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

1. Fetch Google Shopping presence via Merchant API:

merchant_google_products_search for top organic keywords

1. 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 |
|---------|-------------|--------|-----|-------------------|

5. Product Schema Enhancement

Validate and generate Product schema following Google's current requirements.

Confirmed Required Properties (Google Merchant)

Confirmed required fields are name, image, and offers; use Offer, not AggregateOffer, for merchant listings.

{
  "@context": "https://schema.org",
  "@type": "Product",
  "name": "",
  "image": [""],
  "offers": {
    "@type": "Offer",
    "url": "",
    "priceCurrency": "USD",
    "price": "0.00",
    "availability": "https://schema.org/InStock"
  }
}

Recommended Properties (Enhance Rich Results)

• sku -- product identifier
• description, brand, offers.seller -- recommended context fields
• gtin13 / gtin14 / mpn -- global trade identifiers
• aggregateRating -- star rating + review count
• review -- individual reviews (minimum 1)
• color, material, size -- variant attributes
• shippingDetails -- ShippingDetails with rate and delivery time (merchant-level shipping via ShippingService is also supported; shipping/returns can be set in Search Console without a Merchant Center account)
• hasMerchantReturnPolicy -- MerchantReturnPolicy with type and days
• hasAdultConsideration -- required for adult-oriented products (added 2026-05-20 to Product variant / Merchant listing); Google Search supports only the value https://schema.org/SexualContentConsideration
• category -- Text, CategoryCode, or an array mixing both. Use custom

text for merchant-defined product types and CategoryCode with Google's

taxonomy URL plus codeValue for Google Product Categories.

Validation Rules

1. price must be a number string, not "$29.99" (no currency symbol)
2. availability must use full Schema.org URL enum
3. image should be array with >= 1 high-res image URL
4. priceCurrency must be ISO 4217 (USD, EUR, GBP)
5. If brand is present, brand.name must not be empty or "N/A"
6. Sale periods use validFrom plus either validThrough or

priceValidUntil, in ISO 8601 format. Include time and timezone when known.

1. If aggregateRating present: ratingValue and reviewCount required
2. Do not include fake reviews or undisclosed incentivized reviews in visible

content or structured data. Clearly and prominently disclose incentives.

Schema Scoring

| Completeness | Score |

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

| All required fields | 50/100 |

| + aggregateRating | 65/100 |

| + sku/gtin/mpn | 75/100 |

| + shippingDetails | 85/100 |

| + merchantReturnPolicy | 90/100 |

| + reviews (3+) | 100/100 |

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 | GSC indexation + Performance data for product URLs (NOT Merchant Center feed validation, that is done in Merchant Center / the Merchant API; the legacy Content API for Shopping sunsets 2026-08-18) |

UCP: Universal Commerce Protocol (live)

Google-initiated open standard (co-developed with Shopify, Etsy, Wayfair,

Target, Walmart; payment partners Visa/Mastercard/Stripe/Adyen/Amex) for

letting AI agents discover, negotiate, and transact with merchants without

one-off integrations. Google confirms a first reference implementation for

conversational buying in AI Mode in Search. Broader Universal Cart rollout

details are reported from Google I/O 2026 keynote coverage; not confirmed on a

Google-owned source. ucp.dev lists 2026-04-08 as the latest release in its

date-based versioning scheme, not 1.0; two integration paths: Native

(default) and Embedded (approved merchants). Pairs with AP2 (reportedly

moving toward FIDO governance). Canonical: developers.google.com/merchant/ucp

and ucp.dev.

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
claude-seo run ucp_check.py https://store.example.com --json

# With endpoint reachability probes (HEAD each declared capability)
claude-seo run 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 itself is live; what's early is broad merchant adoption. Flag a literal

"version": "1.0" as invalid (UCP versions are date-based, e.g. 2026-04-08).
