides two code snippets:
- The
<script>code → Paste this in the<head>section of your website. - The
<noscript>code → Place this right after the opening<body>tag.
Installation Methods:
- WordPress Users: Use plugins like "Insert Headers and Footers" or "Google Tag Manager for WordPress".
- HTML Websites: Edit the
index.htmlfile manually. - Shopify/Other Platforms: Go to Theme Settings > Edit Code and paste the snippets.
Step 3: Understanding GTM Basics (Tags, Triggers, Variables)
Before adding tags, let’s understand the key components:
1. Tags
These are snippets of tracking code (e.g., Google Analytics, Facebook Pixel).
2. Triggers
Rules that determine when a tag fires (e.g., page views, button clicks).
3. Variables
Dynamic values used in tags/triggers (e.g., page URL, click ID).
Step 4: Adding Your First Tag (Google Analytics Example)
Let’s set up a Google Analytics Pageview tag:
- Go to "Tags" > "New" in GTM.
- Click "Tag Configuration" → Choose "Google Analytics: Universal Analytics".
- Enter your GA Tracking ID (e.g.,
UA-XXXXX-Y). - Set Track Type to "Page View".
- Under "Triggering", select "All Pages".
- Name your tag (e.g., "GA - Pageview") and Save.
Step 5: Testing & Publishing Your Container
Before going live, always test:
- Click "Preview" in GTM.
- Open your website in a new tab—GTM’s Debug Console will appear.
- Verify if your tags fire correctly.
- If everything works, click "Submit" to publish.
Recommended Tags to Add Next
- Facebook Pixel (For ad tracking)
- Google Ads Conversion Tracking (For PPC campaigns)
- Scroll Depth Tracking (To see how far users scroll)
- Click Tracking (Monitor button clicks)
Best Practices for GTM Beginners
✅ Use Clear Naming (e.g., "FB Pixel - Purchase Event")
✅ Test Before Publishing (Always use Preview Mode)
✅ Organize with Folders (Group similar tags)
✅ Set Up a Data Layer (For advanced tracking)
✅ Use Version Control (To track changes)
Final Thoughts
Google Tag Manager saves time, reduces errors, and gives you better control over tracking. Start with basic tags (like Google Analytics), test thoroughly, and gradually add more tracking as needed.
