Nebula
Audits a landing page against 9 measurable signals and shows the raw evidence
Runs a free audit against 9 measurable signals — message match, CTA clarity, above-fold clarity, trust-proof placement, load speed, mobile viewport, ad tracking, SEO and AI readiness — each returning a pass/fail line with the actual measured value against a published threshold, for example a CTA sitting at 1,022px against an 812px target. Draws on 293 completed audits to publish recurring failure rates: 62% headline mismatch, 40% mobile CTA buried, 39% no trust proof near the CTA. Runs in under 2 minutes with no signup; a $97 "Repair Sprint" covers fixing the leaks it finds.
What holds up
- +Every failure shows the measured value against a published pass threshold, e.g. CTA at 1,022px vs an 812px target
- +Publishes recurring failure rates across 293 real audits — 62% headline mismatch, 40% mobile CTA buried
- +Free audit runs in under 2 minutes with no signup
Mind the limits
- −Fixing the leaks found costs $97 for the "Repair Sprint" — the free part is diagnosis only
- −Checks only 9 fixed signals, so issues outside that list go unmeasured
