### Keyword Analysis

**For Each Major Keyword**:
1. **Search volume**: Is it commonly searched?
2. **Competition**: How many other sellers use it?
3. **Relevance**: Does it accurately describe your product?
4. **Specificity**: Is it too broad or too narrow?

**Keyword Categories**:

| Type | Examples | Use |
|------|---------|-----|
| **Product Type** | ball valve, circuit breaker, LED panel | Primary keyword in title |
| **Material** | stainless steel, aluminum, PVC | In title + description |
| **Application** | industrial, plumbing, automotive | In description |
| **Specification** | DN50, 12V, 100W | In title (if space allows) |

### Product Description Analysis

**Check for**:
- Clear product features and specifications
- Product benefits (not just features)
- Technical parameters (dimensions, materials, certifications)

## Phase 5: Keyword Strategy

### Keyword Research Process

1. **Seed keywords**: Start with main product terms
2. **Expand**: Add variations (synonyms, related terms)
3. **Filter**: Remove irrelevant or extremely low-volume terms
4. **Prioritize**: Focus on high-relevance + moderate-competition terms

### Keyword Categories for B2B

| Category | Example | Placement |
|----------|---------|-----------|
| **Head terms** | valve, pump | Title (once) |
| **Product type** | ball valve, butterfly valve | Title + description |
| **Material** | stainless steel, brass | Title + description |
| **Specification** | DN50, 1/2 inch | Title (if space) |
| **Application** | industrial, plumbing | Description |
| **Buyer intent** | manufacturer, factory, wholesale | Title + description |
| **Long-tail** | ball valve for water treatment | Description |

### Title Optimization Rules

1. **First 30 characters matter most** — put primary keyword here
2. **Include product type** — what are you selling?
3. **Add key spec if space** — material, size, or model
4. **Include buyer intent keyword** — manufacturer, wholesale
5. **Don't stuff** — 3-5 keywords max in title
6. **Match search terms** — think like your buyer

## Quality Standards

1. **Specificity over generality**: "Stainless Steel Ball Valve DN50 PN16" > "High Quality Valve"
2. **Buyer-centric**: Focus on benefits to the buyer, not just features
3. **Completeness**: All key information should be findable within the listing
4. **Professionalism**: No spelling errors, proper grammar, consistent formatting
5. **Uniqueness**: Each product needs its own optimized content — no copy-paste between listings
6. **Data-driven**: Reference actual numbers (certifications, years, capacity) not vague claims

## Common Pitfalls

1. **Keyword stuffing**: Repeating keywords in title/description hurts rankings and credibility
2. **Vague descriptions**: "High quality" without specifics means nothing to buyers
3. **Missing trade terms**: Always include MOQ, lead time, payment terms
4. **Poor images**: Dark, blurry, or unprofessional photos kill inquiries
5. **Copying competitors**: Learn from them, but differentiate your content
6. **Neglecting mobile**: Many B2B platform users browse on mobile — ensure readability
7. **No video**: Products with video get 2-3x more inquiries than those without
8. **Ignoring data**: Use platform analytics to understand what's working
