E-commerce SEO Analysis

Comprehensive product page optimization, marketplace intelligence, and competitive pricing analysis. Works standalone (on-page + schema) and with DataForSEO Merchant API for live Google Shopping and Amazon data.

Commands

Command Purpose DataForSEO?
/seo ecommerce <url> Full e-commerce SEO analysis of a product page or store Optional
/seo ecommerce products <keyword> Google Shopping competitive analysis Required

1. Product Page Analysis (No DataForSEO Needed)

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

Workflow

1. "${CLAUDE_PLUGIN_ROOT}/scripts/claude-seo" run render_page.py <url> --mode auto → raw/rendered HTML
2. "${CLAUDE_PLUGIN_ROOT}/scripts/claude-seo" run parse_html.py --url <url>   → SEO elements
3. Analyze product-specific signals (below)

2. Google Shopping Intelligence (DataForSEO Merchant API)

Live competitive analysis from Google Shopping results.

Cost Guardrail (MANDATORY)

Before EVERY Merchant API call:

"${CLAUDE_PLUGIN_ROOT}/scripts/claude-seo" run dataforseo_costs.py check merchant_google_products_search

After each call:

"${CLAUDE_PLUGIN_ROOT}/scripts/claude-seo" run dataforseo_costs.py log merchant_google_products_search <cost>

Workflow

# Product search: who sells what at what price
"${CLAUDE_PLUGIN_ROOT}/scripts/claude-seo" run dataforseo_merchant.py search "<keyword>" --marketplace google

# Seller analysis: merchant ratings and dominance
"${CLAUDE_PLUGIN_ROOT}/scripts/claude-seo" run dataforseo_merchant.py sellers "<keyword>"

# Normalize results for analysis
"${CLAUDE_PLUGIN_ROOT}/scripts/claude-seo" run dataforseo_normalize.py results.json --module merchant

3. Amazon Marketplace (DataForSEO)

Cross-marketplace intelligence comparing Google Shopping and Amazon.

Cost Guardrail (MANDATORY)

"${CLAUDE_PLUGIN_ROOT}/scripts/claude-seo" run dataforseo_costs.py check merchant_amazon_products_search

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

Workflow

# Amazon product search
"${CLAUDE_PLUGIN_ROOT}/scripts/claude-seo" run dataforseo_merchant.py search "<keyword>" --marketplace amazon

# Cross-marketplace comparison
"${CLAUDE_PLUGIN_ROOT}/scripts/claude-seo" run dataforseo_merchant.py compare "<keyword>"

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

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)

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.
  7. If aggregateRating present: ratingValue and reviewCount required
  8. Do not include fake reviews or undisclosed incentivized reviews in visible content or structured data. Clearly and prominently disclose incentives.

seo-dataforseo Organic keyword rankings for gap analysis
seo-technical Core Web Vitals for product pages (LCP on hero image)

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_PLUGIN_ROOT}/scripts/claude-seo" run ucp_check.py https://store.example.com --json

# With endpoint reachability probes (HEAD each declared capability)
"${CLAUDE_PLUGIN_ROOT}/scripts/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).
