Common Mistakes

MistakeWhy 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:

SenseWordsUse For
TouchSilky, rugged, lightweight, cushioned, velvetyClothing, furniture, tools
SightVibrant, sleek, crystal-clear, polished, matteElectronics, decor, fashion
SoundWhisper-quiet, crisp, deep bass, silentElectronics, appliances
TasteRich, smooth, zesty, creamy, boldFood, beverages
SmellFresh, earthy, aromatic, clean, invigoratingCandles, 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 TypeWhere to UseExample
Primary keywordTitle, first sentence of description"insulated water bottle"
Secondary keywordsBullet points, body description"BPA-free", "stainless steel", "cold 24 hours"
Long-tail keywordsBackend/tags, lower in description"best water bottle for hiking 2026"
Competitor keywordsBackend/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)

Output Format

## Primary Keyword: [Keyword]

### Title
[Platform-optimized title]

### Description
