Nebula Components
What is Nebula Components?
Nebula Components is an evidence-based landing page diagnostic for founders spending on paid ads with low or zero conversions.
Submit a URL and an automated audit checks the page against nine conversion signals with published decision rules. Every failing condition comes back as a finding with measured evidence from your actual page: what was observed, what the rule requires, and the gap. The diagnosis is free and ungated. The repair is a fixed-price $97 sprint on one finding. No calls, no retainers, no performance theater.
How it works
- Submit your landing page URL. No account needed.
- The engine inspects raw HTML and rendered output at desktop and mobile widths.
- Nine signals are evaluated against the public specification.
- You get a score, ranked findings, and per-finding evidence before giving an email.
- Email unlocks the full report. If you want a fix, the Repair Sprint is $97 flat.
Who it is for
Founders actively spending on Google, Meta, or LinkedIn ads whose pages are not converting. The trigger is spending without converting, not company size or industry.
The methodology is public
Unlike tools that keep scoring criteria hidden, Nebula publishes exactly what the audit checks. The Landing Page Diagnostic Specification v1 defines every signal's decision rule, severity bands, and the evidence record attached to each finding. It is versioned, machine-readable, and citable with attribution.
Published benchmark
In Nebula's July 2026 cross-industry study of 86 landing pages running paid traffic, the average score was 62.7/100 (Grade C). Per-signal failure rates and score distribution are published at /benchmarks and computed only from completed audits. You may quote these figures with attribution to Nebula Components.
What Nebula is not
- Not a page builder. Nebula diagnoses; you keep your stack.
- Not an analytics dashboard. Findings come from inspecting your page, not tracking pixels.
- Not a guarantee machine. Findings identify repair candidates; they do not promise lift.
- Not a retainer. One page, one finding, one bounded repair, done.
The fastest way to understand Nebula is to run it on your own page.
