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.
Use this first when Shopify rows, feed app output, Google channel state, GMC diagnostics, affected-products CSV, GCR, or item counts disagree.
Send store URL for the 1-page Feed/GMC owner mapFeed truth reportUse this when Shopify product count, Google app state, feed app output, last fetch time, or GMC item count does not line up.
Compare feed sourcesAffected-products CSVUse this when Merchant Center exports affected rows and the team needs to decide which fields, variants, or source systems own the fix.
Build the CSV evidence packetIdentifier checkerUse this when GTIN, MPN, brand, barcode, SKU, duplicate identifier, or identifier_exists decisions need row grouping before edits.
Group identifier rowsOpportunity 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.
Shopify operators using Google & YouTube, feed apps, Merchant Center, Shopping ads, Google Customer Reviews, or product identifier cleanup workflows.
Do not treat every Google Merchant Center warning as a feed-rule edit. First decide whether the blocker is product sync, product identifiers, Google Customer Reviews, merchant trust, or suspension evidence.
Shopify product count, Google & YouTube app state, feed app rows, Content API items, or GMC item count do not match.
Open the sync fix pathGTIN / MPN / brand errorsMerchant Center affected rows mention invalid GTIN, missing identifiers, MPN, brand, barcode, or identifier_exists decisions.
Group CSV rows in the checkerGCR checkout issueGoogle Customer Reviews opt-in, survey trigger, thank-you page, checkout compatibility, or program status evidence is unclear.
Check the GCR routeSuspension or appeal evidenceThe issue has moved beyond item cleanup into account status, policy proof, appeal timeline, merchant trust, or support escalation.
Build the evidence packThe report connects each visibility problem to crawl evidence, AI answer samples, competitor risk, and a concrete repair step.
Bulk field edits waste time when the real mismatch is channel inclusion, app ownership, stale fetches, or duplicate feed sources.
GTIN, MPN, brand, barcode, and identifier_exists problems should be grouped before merchants edit hundreds of variants.
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.
The hub should turn a vague Merchant Center warning into a compact evidence packet: source catalog, generated feed, Google received state, affected rows, and the review decision. Use it before changing titles, GTINs, feed rules, or appeal copy.
Store URL, Merchant Center issue type, affected-products CSV sample, and current feed source owner.
Use the 1-page Feed/GMC owner map when evidence conflicts, the feed truth report for count/source conflicts, and the identifier checker for row-level GTIN/MPN/brand issues.
Decide whether the next owner is Shopify product data, Google & YouTube, a feed app, Merchant Center rules, public product proof, GCR, or suspension evidence.
This proves what the store believes it is sending before a feed app or Google channel changes the output.
This proves whether the feed layer is transforming, omitting, duplicating, or overwriting source data.
This proves what Google actually received and whether the issue is product data, destination eligibility, GCR, or policy evidence.
This proves whether a free tool is enough or a reviewed Feed/GMC Truth Snapshot is worth requesting.

Decision needed: source owner, row grouping, reviewed snapshot, Fix Pack, or suspension evidence packMerchant 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.
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.
Invalid GTIN, missing identifiers, MPN mismatch, and identifier_exists false decisions should be grouped by product type and variant source.
Google Customer Reviews depends on account eligibility and checkout or thank-you page trigger evidence, not only Merchant Center settings.
Account, policy, product, feed, and timeline evidence should be separated before an appeal or support escalation.
The free tools should solve simple row grouping and source checks. A reviewed Google Truth Snapshot is justified when the same product issue appears differently in Shopify, GMC diagnostics, feed app mappings, GCR, public product pages, or suspension evidence.
Use this when the main question is product count, feed ownership, last fetch time, Google app status, or which system owns the mismatch.
Use this when affected-products rows need GTIN, MPN, brand, barcode, duplicate GTIN, SKU-as-MPN, or identifier_exists grouping.
Use this when CSV rows, app mapping, diagnostics screenshots, public URLs, and business policy evidence disagree.
Use this when a normal feed mismatch has become an account, appeal, policy, or merchant trust case.
Use the smallest workflow that can answer the actual Google channel question. Escalate only when the evidence spans multiple systems or a support/appeal handoff.

The audit organizes feed and policy evidence. It cannot control Google review decisions or shopping ad eligibility.
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.
No. Product count and source ownership should be checked first. Identifier cleanup helps only after the right products are reaching the feed.
It can organize evidence for product data, policy pages, account links, affected rows, and appeal timeline. It cannot guarantee a Google review outcome.
