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:

Captures your product DNA - Extracts core positioning, target audience, and differentiation
Generates initial copy - Creates 7 critical website sections (hero, problems, solution, benefits, social proof, FAQ, CTA)
Runs hostile validation - Tests copy against 5 skeptical visitor personas using 25 validation angles
Rebuilds with objection immunity - Fixes critical conversion killers and credibility gaps
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:

Product description - What your product is and does
Problem it solves - The specific pain point (not generic category)
Target audience - Psychographics more than demographics
Differentiation - What actually makes it different
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]

The Validation Process (Behind the Scenes)

Your copy is tested against 5 hostile visitor personas:

The 8-Second Scanner - Will they immediately bounce?
The Comparison Tab Hoarder - Why would they choose you vs competitors?
The Burned Cynic - What triggers their BS detector?
The Confused Bouncer - What's unclear or confusing?
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
