Audit Coverage

What This Tool Checks

Product Schema

Detect whether Product markup is present and whether core fields such as name, image, brand, SKU, and offer data are clear enough for search engines.

Offer Signals

Compare price, currency, availability, and product URL signals so crawlers do not see a different product than shoppers see.

Structured Data Consistency

Catch contradictions between rendered HTML, metadata, canonical tags, and JSON-LD blocks that can lower trust in the page.

AI Search Readiness

Review whether the page gives AI answer systems enough product context to parse, compare, and recommend the item.

Schema Entity Map

Product schema examples this checker separates

A strong ecommerce product page does not treat structured data as one generic JSON-LD blob. It separates the product entity, the sellable offer, authentic review signals, and the breadcrumb path so search engines can reconcile the page with Merchant Center, snippets, and shopping surfaces.

Product entity fields

The Product entity should describe the item itself, not the category page, collection page, or marketing campaign around it.

Example signals

Product: name, image[], description, brand, sku, gtin/mpn, category

What to verify

  • check_circleProduct name and image match the visible product page.
  • check_circleBrand, SKU, GTIN, or MPN are present when the store has them.
  • check_circleVariant attributes such as color, size, material, and model are not hidden in vague copy.

Offer and merchant listing data

Offer markup should describe what a shopper can actually buy on this URL, including price, currency, availability, condition, and the canonical product URL.

Example signals

Offer: price, priceCurrency, availability, itemCondition, url, priceValidUntil

What to verify

  • check_circlePrice and priceCurrency match the rendered page and selected market.
  • check_circleAvailability is current and not contradicted by sold-out or preorder messaging.
  • check_circleOffer URL resolves to the same canonical product page Google can crawl.

Review and AggregateRating signals

Review markup is only useful when it represents genuine reviews that are visible to shoppers and consistent with the review widget or platform data.

Example signals

AggregateRating: ratingValue, reviewCount; Review: author, reviewBody, datePublished

What to verify

  • check_circleRatings are shown on the page, not only injected into hidden schema.
  • check_circlereviewCount and ratingValue match the visible review summary.
  • check_circleMultiple review apps are not outputting conflicting aggregateRating values.

BreadcrumbList context

Breadcrumb schema helps crawlers understand where the product sits in the catalog and prevents category context from being inferred incorrectly.

Example signals

BreadcrumbList: Home > Collection > Product with position values and item URLs

What to verify

  • check_circleBreadcrumb names match the visible navigation path.
  • check_circleEach breadcrumb item has a crawlable URL and a stable position value.
  • check_circleBreadcrumbs do not point to filtered or temporary collection URLs by mistake.

Common Blockers

Issues Worth Fixing First

priority_high

Missing or thin Product markup

The page has visible product information, but the structured data does not describe the product entity clearly.

priority_high

Broken Offer details

Price, currency, availability, or URL fields are missing, stale, or inconsistent with the rendered product page.

priority_high

Duplicate JSON-LD blocks

Themes, apps, and tag managers can inject multiple conflicting Product schemas on the same URL.

priority_high

Weak product attributes

Important attributes like brand, SKU, material, size, color, variant, or inventory signals are absent or too vague.

Workflow

From URL to Fix Plan

01

Paste a product URL

Use the public product page shoppers and crawlers can access, not a preview, cart, or admin URL.

02

Scan the rendered page

ShopGox checks the final product page output, including schema, metadata, content clarity, and crawler-facing signals.

03

Prioritize fixes

Use the report to decide whether the fix belongs in content, theme templates, schema apps, or platform settings.

FAQ

Questions Before You Scan

Is this only a JSON-LD validator?
expand_more
No. Generic validators check whether markup is syntactically valid. ShopGox also compares Product, Offer, Review, AggregateRating, BreadcrumbList, metadata, and visible product content so you can find contradictions that syntax validators miss.
Which schema types matter most on an ecommerce product page?
expand_more
For a sellable product page, start with Product and Offer. Then review BreadcrumbList, Review or AggregateRating when reviews are visible, and merchant listing fields such as price, availability, shipping, and return policy when your store can provide them accurately.
What fields are most often missing from product schema?
expand_more
The common gaps are brand, SKU, GTIN or MPN, image arrays, priceCurrency, availability, canonical URL, variant attributes, and review counts that match the visible review widget.
Should I add Review schema if my product has no visible reviews?
expand_more
No. Review and AggregateRating markup should reflect reviews that shoppers can see on the page. Adding hidden or unsupported ratings can create trust problems and structured data eligibility issues.
Does clean Product schema guarantee rich results?
expand_more
No. Clean structured data improves the inputs search engines can evaluate, but rich results still depend on eligibility, crawlability, policy compliance, page quality, and Google's own display decisions.
