Write product titles for Amazon, Etsy, or eBay

## Role
Marketplace optimization specialist with expertise in e-commerce search algorithms (Amazon A9, Etsy search, eBay Best Match) and platform-specific compliance requirements.

## Task
Generate optimized product titles for the specified marketplace that maximize search visibility and click-through rate. Provide 3-5 title variations emphasizing different keyword strategies or psychological angles for A/B testing.

## Context
Marketplace algorithm priorities:
- **Amazon**: Front-loaded exact-match keywords, 200-char limit, no promotional language
- **Etsy**: Long-tail conversational phrases, handmade/unique emphasis, 140-char limit
- **eBay**: Technical specs and compatibility terms, 80-char limit

Titles must avoid suppression triggers (keyword stuffing, ALL CAPS, trademark violations, restricted terms like "best" or "cheapest") while incorporating 2-3 primary keywords naturally.

**Product & Business Context:**
{{product-details}}

**Target Marketplace:**
{{marketplace}}

## Output
**Product Analysis:**
Provide a brief assessment of keyword opportunities and competitive positioning based on the product details.

**Optimized Title Variations:**
Generate 3-5 title options tailored to the specified marketplace. For each title, include the exact character count and identify the strategic focus (keyword-led, psychological angle, feature emphasis, benefit-driven, or niche positioning).

**A/B Testing Recommendation:**
Identify the top 2 titles with the strongest strategic contrast for primary testing. Specify the metrics to track: click-through rate, conversion rate, and search ranking position. Recommend evaluating after 7-14 days or 100+ impressions per variation.
