Publishing changes and managing version control in Google Tag Manager (GTM) is essential for ensuring that your tracking setup is efficient, organized, and error-free. GTM allows you to make updates, test them in a preview mode, and then publish them while maintaining a history of changes. Here’s a detailed guide on how to publish changes and effectively manage version control in GTM.
1. Accessing Google Tag Manager
Step 1: Log In to GTM
- Visit the Google Tag Manager website.
- Log in with your Google account.
- Select the appropriate GTM account and container associated with your website.
2. Making Changes in GTM
Before you publish any changes, you will typically need to create or modify tags, triggers, or variables within your GTM container.
Step 1: Create or Edit Tags, Triggers, and Variables
- In the GTM interface, navigate to the section (Tags, Triggers, or Variables) where you want to make changes.
- Click “New” to create a new item or select an existing item to edit.
- Make the necessary adjustments to your tags, triggers, or variables.
3. Using Preview Mode Before Publishing
Before publishing your changes, it’s crucial to test them using GTM’s preview mode to ensure everything functions as intended.
Step 1: Activate Preview Mode
- Click the “Preview” button in the upper right corner of the GTM interface.
- Enter the URL of your website to start the preview mode.
- A new tab will open with your website and a debug console at the bottom.
Step 2: Test Your Changes
- Navigate through your website to test the changes you’ve made.
- Check the debug console for tag firing status, trigger conditions, and variable values.
- Ensure everything is working correctly.
4. Publishing Changes
Once you’ve tested your changes and confirmed they work as expected, you can proceed to publish them.
Step 1: Submit Your Changes
- In the GTM interface, click the “Submit” button in the upper right corner.
- A dialog box will appear, prompting you to provide a version name and description.
Step 2: Provide a Version Name and Description
- Version Name: Enter a meaningful name for the version (e.g., “GA4 Setup – October 2024”).
- Version Description: Provide a brief description of the changes made (e.g., “Added new e-commerce tracking tags”).
- This documentation will help you and your team understand what changes were made in this version.
Step 3: Publish the Changes
- After entering the version name and description, click the “Publish” button.
- GTM will publish your changes, and the new version will be live on your website.
5. Managing Version Control
GTM provides a robust version control system that allows you to track changes and revert to previous versions if necessary.
Step 1: View Version History
- In the GTM interface, click on the “Versions” tab in the left sidebar.
- You will see a list of all published versions of your container, including the version names, descriptions, and timestamps.
Step 2: Examine Version Details
- Click on any version to view its details, including:
- Tags, triggers, and variables included in that version.
- Changes made compared to the previous version.
- This information helps you understand the evolution of your GTM setup.
Step 3: Revert to a Previous Version
If you encounter issues with the current version or need to revert to a previous setup:
- Go to the “Versions” tab.
- Click on the version you want to revert to.
- Select the “Publish” option to make that version live again.
6. Best Practices for Version Control
To maintain a well-organized GTM setup and facilitate effective version control, consider the following best practices:
- Use Descriptive Version Names: Always use clear and descriptive names for your versions to easily identify the changes made.
- Document Changes: Write detailed descriptions of the changes for each version to provide context for future reference.
- Regularly Review Versions: Periodically review your version history to identify and clean up any unnecessary or outdated tags, triggers, or variables.
- Backup Your Container: Before making significant changes, consider exporting your GTM container as a backup. To do this, go to “Admin” > “Export Container” and save it for future reference.
7. Collaborating with Team Members
If you work in a team, GTM allows multiple users to collaborate effectively:
- User Permissions: Set appropriate permissions for team members based on their roles. You can manage user permissions in the “Admin” section.
- Communicate Changes: Regularly communicate with your team about updates and changes made in GTM, ensuring everyone is on the same page.
