INSPECTION ARCHITECTURE // DETERMINISTIC VERIFICATION

Four Technical Vectors Audited Before Every GMC Appeal

Google's automated compliance crawler evaluates structured data, HTTP responses, and legal pages simultaneously. A single mismatch across any of these four vectors triggers an immediate account suspension.

VECTOR 01 // PRICE & AVAILABILITY PARITY

DOM vs. JSON-LD Price Reconciliation

Compares the active visible price in the rendered DOM (ignoring strikethrough compare-at prices) against OpenGraph meta tags (og:price:amount) and every Offer node inside application/ld+json across both Desktop and Mobile viewports.

ASSERT: abs(dom_desktop_price - jsonld_offer_price) < 0.01

VECTOR 02 // STRUCTURED DATA INTEGRITY

Duplicate Schema Detection

Recursively flattens all @graph arrays and script blocks to count independent @type: "Product" declarations. Identifies collisions between native Shopify Liquid templates and third-party SEO apps.

ASSERT: count(jsonld_nodes where @type in ['Product', 'ProductGroup']) == 1

VECTOR 03 // MERCHANT CENTER SCHEMA SPEC

Mandatory hasMerchantReturnPolicy Verification

Verifies that your structured data explicitly declares hasMerchantReturnPolicy and shippingDetails, and cross-checks numeric handling/transit day ranges and return windows across your Shipping, Refund, and FAQ pages.

ASSERT: Offer.hasMerchantReturnPolicy != null && Policy.nojs_render == True

VECTOR 04 // CORPORATE ENTITY VERIFICATION

4-Pillar Business Identity Check

Audits your Footer navigation and Contact page in static HTML to confirm the presence and cross-page consistency of all four required identity signals: Registered Legal Name, Physical Street Address, Direct Phone Number, and Custom-Domain Email.

ASSERT: [LegalName, StreetAddress, Phone, DomainEmail] present in Static HTML

Inspect This Case's Redacted PDF

"We spent three weeks locked out of Google Shopping for 'Misrepresentation' after hiring two agencies that only gave us generic checklist advice. ZKR Studio's unauthenticated crawler pinpointed the exact root cause in under 4 minutes: a legacy SEO app injecting a duplicate @type:Product JSON-LD node and a $0.95 rounding mismatch between our mobile DOM and schema offers. We applied their redacted Liquid patch, submitted our appeal, and our GMC account was reinstated in 48 hours. Beyond unlocking our ads, cleaning the duplicate schema tree pushed our organic rich-snippet CTR up by 34% within two weeks."
