If you use GA4, you might already have done the work to track visitor conversions as “key events”. You can now track these events as Conversions in Crazy Egg, without adding new tags or code.

To track a “key event” in GA4 as a conversion in Crazy Egg:

Click “+ Track New Conversions” in Conversions, then give your conversion a name.

Select the “When someone triggers a GA4 event” option (pictured).

Provide your GA4 measurement ID.

Provide the Event Name of the GA4 event you want to track. This can be standard events like click or scroll, as well as custom events.

Tracking these gets more accurate conversion data in your Crazy Egg account, which helps you:

See which A/B Testing variant actually drives conversions, not just clicks
View Heatmaps segmented by converters vs. non-converters, so you see what page content actually drives conversions
Watch Recordings of visitors who converted, vs. those who didn’t
Trace the exact path that converting visitors took in Funnels

Crazy Egg can detect any GA4 conversion event, as long as the event is fired in the visitor’s browser. This includes common setup methods like a Google Tag, Google Tag Manager (GTM), and many Customer Data Platforms (CDPs). However, the event will not be detected if it’s only forwarded server-side or processed after it leaves the browser.
