Once you've implemented event tracking in Google Analytics 4, the next step is to transform that data into actionable insights through effective reporting. This guide will show you how to build custom dashboards and reports that go beyond GA4's standard reports.

Understanding GA4's Exploration Reports

GA4's Exploration reports provide powerful tools for analyzing your event data:

Types of Exploration Reports

GA4 offers several report types for different analysis needs:

• Free Form Exploration: Drag-and-drop interface for customizable reports

• Funnel Exploration: Visualize conversion paths and drop-off points

• Path Exploration: Track the sequence of pages and events users take

• Segment Overlap: Compare different user segments with Venn diagrams

• User Lifetime: Analyze user value and engagement over time

• Cohort Analysis: Track groups of users who share common characteristics

• User Segment: Create detailed audience definitions for analysis

Creating Your First Custom Report

Let's start by building a basic event analysis report:

Free Form Exploration Example

1. In GA4, navigate to Explore in the left menu

2. Click the Free form template

3. In the Variables tab on the right:

   • Add "Event name" as a dimension

   • Add "Event count" and "Total users" as metrics

4. Drag "Event name" to the Rows section

5. Drag "Event count" and "Total users" to the Values section

6. Apply date range and any necessary filters

[GUIDED DEMO: Building Your First GA4 Exploration Report] Video Description: A 5-minute walkthrough of creating a custom event analysis report in GA4's Exploration section. The screencast begins at the GA4 homepage and shows clear navigation to the Explore section. With deliberate cursor movements, the demonstration shows how to select the Free Form exploration template, then add dimensions and metrics to the report. The video highlights how to customize the report layout by dragging elements to different sections, applying filters to focus on specific events, and changing visualization types. The demonstration includes adding calculated metrics (like conversion rate) and applying segments to compare different user groups. The video concludes by showing how to save the custom report and share it with team members, with all cursor movements clearly visible and important UI elements highlighted.

Advanced Funnel Analysis for Events

Create custom conversion funnels to analyze user journeys:

Building an Event-Based Funnel

1. Start a new Funnel exploration
   
   

2. Add the following steps (customize based on your events):
   
   
   

   • Step 1: Event name = page_view (for homepage)

   • Step 2: Event name = click (for product clicks)

   • Step 3: Event name = view_item (for product detail views)

   • Step 4: Event name = add_to_cart

   • Step 5: Event name = begin_checkout

   • Step 6: Event name = purchase

3. Customize the funnel:
   
   
   

   • Make steps optional or required

   • Set time constraints between steps

   • Add segment comparisons

[IMAGE: Event Funnel Analysis] Description: Create a detailed visualization of an event-based conversion funnel analysis. Design the image as a GA4 funnel exploration report showing a complete e-commerce conversion path. The funnel should start wide at the top with "Page View: Homepage" (showing perhaps 10,000 users), then narrow through subsequent stages: "Product Click" (perhaps 5,000 users), "Product View" (3,000 users), "Add to Cart" (1,500 users), "Begin Checkout" (800 users), and finally "Purchase" (500 users). Each stage should be a different color with clear percentage drop-offs labeled between stages. On the right side, include a segment comparison panel showing how the funnel performs for different user types (e.g., "New Users" vs "Returning Users" vs "Subscribers") with differently colored lines showing their respective conversion rates. Below the main funnel, add a "Time Between Steps" section showing the average time users spend between each funnel stage. The visualization should look professional and data-rich, similar to what a marketing analyst would actually use when analyzing conversion paths in GA4.

Custom Event Segments for Deeper Analysis

Create segments to compare different user behaviors:

Event-Based Segment Examples

1. Power Users Segment:
   
   

   • Users who triggered specific events more than X times

   • Example: "video_complete" event count > 5

2. Engaged Readers Segment:
   
   

   • Users who reached 90% scroll depth on more than 3 pages

3. Comparison Shopping Segment:
   
   

   • Users who viewed more than 5 products but haven't purchased

Creating a Custom Segment:

1. In your exploration, click the "+" next to Segments

2. Name your segment (e.g., "Power Video Viewers")

3. Add condition: Event name = video_complete

4. Set threshold: Event count per user > 5

5. Save and apply to your report

[GUIDED DEMO: Creating Powerful Event-Based Segments] Video Description: A 4-minute technical demonstration showing how to create advanced event-based segments in GA4. The screencast begins in the GA4 Exploration section and shows the process of creating a new user segment. With clear cursor movements, the video demonstrates how to build segment conditions based on event data, including combining multiple event conditions (such as users who completed videos AND downloaded content). The demonstration shows how to set thresholds for event frequency, recency, and value, with each option clearly highlighted. The video then applies the newly created segment to different report types to show how it can be used for comparison analysis. The screencast concludes with saving the segment for future use and demonstrating how to access the segment library, with all important UI elements and options clearly visible.

Custom Calculated Metrics

Create advanced metrics beyond what GA4 provides by default:

Example Calculated Metrics

Engagement Rate:

{{Engaged Sessions}} / {{Sessions}}

Video Completion Rate:

{{video_complete}} / {{video_start}}

Add-to-Cart Rate:

{{add_to_cart}} / {{view_item}}

Event Value Per User:

{{Event Value}} / {{Total Users}}

To Create a Calculated Metric:

1. In your exploration, click "+" next to Metrics

2. Name your metric (e.g., "Video Completion Rate")

3. Create the formula using available metrics

4. Format the result (percentage, decimal, etc.)

5. Save and add to your report

Visualizing Event Flow and User Journeys

Understand the sequences of events that users trigger:

Path Exploration for Event Sequences

1. Start a new Path exploration

2. Set up your path analysis:

   • Node dimension: "Event name"

   • Start node: Select your initial event (e.g., "session_start")

   • Optional: Add segment comparisons

3. Analyze the resulting path visualization to see common event sequences

This analysis reveals how users naturally move through your site and which event sequences are most common.

Implementation Tip: When setting up path exploration, consider adding a "Page title" or "Page location" node after important events to see which pages those events occur on.

Custom Reports for Specific Event Types

Different events require different analysis approaches. Here are some specialized reports for common event types:

Form Interaction Analysis

1. Create a Free form exploration

2. Add dimensions:

   • "Event name" (filtered to form events)

   • "Page title" where forms appear

   • Form field parameters (custom)

3. Add metrics:

   • Event count

   • Form abandonment rate (calculated)

   • Average form completion time (custom)

4. Create visualizations:

   • Bar chart of form submission rates by page

   • Table of abandonment by form field

   • Line chart of submissions over time

[GUIDED DEMO: Form Performance Analysis Dashboard] Video Description: A 5-minute screencast demonstrating how to build a comprehensive form analysis dashboard in GA4. The demonstration begins by showing how to identify form-related events in your data. With clear cursor movements, the video shows the process of adding relevant dimensions and metrics to analyze form performance, including field-level abandonment tracking. The screencast then demonstrates how to build visualizations that reveal which form fields cause the most drop-offs, which forms have the highest completion rates, and how form performance trends over time. The video includes creating calculated metrics for form conversion rate and showing how to apply segments to compare form performance between different user types (mobile vs desktop, new vs returning). All clicks and interface interactions are clearly visible with slight pauses at key configuration steps.
