Explore these important Google Analytics 4 metrics and align them with your SEO campaigns today.
Picture this—your brand’s website is growing with traffic after a new campaign launch, but conversions aren’t matching up to expectations.
Curious, you open Google Analytics 4 (GA4).
But as you sift through the endless dashboards and metrics, you feel overwhelmed.
What do these numbers really mean for your brand’s performance?
Are you looking at the right data points?
GA4 is a brilliant tool for tracking and optimizing your digital presence, but its rich complexity can feel daunting, especially if you don’t know which metrics to focus on.
For digital marketers and SEO specialists, understanding Google Analytics 4 metrics can be the difference between a successful strategy and wasted opportunities.
In this guide, I’ll walk you through the most important GA4 metrics—what they mean, why they matter, and how you can act on them.
Whether you’re optimizing website traffic or analyzing campaign ROI, these insights will help you use GA4 effectively.
What Makes GA4 Different from Universal Analytics?
Before we jump into metrics, it’s important to understand how GA4 differs from its predecessor, Universal Analytics (UA).
Think of UA as the old-school teacher—reliable, but limited in foresight.
On the other hand, GA4 is like a tech-savvy professor, offering advanced behavioral insights, better cross-platform tracking, and predictive analytics.
The biggest game-changer is the event-based structure in GA4.
Instead of tracking sessions or page views as isolated actions, GA4 sees each user interaction (a button click, video play, or page scroll) as a unique event.
This shift helps marketers better understand user behavior and intent.
Now that you’ve adjusted your glasses, ready to focus on the data, here are the key GA4 metrics you need to know.
15 Key Google Analytics 4 Metrics to Track
GA4 organizes its metrics into events-based tracking, which focuses on user interactions rather than static page views, allowing for more nuanced insights.
Below are 15 key Google Analytics 4 metrics every digital marketer needs to monitor:
1. Active Users
Active users in GA4 reflect the users actively engaging with your site or app.
This metric excludes people accidentally landing on your site and leaving immediately.
Imagine running a coffee shop. It’s not enough to know how many people walked by your storefront; you’re interested in the ones who walked in, browsed the menu, or ordered a latte.
That’s what “active users” are for your website—a way to measure qualified traffic.
Why It Matters:
Active users tell you about engagement.
A spike could mean a successful social campaign, while a drop signals efforts to grab relevant attention might need revisiting.
Pro Tip:
Compare this with sessions to see if users are browsing multiple pages or bouncing after the first one.
If bounce rates are high, focus on making landing pages more relevant or invest in better CTAs.
2. Engagement Rate – Quality Over Quantity
Engagement rate in GA4 measures how often users interact meaningfully with your site.
This could include spending a certain amount of time, scrolling through a page, or completing key actions.
Remember your last movie date?
If they checked their phone a few minutes in, they weren’t engaged.
Engagement rate ensures your audience isn’t just passively scrolling—they’re hooked.
Why It Matters:
A high engagement rate directly correlates to user interest.
For SEO specialists, it signals that your content aligns with search intent.
Pro Tip:
Use segmentation to check engagement rates across new vs. returning visitors.
Are returning visitors more engaged?
If so, nurture that loyalty with tailored email campaigns.
3. Event Count – Decoding User Behavior
GA4’s event-based model shines when you understand the importance of event counts.
Whether it’s a button click, video play, or download, event counts quantify user interactions.
Imagine your site as a store—every aisle visit, cashier interaction, and receipt scan is an event.
GA4 gleans insights from these micro-interactions.
Why It Matters:
Knowing which events are most common can help prioritize optimizations.
If video views are high but purchases are low, you may need to rework CTAs or simplify the checkout process.
Pro Tip:
Track micro-conversions by assigning values to events like “Add to Cart” or “Sign Up for Newsletter.”
This allows a clear assessment of the steps leading to a conversion.
4. Conversion Rate – Measuring Success
Success in digital marketing always circles back to conversions.
GA4 lets you track custom conversions, whether that’s a purchase, form fill, or email signup.
Think of your marketing strategy as planting an apple tree.
Conversions are the fruits—the result of time, effort, and nurturing the right soil (audience).
Why It Matters:
Conversion rates are critical for tying campaigns to ROI.
They measure the effectiveness of not just your website but every traffic source redirected to it.
Pro Tip:
Redefine conversions in GA4 to align with your KPIs.
For example, instead of just “Purchases,” track micro-conversions like “Social Media Signups.”

5. User Lifetime Value (LTV) – Long-Term Impact
Lifetime Value determines how valuable a user is to your business over time.
Instead of looking at isolated purchases, GA4 lets you track recurring visits, repeat purchases, or subscription renewals.
LTV is like investing in a garden—one-time expenses may not seem profitable, but the long-term harvest defines success.
Why It Matters:
Long-term metrics like LTV help in prioritizing efforts.
Is it more valuable to nurture existing users or acquire new ones?
LTV can provide the answer.
Pro Tip:
Combine LTV analysis with customer segmentation to pinpoint which cohorts generate the highest revenue.
6. Acquisition Data – Where Do Users Come From?
GA4’s acquisition metrics show you where your traffic is generated from.
Organic search, paid ads, social media, email—all sources have distinct impacts on your overall performance.
Imagine throwing a party and inviting people via flyers, texts, and Instagram posts.
Acquisition data is your guest list—it tells you where folks heard about your party.
Why It Matters:
Knowing which channel drives the most high-value users can save your marketing budget from being spread too thin.
Pro Tip:
Use GA4’s “First User Medium” dimension. If organic search drives the majority of loyal users, double down with targeted SEO campaigns.
7. Predictive Metrics – The Crystal Ball
One of GA4’s most exciting features is its predictive metrics.
For instance, metrics like “Purchase Probability” estimate how likely users are to convert based on past behaviors.
While crystal balls don’t exist, GA4’s predictions come close.
Why It Matters:
Predictive analytics helps forecast trends and tweak your strategy proactively.
Pro Tip:
Use predictive metrics to create remarketing audiences.
Target users with high “Churn Probability” to reduce attrition with personalized offers.
8. Average Engagement Time per Session – Quality Over Quantity
How long are people spending on your site? More importantly, are those minutes meaningful?
GA4’s “Average Engagement Time per Session” measures the average duration of sessions that meet pre-defined engagement thresholds.
I once worked with a mobile app marketer who noticed users spent 7–10 minutes on their content dashboards.
But deeper analysis revealed an issue—the time wasn’t spent exploring features but understanding a confusing layout.
Without this metric, his team wouldn’t have detected the root cause of high churn rates.
Diagnostic Use:
Track this metric alongside heatmaps or session recordings.
They provide context to whether a high session time is due to convenience—or confusion.

9. User Retention Rate – Building Long-Term Relationships
“We got great traffic this month,” said Andrea, a travel marketer.
“But why aren’t they coming back?”
This reflection led Andrea to track User Retention in GA4.
Moreover, it measures the percentage of first-time users returning to the website after their initial session.
Retention isn’t just about securing a momentary “yes.”
It’s about ensuring customers find reasons to re-engage with your content, offers, or services in the future.
Reflective Question:
Ask yourself, “What am I doing to provide continuous value?”
Define incentives—exclusive content, loyalty points, or timely offers—to improve retention.
10. Sessions Per User
This metric measures the average number of sessions (or visits) a user initiates during a specific date range.
Why it’s important:
A high number of sessions per user suggests great engagement with your site.
It could indicate that users find your content appealing or see value in returning.
For example, an e-commerce site with 4-5 sessions per user might mean that customers are comparing products before deciding.
Pro Tip:
Compare this metric with bounce rates.
If sessions are high but bounce rates are too high, users might be revisiting but not finding what they need.
11. Session Conversion Rate
This Google Analytics 4 metric is the proportion of sessions that result in a desired action (like a purchase, form submission, or app download).
Why it’s important:
If your site receives hundreds of visits but only 2-3 conversions, there might be roadblocks within your customer flow.
Session Conversion Rate highlights the effectiveness of your site or landing pages in driving results.
Example Use Case:
Imagine you’ve just launched a digital ad campaign targeting newsletter sign-ups.
Tracking the session conversion rate will confirm whether those clicks are actually bringing value or if something needs adjustment in your call to action.
12. Users vs. Returning Users
GA4 distinguishes between new and returning users to provide a clear picture of overall traffic.
Why it’s important:
An increase in returning users demonstrates loyalty and interest, while a drop could signal dissatisfaction or a fading relevance.
Conversely, tracking new users shows whether your campaigns are successfully targeting fresh audiences.
Tip for Marketers:
Analyze what’s driving newcomers versus keeping loyal users.
This could mean creating exclusive content for regular visitors while maintaining high-performing traffic drivers for first-timers.
13. Views Per User
This measures how many pages or screens a user interacts with during a session.
Why it’s important:
If users engage deeply with your content, they’re more likely to act on your call-to-action (like buying a product).
On the flip side, if this metric is low, users could be frustrated with navigation or content relevance.
Story Insight:
A client once shared they struggled to boost online magazine subscriptions.
Tracking Views Per User revealed which articles consistently led to subscriptions, allowing them to create similar content that converted much faster.

14. Entrances and Exits
GA4 makes it easy to see where users are entering and leaving your site.
Why it’s important:
Tracking entrances can highlight high-performing landing pages, while exits identify where you’re losing traffic.
For an SEO professional, this metric is crucial for deciding which pages to optimize next.
Real-life Scenario:
An e-commerce blog post titled “Top 10 Winter Jackets” might drive entrances but also result in a high exit rate if there’s no clear link to the product pages.
Quick Fix:
Add a strong internal link or promotion banner at the end of the post to keep users on your site longer.
15. Engaged Sessions and Engagement Rate
Engaged Sessions are defined as interactions where users either spent over 10 seconds on your site, triggered an event, or visited multiple pages.
The Engagement Rate shows what percentage of sessions qualify as “engaged.”
Why it’s important:
This combination captures real interest better than generic metrics like bounce rates.
High engagement rates can signal that your audience finds your content useful, which directly correlates to stronger SEO rankings and brand loyalty.
How to Use These Google Analytics 4 Metrics to Take Action
Understanding these GA4 metrics is half the battle—the other half lies in execution.
Below are actionable ways to apply what you’ve learned:
- Use Session Conversion Rate to analyze the effectiveness of ad campaigns and tweak underperforming strategies.
- Pair Entrances and Exits to fix abandoned pages.
- Rely on Returning Users data to design loyalty programs or exclusive offers.
- Improve content navigation for low Views Per User performance.
By regularly evaluating these numbers, you’ll create a comprehensive roadmap that not only optimizes your campaigns but also transforms your users’ experience.

Why is GA4 Important in Modern SEO and Marketing?
GA4 reflects how SEO and digital marketing are evolving.
It’s no longer only about traffic volume; it’s about understanding behaviors, optimizing engagement, and predicting future actions.
Using advanced metrics from GA4 also sets you apart from competitors who may still rely on outdated methods of analyzing performance.
For example, while one e-commerce site may continue pouring resources into “increase users on the page,” you’ll instead focus on actionable insights like session quality and high-engagement pages—a smarter, revenue-driven approach.
