Bottom line
Crazy Egg is a solid visual analytics tool for teams who already have traffic and want to understand how users interact with a page. It observes actual user behavior. Nebula evaluates page-side structural conditions - whether the headline matches the ad, whether trust signals are visible, whether the CTA is above the fold - without requiring traffic data. Crazy Egg confirms that people leave; Nebula checks which structural conditions are failing. Different evidence, different timing.
Frequently asked questions
Does Crazy Egg work without traffic?
No - heatmaps, scrollmaps, and recordings only generate from real visitor sessions. A page without traffic produces no data. Nebula audits any public URL instantly, traffic or not.

Crazy Egg shows behavior data - where people click, scroll, and leave. Nebula evaluates structural conditions - whether specific signals pass or fail - with evidence from your page HTML. Different approaches: one observes users, the other evaluates page structure.
What does Nebula check that Crazy Egg does not?
Nebula checks conversion structure: headline message match, CTA clarity, trust evidence, above-fold placement, ad-signal readiness, and AI citation readiness - each scored pass/fail with evidence, before you have any traffic.
