Crazy Egg heatmaps
Crazy Egg is a website-optimization tool best known for heatmaps — click, scroll, and movement overlays — plus snapshots and basic A/B testing. It samples visitor interaction to show where attention and clicks concentrate. This page describes its data model and privacy posture even-handedly, without ranking it against other behavior tools.
What this means
Crazy Egg records where visitors click, how far they scroll, and where pointers move, then renders these as heatmap overlays and 'snapshots' on a screenshot of the page.
Beyond heatmaps it offers click reports and lightweight A/B testing, so it sits in the behavior-and-optimization category rather than core traffic counting.
Data model and posture
The captured data is interaction coordinates and scroll depth tied to a page and viewport, aggregated across sessions into overlays rather than analyzed as individual journeys.
Because capture happens on the page, it can incidentally observe interaction near input fields, so masking and configuration determine what is collected. The privacy posture depends on those settings and on applicable rules.
- Click, scroll, and movement heatmaps
- Snapshots over a page screenshot
- Aggregated overlays, not individual journeys
- Input masking shapes what is captured
How it appears in analytics and logs
Crazy Egg on a page means an interaction-capture script is recording click and scroll coordinates to build heatmap overlays, so its output is aggregated attention, not individual identity tracking.
Diagnostic use case
Use Crazy Egg to see aggregated click, scroll, and attention patterns on a page so you can judge whether key content and calls to action sit where visitors actually interact.
What WebmasterID can help detect
WebmasterID measures traffic and events; Crazy Egg adds an on-page interaction overlay, describing a different layer than WebmasterID's counts.
Common mistakes
- Reading a heatmap as causation rather than an attention pattern.
- Failing to mask sensitive form fields before capture.
- Comparing heatmap samples directly to full traffic counts.
Privacy and accuracy notes
Interaction capture can incidentally record activity over form fields, so masking sensitive inputs matters. This is educational, not legal advice.
