Where to Find Sessions in Google Analytics 4?

If you've recently moved over to Google Analytics 4, you’ve probably noticed a few key metrics aren’t where you expect them to be. Finding the total number of sessions your site gets is one of the most common hangups for seasoned marketers and business owners alike. This article will show you exactly where to find session metrics in GA4’s standard reports and how to build your own custom reports to analyze them in more detail.

What Exactly Is a "Session" in GA4?

Before we pinpoint where to find session data, it’s important to understand that GA4 defines a session a little differently than Universal Analytics (UA) did. Getting this concept right is the first step to interpreting your new reports accurately.

In GA4, a session is a group of user interactions with your website that take place within a given timeframe. It begins the moment someone lands on your site (when the app runs in the foreground or a page loads). The big change is how it ends.

By default, a session ends after 30 minutes of inactivity. If a user is idle for 31 minutes and then clicks a link, a new session starts. This is similar to UA, but here are the key GA4 differences:

• Sessions Don't Restart at Midnight: In Universal Analytics, if a user started browsing at 11:50 PM and continued past midnight, UA would count it as two separate sessions. GA4 fixes this. A session can now cross the midnight threshold without being artificially split, giving you a more accurate count.
• New Campaigns Don't Start New Sessions: If a user comes to your site from a Facebook ad, leaves, and then comes back 10 minutes later from a Google ad, GA4 counts this as a single session. Universal Analytics would have counted it as two. GA4 now focuses attribution on the events within the session.

These changes are designed to give you a more user-centric view of activity on your site, rather than one chopped up by technicalities.

Meet the "Engaged Session"

You’ll also notice a new metric alongside sessions: Engaged sessions. This is a core concept in GA4 and the primary replacement for "Bounce Rate." To be considered "engaged," a session must meet at least one of these criteria:

• It lasts longer than 10 seconds.
• It included at least one conversion event.
• It had 2 or more page or screen views.

This is a much better indicator of quality traffic. Instead of just knowing who left your site without doing anything, you now see how many visitors actually showed some level of interest.

Where to Find Sessions in Standard GA4 Reports

Let's get into the platform itself. GA4 includes the "Sessions" metric in several standard reports right out of the box. You'll primarily find what you're looking for under the Reports > Acquisition tabs in the left-hand navigation.

1. The Traffic Acquisition Report

This is likely the most useful and direct report for analyzing your session data. It breaks down sessions by the channels that brought visitors to your website (e.g., Organic Search, Direct, Paid Search, Referral).

Here's how to get there:

1. Log in to your GA4 property.
2. In the left-hand menu, click on Reports (the bar chart icon).
3. Under the "Life cycle" section, expand the Acquisition tab.
4. Click on Traffic acquisition.

You'll now see a table where the first column is "Session default channel group." About halfway across the table, you'll see columns for Sessions, Engaged sessions, and Engagement rate. This report answers the fundamental question: "Where is my traffic coming from?" It's perfect for a high-level overview of which marketing channels are driving visits.

Pro-Tip: See the primary dimension "Session default channel group" with the little down arrow next to it? Click on it to change how your sessions are grouped. You can switch to "Session source / medium," "Session campaign," or "Session source" to get a more granular look at performance.

2. The User Acquisition Report

Just above the Traffic acquisition report is one called User acquisition. While it sounds similar, there's a key difference. The User acquisition report looks at how you acquired new users for the very first time, attributing them to their first ever source, medium, or campaign.

It still shows a "Sessions" count, but it's nested within a user-focused model. So, if a new user came from Organic Search, all their subsequent sessions (even if they later come through email) would be grouped under their original "Organic Search" acquisition cohort in this specific report.

This report is more for understanding the longer-term value of your channels rather than immediate session performance.

3. The Landing Page Report

What if you want to see which specific pages are kicking off the most sessions? For this, you’ll want the Landing page report. This report shows the first page a user "landed" on for a given session.

To find it:

1. In the left-hand menu, navigate to Reports > Engagement.
2. Click on Landing page.

Here, you'll see a table listing your top landing pages. And just as in the Acquisition reports, there's a dedicated Sessions column. This perspective is priceless for content marketers and SEOs, as it helps you see which pages are your site's most popular entry points and how engaging they are from the first click.

How to Create a Custom Session Report Using Explorations

The standard reports are great for quick answers, but what if you need to ask more complex questions? What if you want to see sessions from organic search on mobile devices, broken down by country?

For that, you'll need to use GA4’s Explorations feature. This is where the real power of the platform shines. Don't let the name intimidate you, it's a drag-and-drop tool that lets you build your own reports from scratch.

Let's build a simple but useful session report.

Step 1: Open Explorations and Choose "Free form"

In the left-hand menu, click on the Explore icon (it looks like a collection of different chart types). Then, click on the large plus sign box for "Blank exploration."

Step 2: Add Your Dimensions

Dimensions are the things you want to measure your data by. They are typically categorical text attributes. In your new Exploration, you'll see a panel on the left with a "Variables" section. Click the plus sign next to Dimensions.

A list of every available dimension will appear. Use the search bar to find and check the box for each of the following. Let's add a few useful ones for session analysis:

• Session default channel group: The marketing channel.
• Landing page + query string: The specific entry page.
• Device category: Desktop, mobile, or tablet.
• Country: The user's geographic location.

After selecting them, click the blue "Import" button in the top right.

Step 3: Add Your Metrics

Metrics are the numbers you want to see within your report. These are the quantitative measurements.

Back in the "Variables" panel, click the plus sign next to Metrics. Search for and select these essential session metrics:

• Sessions: Your total session count.
• Engaged sessions: How many of those sessions were high-quality.
• Engagement rate: The percentage of sessions that were engaged.
• Conversions: To see if these sessions led to desired outcomes.
• Average session duration: A classic metric to see how long people are sticking around.

Once you've selected these, click "Import."

Step 4: Build Your Report

Now comes the fun part. All your selected Dimensions and Metrics are available to use in the "Tab Settings" panel just a bit to the right.

To build your report, you'll drag and drop variables from the left-hand "Variables" panel into the right-hand "Tab Settings" placeholders:

• Rows: Drag Session default channel group from your dimensions into the "Rows" box. You'll see your table instantly start to build. You can add more dimensions here for a more detailed breakdown. Try adding Device category below it.
• Columns: This is optional. You could drag Device category from Dimensions into the "Columns" box instead to pivot your data differently, showing Desktop, Mobile, and Tablet as separate columns.
• Values: This is where your metrics go. Drag Sessions, Engaged sessions, Engagement rate, and Conversions into the "Values" box. As you add them, new columns of data will populate your report.

Just like that, you have a fully customized report showing your session performance by channel and device, complete with key engagement metrics and conversion data. You can now rename this Exploration something like "Session Performance Dashboard" at the top of the page so it's saved for later.

Putting It All Together: Key Questions to Answer with Session Data

Finding the data is only half the battle. Now you can use these reports to answer critical business questions.

1. "Which marketing channels drive the highest quality traffic?" Use the Traffic Acquisition report (or your custom-built one). Sort by "Engagement rate" instead of "Sessions." A channel might be driving a lot of sessions, but if the engagement rate is low, that traffic isn't very valuable. Is your "Paid Social" generating lots of clicks but poor engagement?

2. "What content is most effective at capturing search traffic?" Head to the Landing Page report. Use the filter controls at the top of the report to only include sessions where the "Session default channel group" contains "Organic Search." Now you'll see a sorted list of your top SEO landing pages and can analyze their engagement rates.

3. "Are my mobile visitors converting as well as desktop visitors?" This is a perfect use case for your custom Exploration. Add "Device category" to your rows and "Conversions" and "Sessions" as your values. You can easily calculate the conversion rate (Conversions / Sessions) for each device to see if you have a performance issue on mobile to address.

Final Thoughts

While GA4 might feel like an entirely new language at first, finding and analyzing session data is straightforward once you know where to look. By combining the standard Acquisition reports for quick snapshots and leveraging Explorations for deep dives, you can gain a much richer understanding of how users truly interact with your website.

Often, the hardest part of data analysis isn't building the report, but simply getting the different tools to talk to each other and knowing what questions to ask. At Graphed, we simplify this process by having our AI connect directly to your data sources like Google Analytics. You can ask for a dashboard showing "line charts of US, Canada, and UK traffic from organic search" in plain English, and have it built in seconds without ever having to navigate GA4's menus.
