HALFCRITICAL
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.

RFC 6797 — HTTP Strict Transport Security (HSTS)
Findings (1)

Confirmed the homepage is HTTPS (status 200), probed http://icingonthering.com/ for redirect behaviour, and parsed the Strict-Transport-Security header (value: "max-age=0").

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).

  • HSTS max-age is below the 6-month minimumCRITICAL

    /parsed max-age = 0s (need ≥ 15552000s = 180 days)

    What we found

    max-age=0

    What we expected

    Strict-Transport-Security: max-age=31536000; includeSubDomains

    Bump max-age to at least 15552000 (180 days). 31536000 (1 year) is required for preload-list inclusion.

FAILHIGH
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.

  • No terms-of-service page reachable at any candidate URLHIGH

    statuses: /terms-conditions/=404, /terms/=404, /terms=404, /terms-of-service=404, /policies/terms-of-service=404

    Publish a ToS page at /terms (or your platform's standard slug) with ≥200 chars of body text.

Brand attribution on PDPsproduct-brand-attributionSchema.orgMerchant

Surface brand attribution on every PDP

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

schema.org/Product.brand
Findings (11)

Checked 20 sampled product pages for brand attribution via Product JSON-LD or visible HTML signals (0 attributed, 0%).

How: On each PDP, accept brand attribution from either (a) extractBrand on the first Product JSON-LD node OR (b) an HTML brand signal (OG product:brand, brand meta, og:brand, Microdata itemprop="brand").

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.

schema.org/Product.gtin
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.

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)

Profile is missing required key(s): signing_keys.

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

  • Required top-level key signing_keys is missingHIGH

    /.well-known/ucp

    What we expected

    Add a top-level "signing_keys" field to the JSON document (empty array/object is fine).

    Set signing_keys at the root of the JSON document.

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

Populate the conditional fields required by each service's transport

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

UCP overview — transport-conditional fields
Findings (1)

Validated 1 services with recognised transports (0 satisfy their transport's required fields).

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

Coverage

0/1 · 0%

  • Service is missing transport-conditional field(s)HIGH

    /.well-known/ucpnamespace=dev.ucp.shopping; transport=rest

    What we found

    missing: schema

    What we expected

    `endpoint` + `schema`

    Add schema to this services[] entry.

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

Skipped — Profile declares no signing_keys; JWK validation has no entries to evaluate.

Context: 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)
Why this was skipped

Profile declares no signing_keys; JWK validation has no entries to evaluate.

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.

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.

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

Inspected the brand field on Product JSON-LD across 20 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.

FAILMEDIUM
HSTS policy carries the includeSubDomains directivehsts-include-subdomainsHSTS

Add includeSubDomains to your Strict-Transport-Security header

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

RFC 6797 — HSTS `includeSubDomains` directive
Findings (1)

Inspected the homepage Strict-Transport-Security header ("max-age=0") and the includeSubDomains directive is absent.

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

  • HSTS header is missing the includeSubDomains directiveMEDIUM

    /

    What we found

    max-age=0

    What we expected

    Strict-Transport-Security: max-age=31536000; includeSubDomains

    Append ; includeSubDomains to your STS header once every subdomain you operate supports HTTPS.

FAILMEDIUM
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)

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

    "contactPoint": [{"@type":"ContactPoint","contactType":"customer service","email":"support@example.com","telephone":"+1-555-123-4567"}]

    Add a contactPoint object with at least one of email or telephone.

FAILMEDIUM
Third-party review-platform integration detectedreview-app-detectedSchema.org

Install a third-party review platform so agents see syndicated reviews on your storefront

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

schema.org/Review vocabulary
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

    none of 8 fingerprints matched across 21 sources

    Install a Judge.me / Yotpo / Loox / Okendo / Stamped / Reviews.io / Trustpilot / Bazaarvoice widget on your storefront.

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.

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

Skipped — Profile declares no capabilities; required-field checks have nothing to evaluate.

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

UCP overview — capabilities
Why this was skipped

Profile declares no capabilities; required-field checks have nothing to evaluate.

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 services declared a `spec` URL; origin matching has nothing to evaluate.

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

UCP overview — service specs
Why this was skipped

No services declared a spec URL; origin matching has nothing to evaluate.

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.

FAILLOW
Product images meet Google’s 50,000-pixel area thresholdimage-area-50k-pixelsMerchant

Upload higher-resolution product images (area ≥ 50,000 pixels)

Why this matters: Tiny product images get dropped from Google’s shopping rich-result modules and are unhelpful to AI agents quoting your product visually.

Image quality (≥50K pixels area)
Findings (11)

Inspected <img width=… height=…> attributes on 20 sampled product pages (0 have at least one image with area ≥ 50,000 px; dimensions absent from HTML are not HEAD-probed and count as indeterminate).

How: For every sampled PDP, parse <img> tags and read explicit width and height attributes; a PDP passes when at least one image has width × height ≥ 50,000. PDPs without any explicit-dimension <img> are marked indeterminate (this check does not HEAD image URLs).

HSTS policy carries the preload directivehsts-preload-directiveHSTS

Add preload to your Strict-Transport-Security header and submit to hstspreload.org

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

RFC 6797 — HSTS `preload` directive (vendor extension)
Findings (1)

Inspected the homepage Strict-Transport-Security header ("max-age=0") and the preload directive is absent.

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

  • HSTS header is missing the preload directiveLOW

    /

    What we found

    max-age=0

    What we expected

    Strict-Transport-Security: max-age=31536000; includeSubDomains; preload

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.

schema.org/AggregateRating
Findings (11)

Looked for a valid aggregateRating on Product JSON-LD across 20 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.

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

Skipped — Walked services[] for `transport: "mcp"` entries; none advertised.

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

Walked services[] for transport: "mcp" entries; none advertised.

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

FAILINFO
Apple Pay markers detected (informational)apple-pay-detectedSchema.org

Enable Apple Pay through your payment processor (informational only)

Why this matters: Apple Pay is a checkout-quality signal for human shoppers — informational only, does not affect the agent-readiness score.

Apple Pay availability — payment options observed
Findings (1)

Scanned the homepage and 20 sampled PDPs for Apple Pay markers; none matched.

How: Substring match on known Apple Pay SDK/markup signatures (ApplePaySession, apple-pay-button, /apple-developer-merchantid-domain-association) across the homepage and every sampled PDP HTML.

  • No Apple Pay markers detected on the homepage or PDPsINFO

    /

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

llmstxt.org — /llms.txt manifest
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.
