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.

Findings (10)

Parsed Offer price and priceCurrency on Product JSON-LD across 10 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.

HTTPS enforced sitewide + HSTS (≥ 6-month max-age)https-and-hsts-enforcedHSTS

Enforce HTTPS sitewide and ship a Strict-Transport-Security header with max-age ≥ 6 months

Why this matters: AI agents and payment flows refuse plain HTTP; weak HSTS is treated as effectively no HSTS by trust-and-safety scanners.

Findings (1)

Confirmed the homepage is HTTPS (status 200), probed http://disruptiveyouth.com/ for redirect behaviour, and parsed the Strict-Transport-Security header (absent).

How: URL scheme + homepage status check, an http://host/ redirect probe through politeFetch, and a Strict-Transport-Security max-age parse (RFC 6797; ≥ 180-day threshold).

  • No Strict-Transport-Security header on the homepage responseCRITICAL

Product `image` populatedproduct-image-populatedSchema.orgMerchant

Add a resolvable image URL to every Product node

Why this matters: Agents show your product image in shopping cards; a missing image weakens or drops the listing.

Findings (10)

Read the image field on Product JSON-LD across 10 sampled product pages (0 resolve at least one URL, 0%).

How: Resolve image on each Product node into a list of URL strings (string, array, or ImageObject.url/contentUrl); require at least one non-empty URL.

GTIN coverage on PDPsproduct-gtin-populatedSchema.orgMerchant

Populate gtin on every branded Product node

Why this matters: GTINs let agents match your product to the same item elsewhere; without them you lose cross-catalog matching.

Findings (11)

Checked 20 sampled product pages for a GTIN in the Product JSON-LD (0 carry a valid GTIN, 0%).

How: Extract gtin / gtin8 / gtin12 / gtin13 / gtin14 from the first Product JSON-LD node on each PDP; validate digit length.

MerchantReturnPolicy node present on Product or Offermerchant-return-policy-presentReturnsSchema.org

Emit hasMerchantReturnPolicy on Product or Offer JSON-LD

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.

Findings (10)

Inspected hasMerchantReturnPolicy on Product/Offer JSON-LD across 10 sampled product pages (0 present, 0%).

How: On each PDP, locate the Product JSON-LD node and check for a hasMerchantReturnPolicy object/array at Product level OR Offer level. Pass band ≥ 85% coverage, partial ≥ 50%.

Emit shippingDetails (OfferShippingDetails) on Offer JSON-LD

Why this matters: Without shippingDetails, AI agents fall back to vague defaults — they can't quote your rates, destinations, or delivery windows in shopping cards.

Findings (10)

Inspected shippingDetails on Product/Offer JSON-LD across 10 sampled PDPs (0 present, 0%).

How: On each PDP, locate the Product JSON-LD node and check for shippingDetails (single object or array) at Product or Offer level. Pass band ≥ 85% coverage.

/.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.

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

    /.well-known/ucp

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.

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.

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.

  • No /.well-known/ucp profile presentHIGH

    /.well-known/ucp

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.

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.

Product JSON-LD present on PDPsproduct-jsonld-presentSchema.orgMerchant

Publish a Product JSON-LD block on every PDP

Why this matters: Product JSON-LD is how agents identify the canonical product entity without running JavaScript.

Findings (10)

Parsed JSON-LD on 20 sampled product pages for a Product node (10 found, 50%).

How: Walk each sampled PDP's parsed jsonLdBlocks, flatten @graph containers, and count the page as passing if any node has @type Product / ProductGroup / IndividualProduct / ProductModel.

NAHIGH
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.

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.

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.

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.

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.

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.

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.

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.

Why this was skipped

No UCP profile present.

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

FAILMEDIUM
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.

Findings (10)

Inspected the brand field on Product JSON-LD across 10 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.

Findings (1)

Found a homepage Organization node but its contactPoint is missing both email and telephone.

How: Parse homepage <script type="application/ld+json"> blocks, flatten @graph, and look for an Organization/OnlineStore/Store node with a contactPoint carrying email or telephone.

  • Homepage Organization node has no contactPoint with email or telephoneMEDIUM

    /

    What we expected

Why this matters: Third-party review widgets feed the ratings AI agents trust when ranking merchants.

Findings (1)

Scanned the homepage and 20 sampled PDPs for 8 review-platform asset fingerprints; none matched.

How: Substring scan of homepage and sampled PDP HTML for known review-platform asset fingerprints (judge.me, yotpo, stamped.io, reviews.io, okendo, loox, trustpilot, bazaarvoice).

  • No third-party review-platform integration detectedMEDIUM

Sitemap entries share the host of the containing sitemapsitemap-same-hostSitemap

Keep every sitemap entry on the sitemap's own host

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

Findings (5)

Compared 300 <loc> entries against their sitemap host across 3 resource(s); 6 cross-host entries found.

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

HSTS policy carries the includeSubDomains directivehsts-include-subdomainsHSTS

Skipped — HSTS itself is not enabled

Context: Without includeSubDomains, an HTTP subdomain (staging, mail, …) can be used to attack the apex's cookies.

Why this was skipped

Looked for includeSubDomains in the Strict-Transport-Security header, but HSTS itself is not enabled.

How: Parse the homepage Strict-Transport-Security header for the includeSubDomains directive (RFC 6797 §6.1.2).

  • HSTS not enabled; check https-and-hsts-enforced first.MEDIUM

    Fix https-and-hsts-enforced first — once HSTS ships, re-run this check.

NAMEDIUM
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.

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.

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.

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.

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.

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.

NAMEDIUM
Each capability has version + spec + schemaucp-capability-required-fieldsUCP

Skipped — No UCP profile present.

Context: Capabilities missing version/spec/schema can't be matched against agent support tables — agents skip them silently.

Why this was skipped

No UCP profile present.

How: For each capabilities[] entry, require non-empty string values for version, spec, and schema.

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
Every service `version` matches YYYY-MM-DDucp-service-version-date-formatUCP

Skipped — No UCP profile present; service version formats are not evaluable.

Context: Free-form version labels like `1.0` or `latest` defeat the version-pinning agents rely on, leaving them unable to negotiate the correct spec generation.

Why this was skipped

No UCP profile present; service version formats are not evaluable.

How: For each services[] entry, require version to be a string matching /^\d{4}-\d{2}-\d{2}$/.

FAILLOW
Product `aggregateRating` presentproduct-aggregate-rating-presentSchema.org

Add an AggregateRating to Product nodes when you have real reviews

Why this matters: Review ratings are a trust signal agents use to rank and filter products.

Findings (10)

Looked for a valid aggregateRating on Product JSON-LD across 10 sampled product pages (0 valid, 0%).

How: On each Product node, parse aggregateRating (or the first element if it's an array) and require ratingValue in [0,5] AND reviewCount or ratingCount ≥ 1.

Context: HSTS preload-list inclusion is the strongest downgrade protection available — first-time visits are protected too.

Why this was skipped

Looked for the preload directive in the Strict-Transport-Security header, but HSTS itself is not enabled.

How: Parse the homepage Strict-Transport-Security header for the preload directive (hstspreload.org vendor extension to RFC 6797).

  • HSTS not enabled; check https-and-hsts-enforced first.LOW

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.

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.

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
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.

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.

NAINFO

Context: An /llms.txt manifest points agents at your feed and key pages without them having to guess.

Why this was skipped

Looked for /llms.txt at the site root; the fetcher returned no file.

How: Check whether the fetcher reached an /llms.txt at the site root. Informational only — no failure path per llmstxt.org being a voluntary community convention.
