How to Measure Free Sample Success Rate in GA4 (Two-Step Funnel Method)

Описание: Trying to measure conversion rate in GA4 but struggling to get a clear, actionable report? In this video, I’ll show you one of the most useful (and most overlooked) techniques in Google Analytics 4: the GA4 Two-Step Funnel.

A two-step funnel is an “if this, then that” method inside GA4 Funnel Exploration—you define one key action (input) and measure whether it leads to a desired outcome (conversion). This is one of the cleanest ways to understand GA4 funnel conversion rate, validate performance, and spot issues like low-quality traffic or bot activity that can distort your numbers.

✅ What you’ll learn in this GA4 conversion rate tutorial

How to build a Two-Step Funnel in GA4 (Funnel Exploration)
How to measure GA4 conversion rate using real user actions
How to track Free Sample → Paid Purchase conversions (purchase value = 0 → purchase value ≠ 0)
How to measure View Item → Purchase conversion rate (PDP conversion rate)
How to analyze PLP → PDP conversion rate (collection/category pages → product pages)
How to break funnels down by key dimensions like:
Landing page (landing page conversion rate in GA4)
Source / campaign (campaign conversion rate in GA4)
How to use segments to combine insights (example: channel + age)
How to identify data pollution (example: bot traffic dominating a city breakdown with zero completions)
How to filter funnels to only include product pages for accurate ecommerce analysis

🔍 Why Two-Step Funnels are powerful in GA4

GA4 conversion metrics can be confusing because the “right” conversion rate depends on scope and context. Two-step funnels make it simple:
pick one meaningful input event (like view_item, free sample purchase, PLP view)
pick one outcome (like purchase, add_to_cart, PDP view)
measure completion rate + compare performance across landing pages, campaigns, and segments

This helps you find what actually drives revenue—and what’s wasting traffic.
