```

### Walmart (feature-focused, 150 chars each)
```
1. Made from 100% organic bamboo - naturally antimicrobial and knife-friendly, won't dull your kitchen knives like plastic boards.

2. Includes 3 cutting board sizes (Small 8x6, Medium 12x9, Large 16x12) - perfect for any kitchen prep task from herbs to roasts.

3. Deep juice grooves on all sides capture runoff from fruits, meats, and vegetables - keeps countertops clean during food prep.

4. Ergonomic side handles on each board for easy carrying and safe food transfer from cutting board to pot or serving dish.

5. Easy care: hand wash with mild soap or place in dishwasher (top rack). Oil occasionally with food-safe mineral oil.
```

## Avoiding Duplicate Content Penalties

### Cross-Platform Differentiation
```
Each platform should have UNIQUE content:

AMAZON: Focus on features, benefits, specifications
WALMART: Emphasize value, quality, problem-solving
eBay: Highlight condition, shipping, item specifics
ETSY: Tell the story, emphasize craftsmanship, uniqueness

SAME PRODUCT, DIFFERENT ANGLES:
- Amazon: "3 sizes for every kitchen task"
- Walmart: "The complete cutting board solution"
- eBay: "Professional-grade 3-piece set"
- Etsy: "Handcrafted eco-friendly kitchen essentials"
```

### Keyword Variation Strategy
```
Use different keyword variations per platform:

AMAZON: "bamboo cutting board set kitchen"
WALMART: "organic wood cutting boards 3 piece"
eBay: "bamboo chopping board kit professional"
ETSY: "sustainable cutting board eco-friendly gift"
```

## Platform-Specific Best Practices

### Amazon
```
DO:
✓ Start bullets with BENEFIT IN CAPS
✓ Use all 5 bullet points
✓ Include backend keywords (250 bytes)
✓ Fill all product attributes

DON'T:
✗ Use ALL CAPS for entire bullet
✗ Include pricing or promotions
✗ Use emojis or special characters
✗ Make subjective claims without proof
```

### Walmart
```
DO:
✓ Aim for 100/100 Content Quality Score
✓ Write 150+ word descriptions (unique!)
✓ Complete all relevant attributes
✓ Add Rich Media (video, 360° images)

DON'T:
✗ Copy content from Amazon listings
✗ Use fewer than 3 key features
✗ Skip attribute fields
✗ Ignore the Listing Quality Dashboard
```

### eBay
```
DO:
✓ Use all 80 characters in title wisely
✓ Complete ALL item specifics
✓ Include detailed condition description
✓ Format descriptions for mobile (short paragraphs)

DON'T:
✗ Use "WOW" or "BEST" in titles
✗ Leave item specifics blank
✗ Use hidden text or keyword stuffing
✗ Create clickbait titles
```

### Etsy
```
DO:
✓ Lead with primary keyword in title
✓ Use all 13 tags (long-tail variations)
✓ Write story-driven descriptions
✓ Emphasize handmade/unique angles

DON'T:
✗ Use generic AI-sounding copy
✗ Waste tags on single words
✗ Ignore the gift angle
✗ Skip the "why" behind your product
```

## Inventory Sync Considerations

```
When selling across platforms:

TOOLS: SellerChamp, Sellbrite, M2E Cloud, SureDone
- Real-time inventory sync prevents overselling
- Centralized order management
- Platform-specific content can still be unique

WARNING SIGNS:
- Same description everywhere = duplicate content risk
- Pricing inconsistency can violate marketplace policies
- Inventory discrepancies lead to cancellations
```
