GA4 Alerts: All-in-one Guide 2024

If you want to receive notifications about unusual changes in your business metrics, you can set up GA4 alerts to send you emails when unexpected events occur. For instance, you can create alerts in GA4 to inform you if your website traffic drops to a specific level. This feature makes GA4 a powerful tool for enhancing your analytics. Hence, we highly recommend that you configure them. Here is how you can set up custom alerts in Google Analytics 4.

What are custom alerts in Google Analytics?

Custom alerts in Google Analytics are notifications you can set up to keep track of specific metrics or conditions related to your website or app’s performance. These alerts help you stay informed about important changes and act accordingly.

For example, let’s say you have an online store and want to be alerted if your daily revenue drops below a certain amount. You can create an alert in Google Analytics 4 to notify you when the revenue falls below the specified threshold.

Another example could be monitoring website traffic. If you have a blog and want to track the number of daily visitors, you can create a custom alert to notify you if the traffic exceeds a specific threshold, such as 1,000 visitors per day. This alert can help you identify when your content performs exceptionally well and may require further promotion or optimization.

You can tailor GA4 alerts to various metrics and conditions based on your business goals. Whether it’s monitoring bounce rates, conversions, or any other KPIs, you can set up alerts to receive notifications when certain thresholds or conditions are met.

You can stay proactive in managing your website’s performance by utilizing custom alerts. Instead of manually checking metrics regularly, notifications will alert you when significant changes occur, enabling you to take immediate action and make data-driven decisions to optimize your website’s success.

What are the differences between custom alerts in Universal Analytics and Google Analytics 4?

There are several differences between custom alerts in Universal Analytics and Google Analytics 4, and we will discuss the key ones in this section. 

In the previous version of Google Analytics (Universal Analytics), it used to be called Custom Alerts, but in the recent version, GA4, it is called Custom Insights.

In Universal Analytics, you can set up your notifications to notify you via email or text. However, in GA4, you can only be notified via email.

Unlike Universal Analytics alerts, Google Analytics 4 alerts also involve predictive analytics. This means that GA4 has two types of alerts: suggested insights, which are generated by GA4 using machine learning, and custom insights you can create on your own, similar to UA’s custom alerts.

Additionally, in GA4, the alerts are more advanced and can provide more detailed and accurate insights into your website or app performance, allowing you to make more informed decisions based on the data provided. 

Overall, the shift from Custom Alerts in Universal Analytics to Custom Insights in GA4 represents a move towards more sophisticated and data-driven alerting capabilities in Google Analytics.

How to set up GA4 alerts

There are two types of alerts in GA4: Suggested Insights and Custom Insights. Let’s look at how to set them up in GA4.

Suggested insights

Suggested insights are automated insights that GA4 creates automatically using machine learning based on unusual changes or emerging trends in your data, which you can view on the Insights dashboard in GA4.

To set up a suggested insight, go to your GA4 home page, scroll down to the “Insights & Recommendations” section, and click “View all insights.” Then, click the create button, and a new window will show the suggested custom insights lists. Click the Review and Create button beside each insight to review the setup if it suits your needs. Make sure to tick the one you desire and click the “Create selected” button to create it.

5 Best Practices to improve your GA4 alerts

There are various opinions on how to structure analytics alerts, but the following four rules are essential:

  1. Send alerts to individuals who are familiar with them and know how to take action upon receiving them. It is pointless to notify someone who cannot address the metric change.
  1. Name alerts in a way that is easily understandable to everyone without further discussion. For instance, if a daily metric change triggers the alert, clearly label it as such. If the alert pertains to a decrease in revenue, specify it as “Revenue decreased by 30% yesterday.” Clarity accelerates the response time and ensures that alerts are addressed.
  1. Determine actions to take when you or your team members receive an alert. Should they investigate further within GA4 to understand the issue and then formulate a plan for the team? Addressing these questions beforehand will help streamline the response process when alerts are triggered.
  1. Avoid creating custom alerts just for the sake of it. Set up alerts in GA4 for Objectives and Key Results (OKRs) or Key Performance Indicators (KPIs) and regularly review them to eliminate outdated alerts that are no longer relevant.
  1. Establish appropriate thresholds for your alerts. If you frequently receive alerts you eventually ignore, it indicates that the threshold set for custom alerts is too low. Adjust the threshold in GA4 to receive notifications only when significant events occur.

Real use-cases for custom alerts  

Now, let’s delve into some real-world use cases of GA4 alerts to understand how businesses can leverage this feature to monitor and optimize their online performance effectively.

E-commerce Website

Scenario: An e-commerce website wants to track the conversion rate of its checkout process and sets up custom alerts to receive notifications if the conversion rate drops below a certain threshold.

Condition: Send an alert if the daily revenue decreases by more than 20% compared to the previous day. 

Value: Daily revenue on Monday is $10,000; on Tuesday, it drops to $7,000. An alert is triggered because the revenue decreased by 30%.

Lead generation website

Scenario: A lead generation website wants to track the number of form submissions and sets up custom alerts to receive notifications if there is a sudden increase in form submissions.

Condition: Send an alert if the number of form submissions increases by more than 50% compared to the previous day. 

Value: On Monday, there were 100 form submissions, and on Tuesday, there were 175 form submissions. An alert is triggered because the number of form submissions increased by 75%.

GA4 alerts limitations

While you can create custom alerts in Google Analytics 4 for various scenarios, there are some limitations to be aware of. Here are a few key points to consider:

  • Google Analytics 4 allows you to create segments for custom alerts, but there is a limit on the number of dimensions you can use. For example, you may not be able to select users who performed a specific event directly, but you can create an audience first and then use that audience as a segment in your alerts.
  • There is a limit of 50 custom insights (alerts) per property in GA4.

Despite these limitations, workarounds are available to create important alerts and insights for your business. You can use audiences to specify custom parameters or events to achieve the desired results. Additionally, following best practices for organizing custom alerts in Google Analytics 4 can help you maximize this feature.
