Offer price + priceCurrency validoffer-price-currency-validMerchantSchema.org

Set price as a number and priceCurrency as an ISO 4217 code

Why this matters: Agents need a price with a currency to show and compare your product.

Google merchant listing — price + priceCurrency required
Findings (11)

Parsed Offer price and priceCurrency on Product JSON-LD across 19 sampled product pages (0 valid, 0%).

How: Parse Offer price (or AggregateOffer lowPrice) as a parseable numeric price ≥ 0; require priceCurrency to match /^[A-Z]{3}$/i.

No sampled PDP returns a noindex directivepdp-not-noindexMerchant

Remove the noindex directive from every PDP

Why this matters: A noindex on the PDP makes it invisible to Google and ineligible for the merchant listing program.

Google merchant listing — indexable PDPs
Findings (20)

Sampled 20 PDP(s); 20 returned a noindex directive.

How: For each sampled PDP, inspect the HTML for <meta name="robots" content="...noindex..."> and the response headers for X-Robots-Tag: ...noindex....

Terms of service page reachableterms-of-service-page-reachableMerchant

Publish a terms of service page and link it from your site nav/footer

Why this matters: A published ToS is a baseline trust signal AI agents and ad networks use to decide whether to surface or accept a merchant.

Google merchant listing — terms of service
Findings (1)

Probed 5 candidate ToS paths (nav-discovered + platform-conventional) and none returned a 2xx body.

How: Discover candidate URLs by scoring homepage nav/footer anchors for terms/tos/legal/conditions keywords, then append platform-conventional paths; probe each with politeFetch and pass on the first 2xx with ≥200 stripped-body chars.

Why this matters: Without the entry-point return-policy node, agents can't render or quote your return terms — they fall back to platform defaults or skip your store.

Google return-policy structured data — entry-point field
Findings (11)

Inspected hasMerchantReturnPolicy on Product/Offer JSON-LD across 19 sampled product pages (0 present, 0%).

/.well-known/ucp profile is present with a `version` fielducp-profile-presentUCPUCP Profile

Publish /.well-known/ucp with at minimum a version field

Why this matters: Without `/.well-known/ucp`, Google's AI Mode can't identify your storefront as a UCP-conformant merchant.

UCP overview — profile location and shape
Findings (1)

Inspected /.well-known/ucp for a parseable JSON document with a top-level version string.

How: Confirm ctx.wellKnownUcp is non-null and carries a non-empty version string (the only universally-required UCP profile field).

  • /.well-known/ucp is not reachable or not parseable as JSONHIGH

UCP profile carries all four required top-level keysucp-profile-required-keysUCP

Add every required top-level key to the UCP profile

Why this matters: A profile missing one of the four required keys is treated as non-conformant — agent runtimes fall back to default behaviour and may skip the merchant.

UCP overview — required profile keys
Findings (1)

Wanted to inspect UCP root keys, but no profile was found.

How: Read the profile root (or top-level ucp wrapper) and verify the presence of version, services, capabilities, and signing_keys keys.

UCP profile declares a valid shopping service entryucp-shopping-service-validUCPUCP Profile

Declare a shopping service entry with a recognised transport and an HTTPS endpoint

Why this matters: Without a valid shopping service entry, agents can recognise you as a UCP merchant but have no way to fetch your catalog.

UCP overview — services declaration
Findings (1)

Wanted to walk the UCP profile's services[] for a valid shopping entry, but no profile was found.

How: List every services[] entry whose namespace is shopping (or contains shopping) and require at least one with transport ∈ {rest,mcp,a2a,embedded} AND a syntactically valid https:// endpoint.

Every signing_keys[] entry is a valid JWKucp-signing-keys-validJWKS

Make every signing_keys[] entry a JWK with kty + kty-specific params

Why this matters: Malformed JWK entries are rejected silently by agents — signed payloads cannot be verified and the merchant loses trust signal.

RFC 7517 — JSON Web Key (JWK)
Findings (1)

Wanted to validate signing_keys[], but no UCP profile was found.

How: Walk signing_keys[] and validate each entry per RFC 7517 §4.1 (kty required) + RFC 7518 §6 (kty-specific required parameters). kid is OPTIONAL per RFC 7517 §4.5 and not enforced here.

Add a mailto: email link or tel: phone link to your contact page

Why this matters: Without an email or phone on your contact page, ChatGPT and Perplexity have no escalation path to surface for shoppers.

Google merchant listing — customer-support contact info
Findings (1)

Reached the contact page at https://shop.zoeller.com/contact/ but found neither a mailto link, tel link, plain email, nor a phone-shaped number.

MerchantReturnPolicy finite-window has positive merchantReturnDaysmerchant-return-policy-finite-daysReturns

Skipped — No MerchantReturnPolicy node used the MerchantReturnFiniteReturnWindow category, so the `merchantReturnDays` check has nothing to evaluate.

Context: AI agents quote your concrete return window in shopping cards. Without `merchantReturnDays`, your policy renders as 'has a return policy' without the headline number.

Google return-policy SD — merchantReturnDays required for finite windows
Why this was skipped

No MerchantReturnPolicy node used the MerchantReturnFiniteReturnWindow category, so the merchantReturnDays check has nothing to evaluate.

How: For each MerchantReturnPolicy node whose returnPolicyCategory normalizes to MerchantReturnFiniteReturnWindow, require merchantReturnDays to be a positive number (or a numeric string > 0).

NAHIGH
MerchantReturnPolicy satisfies Option A (country+category) or B (returnLink)merchant-return-policy-option-a-or-bReturnsSchema.org

Skipped — No PDP carried a `hasMerchantReturnPolicy` node, so Option A/B shape cannot be evaluated.

Context: A policy node missing both shapes is invisible to agents — they can't render it, link to it, or quote your return terms.

Google return-policy SD — required-shape MUSTs
Why this was skipped

No PDP carried a hasMerchantReturnPolicy node, so Option A/B shape cannot be evaluated.

How: For each PDP, walk every hasMerchantReturnPolicy node (Product or Offer level) and require either (applicableCountry + returnPolicyCategory) OR a syntactically-valid merchantReturnLink URL.

NAHIGH
UCP profile Cache-Control is shared-cacheable with max-age ≥ 60sucp-cache-headers-validUCP

Skipped — No UCP profile present; Cache-Control policy is not evaluable.

Context: If your UCP profile says `no-cache`, agent runtimes re-fetch on every interaction — brittle at scale and prone to rate-limit failures.

UCP overview — profile caching
Why this was skipped

No UCP profile present; Cache-Control policy is not evaluable.

How: Parse the Cache-Control header on the /.well-known/ucp response; require public, max-age ≥ 60, and no no-store/no-cache/private.

NAHIGH
/.well-known/ucp response Content-Type is application/jsonucp-profile-content-type-jsonUCP

Skipped — No UCP profile present; Content-Type is not evaluable.

Context: Agent runtimes that gate parsing on Content-Type will skip your profile if it's served as HTML or plain text.

UCP overview — JSON profile media type
Why this was skipped

No UCP profile present; Content-Type is not evaluable.

How: Check that the Content-Type header on /.well-known/ucp starts with application/json (optionally with a charset parameter).

NAHIGH
/.well-known/ucp is publicly fetchable with no authucp-profile-no-auth-requiredUCP ProfileUCP

Skipped — No UCP profile reachable; public-fetch evaluation deferred to ucp-profile-present.

Context: Agents fetch `/.well-known/ucp` without credentials — a 401 or 403 means they never see the profile.

Google UCP merchant profile — public fetchability
Why this was skipped

No UCP profile reachable; public-fetch evaluation deferred to ucp-profile-present.

How: Confirm an unauthenticated GET to /.well-known/ucp returns a 2xx status.

NAHIGH
/.well-known/ucp returns 200 directly with no redirectsucp-profile-no-redirectsUCP

Skipped — No UCP profile present; redirect behaviour is not evaluable.

Context: Lightweight agent clients fetch `/.well-known/ucp` without following redirects — a 301/302 means they never see your profile.

UCP overview — profile location is stable
Why this was skipped

No UCP profile present; redirect behaviour is not evaluable.

How: Inspect the final HTTP status of GET /.well-known/ucp and whether any 3xx redirect was followed to reach it.

NAHIGH
Each service satisfies the transport-conditional field requirementsucp-service-transport-conditional-fieldsUCP

Skipped — No UCP profile present.

Context: A service declared with the right transport but missing endpoint/schema is unreachable — agents can't negotiate or connect.

UCP overview — transport-conditional fields
Why this was skipped

No UCP profile present.

How: For each services[] entry with a recognised transport, require the transport-conditional fields: rest/mcp → endpoint+schema; a2a → endpoint; embedded → schema.

NAHIGH
Each service `transport` is rest, mcp, a2a, or embeddeducp-service-transport-enumUCP

Skipped — No UCP profile present.

Context: An unrecognised transport leaves agents with no handler to dispatch — your service appears absent.

UCP overview — transport enum
Why this was skipped

No UCP profile present.

How: For each services[] entry, require transport to be one of: rest, mcp, a2a, embedded.

Product `brand` is a string or Brand/Organization objectproduct-brand-string-or-objectSchema.orgMerchant

Emit brand as either a string or a typed Brand object on every Product

Why this matters: Brand on every product is a primary agent filter and a required feed field.

schema.org/brand — Text | Brand | Organization
Findings (11)

Inspected the brand field on Product JSON-LD across 19 sampled product pages (0 valid as string or object, 0%).

How: On each Product node, accept brand if it's a non-empty trimmed string OR an object with a non-empty name. Objects with @type Brand/Organization but no name are rejected.

Organization/OnlineStore JSON-LD with contactPoint on homepageorganization-jsonld-with-contactSchema.org

Add an Organization (or OnlineStore) JSON-LD block to your homepage with a contactPoint

Why this matters: Organization markup with a contactPoint tells AI agents who you are and how a shopper can reach you for support.

schema.org/Organization (and OnlineStore subclass) with contactPoint
Findings (1)

Parsed the homepage JSON-LD looking for an Organization/OnlineStore node with a contactPoint, but no Organization-class node is present.

MerchantReturnPolicy merchantReturnLink URL is reachablemerchant-return-link-reachableReturns

Skipped — No MerchantReturnPolicy node carried a `merchantReturnLink` URL, so reachability has nothing to evaluate.

Context: A broken return-link makes Option B policies invisible — agents can't render or follow the link.

Google return-policy SD — merchantReturnLink reachability
Why this was skipped

No MerchantReturnPolicy node carried a merchantReturnLink URL, so reachability has nothing to evaluate.

How: Collect every unique merchantReturnLink URL across all MerchantReturnPolicy nodes; probe each once via politeFetch (failSoft). 2xx counts as reachable.

NAMEDIUM
MerchantReturnPolicy applicableCountry uses ISO 3166-1 alpha-2 codesmerchant-return-policy-applicable-country-isoReturns

Skipped — No MerchantReturnPolicy node carried `applicableCountry`, so the ISO-code check has nothing to evaluate.

Context: A non-ISO country is dropped silently; the policy looks present but never reaches the merchant-listing rich result.

Google return-policy SD — applicableCountry MUST be ISO alpha-2
Why this was skipped

No MerchantReturnPolicy node carried applicableCountry, so the ISO-code check has nothing to evaluate.

How: On each MerchantReturnPolicy node where applicableCountry is set, extract every candidate string and require every one to match /^[A-Z]{2}$/i.

NAMEDIUM
MerchantReturnPolicy returnPolicyCategory uses valid Schema.org enummerchant-return-policy-category-enumReturns

Skipped — No MerchantReturnPolicy node carried `returnPolicyCategory`, so the enum check has nothing to evaluate.

Context: An invalid category is silently dropped — your policy looks present in the source but never renders in Google's return-policy rich result.

Google return-policy SD — returnPolicyCategory enum
Why this was skipped

No MerchantReturnPolicy node carried returnPolicyCategory, so the enum check has nothing to evaluate.

How: On each MerchantReturnPolicy node where returnPolicyCategory is set, accept the bare enum name or the schema.org URL form; reject any other string.

NAMEDIUM
OfferShippingDetails shippingDestination is a valid DefinedRegionoffer-shipping-destination-validShipping

Skipped — No OfferShippingDetails node carried `shippingDestination`, so the DefinedRegion check has nothing to evaluate.

Context: Without a valid destination region, your shipping rate has no scope — Google can't decide whether to render it for a given shopper's country.

Google shipping-policy SD — shippingDestination as DefinedRegion
Why this was skipped

No OfferShippingDetails node carried shippingDestination, so the DefinedRegion check has nothing to evaluate.

How: On each OfferShippingDetails node where shippingDestination is set, require it to be a DefinedRegion (or array) and every entry to carry addressCountry matching /^[A-Z]{2}$/i.

NAMEDIUM
OfferShippingDetails shippingRate is a valid MonetaryAmountoffer-shipping-rate-validShipping

Skipped — No OfferShippingDetails node carried `shippingRate`, so the MonetaryAmount check has nothing to evaluate.

Context: An invalid rate object is silently dropped; agents can't quote your shipping cost in shopping cards.

Google shipping-policy SD — shippingRate as MonetaryAmount
Why this was skipped

No OfferShippingDetails node carried shippingRate, so the MonetaryAmount check has nothing to evaluate.

How: On each OfferShippingDetails node where shippingRate is set, require an object with numeric value/maxValue (typed or numeric string) and a 3-letter ISO 4217 currency.

Why this was skipped

Wanted to inspect sampled <loc> entries for entity escaping, but the runner did not surface any sitemap resources.

How: Sample the first 100 <loc> entries per sitemap document and check for raw &, <, or > (sitemaps.org entity escaping rules).

Context: Cross-host sitemap entries are silently dropped, so the off-host product URLs effectively don't exist for the crawler.

sitemaps.org — Sitemap file location
Why this was skipped

Wanted to compare sitemap entry hosts against the containing sitemap, but the runner did not surface any sitemap resources.

How: For each resolved sitemap resource, parse the sitemap URL's host and compare it against every parsed <loc> URL's host.

NAMEDIUM
Each service's `spec` URL origin matches its namespace authorityucp-service-spec-url-origin-matchesUCP

Skipped — No UCP profile present.

Context: A spec URL on an unrelated authority signals the service was copy-pasted from stale documentation — agents can't trust the conformance claim.

Why this was skipped

No UCP profile present.

How: For each service with a spec URL, require the URL origin to be a canonical UCP authority OR the host/path to include the namespace token.

NAMEDIUM

MerchantReturnPolicy enrichment enums use valid Schema.org valuesmerchant-return-policy-enums-validReturns

Skipped — No MerchantReturnPolicy node carried returnFees, returnMethod, or refundType, so the enum check has nothing to evaluate.

Context: Invalid enrichment values are dropped silently, leaving merchants confused about why their rendered policy is missing fields they configured.

Google return-policy SD — enum field constraints
Why this was skipped

No MerchantReturnPolicy node carried returnFees, returnMethod, or refundType, so the enum check has nothing to evaluate.

How: On each MerchantReturnPolicy node, inspect returnFees/returnMethod/refundType if set; require the bare name or schema.org URL form of a value in the corresponding Schema.org enum.

NALOW
OfferShippingDetails deliveryTime is a valid ShippingDeliveryTimeoffer-shipping-delivery-time-validShipping

Skipped — No OfferShippingDetails node carried `deliveryTime`, so the ShippingDeliveryTime check has nothing to evaluate.

Context: Without populated handling/transit times, agents can't quote a delivery window in shopping cards.

Google shipping-policy SD — deliveryTime as ShippingDeliveryTime
Why this was skipped

No OfferShippingDetails node carried deliveryTime, so the ShippingDeliveryTime check has nothing to evaluate.

How: On each OfferShippingDetails node where deliveryTime is set, require an object with at least one of handlingTime / transitTime populated as a QuantitativeValue.

NALOW
Every sitemap <loc> URL is under 2048 characterssitemap-loc-under-2048Sitemap

Context: Strict crawlers drop over-cap URLs without surfacing the error, so over-cap product entries effectively vanish.

sitemaps.org — URL length cap
Why this was skipped

Wanted to check <loc> URL lengths across every resolved sitemap document, but the runner did not surface any sitemap resources.

Context: Over-cap sitemaps are silently dropped — neither byte overflow nor entry overflow surfaces a crawler error.

sitemaps.org — Sitemap size limits
Why this was skipped

Wanted to verify each sitemap's byte size and entry count against sitemaps.org caps, but the runner did not surface any sitemap resources.

How: Check raw byte size (≤ 52,428,800 B) and entry count (≤ 50,000) for every resolved sitemap resource.

  • Transport metadata not available — runner update pendingLOW

Sitemap is served as UTF-8sitemap-utf8Sitemap

Skipped — the runner did not surface any sitemap resources with transport metadata

Context: Non-UTF-8 sitemaps are silently dropped by Search Console and trip default XML parsers used by other crawlers.

sitemaps.org — XML tag definitions (encoding)
Why this was skipped

Wanted to check the encoding of every resolved sitemap document, but the runner did not surface any sitemap resources with transport metadata.

How: Inspect every resolved sitemap document's raw byte stream for UTF-8 decodability (sitemaps.org encoding requirement).

  • Transport metadata not available — runner update pendingLOW

    /sitemap.xml

    This check activates once the runner (Task I1) populates ctx.sitemapResources with raw bytes + headers.

NALOW
UCP MCP-transport entries have valid HTTPS endpointsucp-mcp-transport-validUCP

Skipped — No UCP profile found; MCP transport validity is not evaluable.

Context: If you advertise MCP transport, agents will try to connect — broken or non-HTTPS endpoints fail silently and lose the integration.

UCP overview — transport declarations
Why this was skipped

No UCP profile found; MCP transport validity is not evaluable.

How: Filter services[] to entries where transport=mcp and validate that endpoint is an absolute https:// URL.
