How to Analyze Landing Page Tests in GA4 for WordPress (Explained)

To analyze landing page tests in GA4, open Reports >> Engagement >> Landing page, filter to your variant URLs, and compare Engagement Rate, Average Engagement Time, and Key Event Rate for each variant. Check the source/medium split first, so you know both variants received comparable traffic. 

If GA4 is not connected to your WordPress site yet, I recommend this guide first: How to Set Up Google Analytics 4 and Connect it to Your WordPress Site?.

This guide is for WordPress marketers and site owners who already run a landing page A/B test. I show how to compare your landing page variants in GA4, identify the winning version, and make data-driven decisions. 

I cover the Exploration report you need, the metrics that decide a winner, and how to see these insights without leaving your WordPress dashboard.

GA4 does not split traffic between variants, so run the test itself in a separate A/B testing tool and use GA4 to analyze the results.

What GA4 Can (and Can’t) Tell You About Landing Page Tests 

GA4 shows engagement, key event, and traffic source data for each variant URL, but it does not run the test or calculate statistical significance. Use that data to compare variants and decide based on actual user behavior.

GA4 is not a dedicated optimization platform; it won’t randomly assign users to groups or calculate statistics of your data natively. 

What GA4 Can Measure

GA4 shows how users interact with each version:

• Engagement Rate per URL: The percentage of sessions that were engaged. Bounce rate is the inverse of engagement rate.
• Average Engagement Time per Session: Discover if your new copy actually holds attention longer than the control.
• Key Event (Conversion) Count: The bottom-line number of successful actions taken on each variant.
• Traffic Source Breakdown: See if Variant A performs better for Meta Ads traffic while Variant B excels with organic search.
• New vs. Returning User Split: Understand if your changes appeal more to fresh leads or loyal followers.

What GA4 Cannot Do

GA4 won’t do the heavy lifting of experimental design. It cannot assign users to test groups or determine whether differences in conversion rates are meaningful.

For that, you must rely on your testing tool’s built-in statistical model. 

Important Accuracy Note: Remember that GA4’s engagement metrics are session-scoped. This means it measures sessions that started on a given landing page. If a user lands on your homepage and then navigates to a variant, those engagement metrics will be attributed differently. We will focus on “Landing Page” reports to ensure the data is as clean as possible.

The 4 GA4 Metrics That Actually Matter for Landing Page Test Analysis

Four GA4 metrics matter most for a landing page test: Engagement Rate, Average Engagement Time, Key Event Rate, and Session Source/Medium. The first three show how visitors behave on each variant, and Source/Medium shows whether the traffic was comparable:

1. Engagement Rate

The Engagement Rate is the percentage of sessions on each variant URL that resulted in meaningful interaction. 

In GA4, a session is engaged if it lasts longer than 10 seconds, has a key event, or has 2 or more page or screen views.

A higher engagement rate on a variant is a direct signal that visitors are more interested in what they are seeing. 

Benchmark context: Compare the variants against each other instead of an industry average. A consistent gap in engagement rate, with comparable traffic sources and sample size, is a signal worth acting on.

2. Average Engagement Time per Session

This metric measures how long visitors actively interact with your page. 

If a variant has a longer average engagement time, it usually means the layout is more intuitive, or the copy is more compelling, keeping visitors reading further down the funnel.

GA4 only counts active engagement time, meaning the browser tab was open and the user was actually interacting with the page. 

It ignores idle time, providing a much more honest look at your content’s performance.

3. Key Event (Conversion) Rate

This is your primary test outcome metric. GA4 calls it Session key event rate: the percentage of sessions in which a key event happened, such as a form submission or button click. 

This is the decisive metric that tells you which version is actually making you money.

Critical Prerequisite: For this to appear in your reports, you must first mark your conversion event as a key event. In GA4, go to Admin >> Data display >> Events and select the star icon next to the event. Without a key event, GA4 cannot calculate key event metrics for your test analysis.

4. Session Source/Medium Breakdown

Before you trust any of the metrics above, you must check your traffic sources. If your variants aren’t receiving similar traffic, your test is compromised. 

A variant that gets 90% of its traffic from high-intent Google Search will naturally outperform a variant that gets traffic from a disruptive Meta ad. This holds regardless of design. 

Always verify that the Source/Medium is balanced across both URLs before drawing conclusions.

GA4 Metric	What It Measures	What to Compare
Engagement Rate	Quality of visitor interest on landing	Higher = better variant experience
Avg Engagement Time	How long visitors actively engage	Higher = more compelling content
Key Event Rate	Conversion rate per variant	Primary outcome : the decisive metric
Source/Medium	Where traffic comes from per variant	Must be similar — verify this first

How to Find Landing Page Variant Data in GA4 (Step by Step)

To find landing page variant data in GA4, open Reports >> Engagement >> Landing page. Wait until your test has run for at least 2 weeks and each variant has 200+ sessions before you analyze it. These thresholds are a rule of thumb. 

Here are the exact steps to find and analyze landing page tests in GA4.

Step 1: Find Your Landing Pages Report

In the left-hand navigation of GA4, go to Reports >> Engagement >> Landing page. 

If you cannot find the Landing page report, it may have been removed or is not in your default view. Editors and above can add it back to the left navigation.

This report is essential because it isolates the pages where sessions actually began, ensuring you are looking at the entry point of your test.

Your two variant pages (e.g., /landing-page-v1/ and /landing-page-v2/) will appear in this list.

Step 2: Filter to Your Test URLs Only

To remove the noise of your other site pages, click the search/filter bar directly above the table. Use the filter Landing page + query string and set the condition to “contains” your variant URL path. 

The filter narrows the table to your two test pages side by side.

Step 3: Add the Metrics You Need

The default GA4 metrics for landing page tests might not show everything you need. If you have edit permissions, you can customize the report accordingly. 

Note: Under Metrics, ensure you add: Engagement Rate, Average Engagement Time, and Key Events. Save the report, and later on, you can edit it accordingly. 

These columns give you the behavioral data for each variant.

Step 4: Check Source/Medium Before Drawing Conclusions

Before you declare a winner, you must ensure the traffic was fair. Go to Reports >> Acquisition >> Traffic acquisition. 

Filter by the landing page for each variant URL separately. Confirm that both variants are receiving similar source/medium splits. 

If one variant has 80% paid traffic and the other has 80% organic, the test is not comparable, and the data is skewed.

Step 5: Use Exploration toAnalyze Landing Page Tests in GA4

For the cleanest split test landing page analytics, go to Explore >>  Blank exploration.

• Dimensions: Landing page + query string.
• Metrics: Sessions, Engagement Rate, Avg Engagement Time, Key Events.
• Filter: Your two variant URLs.

This exploration gives you a dedicated view of which variant performs better across all key metrics.

When to Call a Winner in Your Landing Page A/B Test (and When to Keep Running) 

Call a winner when one variant leads on Key Event Rate and Engagement Rate with comparable traffic sources, and your testing tool confirms the difference is significant. Your business objective decides which metric carries more weight. 

The metrics tell you what happened, but your goals determine which version actually won. 

Here is how to read and analyze landing page tests in GA4 and make a confident decision.

1. Clear Winner: Act Immediately

A clear winner emerges when one variant has a meaningfully higher Engagement Rate AND a higher Key Event Rate, provided the traffic sources are comparable. 

If one variant leads consistently for at least 2 weeks and your testing tool confirms the difference is statistically significant, you have a winner. 

Implement the winning variant fully to start reaping the benefits of the higher conversion rate.

Example Scenario: Variant B has a 68% engagement rate vs. Variant A’s 51%, and a 4.2% key event rate vs. 2.8%. Since the source/medium split is identical, Variant B is the objective winner.

2. Mixed Signals: Run Longer or Isolate the Variable

Sometimes, engagement rate favors one variant, but key event rate favors the other. Mixed signals usually mean one page is better at holding attention, perhaps with better copy or video content. The other page is more efficient at driving a direct action, perhaps with a more prominent CTA.

Decision: If your primary goal is lead generation or sales, Key Event Rate wins. If you are optimizing a resource page for brand awareness and content consumption, Engagement Rate wins. Clarify your objective before making the choice.

3. No Meaningful Difference: Test Something Bigger

If both variants show metrics within 5 percentage points of each other across all key indicators, the test is inconclusive. 

This means the change , such as a button color or a single word in a subheadline, was not important enough to change user behavior.

Don’t pick a winner out of impatience . Go back to the drawing board and test a “big swing”: a completely different headline, a new layout, or a different offer entirely.
