Most companies rely on Google Analytics 4 to make marketing and business decisions.
But there’s a problem.
Just because GA4 is collecting data doesn’t mean the data is correct.
Tracking can break. Settings can change. Tags can stop firing. Someone can make a change in Google Tag Manager. Campaign data can become inconsistent. Problems can sit unnoticed for days or even weeks before someone discovers them.
And most marketers and analysts simply don’t have time to manually check their analytics implementation every week.
That’s one of the reasons we built GA Auditor.
GA Auditor helps you automatically audit and monitor your GA4, Google Tag Manager, and BigQuery implementations.
And you can currently use all of these capabilities for free.
1. GA4 Settings Audit
A GA4 property contains dozens of settings that can affect how your data is collected and reported.
GA Auditor reviews your GA4 configuration and helps identify potential issues or opportunities for improvement.
This is particularly useful when:
- Setting up a new GA4 property
- Taking over an existing implementation
- Reviewing a client’s analytics setup
- Performing periodic analytics health checks
- Verifying that important settings haven’t been overlooked
Instead of manually working through a long GA4 implementation checklist, you can run an audit and quickly see which areas deserve attention.
2. GA4 Data Audits
A technically correct GA4 configuration doesn’t necessarily mean your data is correct.
That’s why GA Auditor also examines the data being collected.
GA4 Data Audits can help identify potential issues with your analytics data and tracking that may not be obvious from simply reviewing your GA4 settings.
Even better, these audits can run automatically every month.
You don’t have to remember to log in and perform another audit.
GA Auditor keeps checking.
This is especially useful because many analytics problems aren’t dramatic enough to immediately get someone’s attention. Data may continue flowing while something underneath has changed.
Automated audits provide another layer of protection.
3. Google Tag Manager Audits
Google Tag Manager containers have a tendency to accumulate clutter over time.
New tags get added.
Old tags remain.
Triggers are created for projects that no longer exist.
Variables are forgotten.
Eventually, you may have a GTM container containing hundreds of tags, triggers, and variables without knowing which ones are still necessary.
GA Auditor analyzes your GTM container to help identify potential configuration issues as well as unused tags, triggers, and variables.
That makes it easier to understand your container and determine where cleanup may be needed.
A cleaner GTM implementation isn’t just easier to manage. It can also make troubleshooting and future development much easier.
4. GA4 Data Issue Alerts
Auditing your analytics once is useful.
Knowing when something changes is even better.
GA Auditor can monitor your GA4 data and alert you when it detects potential issues.
Instead of relying entirely on someone noticing a strange number in a dashboard, GA Auditor can help surface potential problems proactively.
Think about how analytics problems are usually discovered.
Someone notices traffic looks strange.
Then someone investigates.
Then the team realizes the problem may have started several days or weeks earlier.
By that point, some of the affected historical data may be impossible to recover.
Monitoring can help shorten the time between something going wrong and someone knowing about it.
5. GTM Change Alerts
Google Tag Manager becomes more difficult to manage when multiple people have access to the same container.
An analyst makes a change.
A developer publishes something.
An agency updates a tag.
Another team modifies a trigger.
Unless you’re constantly reviewing GTM, you may not know exactly what changed.
GA Auditor’s GTM Change Alerts help you keep track of those changes.
This can be particularly valuable for organizations where several employees, agencies, developers, or consultants work with the same GTM implementation.
You don’t need to constantly check GTM just to find out whether something changed.
GA Auditor can keep an eye on it for you.
6. BigQuery Data Audits
For organizations that want to go beyond the standard GA4 interface, BigQuery opens up much deeper analytics possibilities.
But moving your analysis into BigQuery doesn’t automatically guarantee that the underlying data is correct.
GA Auditor includes BigQuery Data Audits designed to help identify potential issues with your GA4 data in BigQuery.
This gives analysts another way to evaluate the quality of the data they are using for deeper analysis, reporting, and modeling.
The Goal: Analytics That Keeps Checking Itself
The bigger idea behind GA Auditor isn’t simply to create another analytics auditing tool.
It’s to reduce the amount of manual checking required to maintain trustworthy analytics.
Traditionally, analytics auditing looks something like this:
Run an audit → fix problems → wait several months → run another audit.
But analytics implementations don’t remain static between audits.
Websites change.
Marketing campaigns launch.
Developers release code.
GTM containers change.
GA4 configurations evolve.
New tracking gets added.
That’s why we’re moving toward a different model:
Connect your analytics → audit it → continuously monitor it → alert people when something needs attention.
You shouldn’t have to manually check your analytics implementation every week just to know whether something is wrong.
Let the system do the routine checking so you can spend your time actually using the data.
