How to Install PostHog with Google Tag Manager (Best GA4 Alternative for Experiment Tracking)

In this video, you’ll learn how to install PostHog using Google Tag Manager.
PostHog is the best free alternative to GA4 for tracking website analytics and A/B test results.

At Confident Story, we use PostHog because GA4 has serious limitations for experimentation, especially thresholding, which hides conversion data when volumes are low.

PostHog doesn’t suffer from this problem, and it’s free for up to 1,000,000 events per month, making it perfect for websites with small or medium traffic.

In this step-by-step tutorial, you’ll learn:
Why GA4 is not reliable for A/B test conversions
Why PostHog is a better fit for experimentation
How to create a PostHog account
How to install the PostHog tracking snippet in Google Tag Manager
How to configure consent (analytics_storage)
How to set tag firing priority correctly
How to verify installation using GTM Preview Mode
How to access Web Analytics & Product Analytics inside PostHog

This walkthrough pairs perfectly with GTMsplit™, because both tools follow the same philosophy:
