Visualize Website Journey Flows with GA4

Available Journey Visualization Methods in GA4

Path Exploration Report: The primary tool for visualizing user journeys. Located under Explore > Path Exploration, this report allows you to:

• View the sequence of pages/screens users visit
• Analyze where users start their journey
• Identify where users drop off
• Segment users based on various dimensions

Key Variables for Journey Analysis

GA4 (Google Analytics 4) provides several powerful variables to help analyze user flows and behavior across your digital properties. These dimensions and metrics enable detailed tracking of how users interact with your content:

• Page path and page title: Track the specific URLs and page names users visit, allowing you to understand the most popular content and navigation patterns through your site.
• Event names: Custom and automatic events that capture specific user interactions like button clicks, form submissions, video plays, scroll depth, and file downloads.
• Session source/medium: Identify where your traffic is coming from, whether it's organic search, paid campaigns, social media, email marketing, or direct visits.
• User demographics: Understand your audience through characteristics like age ranges, gender, interests, and language preferences, helping you tailor content to your visitors.
• Device category: Monitor how users access your site across desktop, mobile, and tablet devices, enabling you to optimize the experience for each platform.
• Geographic location: View user distribution across countries, regions, and cities to understand your global audience reach and adapt content for different markets.

These variables can be combined in custom reports and explorations to gain deeper insights into user behavior and optimize your digital strategy.

Setting Up Journey Analysis in GA4

You can set up journey analysis via the UI or through the API.

Via the UI

• Navigate to the Explore section in your GA4 property dashboard, located in the left navigation menu
• Select Path Exploration from the template gallery to visualize user journey flows
• Choose your starting point by selecting a key entry page or event (e.g., homepage, landing page, or conversion event)
• Select the specific nodes and metrics you want to analyze, such as page views, events, or custom parameters
• Apply segments or filters to focus on specific user groups, time periods, or behaviors for deeper analysis

Via the API

You'll need to use both the pageReferrer and linkUrl dimensions to get comprehensive journey data in GA4. These complementary dimensions work together to provide a complete picture of user navigation patterns and behavior flows.

Key GA4 Journey Dimensions

pageReferrer

Tracks the full URL of the previous page that led to the current page view, enabling precise path analysis

• Essential for mapping internal navigation patterns and understanding how users move between pages within your site
• Captures server-side page transitions and provides reliable data even when client-side tracking is limited

linkUrl

Captures the destination URLs of links clicked by users, providing predictive journey insights

• Reveals user intentions by showing which links they interact with before leaving the current page
• Critical for tracking both internal navigation patterns and external link interactions across your digital properties

Data Collection Process

To get complete journey data, you need to:

• Query both dimensions separately since they capture different aspects of the journey:
• pageReferrer provides historical context by revealing the user's previous location
• linkUrl indicates user intent by showing their next destination
• Combine and normalize the data:
• Standardize relative paths into complete, canonical URLs for consistent analysis
• Calculate meaningful session metrics to understand volume and frequency
• Apply special handling for homepage visits and direct traffic patterns

Implementation Considerations

• Implement robust regex patterns to handle URL variations and ensure accurate path matching
• Standardize URL formats by accounting for trailing slashes and query parameter variations
• Configure proper hostname matching rules for websites spanning multiple domains or subdomains
• Weight journey analysis using session counts to identify significant patterns
• Build comprehensive error handling to manage API timeouts and data anomalies
• Select appropriate date ranges to balance data volume with meaningful insights

Data Processing Steps

• Execute parallel API requests to efficiently gather both pageReferrer and linkUrl data sets
• Transform URLs into a standardized format following your organization's conventions
• Merge the dimension data sets to create comprehensive journey mappings
• Order results by session volume to identify primary user paths
• Consolidate low-traffic destinations into an "Other" category for cleaner analysis
• Implement exception handling for missing data and invalid URL formats

Here is some example Python code to get you going:

from google.analytics.data_v1beta import BetaAnalyticsDataClient
		   from google.analytics.data_v1beta.types import (
		       RunReportRequest,
		       Dimension,
		       Metric,
		       DateRange,
		       Filter,
		       FilterExpression,
		       FilterExpressionList,
		       OrderBy
		   )

		   def analyze_ga4_journeys(property_id, landing_page, start_date, end_date):
		       """
		       Analyze user journey data in GA4 by combining pageReferrer and linkUrl
		       dimensions to understand both where users came from and where they're going.
    
		       Args:
		           property_id: GA4 property ID
		           landing_page: Page path to analyze (e.g., '/blog/post-1')
		           start_date: Start date in YYYY-MM-DD format
		           end_date: End date in YYYY-MM-DD format
    
		       Returns:
		           dict: Combined journey analysis results
		       """
		       client = BetaAnalyticsDataClient()

This comprehensive approach ensures you capture the complete user journey by combining both historical navigation data and forward-looking user intentions, enabling sophisticated path analysis and optimization opportunities.

Limitations of GA4 Journey Visualization

While GA4 provides powerful analytics capabilities, it comes with several notable limitations when it comes to journey visualization and analysis:

Complex Setup Requirements

Implementing custom events and setting up proper journey tracking in GA4 requires significant technical expertise. Content teams often need developer support to properly configure event tracking and ensure accurate data collection.

Limited Data Retention

GA4's standard data retention policies can restrict your ability to analyze long-term trends. By default, user-level and event-level data is only kept for a limited time period, making it challenging to perform historical analysis of user journeys beyond this window.

Steep Learning Curve

The GA4 interface represents a significant departure from Universal Analytics, requiring users to learn new terminology, navigation patterns, and reporting structures. This can slow down adoption and make it difficult for teams to quickly access the insights they need.

Visualization Constraints

While GA4 offers basic journey visualization tools, the options for customizing and presenting this data are somewhat limited. Users often find themselves needing additional tools to create more intuitive and shareable visualizations of user flows.

API Implementation Challenges

For teams looking to programmatically access journey data, GA4's API implementation can be complex and requires substantial development resources. The learning curve for working with the API is steep, and documentation can be challenging to navigate for non-technical users.
