Shopify Schema Markup Tool | Automate Structure Data

01 · The most common error

The "offers / review / aggregateRating" error

If you've opened Search Console and seen "Either 'offers', 'review', or 'aggregateRating' should be specified" - or "Invalid items can't be used to generate rich results" - you're not alone. It's the single most common Shopify structured-data error.

In most cases it means your theme's Product schema is missing a required field, so Google throws out the markup entirely and your product loses rich-result eligibility.

✓ We fix this by populating the missing properties on every product and variant, so the error clears and your listings qualify for rich results again.

02 · Duplicate & conflicting

Theme, review app & SEO app all writing Product schema

A common issue on Shopify: your theme outputs Product schema, your review app adds its own, and an SEO app adds a third - so Google sees the same product marked up two or three times. The result is duplicate-value errors like "duplicate Brand" and markup Google can't trust.

The usual advice is to uninstall apps until the conflict disappears. We take a cleaner path.

✓ We fix this by detecting existing schema sources and generating one consolidated, validated block - so you get complete markup without two systems fighting each other.

03 · Variant-level pricing & stock

One Offer applied to every variant

Many themes output a single Offer for the default variant and apply it to the whole product. If one variant is $20 and another is $100, Google may show $20 across all of them - and Merchant Center flags the mismatch.

We fix this with variant-aware schema, plus the ProductGroup markup Google expects for multi-variant products.

✓ We fix this by generating variant-level Offers with the correct price, availability, and identifier for each option.

04 · Merchant Center disapprovals

"Price mismatch" that's really a schema problem

A "Mismatch between price in landing page and feed" disapproval often isn't a feed problem at all. Google cross-references your structured data against your product feed, and in 2026 that check is stricter than ever.

If your JSON-LD says one price or still says InStock on a sold-out variant, Merchant Center trusts the markup over the feed and disapproves the SKU.

✓ We fix thisby keeping your schema in sync with real inventory and pricing - so markup and feed always agree.

05 · Missing Brand, GTIN & AI Signals

The properties AI engines look for

Shopify's default schema frequently skips brand - even when your Vendor field is filled - along with GTIN, MPN, material, color, and individual review markup. AI shopping assistants treat schema completeness as a trust signal.

For stores without barcodes, we handle the "no GTIN" case correctly instead of emitting empty values Google reads as invalid.

✓ We fix this so your product data is eligible for rich results and legible to ChatGPT, Gemini, and Google's AI Overviews.
