Five Findings

Ranked by observable priority. Each finding includes the evidence Nebula used - no opinion, no estimation. Priority scores are rule-based heuristics for fix order, not predicted conversion loss.

Finding 1

Missing H1

Priority 5/10Quick Win

No H1 tag detected in static HTML. The primary headline is rendered via JavaScript, meaning search engines and link previewers that do not execute JS see no headline at all.

Evidence

Static HTML source: h1 count = 0. Headline content rendered client-side via JS bundle.

Recommended Fix

Server-render the primary headline as a static H1. This is the highest-signal on-page SEO element and should never be JS-dependent.

Finding 2

Page Payload

Priority 5/10Major Project

HTML payload is 1.2MB - 10× the 120KB heuristic. This is among the largest marketing homepages observed by the audit engine. Parse time, FCP, and LCP are all materially impacted.

Evidence

HTML payload: 1,228,000+ chars (~1.2MB). Heuristic max: 120KB. Delta: +1.08MB above ceiling.

Recommended Fix

Audit what is being server-rendered into HTML. Defer non-critical content. Move large data payloads (template lists, pricing tables) to API calls.

Finding 3

SEO Foundations

Priority 3.5/10Quick Win

Meta description is 161 chars - 6 chars over the ~155-char SERP truncation threshold. The tail end of the description will be cut off in most search results.

Evidence

meta description: 161 chars. SERP truncates at ~155. Last 6 chars cut from snippet.

Recommended Fix

Trim meta description to ≤155 chars. End on a complete thought.

Finding 4

Above-Fold Clarity

Priority 3/10Quick Win

Primary headline and CTA are JS-rendered. Source order does not reflect visual placement. Above-fold analysis requires rendered viewport inspection.

Evidence

Static source: no above-fold markers in first 3,000 chars. Headline and CTA loaded via JS bundle.

Recommended Fix

SSR the above-fold content. First 3,000 source chars should contain H1, primary CTA, and value signal.

Finding 5

Social Proof

Priority 2.5/10Quick Win

Trust language present in source ("enterprise", "teams", "integrations") but no named proof markers - no review count, no logo strip, no star rating - detected above fold.

Evidence

Trust terms: enterprise, teams, integrations. Named proof markers above fold: none.

Recommended Fix

Surface a concrete proof element at hero level: review count (Calendly has G2/Capterra reviews), customer count, or named logos.

What This Demonstrates

Calendly is a widely-used scheduling tool. A 5.8/10 captures five conditions - the missing H1 and payload issues are the most significant. Both are fixable without a visual redesign.
