Cost Guardrail (MANDATORY)

Before EVERY Merchant API call:

claude-seo run 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:

claude-seo run dataforseo_costs.py log merchant_google_products_search <cost>

Workflow

# Product search: who sells what at what price
claude-seo run dataforseo_merchant.py search "<keyword>" --marketplace google

# Seller analysis: merchant ratings and dominance
claude-seo run dataforseo_merchant.py sellers "<keyword>"

# Normalize results for analysis
claude-seo run dataforseo_normalize.py results.json --module merchant

### 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)

• 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

Cross-Skill Integration

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).
