Path Exploration is how you actually see what your users are doing—not just individual events, but the complete journey from entry to exit. Most of the time you're staring at aggregated metrics that hide the real story. Path Exploration shows you the exact sequences users take, so you can spot where they drop off, what they do after a conversion, or whether your navigation makes sense.
What Path Exploration Actually Does
Path Exploration is a custom exploration type in GA4 that maps user journeys as sequences of steps.
Understand the Basic Concept
Path Exploration visualizes user movement through your site or app as a flow diagram. Each step represents a page view or event, and lines show how users move from one step to the next. Unlike the Funnel Analysis report which is prescriptive (users must follow a specific path), Path Exploration is exploratory—it shows you what users actually do without forcing them into a sequence.
// GA4 tracks page views and events automatically
// These become the 'steps' in Path Exploration
gtag('event', 'page_view', {
page_path: '/pricing',
page_title: 'Pricing Page'
});
gtag('event', 'scroll', {
percent_scrolled: 75
});Know What Counts as a Step
In Path Exploration, each step is either a page view (for web) or a screen_view (for app) or a custom event you define. The step can be grouped by page title, page path, or event name. You're essentially asking: 'Show me the most common sequences of [X] through [Y].'
// Define custom events to track specific actions
gtag('event', 'lead_form_start', {
form_id: 'contact_form_v2',
form_location: 'homepage'
});
gtag('event', 'lead_form_submit', {
form_id: 'contact_form_v2',
form_completion_status: 'completed'
});Setting Up and Running Path Exploration
Path Exploration is accessed through GA4's custom explorations. It's already available; you just need to create the exploration and choose your step definitions.
Navigate to the Exploration Builder
In GA4, go to Explorations (left sidebar) and click Create new exploration. Choose Path Exploration as your analysis type. This opens a canvas where you define what constitutes a 'step' in your path.
// Query path data programmatically via the Analytics Data API v1beta
const {BetaAnalyticsDataClient} = require('@google-analytics/data');
const analyticsDataClient = new BetaAnalyticsDataClient();
const request = {
property: `properties/YOUR_GA4_PROPERTY_ID`,
requests: [
{
dimensions: [
{name: 'pagePath'},
{name: 'pageTitle'}
],
metrics: [
{name: 'sessions'},
{name: 'bounceRate'}
],
dateRanges: [{startDate: '30daysAgo', endDate: 'today'}]
}
]
};
const response = await analyticsDataClient.batchRunReports(request);Define Your Starting and Ending Steps
Select what counts as a starting step (e.g., landing on your homepage or a specific event like 'add_to_cart'). Then define the ending step (e.g., completing a purchase or leaving the site). GA4 will show all paths between these two points.
// Example: Track entry point to conversion
gtag('event', 'page_view', {
page_path: '/products',
page_title: 'Product List'
});
// Later in the user session...
gtag('event', 'purchase', {
transaction_id: 'txn_12345',
value: 99.99,
currency: 'USD',
items: [
{item_id: 'prod_456', item_name: 'Widget Pro'}
]
});Group Steps by a Dimension
Choose how to segment your steps. Group by page path to see which pages users visit in sequence. Group by event name if you want to track user actions. You can also group by custom dimensions like campaign or user_segment.
// Send a custom dimension to segment your path exploration
gtag('event', 'page_view', {
page_path: '/checkout',
page_title: 'Checkout Page',
user_segment: 'premium', // Custom dimension
traffic_source: 'organic'
});
// Later, filter Path Exploration by user_segment dimension
gtag('event', 'checkout_started', {
user_segment: 'premium',
cart_value: 250.00
});Reading and Acting on Path Exploration Results
Once your Path Exploration runs, you get a Sankey diagram showing how traffic flows. Here's how to interpret it.
Identify Bottlenecks and Abandonment
Look for steps where the flow narrows significantly. If 100 users start at your homepage but only 20 reach your pricing page, something in between is stopping them. Hover over the connections to see exact drop-off percentages. This is where most of your optimization work should focus.
// Track micro-events to pinpoint where users abandon
gtag('event', 'pricing_page_viewed', {
page_path: '/pricing',
page_title: 'Pricing',
traffic_source: document.referrer
});
gtag('event', 'pricing_cta_clicked', {
cta_text: 'Start Free Trial',
cta_location: 'hero',
cta_position: 1
});
// Compare ratios in Path Exploration to diagnose drop-offSpot Unexpected User Sequences
Path Exploration often reveals that users take odd journeys—like going to checkout, then back to the homepage, then to FAQ. These aren't errors; they're real user behavior. Use these insights to understand decision-making patterns and optimize information architecture or trust signals.
// Log unusual or decision-critical journey checkpoints
gtag('event', 'user_journey_checkpoint', {
checkpoint_name: 'faq_visited_post_checkout',
faq_section: 'pricing_questions',
session_duration_sec: Math.round(performance.now() / 1000),
page_visit_count: 6
});Common Pitfalls
- Including too many steps or events in your path—GA4's visualization breaks down with more than 5–6 hops. Start narrow, then expand.
- Forgetting that Path Exploration only shows connected sequences. If you want to understand what happens before an event, you need to set that event as a step, not assume the path shows causation.
- Grouping by a dimension with too many values (like full page URL or custom user ID)—you'll get unreadable spaghetti. Use cleaner dimensions like page path or event name.
- Not setting a date range and traffic segment—Path Exploration on all traffic with no time filter can hide important patterns. Always filter to the relevant cohort or time period.
Wrapping Up
Path Exploration in GA4 transforms raw event data into visual journeys, showing you exactly how users move through your product. Use it to find drop-off points, validate that your navigation makes sense, and spot unexpected behavior patterns. If you want to track this automatically across tools, Product Analyst can help.
