Using Google Tag Manager Effectively
To fully leverage Google Tag Manager, it’s essential to understand how to create and manage tags, triggers, and variables.
Tags
Tags are snippets of code that collect data and send it to third-party services.
- Common Tags: Google Analytics, Google Ads Conversion Tracking, Facebook Pixel, LinkedIn Insights, and custom HTML tags.
- Creating Tags: Follow the steps above to configure each tag, ensuring you enter the correct details and set appropriate triggers.
Triggers
Triggers determine when and where tags are executed on your website.
- Types of Triggers: Page View, Click, Form Submission, Scroll Depth, Custom Event, etc.
- Creating Triggers: In GTM, go to “Triggers” and click “New.” Choose the type of trigger and configure the conditions under which it should fire.
Variables
Variables store values that GTM uses to execute tags and triggers.
- Types of Variables: Built-in variables (e.g., Page URL, Click Text), User-defined variables (e.g., JavaScript variables, Data Layer variables).
- Creating Variables: Go to “Variables” in GTM and click “New.” Choose the type of variable and configure its settings.
Advanced Google Tag Manager Usage
For more advanced tracking and data collection, you can utilize custom tags, data layer, and GTM templates.
Custom HTML Tags
Custom HTML tags allow you to implement custom tracking codes that aren’t covered by standard tag templates.
- Create a Custom HTML Tag: In the “Tag Configuration” section, choose “Custom HTML.”
- Enter Your Code: Paste your custom code into the HTML field.
- Set a Trigger: Define when the custom tag should fire by adding an appropriate trigger.
Data Layer
The data layer is a JavaScript object that GTM uses to pass information between your website and GTM. It helps in tracking complex user interactions and sending this data to third-party tools.
- Setting Up Data Layer: Add a data layer script to your website’s HTML.
<script>
window.dataLayer = window.dataLayer || [];
dataLayer.push({
'event': 'customEvent',
'customVar': 'value'
});
</script>
- Using Data Layer Variables: In GTM, create a new variable and choose “Data Layer Variable” as the type. Enter the variable name used in the data layer script.
GTM Templates
GTM templates are pre-configured tag, trigger, and variable setups that simplify the implementation process.
- Browse Templates: In GTM, go to the “Templates” section.
- Add a Community Template: Click “Search Gallery” to find and add templates created by the community.
- Custom Templates: Create your own custom templates if needed, using the “Template Editor” in GTM.
Debugging and Publishing
Before publishing changes in GTM, it’s crucial to test and debug your tags to ensure they work correctly.
Preview Mode
- Enable Preview Mode: In GTM, click the “Preview” button to enter preview mode.
- Test Your Tags: Open your website in a new tab. The GTM debug console will appear at the bottom, showing which tags are firing and any errors.
