Nebula

Nebula is a free, evidence-backed landing page audit that shows you what your page is doing, what conditions are failing, and what to change. Enter a URL and Nebula evaluates the page across nine signals covering messaging, calls to action, trust and social proof, mobile experience, performance, SEO, AI readiness, and other conditions that can affect the quality of a landing-page experience. Findings aren't just scores or generic recommendations. Each determination is tied to observable evidence from the audited page. Where applicable, Nebula shows the condition being evaluated, what was observed, the threshold used, where the issue was found, and the recommended change. What you get: • A complete landing page audit • PASS, FAIL, or INDETERMINATE determinations backed by page evidence • Prioritized findings based on condition severity and remediation effort • A “Fix first” recommendation explaining why that condition was prioritized • Actionable remediation guidance for failed conditions • Paste-ready copy, HTML, or configuration when an exact implementation can be generated • Mobile viewport, performance, SEO, and AI-readiness checks • Re-auditing to verify whether audited conditions changed Nebula was initially built around paid-traffic landing pages, where weak page conditions are especially expensive because every visit has a direct acquisition cost. Most of the audit, however, applies equally to organic, social, referral, and other traffic sources. Checks requiring advertising or source context are handled separately rather than treating missing context as a failure. Nebula deliberately does not claim that changing a failed condition will increase conversions. A re-audit can establish that the page changed and that the same condition moved from FAIL to PASS. Whether that change improves conversion performance is a separate question that requires outcome data. The audit is free. For teams that want help implementing the highest-priority remediation, Nebula also offers a scoped $97 Repair Sprint.
