What is Segment?
TL;DR
A subset of analytics data based on specific criteria, mobile users, visitors from a particular city, converters, or any filterable dimension. Segments let you compare behaviors across groups: do mobile users convert differently than desktop? Does paid traffic engage more than organic? Google-analytics-4 uses segments extensively in explorations. Creating useful segments is an analytics superpower. Standard segments include device, geography, and traffic source. Advanced segments might be "users who viewed 3+ service pages but didn't convert" or "returning visitors who came from email." Segment-based analysis reveals insights hidden in aggregate data. Your overall Conversion Rate might be 2%, but if mobile is 0.5% and desktop is 4%, you have a specific mobile problem to solve, not a general conversion problem.

Frequently Asked Questions About Segment
What is a segment in analytics?
A subset of your data based on criteria you define, mobile users, visitors from Google Ads, people who converted, users from a specific city. Segments let you analyze specific groups separately from aggregate data.
Why are segments important for analysis?
Aggregate data hides important differences. Overall conversion might be 2%, but if mobile is 0.5% and desktop is 4%, you have a specific mobile problem, not a general problem. Segments reveal where to focus improvements.
What segments should I create first?
Start with device (mobile vs desktop), traffic source (organic vs paid vs direct), and converters vs non-converters. Then add business-specific segments like service interest, location, or customer type based on what matters to your business.
How do I create segments in GA4?
In Explorations, add segments by clicking the + icon in the Segments panel. Choose conditions (user, session, or event segments) and define your criteria. Save frequently-used segments for quick access.
