4 checks couldn't run on this store — each is listed below with the reason. Your score reflects only what we could verify.

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://coeursports.com/ for redirect behaviour, and parsed the Strict-Transport-Security header (value: "max-age=7889238").

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 = 7889238s (need ≥ 15552000s = 180 days)

    What we found

    max-age=7889238

    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
Each PDP carries at most one Product JSON-LD nodepdp-single-product-pageMerchant

Emit a single Product JSON-LD node per PDP

Why this matters: Duplicate Product nodes on a single PDP cause Google's merchant scraper to drop the listing or pick the wrong variant.

Google merchant listing — single product per page
Findings (20)

Sampled 20 PDP(s); 20 carried multiple Product JSON-LD nodes.

How: For each sampled PDP, count JSON-LD nodes whose @type is Product or whose @type array contains Product. Each PDP must expose at most one.

FAILHIGH
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.

FAILHIGH
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.

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

Skipped — the runner did not surface transport metadata

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

Wanted to inspect the UCP profile's Cache-Control header, but the runner did not surface transport metadata.

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

  • Transport metadata not available — runner update pendingLOW

    /.well-known/ucp

    This check activates once the runner (Task I1) populates ctx.wellKnownUcp.cacheControl.

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
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=7889238") 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=7889238

    What we expected

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

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

FAILMEDIUM
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.

sitemaps.org — Sitemap file location
Findings (5)

Compared 776 <loc> entries against their sitemap host across 7 resource(s); 5 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.

  • Cross-host <loc> — sitemap host is coeursports.com but entry is on www.coeursports.comMEDIUM

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.

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=7889238") 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=7889238

    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 (5 valid, 25%).

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.

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

    /

    Enable Apple Pay in your payment processor's dashboard (Stripe / Adyen / Braintree). Informational only — does not affect the score.
