Active Users
Last updated: Sep 10, 2025
What is Active Users?
Active Users in GA4 represents the number of distinct users who engaged with your website or app during a specified time period. A user is considered "active" when they trigger an engagement session, which occurs when they stay on your site for 10 seconds or longer, have a conversion event, or have 2 or more page or screen views. This metric provides a foundational understanding of your audience size and engagement levels, replacing the traditional "Users" metric from Universal Analytics with a more engagement-focused approach. Unlike simple visitor counts, Active Users emphasises meaningful interaction with your content, filtering out users who immediately bounce or show no genuine interest in your site. This makes it a more reliable indicator of your actual engaged audience size.
Active Users Formula
How to calculate Active Users
A retail website wants to understand their weekly active user base. Looking at their GA4 data for the week of March 1-7, they see: Monday: 2,500 active users Tuesday: 2,800 active users Wednesday: 3,200 active users Thursday: 3,400 active users Friday: 4,100 active users Saturday: 3,900 active users Sunday: 3,100 active users Their total Active Users for the week would be 23,000. However, it's important to note that this represents unique users across the entire week, not the sum of daily totals, as the same user visiting on multiple days is only counted once in the weekly total.

What is a good Active Users benchmark?
Active Users doesn't typically have universal benchmarks since it's an absolute count that varies dramatically by industry, business size, and market reach. However, marketers often establish internal benchmarks by comparing period-over-period performance (month-over-month growth rates of 10-20% are often considered healthy for growing businesses) or seasonal patterns. More meaningful comparisons come from looking at Active Users as a percentage of total traffic or examining active user growth rates rather than absolute numbers.
More about Active Users
Active Users serves as a crucial foundation metric for understanding audience engagement and calculating other important ratios like conversion rates and revenue per user. It's particularly valuable for assessing the health of your user acquisition efforts and identifying trends in audience engagement over time. When analysing Active Users, segment the data by traffic source, device type, and geographic location to uncover insights about which channels drive the most engaged visitors.
One key application is using Active Users to evaluate the effectiveness of marketing campaigns by comparing active user counts before, during, and after campaign periods. It's also essential for cohort analysis, helping you understand user retention patterns and the long-term value of different user acquisition strategies. However, be cautious when comparing Active Users across different date ranges, as seasonality, campaign timing, and external factors can significantly impact these numbers.
Common challenges include understanding that Active Users can appear lower than traditional user counts due to the engagement requirement, and recognising that the metric can be influenced by technical factors like site speed or user experience issues that prevent users from reaching the 10-second engagement threshold.
Active Users Frequently Asked Questions
Why are my Active Users numbers lower than my previous Universal Analytics Users numbers?
This discrepancy is expected and stems from GA4's more stringent definition of user engagement. Universal Analytics counted any user who triggered a session, regardless of engagement level, whilst GA4 only counts users as "active" when they demonstrate meaningful engagement through 10+ second sessions, multiple page views, or conversion events. This filtering effect means GA4's Active Users metric represents a higher-quality, more engaged audience segment, which is generally more valuable for business analysis despite the lower absolute numbers.
Should I focus on daily, weekly, or monthly Active Users for my reporting?
The optimal reporting period for Active Users depends on your business model and user behaviour patterns. E-commerce and content sites often benefit from daily Active Users monitoring to quickly identify trends and respond to issues, whilst B2B companies or services with longer consideration cycles may find weekly or monthly views more meaningful. Monthly Active Users (MAU) is particularly valuable for understanding overall audience growth and retention, as it smooths out daily fluctuations and provides a clearer picture of your sustained user base. Consider using multiple timeframes: daily for operational monitoring, weekly for tactical adjustments, and monthly for strategic planning and trend analysis.
