Google Tag Manager Update: What You Need to Know Before April 2025

Google has announced a significant update to Google Tag Manager (GTM) that will automatically load a Google tag before sending events. This change, effective from April 10, 2025, aims to enhance tracking reliability and improve measurement accuracy for advertisers.

If your business utilises Google Ads, Floodlight tags, or relies on conversion tracking, here's what you need to know and how to prepare.

What's Changing?

Currently, GTM containers can send events before loading a Google tag. However, starting April 2025:

GTM containers with Google Ads and Floodlight tags will automatically load a Google tag first before sending events.
This ensures more accurate tracking, reducing data discrepancies.
The update applies automatically, so no manual migration is required.

This adjustment won't disrupt your existing tracking setup but will help businesses capture more reliable conversion data for better decision-making.

Why Does This Matter?

For digital marketers and advertisers, tracking accuracy is crucial. This GTM update offers several benefits:

Increased Measurement Data: With a Google tag loading first, there's a higher likelihood of capturing all conversion events.
More Reliable Google Ads Tracking: Ensures consistent event tracking, improving ad campaign insights.
Seamless Transition: If you take no action, GTM will implement the update automatically on April 10, 2025.

What Should You Do Now?

While this change will apply automatically, it's best practice to prepare ahead of time.

1. Add a Google Tag to Your GTM Container

If you haven't already, ensure a Google tag is added inside Google Tag Manager.
This allows you to preview how the update will impact your tracking setup.

2. Use GTM's Preview Mode

Test your tags, triggers, and events in Preview Mode before April.
Identify potential conflicts and ensure correct tag firing order.

3. Monitor Conversion Tracking Reports

Compare your Google Ads conversion data before and after the change.
If you notice discrepancies, adjust your tag configurations accordingly.

Final Thoughts

This update may seem minor, but it enhances data accuracy and makes tracking more efficient for businesses relying on Google Ads.

By taking proactive steps now, you can ensure a seamless transition and maximise your measurement insights when the update goes live in April.
