Explorations are where GA4 stops handing you a fixed report and lets you build your own. That freedom is also the trap. It is easy to spend an hour dragging dimensions around and end up with a nice table that answers nothing. So start with a question that could change a decision, and let it pick the technique.
Match the question to the technique
GA4 offers seven techniques. These four cover most everyday questions:
- "How does this metric compare across these groups?" Use a free-form exploration.
- "Where do people drop out of a sequence I have defined?" Use a funnel exploration.
- "What did people do before or after this step, when I do not know the route?" Use a path exploration.
- "How many people belong to several groups at once?" Use segment overlap.
The other three are cohort exploration, user exploration and user lifetime. Cohorts are useful when your question is about people returning over time, and user lifetime when it is about their value over a longer period.
A useful question names a group, a behaviour, a period and what you would do with the answer. "How is the website doing?" is not one. "Do mobile visitors drop out of the enquiry process earlier than desktop visitors, and should we test the form first?" is.
Check two settings before you trust anything
First, check data retention. Date ranges in explorations are limited to your property's retention setting, and the default is 2 months. Standard properties can choose 14 months. If you select a whole year on a 2-month property, the older days are simply left out, so the result can look like a real low point. Check this in Admin before comparing long periods.
