The change in session definition between Google Analytics 3 (GA3) and Google Analytics 4 (GA4) could skew data in several ways, impacting how businesses interpret user behavior, engagement, and overall site performance. Here’s a breakdown of potential impacts due to the new session counting method in GA4:
Potential Skews in Data Due to New Session Definition in GA4
1. Extended Single Session Counts Across Midnight
-
- GA3: Sessions automatically end at midnight, so a user browsing a site late at night and continuing past midnight would trigger two separate sessions.
- GA4: Does not end sessions at midnight. The same activity would count as a single session if the user’s last activity is before midnight and continues after midnight without a 30-minute inactivity gap.
- Impact: This can reduce the total number of sessions reported in GA4 compared to GA3, which could make the site appear to have fewer visits. For businesses tracking session-based metrics to assess performance, such as sessions per campaign, this could undervalue night-time marketing efforts or content releases.
2. Engagement-Based Session Qualification
-
- GA3: All user interactions are treated the same, with every session counted regardless of user engagement level.
- GA4: Introduces the concept of an “engaged session,” which must last at least 10 seconds, involve two or more page views, or result in a conversion.
- Impact: This could skew engagement metrics upwards, as sessions that do not meet the engagement criteria are not counted as “engaged sessions.” This makes the average engagement seem higher than it might have been under GA3’s more inclusive session counting. Businesses may overestimate the effectiveness of user engagement strategies if they do not account for this change.
3. User Behavior Misinterpretation
-
- GA3 vs. GA4 Differences: The elimination of the midnight session reset and the definition of engaged sessions can alter the interpretation of user behavior patterns. For instance, a user who browses during late hours and engages minimally would have counted for more in GA3 due to the session reset at midnight.
- Impact: Businesses might misinterpret user availability and engagement patterns without adjusting for these differences, potentially misaligning marketing strategies. For example, the apparent reduction in late-night sessions could lead to decreased focus on optimizing night-time user experiences or marketing campaigns targeted at late-hour users.
4. Comparison and Trend Analysis Challenges
-
- Historical Data: Comparing historical data from GA3 with current data from GA4 can be misleading due to these definitional changes. Trends that seem to show changes in user behavior might actually reflect changes in tracking and definitions rather than real changes in user actions.
- Impact: Businesses risk making decisions based on distorted trends. For example, a perceived drop in session counts could lead to unwarranted changes in website layout or user engagement strategies.
Recommendations for Businesses
To mitigate these potential data skews:
- Educate your team about the differences in metrics and session definitions between GA3 and GA4.
- Use transitional analytics setups where both GA3 and GA4 run concurrently to understand the differences in data reporting better.
- Revise KPIs and benchmarks to align with the new definitions and tracking methods in GA4.
- Consult with data analysts to adjust historical data comparisons or to develop new models that can accommodate changes brought by GA4.
Understanding these nuances is crucial as businesses transition to GA4, ensuring that interpretations of analytics continue to support informed decision-making rather than being led astray by definitional changes.
