Why GA4 Funnel Explorations Matter More Than Ever
If you run an online store or a lead-generation website, you already know the painful truth: most visitors leave without converting. Industry benchmarks show that the average e-commerce conversion rate hovers around 2–3%. That means 97 out of 100 visitors walk away.
The question isn’t whether you’re losing people—it’s where and why.
That’s exactly what GA4 funnel explorations are designed to answer. Unlike the basic reports in Google Analytics 4, funnel explorations let you build custom, multi-step visualizations of the user journey. You define the steps, choose whether the funnel is open or closed, layer on segments, and watch where the leaks happen.
Universal Analytics had a limited version of this (the old “Goal Flow” report), but GA4’s exploration workspace is dramatically more flexible. If you haven’t set one up yet, this guide will take you from zero to actionable insights.
Understanding the GA4 Exploration Workspace
Before diving into funnels specifically, let’s quickly orient ourselves in GA4’s Explore section. When you click “Explore” in the left sidebar, you’ll see several templates:
- Free-form exploration – pivot tables, charts, scatter plots
- Funnel exploration – the star of this article
- Path exploration – tree-graph style analysis of user navigation
- Segment overlap – Venn diagrams of audience segments
- Cohort exploration – retention and behavior over time
- User lifetime – LTV analysis
The funnel exploration template is where you’ll build step-by-step conversion funnels. It uses a drag-and-drop interface with three panels:
- Variables (left) – dimensions, metrics, segments, date range
- Tab settings (middle) – funnel configuration (steps, filters, breakdowns)
- Visualization (right) – the actual funnel chart and data table
This three-panel layout can feel overwhelming at first, but once you understand the logic, it’s remarkably powerful.
Step-by-Step: Creating Your First Funnel Exploration
Step 1 — Open a New Funnel Exploration
- Go to Explore → click Funnel exploration from the template gallery.
- GA4 loads a default funnel with placeholder steps (usually
first_open/first_visit→ some event → a purchase). Delete these. - Name your exploration something descriptive, like “Checkout Funnel – Q1 2025.”
Step 2 — Define Your Funnel Steps
Click the pencil icon next to “Steps” in the Tab Settings panel. This opens the step editor.
For a typical e-commerce checkout funnel, you’d define steps like this:
| Step | Event / Condition | Description |
|---|---|---|
| 1 | view_item | User views a product page |
| 2 | add_to_cart | User adds the product to cart |
| 3 | begin_checkout | User starts the checkout process |
| 4 | add_shipping_info | User enters shipping details |
| 5 | add_payment_info | User enters payment information |
| 6 | purchase | Transaction completed |
Each step can be based on an event name, a page path, or a combination with parameter conditions. For example, you could make Step 1 more specific:
Event =
page_viewAND Page path contains/product/
This flexibility is one of GA4’s biggest advantages over Universal Analytics.
Step 3 — Choose Open or Closed Funnel
Right below the steps editor, you’ll see a toggle: “Make open funnel.”
- Closed funnel (default): Users must enter at Step 1. If someone jumps directly to
begin_checkoutwithout a trackedview_itemevent, they’re excluded. - Open funnel: Users can enter at any step.
Recommendation: For checkout analysis, keep the funnel closed. For content funnels (e.g., blog → signup → onboarding), an open funnel often provides richer data because users don’t always follow a linear path.
Step 4 — Add Segments for Comparison
This is where funnel explorations become truly insightful. In the Variables panel, click the + next to Segments and create comparisons like:
- Mobile vs. Desktop users
- Organic Search vs. Paid Search traffic
- New visitors vs. Returning visitors
- Country A vs. Country B
You can compare up to 4 segments side by side. Drag them into the “Segment Comparisons” area in the Tab Settings panel.
Step 5 — Add a Breakdown Dimension
Below the segment comparisons, you’ll find the Breakdown option. Drag a dimension here (e.g., Device category, Country, or a custom dimension like membership_tier) to split each funnel step into sub-categories.
For example, breaking down by Device category might reveal that mobile users drop off at a 68% rate on the shipping info step while desktop users only drop off at 41%. That single insight can justify an entire UX redesign of your mobile checkout.
Step 6 — Analyze and Interpret
Once your funnel renders, GA4 displays:
- Bar chart showing users at each step
- Completion rate between steps (and overall)
- Abandonment rate at each step
- Elapsed time between steps (toggle this on in settings)
Look for the biggest single drop-off first. That’s your highest-leverage optimization opportunity.
Real-World Example: How a 28% Drop-Off Became a 9% Drop-Off
Let’s walk through a concrete scenario. A mid-sized fashion e-commerce store running on PrestaShop (a platform Lueur Externe has deep certified expertise in) had the following funnel metrics:
| Step | Users | Drop-off Rate |
|---|---|---|
| View Product | 45,200 | — |
| Add to Cart | 11,300 | 75% |
| Begin Checkout | 7,910 | 30% |
| Shipping Info | 5,695 | 28% |
| Payment Info | 4,840 | 15% |
| Purchase | 4,118 | 15% |
The biggest controllable drop-off was at the Shipping Info step: 28% of users who started checkout abandoned when asked for shipping details.
By breaking this down by Device category, the team discovered that on mobile, the drop-off was actually 41%, while on desktop it was only 14%. The mobile shipping form required scrolling through a long list of fields that didn’t auto-fill properly.
The fix:
- Implemented address auto-complete via the Google Places API
- Reduced form fields from 9 to 5
- Added a progress indicator at the top of the checkout
After two weeks, the same funnel exploration showed the Shipping Info drop-off had fallen to 9% on mobile and 8% on desktop. Overall conversion rate increased from 9.1% (of checkout starters) to 14.7%—a 61% improvement in checkout completion.
This is the kind of data-driven optimization that pays for itself many times over.
Advanced Techniques for Power Users
Trended Funnels
In the Tab Settings panel, change the visualization type from Standard funnel to Trended funnel. Instead of a bar chart, you’ll see a line chart showing how completion rates change over time.
This is invaluable for:
- Measuring the impact of a site redesign
- Detecting seasonal patterns
- Spotting sudden regressions (e.g., a broken form field after a deployment)
Elapsed Time Analysis
Toggle on “Show elapsed time” to see the median time between each step. If users take an average of 8 minutes between add_to_cart and begin_checkout, something might be creating friction or hesitation—perhaps unclear shipping costs or a confusing cart page.
Using Custom Events as Funnel Steps
GA4 lets you fire custom events via Google Tag Manager. This opens up creative funnel possibilities beyond the standard e-commerce flow:
// Example: Fire a custom event when a user interacts with a size guide
dataLayer.push({
event: 'size_guide_opened',
item_category: 'dresses',
interaction_method: 'modal'
});
// Example: Fire when a user applies a discount code
dataLayer.push({
event: 'discount_code_applied',
coupon_code: 'SUMMER25',
discount_value: 25
});Now you can build a funnel like:
view_itemsize_guide_openedadd_to_cartpurchase
This tells you whether users who engage with the size guide convert at a higher rate—and by how much. If they do, you know to make the size guide more prominent.
Funnel Segments as Audiences
Here’s a powerful but under-used trick: right-click on any bar in the funnel chart and select “Create segment” or “Create audience.” GA4 lets you build a retargeting audience from users who dropped off at a specific step.
For instance, create an audience of users who completed begin_checkout but never reached purchase, then push that audience to Google Ads for a targeted remarketing campaign with a 10% discount incentive. At Lueur Externe, this is one of the strategies we frequently implement for e-commerce clients, and it consistently delivers 3–5x higher ROAS compared to generic remarketing.
Common Mistakes to Avoid
Even experienced analysts make these errors when setting up funnel explorations:
- Too many steps. GA4 supports up to 10, but funnels with more than 7 steps become hard to read and act on. Keep it focused.
- Using page_view instead of specific events. If your checkout is a single-page app,
page_viewwon’t capture micro-steps. Use custom events. - Ignoring the “indirectly followed” option. By default, GA4 sets steps to “is indirectly followed by,” meaning other events can happen between steps. If you need strict sequential behavior, switch to “is directly followed by.”
- Not filtering out internal traffic. Employees, developers, and QA testers can heavily skew funnel data, especially for smaller sites. Apply a filter or segment to exclude internal IP addresses or a custom
traffic_typedimension. - Analyzing too short a date range. Funnels need volume to be statistically meaningful. If your site gets 500 visits per day, a single day’s funnel data is nearly useless. Use at least 2–4 weeks of data.
GA4 Funnels vs. Third-Party Tools
You might wonder how GA4 funnel explorations compare to dedicated tools like Mixpanel, Amplitude, or Hotjar Funnels. Here’s a quick comparison:
| Feature | GA4 Funnel Exploration | Mixpanel / Amplitude | Hotjar Funnels |
|---|---|---|---|
| Cost | Free | Free tier limited; paid plans $25–2,000+/mo | Free tier limited; paid from $40/mo |
| Max funnel steps | 10 | 20+ | 5 (page-based) |
| Segment comparisons | Up to 4 | Unlimited | Limited |
| Retroactive data | Yes (within retention period) | Yes | No (must pre-define) |
| Integration with Google Ads | Native | Requires export | None |
| Session recordings | No | No (Amplitude) / limited (Mixpanel) | Yes |
| Ease of setup | Moderate | Moderate | Easy |
For most small-to-medium businesses, GA4 provides 80–90% of the funnel analysis capability you need, at zero cost. The native Google Ads integration alone makes it the pragmatic choice for teams running paid campaigns.
When you need session recordings alongside funnel data, pairing GA4 with a tool like Hotjar or Microsoft Clarity is the sweet spot.
Turning Funnel Insights into Action: A Framework
Data without action is just trivia. Here’s a simple framework for converting funnel insights into revenue:
- Identify the step with the highest drop-off rate.
- Segment that step by device, traffic source, and user type to narrow the problem.
- Hypothesize why users are leaving (UX issue? trust issue? performance issue?).
- Validate with qualitative data—session recordings, user surveys, heatmaps.
- Test a fix via A/B testing (Google Optimize may be gone, but tools like VWO, AB Tasty, or Convert work perfectly).
- Measure the impact using the same funnel exploration with the same date-range length.
- Iterate by moving to the next biggest drop-off.
This cycle, repeated quarterly, compounds. A site that reduces drop-off by even 5 percentage points at two funnel steps can see overall conversion rates jump by 20–40% over a year.
