GA4 Audit: 16 Questions to ensure your account is set up correctly

Your Google Analytics 4 is running, and you can see the data flowing, but you are not sure if your setup is efficient enough.

Here you can find a step-by-step GA4 audit guide. It is divided into blocks that represent a logical sequence of steps.

This way, you can quickly check your Analytics setup and improve it if needed.

An overview of what we’ll cover:

So let’s dive in!

How to implement the GA4 Tag?

  1. What is your implementation architecture?

The most fundamental step is to understand how your Google Analytics was implemented.

Since there are several implementation options (in the code directly, via GTM, CMS integration, via plugin), you should have a clear vision of your implementation architecture. 

Why is it necessary? Well, if you want to set up conversion tracking or configure a consent mode, you would need to stick to one implementation option to have clean tracking. 

If you prefer code implementation, everything should be configured in the source code directly. In case you use Google Tag Manager, it is recommended to set up all your Tags via GTM. 

In this way, you would ensure neat organization of your Tags as well as efficient tracking.

What are your GA4 property settings? 

  1. Have you selected the correct reporting time zone?

Go to Admin in the bottom left corner and then navigate to Property Settings.

Accessing Reporting Time Zone settings in your property

It is important to choose the correct time zone since it has a direct impact on your reports. The country you’ve selected here will be used as the day boundary in your reports. 

This means that the day is calculated based on the time of the chosen country even if users visiting your page are from elsewhere. 

Therefore, if you are based in Europe, and you are running your business in the US, it would make sense to choose your business location as a time zone.

  1. Have you activated Google signals?

Here you should check whether Google signals are activated for your GA4 property.

In this way, you will be able to collect cross-device data for signed-in users and also set up remarketing across devices.

This will ensure accurate tracking as well as demographic data shown in your reports.

To be able to configure this, go to Data Settings Data Collection, and click Get Started.

Navigating to Data Collection settings

Click Continue to activate your Google Signals.

Enabling new Analytics features for advertising

Please note that it is extremely important to review the data protection policy and privacy regulations of your country before activating the feature.

Activating your Google Signals
  1. Have you set up the data retention period?

When you create a GA4 property, your data retention is set to 2 months by default. 

What does this mean? You will not be able to dive into exploration reports after 2 months, but you will still have access to the aggregated reports.

Choosing the data retention period

This is why it is recommended to change this retention period to 14 months (unless you have privacy reasons for keeping it at 2 months).

  1. Have you selected the reporting attribution model which would be the most suitable for your business needs?

An attribution model determines how much credit should go to a conversion. 

Your users are clicking multiple ads before buying your product or submitting a form on your webpage. 

How can we identify which ad encouraged them to convert?

Selecting the reporting attribution model

 Until now, it was always a last-clicked ad by default, but other clicked ads were not taken into consideration. So now you have this excellent GA4 feature enabling you to choose the attribution model which will reflect the users’ path to a conversion.

  1. Have you enabled enhanced measurement? 

GA4 offers an amazing feature that allows you to track interactions without adding any additional code to your webpage. 

The only thing you have to do is to enable it in your GA4 settings. 

As a result, multiple events will be tracked automatically bringing more data to your reports.

You can enable it by sliding the switch for Enhanced measurement ON.

  1. How is your account managed?

If you are working on a big project, you should arrange your GA4 access. 

There are different levels of user permissions, and each can be assigned for a specific role with its respective restrictions. 

Overview of different roles in GA4 account settings

Some basic settings have now been checked, so now it’s time to move to the data flow arrangement.

How to organize your GA4’s data flow

  1. Have you set up filters?

It is important to ask yourself if you have any data to be filtered.

Go to Data SettingsData Filters.

Finding data filters in your GA4 property

At present, only 2 filter types are available in GA4: internal traffic and developer traffic.

They are not as flexible as filters in Universal Analytics, yet can be useful.

Two types of filters available in GA4

It is recommended to exclude internal traffic, as it might have a considerable impact on your reporting, especially if there are many people involved in the project.

  1.  Have you identified unwanted referrals?

Apart from filters, it is important to configure your unwanted referrals. 

One of the most common use cases could be a third-party payment method for your e-commerce store. 

Let’s say your web page visitors can pay via PayPal. Thus, they will get redirected to that web page and then return to your store.

In this case, we don’t want to identify traffic as a referral and need to do some additional setup to ensure clean reports.

Go to Data StreamsMore Tagging Settings.

Navigating to More Tagging Settings in your data stream details

Here you should select List unwanted referrals

Listing unwanted referrals under Tag Configuration

In this field, you can provide all the necessary conditions for your traffic.

  1. Have you set up any custom dimensions and metrics?

These are powerful features that can help you track additional data about your users.

While conducting a health check, it is important to understand if you are using any custom dimensions and if they are set up correctly.

Overview of the Custom Definitions section

You should also check if your custom metrics are registered correctly in the reports. 

Remember that one can create up to 50 event-scoped custom dimensions and 50 custom metrics per property as well as 25 uniquely named, user-scoped, custom dimensions per property, according to official Google documentation.

  1. Have you chosen your Default Reporting Identity?

Another issue is – how would you like to identify your users? 

There are 2 options available, namely By User ID and device and By device only. 

This setting determines how Analytics associates events with your users, and you should definitely check it, as it has a direct impact on your reports. 

To be able to set this up, go to Admin and then select Reporting Identity.

  1.  Have you verified your conversion tracking?

One of the crucial steps is to verify if your conversion tracking is set up properly. 

You should have a clear outline of the conversions you have implemented. 

Do you have macro-conversions as well as micro-conversions leading up to the macro ones? Are your conversions being recorded correctly?

  1.  Have you implemented Ecommerce Tracking?

If you are running an online store, eCommerce tracking implementation is a must. 

It is important to check if your transactions are recorded and if correct values are sent to your Analytics properly.

Do you have any product linkings?

  1. Are you exporting your data to BigQuery? 

It is beneficial to set up the BigQuery integration since you can keep your data beyond the 14-months retention period. 

This feature gives you much flexibility, as you can store and manipulate your data according to your business needs.

Navigation path: Admin → Product Links → BigQuery Links

  1. Have you linked your GA4 to Google Ads? 

This is a fundamental step if you want to import data from GA4 to your Ads account. You should check if your accounts are linked correctly in order to avoid any data import issues.

Navigation path: Admin → Product Links → Google Ads Links

Connecting GA4 to Google Ads
  1. Are you using Search Console integration?

This integration enables you to analyze organic searches that bring users to your webpage.

You should check if your accounts are connected in the correct way. 

This linking lets you see which queries result in clicks and what engages your users to convert.

Of course, there are other product integrations available, but this is just a quick health check containing some basic audit aspects.

Summary

We have covered the basic steps for your quick Analytics health check. These 16 questions should help you configure your GA4 property correctly, especially if you have a freshly implemented GA4 and are not sure what the next steps should be.
