GA4 gives us four different ways to count users. If you’re wondering why we need that many, the answer comes down to a fundamental shift in how Google thinks about analytics: not all visits are created equal, nor are they all worth the same.
Someone who lands on your website and leaves in three seconds shouldn’t carry the same weight as someone who explores multiple pages or converts. Each of GA4’s user metrics – “Total users”, “Active users”, “New users”, and “Returning users” – answers a different question about your audience: who reached your site, who engaged with it, who’s new, and who’s coming back.
Understanding which metric to use when is the difference between accurate insights and misleading conclusions. We’ll help you with that today.
Why GA4 changed how it counts users
In Universal Analytics (UA), the primary metric was “Total users”: basically, everyone who landed on your website. Now, in GA4, quality engagement is prioritized over raw traffic counts: the default user metric you see in most reports is “Active users”, which focuses on people who actually engaged with your content.
This shift was made to reflect a simple truth: someone who visits your website for two seconds tells you less about your marketing performance than someone who sticks around, explores pages, or converts.
GA4 also improved cross-device tracking compared to UA, which means these user counts are more accurate when someone visits from multiple devices. GA4 uses Enhanced Measurement and User-ID (when implemented) to recognize the same person across devices, reducing duplicate user counts.
A) Total users: your complete reach
“Total users” represents everyone who triggered any event on your website during your selected date range (even events sent via Measurement Protocol without an active session). This includes the person who landed on your homepage and immediately bounced, the person who spent 30 minutes reading your content, and everyone in between.
What counts as a “Total user”:
- Anyone whose browser loaded your GA4 tracking code.
- Visitors who stayed for just a second.
- Visitors who engaged deeply with multiple pages.
- Both new and returning visitors.
Where to find “Total users”:
This metric isn’t the default in most GA4 reports. You’ll find it in Reports > Engagement > Events, or you can customize any standard report by clicking the pencil icon and adding the “Total users” metric manually. You can also use Explorations (free form reports) to combine and compare these metrics side by side.
B) Active users: GA4’s primary metric
When you see “Users” in most GA4 reports, you’re actually looking at “Active users”, not “Total users”. A user counts as active when they meet any of these conditions:
- Have an engaged session (lasted 10+ seconds, or had 2+ page views, or triggered a key event).
- Are visiting for the first time (new users are automatically considered active).
This metric shows you who actually engaged with your content rather than just who briefly visited. If you’re running ads to drive qualified traffic, “Active users” reveals whether those clicks translate to genuine interest.
Behind the scenes, GA4 tracks “Active users” by checking for the engagement_time_msec parameter (with a value greater than zero) in any event.
Note that “Active users” will always be equal to or lower than “Total users”. The gap between these two numbers reveals how many visitors bounced without engaging – valuable information for evaluating your landing pages and user experience.
Keep in mind: the 10-second threshold isn’t set in stone. You can adjust it up to 60 seconds by going to Admin > Data streams > [select stream] > Configure tag settings > Adjust session timeout.
Where to find “Active users”:
Since this is GA4’s default, it’s basically everywhere. Look for the “Users” column in Reports > Acquisition > Traffic acquisition, or Reports > Engagement > Landing page. The Reports snapshot (your overview) also shows “Active users” by default.
C) New users: measuring acquisition
This metric counts people visiting your website for the first time within your selected date range. GA4 identifies these visitors when it collects the first_visit event (for websites) or first_open event (for mobile apps).
What makes “New users” useful:
- Tracks the effectiveness of acquisition campaigns.
- Shows whether your reach is expanding beyond your existing audience.
- Helps you evaluate new traffic sources.
Where to find “New users”:
You’ll find them prominently displayed in Reports > Acquisition > Acquisition overview, or in Reports > Acquisition > User acquisition, which breaks down where your new visitors come from.
D) Returning users: measuring loyalty
This metric includes anyone who has visited your website at least once before, regardless of whether their previous sessions were engaged.
This metric helps you understand retention and audience loyalty. A healthy balance between new and returning users suggests you’re both growing your audience and keeping them interested.
Where to find “Returning users”:
This metric isn’t shown by default in most standard reports. To see it, customize any report (or use Explorations) by adding “Returning users” to the “Metrics” section.
Why the math doesn’t add up
Here’s the confusing part about this set of metrics: “New users” plus “Returning users” usually exceeds “Total users”. It’s not a bug, it’s just how GA4 works: the same person can be counted as both new and returning in the same date range.
Example: let’s say someone discovers your website on Monday (counted as a “New user”) and comes back on Wednesday (now also counted as a “Returning user”). That’s one person, but they appear in both metrics. So, GA4 double-counts that visitor.
The bottom line is: don’t expect these metrics to add up neatly. Focus on each metric independently, like this:
- Total users = Overall reach.
- Active users = Engaged visitors.
- New users = First-time visitors.
- Returning users = People coming back.
How to use these metrics to understand your business
Each user metric answers a different business question, so choosing the right one depends on what you’re trying to measure. Are you…
- … evaluating campaign reach? Look at “Total users” to understand your full audience exposure.
- … measuring content engagement? “Active users” shows who actually interacted with your website.
- … assessing acquisition efforts? “New users” reveals whether your campaigns are expanding your audience.
- … understanding retention? “Returning users” indicates whether people come back after their first visit.
For most marketing decisions, “Active users” provides the most actionable insights because it separates genuine interest from accidental clicks or immediate bounces.
Pro tip: you can create a calculated metric for “Inactive users” by subtracting “Active users” from “Total users”. This shows you returning visitors who logged a session but didn’t engage, which is helpful for understanding your bounce rate from a different angle.
Also, when you’re building custom reports or analyzing data, consider these tips:
- Default to “Active users” for most analysis. After all, it’s GA4’s primary metric for good reason.
- Add “Total users” when you need to understand full reach, including non-engaged visits.
- Compare New vs. Returning users to balance acquisition and retention efforts.
- Don’t combine metrics mathematically unless you understand the overlap.
Keep in mind: if you’re used to Universal Analytics, remember that “Users” in UA meant “Total users”. In GA4, “Users” means “Active users”.
Final thoughts
Understanding the distinctions between these four metrics helps you ask better questions and achieve more useful interpretations of your data. For example:
- If “Active users” is significantly lower than “Total users”, you might have a landing page problem or targeting issue.
- If “New users” dominates your traffic but “Returning users” stays low, your content might not be compelling enough to bring people back.
- If you’re running acquisition campaigns, track “New users” specifically rather than letting it get lost in “Total users”.
GA4’s shift to “Active users” as the primary metric reflects something important: a hundred engaged visitors who convert or share your content deliver more value than a thousand who bounce immediately. More importantly: these metrics work together to tell your website’s story.
