See every featureGMC Compliance Checker reviews every product in your Shopify catalog against Google Merchant Center policy before you submit your feed. Merchants often lose their Merchant Center account without warning due to misrepresentation claims, unsubstantiated health claims, or category-specific restricted wording.
Google Merchant Center suspends stores for problems that are easy to miss: a vague refund policy, missing contact details, shipping promises that don't match your rates, or claims Google treats as misrepresentation. Unflag scans your store against the checks Google's reviewers use and explains each problem in plain English with steps to fix it, most serious first.
- Flags misrepresentation, prohibited, and restricted-content violations
- Detects unsubstantiated health, safety, and therapeutic claims
- Checks jewelry, electronics, pet, baby, and alcohol category rules
- Shows the exact policy violated and the flagged text for each issue
- Scan your whole store for problems that get Google Shopping accounts suspended
- Get a plain-English fix for every problem, ranked by how much risk it adds
- Check policies, contact details, checkout, shipping and product data in one go
- Connect Merchant Center to see Google's own warnings next to your store's issues
