## 1. Product Page Analysis (No DataForSEO Needed)

Fetch and parse any product page for on-page SEO quality.

### Workflow

```
1. python scripts/fetch_page.py <url>         → raw HTML
2. python scripts/parse_html.py --url <url>   → SEO elements
3. Analyze product-specific signals (below)
```

### Product SEO Checklist

- [ ] Format: `[Product Name] - [Key Feature] | [Brand]`

- [ ] Contains product keyword + benefit
- [ ] Includes price or "from $XX" (triggers rich snippet interest)

## 2. Google Shopping Intelligence (DataForSEO Merchant API)

Live competitive analysis from Google Shopping results.

### Cost Guardrail (MANDATORY)

Before EVERY Merchant API call:
```bash
python scripts/dataforseo_costs.py check merchant_google_products_search
```

- `"status": "approved"` -- proceed
- `"status": "needs_approval"` -- show cost, ask user
- `"status": "blocked"` -- stop, inform user

After each call:
```bash
python scripts/dataforseo_costs.py log merchant_google_products_search <cost>
```

### Workflow

```bash
# Product search: who sells what at what price
python scripts/dataforseo_merchant.py search "<keyword>" --marketplace google

# Seller analysis: merchant ratings and dominance
python scripts/dataforseo_merchant.py sellers "<keyword>"

# Normalize results for analysis
python scripts/dataforseo_normalize.py results.json --module merchant
```

### Analysis Outputs

#### Pricing Intelligence
- Price distribution: min, max, median, P25, P75
- Price outliers (> 2 standard deviations from median)
- Price-to-rating correlation
- Currency normalization to USD (or user-specified)

#### Seller Landscape
- Top 10 sellers by listing count
- Merchant rating distribution
- Free shipping prevalence
- New vs established sellers

#### Product Listing Quality
- Title keyword patterns in top listings
- Average rating and review count benchmarks
- Image count per listing
- Availability status distribution

## 3. Amazon Marketplace (DataForSEO)

Cross-marketplace intelligence comparing Google Shopping and Amazon.

### Cost Guardrail (MANDATORY)

```bash
python scripts/dataforseo_costs.py check merchant_amazon_products_search
```

Amazon endpoints are in the `warn_endpoints` set -- always requires user approval.

### Workflow

```bash
# Amazon product search
python scripts/dataforseo_merchant.py search "<keyword>" --marketplace amazon

# Cross-marketplace comparison
python scripts/dataforseo_merchant.py compare "<keyword>"
```

### Cross-Marketplace Report

| Metric | Google Shopping | Amazon |
|--------|---------------|--------|
| Avg price | $ | $ |
| Median rating | X.X | X.X |
| Avg review count | N | N |
| Top seller share | % | % |
| Free shipping % | % | % |

## 4. Marketplace Keyword Gaps

Identify mismatches between organic and Shopping visibility.

### Workflow

1. Fetch organic rankings via seo-dataforseo:
   `dataforseo_labs_google_ranked_keywords` for domain
2. Fetch Google Shopping presence via Merchant API:
   `merchant_google_products_search` for top organic keywords
3. Cross-reference results

### Gap Types

| Gap Type | Meaning | Action |
|----------|---------|--------|
| **Organic Only** | Ranks organically but no Shopping ads | Create Google Merchant Center feed, bid on these keywords |
| **Shopping Only** | Shopping visibility but weak/no organic | Create content (buying guides, comparison pages) for these keywords |
| **Both Present** | Visible in both channels | Optimize: ensure price consistency, enhance schema |
| **Neither** | No visibility in either | Low priority unless high volume |

### Output Format

```
## Keyword Gap Analysis: example.com

### Opportunities: Organic → Shopping (12 keywords)
| Keyword | Organic Pos | Volume | CPC | Recommended Action |
|---------|------------|--------|-----|-------------------|

### Opportunities: Shopping → Organic (8 keywords)
| Keyword | Shopping Rank | Volume | CPC | Content Type Needed |
|---------|-------------|--------|-----|-------------------|
