27 checks couldn't run on this store — each is listed below with the reason. Your score reflects only what we could verify.
Skipped — No PDP carried a Product JSON-LD node, so there is nothing to inspect for Offer price + priceCurrency.
Context: Agents need a price with a currency to show and compare your product.
Why this was skipped
No PDP carried a Product JSON-LD node, so there is nothing to inspect for Offer price + priceCurrency.
How: Parse Offer price (or AggregateOffer lowPrice) as a parseable numeric price ≥ 0; require priceCurrency to match /^[A-Z]{3}$/i.
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 (4)
Parsed JSON-LD on 4 sampled product pages for a Product node (0 found, 0%).
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.

Surface brand attribution on every PDP
Why this matters: Brand on every product is a primary agent filter and a required feed field.
Findings (4)
Checked 4 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").

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 (4)
Checked 4 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.
Coverage

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)
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_keysis missingHIGHWhat we expected
Add a top-level "signing_keys" field to the JSON document (empty array/object is fine).Set
signing_keysat the root of the JSON document.
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).
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.
Skipped — No PDP carried a Product JSON-LD node, so there is nothing to inspect for `hasMerchantReturnPolicy`.
Context: 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.
Why this was skipped
No PDP carried a Product JSON-LD node, so there is nothing to inspect for hasMerchantReturnPolicy.
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%.
Skipped — No PDP carried a resolvable Offer, so there is nothing to inspect for `availability`.
Context: Agents suppress out-of-stock or ambiguous items; a valid availability URL keeps you eligible.
Why this was skipped
No PDP carried a resolvable Offer, so there is nothing to inspect for availability.
How: On each Offer, accept availability only if it matches one of the canonical Schema.org ItemAvailability IRIs (http or https, trailing slash optional).
Skipped — No PDP carried a Product JSON-LD node, so there is nothing to inspect for `shippingDetails`.
Context: Without shippingDetails, AI agents fall back to vague defaults — they can't quote your rates, destinations, or delivery windows in shopping cards.
Why this was skipped
No PDP carried a Product JSON-LD node, so there is nothing to inspect for shippingDetails.
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.
Skipped — No PDP in the sample carried a Product JSON-LD node, so there is nothing to inspect for `image`.
Context: Agents show your product image in shopping cards; a missing image weakens or drops the listing.
Why this was skipped
No PDP in the sample carried a Product JSON-LD node, so there is nothing to inspect for image.
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.
Skipped — No PDP in the sample carried a Product JSON-LD node, so there is nothing to inspect for `name`.
Context: A product's name is the minimum an agent needs to list it.
Why this was skipped
No PDP in the sample carried a Product JSON-LD node, so there is nothing to inspect for name.
How: On each PDP with a Product JSON-LD node, require name to be a string of length > 0 after trimming.
Skipped — No PDP carried a Product JSON-LD node, so there is nothing to inspect for `offers`.
Context: Without an Offer, agents can't see that the product is for sale.
Why this was skipped
No PDP carried a Product JSON-LD node, so there is nothing to inspect for offers.
How: On each Product node, require a resolvable Offer (or first Offer inside an AggregateOffer) via findOffer.
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.
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
This check activates once the runner (Task I1) populates ctx.wellKnownUcp.cacheControl.
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.
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.
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
"contactPoint": [{"@type":"ContactPoint","contactType":"customer service","email":"support@example.com","telephone":"+1-555-123-4567"}]Add a contactPoint object with at least one of
emailortelephone.
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 1585 <loc> entries against their sitemap host across 6 resource(s); 65 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 optimumnutrition.com but entry is on www.optimumnutrition.comMEDIUM

Add a Sitemap: line to robots.txt
Why this matters: Declaring the sitemap in robots.txt is the simplest way to point every crawler at your full product list.
Findings (1)
Read robots.txt and looked for a Sitemap: directive; none were declared.
How: Read parsed Sitemap: directives from robots.txt (sitemaps.org / RFC 9309 implementation note).
- robots.txt has no Sitemap: directiveMEDIUM
/robots.txt0 Sitemap: lines parsed
What we expected
Sitemap: https://yourdomain.com/sitemap.xmlAdd a top-level
Sitemap:line pointing at your XML sitemap (or sitemap index).
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.
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}$/i.
Skipped — No MerchantReturnPolicy node carried `returnPolicyCategory`, so the enum check has nothing to evaluate.
Context: An invalid category is silently dropped — your policy looks present in the source but never renders in Google's return-policy rich result.
Why this was skipped
No MerchantReturnPolicy node carried returnPolicyCategory, so the enum check has nothing to evaluate.
How: On each MerchantReturnPolicy node where returnPolicyCategory is set, accept the bare enum name or the schema.org URL form; reject any other string.
Skipped — No OfferShippingDetails node carried `shippingDestination`, so the DefinedRegion check has nothing to evaluate.
Context: Without a valid destination region, your shipping rate has no scope — Google can't decide whether to render it for a given shopper's country.
Why this was skipped
No OfferShippingDetails node carried shippingDestination, so the DefinedRegion check has nothing to evaluate.
How: On each OfferShippingDetails node where shippingDestination is set, require it to be a DefinedRegion (or array) and every entry to carry addressCountry matching /^[A-Z]{2}$/i.
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.
Skipped — No PDP carried a Product JSON-LD node, so there is nothing to inspect for `brand`.
Context: Brand on every product is a primary agent filter and a required feed field.
Why this was skipped
No PDP carried a Product JSON-LD node, so there is nothing to inspect for brand.
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.
Skipped — No PDP carried a Product JSON-LD node, so there is nothing to inspect for `description`.
Context: Agents quote your description to answer shopper questions; an empty description gives them nothing to work with.
Why this was skipped
No PDP carried a Product JSON-LD node, so there is nothing to inspect for description.
How: Read description on each Product node; strip HTML tags and collapse whitespace; require length > 0.
Skipped — No PDP carried a Product JSON-LD node, so there is nothing to inspect for `sku`.
Context: A stable SKU lets agents track and re-identify your product across catalogs.
Why this was skipped
No PDP carried a Product JSON-LD node, so there is nothing to inspect for sku.
How: On each PDP with a Product node, accept sku if it is a non-empty trimmed string or a number.
Skipped — No PDP carried a Product JSON-LD node, so there is nothing to inspect for placeholder titles.
Context: Placeholder titles like Default Title make products look broken to agents.
Why this was skipped
No PDP carried a Product JSON-LD node, so there is nothing to inspect for placeholder titles.
How: Read name on the first Product JSON-LD node. Fail if empty, matches a known placeholder list (Default Title / Untitled / Product N / sample / test / draft / placeholder), or matches slug shape (lower-case alnum + at least one hyphen).
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.
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.
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.
Findings (4)
Inspected <img width=… height=…> attributes on 4 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).
Coverage

Skipped — No PDP carried a Product JSON-LD node, so there is no eligible PDP to inspect for BreadcrumbList.
Context: Breadcrumbs help agents understand where a product sits in your catalog.
Why this was skipped
No PDP carried a Product JSON-LD node, so there is no eligible PDP to inspect for BreadcrumbList.
How: Search every JSON-LD block on each PDP for @type: BreadcrumbList with a non-empty itemListElement.
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.
Skipped — No PDP carried a resolvable Offer, so there is nothing to inspect for `itemCondition`.
Context: When you declare itemCondition, agents and Google require a canonical Schema.org IRI; free-text values get ignored.
Why this was skipped
No PDP carried a resolvable Offer, so there is nothing to inspect for itemCondition.
How: On each Offer: if itemCondition is omitted, count as pass (Google defaults to NewCondition). If present, accept only when it matches a canonical Schema.org ItemCondition IRI.
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.
Skipped — No PDP carried a Product JSON-LD node, so there is nothing to inspect for `aggregateRating`.
Context: Review ratings are a trust signal agents use to rank and filter products.
Why this was skipped
No PDP carried a Product JSON-LD node, so there is nothing to inspect for aggregateRating.
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.
Skipped — No PDP carried a Product JSON-LD node, so there is nothing to inspect for title quality.
Context: Empty or all-caps product titles signal low quality to agents and trigger Google Merchant Center policy flags.
Why this was skipped
No PDP carried a Product JSON-LD node, so there is nothing to inspect for title quality.
How: Read name on the first Product JSON-LD node. Fail if missing/empty after trimming OR if the string contains letters and they're all upper-case.
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.
Findings (1)
Scanned the homepage and 4 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.
Enable Google Pay through your payment processor (informational only)
Why this matters: Google Pay is a checkout-quality signal for human shoppers — informational only, does not affect the agent-readiness score.
Findings (1)
Scanned the homepage and 4 sampled PDPs for Google Pay markers; none matched.
How: Substring match on known Google Pay SDK/markup signatures (pay.google.com/gp/p/js/pay.js, google.payments.api, <google-pay-button) across the homepage and every sampled PDP HTML.
- No Google Pay markers detected on the homepage or PDPsINFO
