name	copy-split-test
description	Run a ProductPinion Text Split Test on 3-5 title or first-bullet variations to find which copy drives clicks/comprehension before launching to Amazon MYE. Use when running `copy-split-test {ASIN}` or when copy variations need shopper validation.

copy-split-test — Pre-MYE Copy Validation

ProductPinion's Text Split Test compares 2-5 copy variations and gathers shopper preference + reasoning.

Prerequisites

• ProductPinion MCP
• 3-5 copy variations to test (titles, bullets, descriptions, A+ headlines)

Invocation

copy-split-test {ASIN} --type=title --variants={path-or-list}
copy-split-test {ASIN} --type=bullet --slot=1
copy-split-test {ASIN} --type=aplus-headline
copy-split-test {ASIN} --shoppers=100

Output

/tmp/cro-content/{ASIN}-copy-{type}-{date}.md

Phase 1 — Source Variants

Variants can come from:

• User-provided list / file
• Output of anthropic-skills:amazon-title-bullet-optimization
• Existing copy + 2-3 generated alternatives via Claude (using research-brief constraints)

Mandatory: every variant has the same constraint — 200 chars title (Amazon allows up to 200), or single bullet, or single A+ headline. Don't compare title vs bullet (different jobs).

Phase 2 — Configure Pinion Test

Test type: Pinion Polls → Text Split Test

Setup:

• Question by type:
  • Title: "Which title would you most likely click on Amazon?"
  • Bullet: "Which bullet point most makes you want to buy?"
  • A+ headline: "Which headline best describes the product?"
• Variants: 2-5 (3-5 recommended)
• Sample: 100 per variant
• Audience: research-brief

Phase 3 — Analyze

Per variant:

• % preference
• Why themes (clustered)

Phase 4 — Output

# Copy Split Test — {ASIN} ({type})

**Sample:** {N} | **Date:** {date}

## Variants

| Variant | Text | % Preference |
|---------|------|--------------|
| A | "{Variant A copy}" | 38% 🥇 |
| B | "{Variant B copy}" | 28% |
| ... | ... | ... |

## Why Variant A Won

- "More specific" (32% mentioned)
- "Easier to scan" (24%)
- ...

## Recommendation

✅ Ship Variant A to MYE for title test
OR ⚠️ Top 2 are within margin — iterate / merge their best elements
