If your page has a message-match failure or a weak CTA, Hotjar will show you people leaving. Nebula identifies the failing signal before they arrive.
Frequently asked questions
Does Hotjar require existing traffic?
Yes - heatmaps, recordings, and scrollmaps only generate from real visitor sessions. A new landing page with little traffic produces little data. Nebula audits any public URL immediately, with no traffic required.
Can Hotjar tell me why my page does not convert?
Hotjar shows behavior - where people click, scroll, and leave - but does not diagnose the cause. If the headline does not match the ad, Hotjar shows visitors leaving; Nebula names the message-match failure and the fix.
What is the difference between Hotjar and Nebula?
Hotjar is a post-launch behavior tool (heatmaps, recordings, surveys) that needs traffic and time. Nebula is a pre-conversion diagnostic that scores the page's conversion structure - message match, CTA, trust, above-fold - before you burn ad spend.
