Google Tag Manager (GTM) has become a must-have tool for tracking and analytics in WordPress. It allows you to add tags for Google Analytics, Ads, pixels, and custom events all without editing code.
But here’s a challenge many WordPress users face: managing multiple GTM IDs.
Explore: How to Sync GTM Tags Across Containers Using TagSyncer
For businesses with different marketing teams, multiple domains, or complex WooCommerce setups, handling more than one GTM container on a single site can get messy. If not managed correctly, it leads to duplicate tracking, missing data, and wasted time.
In this blog, we’ll share best practices for managing multiple GTM IDs on WordPress, and show how TagSyncer makes it simple and error-free.
Why You Might Need Multiple GTM IDs
There are many reasons to run more than one GTM container:
- Marketing & Analytics Separation – One container for analytics, another for ad tracking
- Different Teams – Agencies may need separate containers for clients or campaigns
- Ecommerce Tracking – WooCommerce events in one container, general site tracking in another

Best Practices for Managing Multiple GTM IDs in WordPress

2. Keep Containers Organized
When you use multiple GTM IDs, clearly name tags, triggers, and variables inside each container. For example:
- Analytics – Pageview Tag
- Ads – Conversion Tracking Tag
This avoids confusion when testing.
3. Test Each GTM ID Separately
Always use Preview Mode in Google Tag Manager to make sure each container is firing correctly. Test events like scroll depth, form submissions, and WooCommerce purchases on both IDs.
4. Leverage the DataLayer
The dataLayer is key when managing multiple GTM IDs. It ensures that both containers receive the same events without missing data.
With TagSyncer, scroll depth, form submissions, and WooCommerce events are automatically pushed into the dataLayer ready for both GTM IDs.
5. Monitor Performance Regularly
When running multiple containers, always check:
- Google Analytics reports (to confirm no duplicate hits)
- WooCommerce revenue tracking
- Ad platform conversions (Google Ads, Meta Ads)
This helps you quickly spot if a GTM ID isn’t syncing properly.
