Sales Page Copywriting - Claude Skill

Battle-tested sales page copy generation using hostile validation methodology

Generate conversion-optimized sales page copy that survives scrutiny from 5 hostile visitor personas across 25 validation angles. No guesswork—only polished, ready-to-implement copy.

What It Does

Sales Page Copywriting is a Claude skill that:

  1. Captures your product DNA - Extracts core positioning, target audience, and differentiation
  2. Generates initial copy - Creates 7 critical website sections (hero, problems, solution, benefits, social proof, FAQ, CTA)
  3. Runs hostile validation - Tests copy against 5 skeptical visitor personas using 25 validation angles
  4. Rebuilds with objection immunity - Fixes critical conversion killers and credibility gaps
  5. Outputs polished copy - Delivers final, battle-tested website copy ready for implementation

You receive: A complete website copy document with hero section, problem agitation, solution steps, benefits with proof, social proof templates, FAQ, and final CTA—all validated and optimized.

You don't see: The internal validation process, hostile reviewer feedback, or iteration cycles. Only the final polished output.

Usage

In Claude CLI or Claude.ai

/sales-page-copywriting

Claude will then guide you through providing:

  1. Product description - What your product is and does
  2. Problem it solves - The specific pain point (not generic category)
  3. Target audience - Psychographics more than demographics
  4. Differentiation - What actually makes it different
  5. Conversion goal - What action you want visitors to take

Example Session

User: /sales-page-copywriting

Claude: I'll help you generate battle-tested sales page copy. Let me gather some information about your product.

**What is your product/service?** (Describe it in one sentence)

User: An AI tool that finds validated product ideas by analyzing real customer pain points across Reddit, Twitter, and forums

Claude: Got it. Let me ask a few more questions...

[Claude asks clarifying questions]

[Claude works internally through validation]

[Claude outputs final polished copy document]

What You Get

The final output includes:

1. Strategic Foundation

  • Core product DNA
  • Market context and competitors
  • Common objections identified

2. Complete Website Copy

  • Hero Section: Headline, subheadline, CTA, visual direction
  • Problem Agitation: 3-4 pain points with emoji bullets in customer voice
  • Solution Introduction: How it works in 3-4 simple steps
  • Benefits: 3 transformation-focused benefits with micro-proof
  • Social Proof: Positioning statement + 3 testimonial types + trust indicators
  • Objection Handling: 5-6 pre-emptive FAQ answers
  • Final CTA: Urgency mechanism + risk reversal + CTA copy

3. Validation Summary

  • Number of objections found and fixed
  • Critical failures addressed
  • High-priority improvements made
  • Approval metrics

4. Implementation Guidance

  • A/B test variations to try
  • Mobile optimization hierarchy
  • Visual priority sections
  • Tone/voice guidelines
  • Character counts for design

The Validation Process (Behind the Scenes)

Your copy is tested against 5 hostile visitor personas:

  1. The 8-Second Scanner - Will they immediately bounce?
  2. The Comparison Tab Hoarder - Why would they choose you vs competitors?
  3. The Burned Cynic - What triggers their BS detector?
  4. The Confused Bouncer - What's unclear or confusing?
  5. The Justified Procrastinator - What lets them delay action?

Each persona analyzes through 5 layers:

  • Clarity failures
  • Relevance rejections
  • Credibility collapse
  • Friction discovery
  • Competitive disadvantages

= 25 validation angles (5 personas × 5 layers)

The skill identifies Critical Failures (3+ reviewers object) and High Priority issues (2+ reviewers object), then rebuilds the copy until approval criteria are met.

Format Features

  • Emoji pain points - Uses 😤, 😫, 🤯, 😰 in problem agitation
  • Customer voice quotes - Pain points written as internal dialogue
  • Micro-proof for every claim - No unsubstantiated benefits
  • Conversational FAQ - Not corporate speak
  • Honest urgency - No fake scarcity
  • Validation transparency - Shows the rigor behind the copy
