Google Truth hub

Google Merchant Center and Shopify Feed Audit Tools

Diagnose Shopify to Google Merchant Center feed mismatches, product count gaps, affected items, GTIN, MPN, brand, identifier_exists, Google Customer Reviews, and suspension evidence before rewriting feed rules.

Why this page exists

Opportunity records and community threads cluster around Shopify products not syncing, invalid GTIN, missing identifiers, MPN mismatch, Google Customer Reviews checkout issues, and suspension timelines. This hub connects those long tails to one Google evidence path.

Who it is for

Shopify operators using Google & YouTube, feed apps, Merchant Center, Shopping ads, Google Customer Reviews, or product identifier cleanup workflows.

What the audit checks

The report connects each visibility problem to crawl evidence, AI answer samples, competitor risk, and a concrete repair step.

Feed issues need source ownership first

Bulk field edits waste time when the real mismatch is channel inclusion, app ownership, stale fetches, or duplicate feed sources.

Medium
Identifier cleanup is a grouped workflow

GTIN, MPN, brand, barcode, and identifier_exists problems should be grouped before merchants edit hundreds of variants.

Free Shopify to GMC feed truth report

Start with product counts and affected rows. The tool helps decide whether the issue belongs in Shopify, the Google app, a feed app, GMC diagnostics, or identifier cleanup before a reviewed snapshot or focused audit.

  • Compare Shopify export count with GMC item count and affected row count.
  • Separate feed ownership from product-field errors.
  • Group GTIN, MPN, brand, barcode, and identifier_exists problems before bulk edits.
  • Collect GCR and suspension evidence separately from normal feed mismatch rows.
Source ownership

Find the owner before changing the feed

Merchant Center problems often look like field problems while the real issue is ownership: Shopify product state, Google app sync, feed app rules, Content API, supplemental feed, or policy evidence.

Product count mismatch

Compare Shopify products and variants against GMC items before editing titles, GTINs, or feed rules. A count gap usually means sync scope or channel inclusion needs review.

Identifier errors need grouping

Invalid GTIN, missing identifiers, MPN mismatch, and identifier_exists false decisions should be grouped by product type and variant source.

GCR is a checkout evidence issue

Google Customer Reviews depends on account eligibility and checkout or thank-you page trigger evidence, not only Merchant Center settings.

Suspension work needs an evidence pack

Account, policy, product, feed, and timeline evidence should be separated before an appeal or support escalation.

What this Google truth audit cannot guarantee

The audit organizes feed and policy evidence. It cannot control Google review decisions or shopping ad eligibility.

FAQ

Questions store owners ask before ordering an audit.

Why are Shopify products not syncing to Google Merchant Center?

Common causes include channel exclusion, app sync delay, third-party feed ownership, Content API conflicts, stale fetches, missing identifiers, variant-level data gaps, or account policy issues.

Should I fix GTIN, MPN, and brand before checking product counts?

No. Product count and source ownership should be checked first. Identifier cleanup helps only after the right products are reaching the feed.

Can this help with Google Merchant Center suspension?

It can organize evidence for product data, policy pages, account links, affected rows, and appeal timeline. It cannot guarantee a Google review outcome.
