3. Analyze product-specific signals (below)

Cost Guardrail (MANDATORY)

Before EVERY Merchant API call:

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:

python scripts/dataforseo_costs.py log merchant_google_products_search <cost>

Workflow

# 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

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 |
|---------|-------------|--------|-----|-------------------|

Cross-Skill Integration

Skill	Integration Point
seo-schema	Delegates Product schema generation; reuses validation logic
seo-images	Product image audit (alt text, format, dimensions) — plus DigitalSourceType: TrainedAlgorithmicMedia IPTC label for AI-generated product images (Merchant Center requirement)
seo-content	Product description E-E-A-T and uniqueness analysis
seo-dataforseo	Organic keyword rankings for gap analysis
seo-technical	Core Web Vitals for product pages (LCP on hero image)
seo-google	Google Merchant Center feed validation via GSC

UCP — Universal Commerce Protocol (forward-looking)

Google-led standard (co-developed with Shopify, Etsy, Walmart, Wayfair, Visa, Mastercard, etc.) for letting AI agents discover, negotiate, and transact with merchants without one-off integrations. Already powers direct buying from AI Mode and Gemini.

Merchants already on Google Merchant Center with clean Product schema can declare a UCP profile at /.well-known/ucp listing capabilities (dev.ucp.shopping.checkout, .fulfillment, .discount). See references/ucp-universal-commerce-protocol.md for audit criteria, capability examples, and the relationship to AP2 (Agent Payments Protocol).

Audit command

# Discover and validate the UCP profile
python scripts/ucp_check.py https://store.example.com --json

# With endpoint reachability probes (HEAD each declared capability)
python scripts/ucp_check.py https://store.example.com --probe-endpoints --json

The script returns: profile presence, version, declared capabilities, structural issues (missing fields, unknown capability IDs), and (with --probe-endpoints) per-endpoint reachability. SSRF-blocked endpoints are reported explicitly. Missing profile is reported as opportunity, not failure — UCP adoption is early.
