What is Traffic Acquisition in Google Analytics 4 & How it Works [2025]

Traffic Acquisition in GA4 shows you the exact sources of your visitors. It helps you understand if they came through search engines, social media, ads, or by typing your website directly.

For example, if someone types your web address, it’s Direct Traffic. If they find you through Google Search, it’s Organic Traffic. And if they click a link from another website, it’s Referral Traffic.

By checking this report, you can see which source works best for you and focus on the channels that bring the most valuable visitors.

Different Types of Traffic in GA4

In Google Analytics 4 (GA4), traffic is grouped into different types so you can see how visitors find your website.

Although you can see I have 4 options here, like Total, Direct, Organic & Referral Traffic (as a new website), there are more types available. Now I’m going to tell you about all types of traffic in Google Analytics 4 and what they mean.

• Total traffic: The overall number of visitors coming to your site from all sources combined, giving you a big-picture view of your website performance.
• Direct traffic: Visitors who type your website URL directly into their browser or use a bookmark. These are people who already know your site.
• Organic traffic: Visitors who find your site through unpaid search results on search engines like Google or Bing. This shows how well your SEO is performing.
• Referral traffic: Visitors who click a link from another website that leads to yours. For example, a blog post linking to your site.
• Paid traffic: Visitors who come through paid ads, like Google Ads, Facebook Ads, or other advertising campaigns.
• Social traffic: Visitors coming from social media platforms like Facebook, Instagram, LinkedIn, or Twitter.
• Email traffic: Visitors who click links in your email campaigns and newsletters.
• Other campaigns: Visitors from custom campaigns you track using UTM parameters, which can include partnerships, influencer marketing, or affiliate links.

Understanding these traffic types helps you see which channels bring the most visitors and focus on the ones that matter most for your website growth.

2. At the top-right corner, click on the date range selector.

This way, you can analyze traffic trends for any specific time, like comparing last month’s organic traffic with this month’s.

More Options for Date Range in GA4

In GA4 Traffic Acquisition, you can do more than just pick a start and end date. I’m going to tell you about all the date options and how they can help you understand your traffic better:

• Preset ranges: Quickly select common periods like Today, Yesterday, Last 7 days, Last 28 days, Last 90 days, This month, or Last month. These give you a fast snapshot of how your traffic is doing.
• Custom range: Pick any start and end date you want, like during a marketing campaign or product launch, to focus on specific periods.
• Compare date ranges: Look at two periods side by side, for example, this month vs. last month or this week vs. last week, to see how your traffic is growing or changing.
• Relative dates: Check dynamic periods like the last 7 days, last 30 days, or last 12 months, so your data stays current without constantly updating the dates.
• Calendar navigation: Jump quickly to months, weeks, or days using the calendar picker to spot patterns and trends in your traffic.

These options let you understand how your visitors find your site and help you make better decisions for your marketing.

What are The Metrics of Traffic Acquisition in GA4

I’m going to tell you about the Traffic Acquisition metrics in GA4. This will help you understand each metric and how it shows the way visitors reach and engage with your site.

1. Session

A session is the total number of visits to your website. A session starts when someone lands on your site and ends after 30 minutes of inactivity.

For example, in August 2025, I had 81 sessions. This means the site was visited 81 times. If a visitor leaves my site and comes back within 30 minutes, it counts as the same session. If the visitor returns after 30 minutes, GA4 counts it as a new session.

Sessions help you track overall traffic volume. It shows you how many times your site is visited, regardless of the number of unique visitors, and helps you monitor trends over time.

2. Engaged Sessions

Engaged sessions are the number of visits where users stayed for at least 10 seconds, viewed 2 or more pages, or triggered a conversion event. These sessions show meaningful interaction with the site.

For example, in August 2025, I had 37 engaged sessions. This means 37 visits involved visitors actively exploring my site, such as scrolling through pages or clicking links.

Engaged sessions help you track how interested visitors are in your content. It shows how many sessions involve real interaction, not just quick visits.

3. Engagement Rate

Engagement rate is the percentage of sessions that are considered engaged. It shows how many visitors are actively interacting with the site rather than just visiting briefly.

For example, in August 2025, my engagement rate was 45.68%. This means nearly half of all sessions involved meaningful interaction, like viewing multiple pages or triggering events.

Engagement rate helps you understand the quality of your traffic. It shows how well visitors are connecting with your content and which sessions are truly valuable

4. Average Engagement Time per Session

Average engagement time per session measures the typical amount of time visitors actively spend on the site during a single session. It focuses on real interaction, not just page load time.

For example, in August 2025, the average engagement time per session was 28 seconds. This means visitors spent around half a minute actively engaging with my site in each session.

This metric helps you understand how long visitors are paying attention to your content. It also shows if a blog or page is truly valuable longer engagement often means the content is high-quality and interesting.

5. Events per Session

Events per session measures the average number of actions visitors take during a session, such as clicks, scrolls, video plays, or form submissions.

For example, in August 2025, I had 5.22 events per session. This means each visitor interacted with my site around five times on average during a session.

This metric helps you understand how engaging the site is. More events per session usually indicate that visitors find the content interesting and are actively exploring it.

6. Event Count

Event count is the total number of interactions recorded across all sessions on your site, including clicks, scrolls, video plays, and form submissions.

For example, in August 2025, I had a total of 423 events. This means all visitors combined performed 423 actions on my site during that month.

Event count helps you see the overall activity level on your site. Higher event counts usually indicate that visitors are engaging more with content and features, which reflects interest and usability.

7. Key Events

Key events are important actions on your site that are tracked as valuable, like sign-ups, purchases, downloads, or form submissions.

For example, in August 2025, I had 0 key events. I haven’t set up actions like sign-ups, sales, downloads, or forms on my site yet, so no sessions recorded these events.

Key events help measure whether visitors are completing the actions that really matter. Once these are set up, they show how effectively the site drives conversions or other important goals.

8. Session Key Event Rate

Session key event rate shows the percentage of sessions where at least one key event occurred, rather than counting total visits or interactions.

For example, in August 2025, my session key event rate was 0%. Unlike total events or events per session, this metric focuses on whether a session included a valuable action, not just any activity on the site.

This metric helps understand how many sessions actually lead to meaningful outcomes. It’s different from engagement rate or average engagement time because it measures the quality of sessions in terms of goal completion.

9. Total Revenue

Total revenue shows the money generated from your website during a specific period. It tracks actual sales or transactions, unlike metrics such as events or engagement.

For example, in August 2025, my total revenue was $0.00. This is because I haven’t set up products, sales, or paid services on my site yet.

This metric differs from engagement or event metrics because it measures financial outcomes, showing the real monetary impact of the website rather than just user activity.
