Landing Page Doctor

A Claude Code skill that diagnoses Landing Page first-screen (above the fold) conversion problems and provides actionable rewrite suggestions.

Give it any URL, get a structured 10-point diagnostic report with scores and specific improvements.

What It Does

Captures desktop + mobile screenshots and extracts page data (headlines, CTAs, trust signals, etc.)
Classifies page type (Indie SaaS / B2B / E-commerce / Content) and brand maturity
Diagnoses against 10 objective checkpoints across 4 categories
Interprets scores in context — the same score means different things for a known brand vs a new indie project
Outputs a structured report with specific rewrite suggestions

The 10 Checkpoints

Category	#	Checkpoint	Max
A. Value Communication	1	Headline Value Proposition	10
	2	5-Second Clarity	10
	3	First-Screen Information Density	10
B. Action Guidance	4	CTA Visibility	10
	5	CTA Copy Quality	10
	6	Commitment Reduction	10
C. Trust Building	7	Trust Anchor Presence	10
	8	Trust Authenticity	10
D. Technical Performance	9	Mobile Responsiveness	10
	10	Copy Readability	10
Total			100

Each checkpoint uses **objective feature detection** (Y/N checks) rather than subjective judgment, ensuring consistent results across different AI models.
