Custom funnel reports are an important feature in Google Analytics 4 that helps you understand and improve user journeys. In this guide, we’ll cover everything you need to know about funnel reporting, from its importance to setting it up and using it to grow your business.
Why Funnels Are Essential for Your Business
Funnel reporting helps you track and visualize users' steps toward critical goals important to your business - like completing a purchase, signing up for a service, or filling out a form.
Online user behavior is rarely simple. Your site visitors will often navigate across multiple pages, devices, and channels before making a conversion. With its open and closed funnel options, GA4 gives the freedom and flexibility to analyze all types of journeys towards key business goals, including both strict, linear paths and more dynamic, non-linear journeys. These funnels help you:
Map the full user journey: This shows how users progress through key stages of the journey.
Drop-off points: Identify where users are leaving the funnel.
Improve results: Make use of data to refine and improve performance.
Without these reports, you’re left in the dark about why users aren’t converting.
Step-by-Step Guide to Setting Up GA4 Funnels
Here’s a detailed walkthrough on how to create, analyze, and optimize your funnel reports.
1. Choose the Right Funnel Type
Closed Funnels: Ideal for looking at specific, sequenced paths, such as users starting on a landing page and converting. Funnels in Google Analytics 4 are closed by default. If a user enters at the second step, they are simply not counted in the initial funnel count, but they can still be analyzed separately.
Open Funnels: Open funnels allow users to enter at any step, regardless of whether they completed the previous steps, making them ideal for analyzing non-linear user journeys. The Open Funnel toggle option is located under Settings in the Funnel Exploration reports.
2. Define Your Funnel Steps
Identify key actions: Identify the most important steps in the user journey.
Link to events: It is highly recommended to tie each step to an e-commerce event that is available in GA4. Some examples are “add_to_cart”, “begin_checkout”, and “purchase”. For a lead generation website, it’s recommended to set up and use the lead gen flow that might include “form_start”, and “form_submit’ events.
3. Build Your Funnel in GA4
Navigate to Explore: Find the Explore section on the left-hand navigation menu and select Funnel Exploration.

Open vs Closed funnel: Decide if you would like to keep the funnel closed or toggle it to open.
Add your steps: Enter the steps in your funnel.
Apply necessary filters as needed: Refine your analysis on specific user groups by adding a filter under the Settings section.

4. Save and Organize Your Report
Save the report: Once you have finished configuring your funnel report, you can save your funnel for easy access later.
Add to your library: Drag the report into your Report Library collection.
5. Analyze Key Metrics
Abandonment Rate: Percentage of users who dropped off at a specific step, rather than continuing through the funnel.
Completion Rate: Percentage of users who successfully progressed from one step to the next.
6. Segment Your Data for Deeper Insights
Use dimension breakdowns: The table below the funnel chart allows you to split data by any dimension. For example, if the device category dimension is being used, and mobile users show higher abandonment, then your site might need mobile optimization to improve its user experience. Other important dimensions include geographic location, audiences, and traffic source (i.e. source/medium, default channel groups).

Leveraging GA4 Funnels to Improve Business Results
Now that your funnel reporting is created, here are some ways to improve the bottom line by turning these insights into actionable items that provide tangible value for your business.
1. Identify Friction Points to Boost Conversion Rates
Identifying drop-off sections in the funnel can help you boost conversion rates. As an example, high abandon rates between the "Add to Cart" and "Begin Checkout" might suggest unexpected fees (i.e. shipping) that deter the user from completing the purchase.
2. Enhance User Experience
A smoother user journey can increase user satisfaction and the amount of users returning to your site. CTAs (call-to-action elements) might be misleading or buried, frustrating users and leading them to exit the funnel. Also, slow-loading pages can drive users away. On mobile devices, a funnel that appears clunky can lose its users very quickly.
4. Optimize Marketing Spend and Measure Campaign Effectiveness
Knowing which channels or campaigns work best allows you to manage your budget more efficiently. For example, if the organic search channel outperforms paid ads, it would make sense to prioritize SEO. When analyzing specific campaigns, a closed funnel might reveal if ads are resulting in conversions or dead ends.
Conclusion
Funnel reports are more than simply visualizations. They’re an important tool for defining, refining, and optimizing user experiences and driving important business goals. When configured correctly, they can enable informed data-driven decisions that provide tangible outcomes for your company.
