The 5 Most Important Metrics to Track with Google GA4

By Penny M

Google Analytics 4 (GA4) is the latest version of Google Analytics, and it comes with several new and improved features. One of the most significant changes in GA4 is the shift from a session-based data model to an event-driven data model. This change means that every user interaction on a website is recorded as an event, making tracking user behavior and analyzing website performance easier. GA4 is incredibly robust, with lots of metrics marketing professionals can dive into to gain an in-depth understanding of their website users. To keep it simple, we’ve identified the metrics most important to our clients and how to spot them in GA4.

Here are the five most important metrics to track with GA4.

User Acquisition

The user acquisition metric tracks the number of users who visit your website and where they come from. GA4 provides several channels to track user acquisition, including organic search, direct, referral, social media, and paid search.

Analyzing this metric lets you identify which channels drive the most traffic to your website and adjust your marketing strategies accordingly. For example, if your social media campaigns are not driving much traffic, you may need to revise your social media strategy to increase engagement and reach more users.


Engagement is a user-centric metric that tracks how users interact with your website. It includes metrics like session duration, bounce rate, pages per session, and average time on page.

By analyzing engagement metrics, you can better understand how users interact with your website and identify areas for improvement. For example, if your bounce rate is high, it may indicate that users are not finding what they are looking for on your website, and you may need to optimize your content or website design.

Conversion Rate

Conversion rate measures the percentage of users who take a desired action on your website, such as making a purchase, filling out a form, or subscribing to a newsletter. Tracking conversion rates helps you understand how well your website converts visitors into customers.

GA4 allows you to set up events and track them as conversion goals. For example, you can follow when a user completes a purchase or fills out a form. By analyzing conversion rates, you can identify areas where users drop off and optimize your website to improve conversion rates.

GA4 also introduces first-click attribution and a wider variety of attribution models. We're now able to see how people are converting based on the first way they interacted with you and give credit to each interaction that influenced the conversion. In UA, only the last-click source was recorded.


Retention measures the number of users who return to your website after their initial visit. It is an essential metric because it indicates the level of loyalty and engagement of your website's users.

GA4 provides retention metrics that allow you to track how many users return to your website and how often. Comparing the behavior of new vs. returning users can help you fine-tune user journeys.

You can identify ways to improve user engagement and loyalty by analyzing retention metrics, such as offering personalized content or promotions to returning users.


Revenue is a critical metric for e-commerce websites. It tracks the amount of revenue generated from purchases made on your website. GA4 allows website owners to track revenue as an event and provides several e-commerce metrics, including total revenue, average order value, and conversion rate. By analyzing revenue metrics, you can identify the products or services that generate the most revenue and optimize your website to increase sales.

The Bottom Line:

GA4 is a powerful tool for tracking website performance and user behavior. By tracking these five key metrics, user acquisition, engagement, conversion rate, retention, and revenue, website owners can get a comprehensive view of their website's performance and make data-driven decisions to improve it. With GA4's event-driven data model, website owners can track user behavior more accurately and understand how users interact with their websites over time.
