How to Analyze A/B Test Results in Hotjar with Optimal UX Integration
Introduction
Combine the power of Hotjar's behavioral analytics with your A/B testing data from Optimal UX. This integration enables you to analyze user behavior recordings, heatmaps, and other visual insights specifically for different experiment variants, helping you understand not just what users do, but how they interact with your variants.
Why Use Hotjar for A/B Test Analysis?
Watch real user sessions for specific experiment variants
Create heatmaps segmented by experiment participation
Understand user behavior through visual analytics
Combine quantitative and qualitative insights
Get direct visual feedback on variant performance
Step-by-Step Integration Guide
Enable the Integration
Log into your Optimal UX dashboard
Navigate to Settings > Integrations
Locate the Hotjar integration card
Toggle the integration switch
Understanding Data Flow
When enabled, Optimal UX automatically sends experiment participation data to Hotjar as custom events:
Events are triggered using the Hotjar JavaScript API
Event names follow the format:
viewed_optux_[experiment slug]_[variant name]
Example: For an experiment with slug "xyz123" and variant "Variant B", the event would be
viewed_optux_xyz123_variant_b
Security Note: Optimal UX uses experiment slugs instead of full experiment names to ensure data security.
