Context Guard

Context	Status
User says "product description", "product listing", "product copy"	ACTIVE
User says "Amazon listing", "Shopify listing", "e-commerce copy"	ACTIVE
User wants to write or improve copy for a product listing	ACTIVE
User wants to set pricing	DORMANT — use Pricing Strategy
User wants a full sales funnel	DORMANT — use Sales Funnel

Common Mistakes

Mistake	Why It's Wrong
"List features, not benefits"	"500mAh battery" means nothing. "Lasts 12 hours so you never run out mid-day" sells.
"Generic descriptions"	"High quality product" could describe anything. Be specific about WHAT makes it quality.
"Ignore the platform"	Amazon, Shopify, and Etsy have different algorithms, formats, and buyer expectations.
"No keywords"	E-commerce search is keyword-driven. No keywords = invisible in search results.
"One version only"	A/B testing descriptions is easy and can improve conversion 10-30%. Write variants.

Protocol

Step 1: Gather Product Details

If the user hasn't provided details, ask:

1. Product — what is it? (name, category, physical/digital)
2. Features — what are its key specs and features? (list 5-10)
3. Audience — who buys this? (demographics, use case, pain point)
4. Platform — where is it listed? (Amazon, Shopify, Etsy, other)
5. Price point — what does it cost? (affects copy tone and positioning)
6. Competitors — what are the top 3 alternatives? (for differentiation)

Step 2: Feature-to-Benefit Conversion

Transform every feature into a customer benefit:

Feature (What It Is)	Benefit (Why They Care)	Emotional Trigger
[Technical spec]	[Practical outcome]	[Feeling it creates]

Examples:

Feature	→ Benefit	→ Emotional
"Made from organic cotton"	"Gentle on sensitive skin"	"Safe for your baby"
"5000mAh battery"	"Lasts 2 full days on one charge"	"Never stress about dying battery"
"Adjustable height: 28-36 inches"	"Fits any desk setup, standing or sitting"	"Work comfortably, your way"
"Ships in recyclable packaging"	"Zero waste delivery to your door"	"Feel good about your purchase"

Conversion formula:

[Feature] → so you can → [Benefit] → which means → [Emotional outcome]

Step 3: Write the Product Description

Universal structure:

## [Product Title — Keyword-Rich, Benefit-Driven]

### Opening Hook (1-2 sentences)
[Address the pain point or desire. Create an "I need that" reaction.]

### Key Benefits (bullet points)
• [Benefit 1] — [supporting detail]
• [Benefit 2] — [supporting detail]
• [Benefit 3] — [supporting detail]
• [Benefit 4] — [supporting detail]
• [Benefit 5] — [supporting detail]

### Body Description (2-3 short paragraphs)
[Paint a picture of using the product. Use sensory language.
Address the top objection. Include social proof if available.]

### Specifications
[Technical details for comparison shoppers]

### Call to Action
[Urgency or reassurance: "Order now" + guarantee or shipping info]

Sensory language guide:

Sense	Words	Use For
Touch	Silky, rugged, lightweight, cushioned, velvety	Clothing, furniture, tools
Sight	Vibrant, sleek, crystal-clear, polished, matte	Electronics, decor, fashion
Sound	Whisper-quiet, crisp, deep bass, silent	Electronics, appliances
Taste	Rich, smooth, zesty, creamy, bold	Food, beverages
Smell	Fresh, earthy, aromatic, clean, invigorating	Candles, skincare, food

Step 4: Platform-Specific Formatting

Amazon listing format:

## Product Title (200 characters max)
[Brand] [Product Name] — [Key Benefit] [Key Feature] [Size/Variant] — [Use Case]
Example: "EcoBottle Premium Insulated Water Bottle — Keeps Drinks Cold 24 Hours — BPA-Free Stainless Steel, 32oz — Perfect for Hiking & Gym"

## Bullet Points (5 bullets, 200 chars each)
• [BENEFIT IN CAPS] — [Explanation]. [Spec detail].
• [BENEFIT IN CAPS] — [Explanation]. [Spec detail].
• [BENEFIT IN CAPS] — [Explanation]. [Spec detail].
• [BENEFIT IN CAPS] — [Explanation]. [Spec detail].
• [BENEFIT IN CAPS] — [Explanation]. [Spec detail].

## Product Description (2000 chars max)
[Rich HTML-formatted description with headers, paragraphs, and bold text]

## Backend Keywords (250 bytes)
[Hidden keywords separated by spaces — no commas, no repeats, no brand names]

Shopify product page:

## Product Title
[Concise, descriptive, SEO-friendly — 60-70 characters]

## Price + Compare-at Price (if on sale)

## Short Description (visible above the fold)
[2-3 sentences: hook + primary benefit + social proof snippet]

## Full Description (tabbed or expandable)
### Why You'll Love It
[3-5 benefit bullets]

### How It Works
[Use case description or instructions]

### What's Included
[List of everything in the box/package]

### Specifications
[Technical details table]

## SEO
- Meta title: [Product] — [Benefit] | [Brand] (60 chars)
- Meta description: [Compelling summary with CTA] (155 chars)
- URL handle: /products/[keyword-slug]

Etsy listing:

## Title (140 characters)
[Keywords first: "Handmade [Product] for [Occasion] — [Key Feature] [Material] [Size]"]

## Description (first 160 chars appear in search)
[Hook sentence first — this shows in search preview]
[Full description with story element — why you made this, materials used, care instructions]
[Size guide / dimensions]
[Shipping information]
[Care instructions]
[Customization options]

## Tags (13 tags, 20 chars each)
[Long-tail keywords that match buyer search behavior]
[Focus on: material, use case, recipient, occasion, style]

## Attributes
[Fill ALL available attributes — material, color, occasion, style]

Step 5: SEO Keyword Integration

Keyword research for product listings:

Keyword Type	Where to Use	Example
Primary keyword	Title, first sentence of description	"insulated water bottle"
Secondary keywords	Bullet points, body description	"BPA-free", "stainless steel", "cold 24 hours"
Long-tail keywords	Backend/tags, lower in description	"best water bottle for hiking 2026"
Competitor keywords	Backend/tags	"hydroflask alternative", "yeti competitor"

Keyword placement rules:

• Primary keyword appears in: title, first bullet/sentence, one subheading
• Don't keyword-stuff — read it aloud; if it sounds robotic, rewrite
• Backend keywords (Amazon) or tags (Etsy) are invisible — use them for synonyms and misspellings
• Use natural language — "water bottle that keeps drinks cold" beats "cold water bottle insulated"

Step 6: Write A/B Variants

Write 2 description variants to test:

## Variant A: Benefit-Led
[Opens with the primary benefit and emotional outcome]
"Never worry about your drink going warm again. The [Product] keeps
beverages ice-cold for 24 hours..."

## Variant B: Problem-Led
[Opens with the pain point the product solves]
"Tired of lukewarm water halfway through your hike? [Product] uses
double-wall vacuum insulation to keep your drinks cold all day..."

What to A/B test:

• Headline approach (benefit-led vs. problem-led)
• Bullet point order (most popular benefit first vs. most unique)
• Description length (short punchy vs. detailed comprehensive)
• CTA text ("Add to Cart" vs. "Get Yours Now" vs. "Buy Now — Free Shipping")

Step 7: Pre-Publish Checklist

• Primary keyword in title and first sentence
• All features converted to benefits (no naked specs)
• Sensory language used where appropriate
• Platform-specific format followed (Amazon bullets, Shopify tabs, Etsy story)
• Backend keywords / tags filled in
• Images referenced match description claims
• Price and shipping info are accurate
• Social proof included if available (reviews, awards, "bestseller")
• Scannability: bullets, bold, short paragraphs
• Read aloud — does it sound natural and persuasive?
• Mobile preview checked (most shopping is mobile)
