Editor's note: This post was updated in October 2026 to reflect current Google Analytics functionality, including path exploration and guidance on data retention and sampling.
If you're like most Google Analytics 4 (GA4) users, you may not have experimented with one of the tool's standout features: Explore reports, also called explorations or exploration reports. Explore reports represent a transformative leap into data analysis, providing an invaluable toolkit for organizations and users seeking actionable insights from their data. Let's dive into each report's purpose and when you can use them in lieu of out-of-the-box Google Analytics 4 reporting.
What are GA4 Explore reports and when should I use them?
Explore reports, or explorations, are a set of advanced analysis techniques in Google Analytics that go beyond standard reports. You'll find them under Explore in the left navigation, where you can start from a blank canvas or one of seven templates: free-form, cohort, funnel, path, segment overlap, user explorer, and user lifetime. Google's guide to explorations covers the editor in detail.
I tell teams to pick the technique before they pick the metrics. Each exploration technique answers a different kind of question. Use this table to find the right starting point, then read the details for each technique below.
| If your question is... |
Use this technique |
| How do I compare multiple metrics and dimensions in a custom table or chart? |
Free-form exploration |
| How does behavior change over time for users who share a trait, like when they were acquired? |
Cohort exploration |
| How do prospects become shoppers and then buyers, and where do they drop off? |
Funnel exploration |
| How do users move through the pages, screens, or events on my site or app? |
Path exploration |
| How many users belong to more than one segment, like app users who also visit the website? |
Segment overlap |
| What did a specific user do on my site or app? |
User explorer |
| Which campaigns or channels bring in users with the most long-term value? |
User lifetime |
Free-form exploration
Free-form reporting allows you to create custom reports by dragging and dropping dimensions and metrics. You can easily compare user engagement across different marketing channels or analyze website performance with custom date ranges. With the flexibility found in free-form reporting, you can also import up to 20 dimensions and 20 metrics and apply segments and filters that standard reports don't offer.
Use it when you want to:
- Understand values populated by custom dimensions or metrics
- Drill into a specific event and the custom dimensions or metrics tied to it
- Compare segments of your user base or data with more flexibility through dynamic date ranges and custom segmentation configurations
Cohort exploration
Cohort exploration is all about understanding your users' behavior over time. If you want to dive into your data based on user characteristics, such as acquisition date or specific events, Cohort is the report for you.
Use it when you want to:
- Analyze the retention of users acquired through specific marketing campaigns
- Assess long-term impact on user engagement and key event rates
- Review how product quality affects user retention
Funnel exploration
Funnel explorations are a powerful way to track a user's journey through identified key events or drop-offs. You can create a custom funnel that specifies each step the user takes in their journey through your site or app. You can define up to 10 steps and choose an open funnel, where users can enter at any step, or a closed funnel, where they must start at the first step. Editors and Administrators can also save a funnel exploration as a funnel report for quick access in standard reporting.
Use it when you want to:
- Optimize user experience by pinpointing areas that may be causing trouble in the conversion process
- Analyze the steps taken by a user (or users) from landing on your homepage to completing a purchase
- Review the steps users take to complete a task so you can understand how well (or poorly) they’re performing at each step
Path exploration
Path exploration shows the sequence of pages, screens, or events users move through on your site or app. You can follow paths forward from a starting point or backward from an ending point, which makes it one of the fastest ways to see what users do right before they complete a key event.
Use it when you want to:
- Find what users do before completing a form, purchase, or other key event
- Spot looping behavior that points to confusing navigation
- See which pages users visit before or after a specific page
Segment overlap
Segment overlap analysis in GA4 Explore Reports is essential for understanding the intersection between different user segments. This exploration allows you to compare the characteristics of users who belong to multiple segments. Any segment you build can also become an audience for reporting and remarketing.
Use it when you want to:
- Explore overlap between users who engaged with both your mobile app and website
- See how many users who viewed a product page also went on to make a purchase
- Compare how the age range of your users affects the way they are accessing your app or site (mobile phone vs. tablet)
User explorer
The user explorer allows you to dive deep into individual user profiles, gaining insights into their specific interactions with your site or app. It can be incredibly valuable for understanding user behavior at a very granular level.
Use it when you want to:
- Explore the journey of a user who completed a specific key event
- Understand the individual behavior of a user and their journey through your site
- Dive into a user’s high average order value and what led them to that conversion
User lifetime
The user lifetime report focuses on understanding the long-term engagement of users with your platform. You can use it to track user retention and assess the lifetime value of different user cohorts.
Use it when you want to:
- Analyze how user engagement changes over months or years to identify trends
- Support efforts to build lasting relationships with your audience, maximizing the overall impact of user interactions
- Uncover the campaign, source, and medium of users who have a high lifetime order value
What to know before building a GA4 exploration
Explorations work from event-level data, which gives them their flexibility and also a few limits worth planning around. The biggest is data retention. By default, Google Analytics keeps event-level data for two months, and explorations can only show data inside that window. Standard reports aren't affected, which is why a year-over-year comparison can work in a report and come back empty in Explore. Standard properties can extend retention to 14 months under Admin > Data retention, and the change applies to data you've already collected.
Large queries can also be sampled. On a standard property, that can happen once a query involves more than 10 million events, and the data quality icon in the corner of the exploration turns yellow when it does. Explorations also apply the same privacy thresholds as standard reports. For fully unsampled, event-level analysis, the Google Analytics 4 BigQuery export is the next step.
As your business evolves, so do your reporting needs. Google Analytics explorations feature offers the flexibility to adapt to changing requirements on the fly, ensuring that your analytics strategy remains aligned with your shifting business objectives. Dive into explorations for more actionable data-derived insights and improved decision-making.
