GA4 Release Notes Explained: New Tag Diagnostics

Using GA4 can be a learning curve for many of us – but Google is doing its best to make life easier by updating the tool regularly.

However, navigating to Google’s release notes and understanding the impact of these updates isn’t the most intuitive process when we’re swept up in day-to-day business.

That’s why we’re stepping in to explain, in clear terms, what the latest GA4 updates mean – and why you should care about them.

Let’s take a look at the new tag diagnostics.

New Tag Diagnostics

Overview

The new Tag Diagnostics tool in GA4 helps identify issues with your Google tag setup, such as when tags stop sending data or are placed too low on a page, impacting data accuracy and loading speed.

What was happening before?

  • Diagnosing tag issues often required manual checks or waiting for reports to show gaps in data

  • This made it hard to catch problems quickly, like when a tag wasn’t sending data or was positioned poorly

  • These issues can reduce data quality and affect measurement accuracy

What happens now?

  • The updated Tag Diagnostics tool automatically detects key issues

  • If a tag stops sending data, the tool alerts you, helping you catch and fix it quickly

  • Another alert flags tags that are too low on the page, allowing you to adjust placement for faster loading and accurate tracking

  • There’s also a new ‘No recent data’ status that lets you know if a tag hasn’t been active in 48 hours

What does it mean for me?

Faster issue detection and fewer data gaps. With Tag Diagnostics, you can address tagging issues quickly, ensuring accurate, real-time data without disruptions. This helps keep your website measurement reliable and reduces the risk of missing critical insights.
