What This Tool Checks
App-Injected Metadata
Identify schema, review, breadcrumb, or metadata conflicts caused by SEO apps, review apps, page builders, custom Liquid, and tag manager scripts.
Variant and Offer Data
Check whether variant-specific price, availability, SKU, image, variant URL, canonical, and Offer markup describe the same purchasable item.
Markets and Canonicals
Spot localized URL, hreflang, canonical, currency, language, and market-specific product signal drift before Google crawls the wrong product context.
Shopify Conflict Map
Where Shopify product schema usually breaks
Shopify stores rarely fail because there is no schema at all. They fail because theme Liquid, SEO apps, review apps, variant logic, and Shopify Markets can each describe the same product differently. This checker looks for the layer that is creating the conflict.
Theme Liquid output
Most Shopify themes emit Product JSON-LD from product templates or theme snippets. That output can become stale when templates, metafields, or product media change.
Example signals
Theme layer: main-product.liquid, product.json, product media, metafields, selected variantWhat to verify
- check_circleTheme schema uses the live product title, featured media, vendor, SKU, and current offer data.
- check_circleThe template does not output collection or placeholder data on product URLs.
- check_circleTheme updates have not left old schema snippets active in custom Liquid blocks.
SEO apps and injected JSON-LD
SEO apps can improve missing fields, but they can also inject a second Product, Organization, BreadcrumbList, or Offer block that competes with the theme.
Example signals
Injected layer: app scripts, tag manager JSON-LD, duplicate Product or BreadcrumbList blocksWhat to verify
- check_circleOnly one authoritative Product entity describes the product page.
- check_circleApp-injected schema does not contradict theme price, availability, or canonical URL.
- check_circleOld SEO app snippets are removed after app migration or uninstall.
Review app ratings
Review widgets often load after the theme and may publish their own AggregateRating or Review markup. The visible rating and the schema rating need to agree.
Example signals
Review layer: aggregateRating.ratingValue, reviewCount, review widget, imported reviewsWhat to verify
- check_circleThe review count in schema matches the visible widget count.
- check_circleImported or syndicated reviews are not duplicated across multiple apps.
- check_circleReview markup is attached to the same Product entity as the theme schema.
Variants and Offer logic
Variant-heavy Shopify products can expose one visible selected variant while schema, metadata, or scripts describe a different SKU, price, or availability state.
Example signals
Variant layer: selected_or_first_available_variant, variant URL, SKU, price, availabilityWhat to verify
- check_circleSelected variant price and availability match what crawlers read.
- check_circleVariant URLs, canonical tags, and Offer URLs do not create duplicate product entities.
- check_circleOut-of-stock variants do not overwrite the availability of in-stock variants.
Markets, currency, and hreflang
Shopify Markets can localize currency, copy, URLs, and theme settings. Schema needs to agree with the market page Googlebot is crawling.
Example signals
Markets layer: localized URL, priceCurrency, canonical, hreflang, market overridesWhat to verify
- check_circlepriceCurrency matches the localized market page, not only the store default.
- check_circleCanonical and hreflang point to the right language and market equivalents.
- check_circleMarket overrides do not hide schema-critical product blocks or app widgets.
Common Blockers
Issues Worth Fixing First
Theme and app duplication
Themes, SEO apps, review apps, and tag managers may output competing Product schemas, review data, breadcrumbs, or metadata.
Variant mismatch
The visible selected variant can differ from the price, availability, SKU, image, or Offer URL that crawlers read.
Missing brand or SKU
Shopify stores often ship basic schema but miss brand, SKU, GTIN, product type, variant attributes, shipping, or return facts that make products easier to compare.
Localized signal drift
Markets pages can send mixed currency, language, canonical, hreflang, app visibility, or product entity signals.

FAQ
Questions Before You Scan
Does Shopify already add product schema?expand_more
Most modern Shopify themes add basic Product and Offer markup, but that does not mean the final page is clean. Apps, custom Liquid, variants, review widgets, and Markets settings can still create duplicate or contradictory structured data.
Why do SEO apps sometimes create schema problems?expand_more
An SEO app may add missing JSON-LD while the theme keeps its original schema active. If both describe different prices, URLs, ratings, or availability, crawlers may see two competing product entities on one URL.
Should Shopify variants be marked up as one Offer or multiple offers?expand_more
The right answer depends on how the product page exposes variants. The important part is consistency: the visible selected variant, variant URLs, SKU, price, availability, and Offer markup should not describe different products.
How do Shopify Markets affect product schema?expand_more
Markets can change currency, language, copy, layout, and app visibility. A market page should have schema, canonical, and hreflang signals that match that market instead of silently falling back to the store default.
Where should I fix Shopify schema issues?expand_more
Fix product facts in Shopify product fields or metafields, template output in theme Liquid, duplicate markup inside SEO or review apps, and market-specific drift inside Markets settings or translation apps.
Can this checker replace a Shopify SEO app?expand_more
No. ShopGox checks the final storefront output from the outside. It helps you see whether the theme, apps, variants, and Markets settings agree, then you can fix the right layer inside Shopify or the relevant app.
